Why yes,, yes I do. I haven't checked it out yet, but I started getting into multirotors not quite two years ago and am very interested in learning more about helicopters and fixed wing scale models etc. This looks like it might be a good little first helicopter, but I'll defer a purchase decision until I've checked out your site. Thanks!
John just got mine in the mail right after watching this!! Wow thank you so much!! Im a C5-6 quadriplegic with limited hand function,but im graduating/retiring my RC brushless trucks,buggs,boats to my 8 nephew's and flying with the eagles!! Knowledge truly is Power!! Again thanks for yours!! Be well, Chris McAleer
Glad to see your video. When I started flying I used to go to your website and passed it along to other friends. Thank you for your time and glad to see the passion for this great hobby continues.
thank you thank you! This is the closest I can find to set up this gem on my T6J that's in English and it was actually exactly what I needed and more, very nicely done thank you for taking the time to do this thoughtfully and thoroughly
stupid me i saw few videos of K124 fell in love with it and bought it. good lord it is so tough to get it off the ground and all these setting for newbie is complicated like hell. i almost put in my shelf as a show piece then one day i took courage to start playing around with the control setting and man i got the hang of it. now i am able to fly almost comfortably inside my house (small rooms) but yet not brave enough to get out. just wanted to tell folks who sell this after getting just be patient and keep going at it.
I must say you're video on this bird has showed me more about rc helicopters that has kind of taken the fear of purchaseing and flying one. I had 2 Blade helos a few years ago and all i did was crash and by parts to the point I just gave up on helos. Thank you!
some info, for novice heli flyers. do NOT thumb the right stick. because, it is Impossible to Know, by FEEL, where 'center stick' is. crashes should be fewer, if a pilot continuously allows the right stick to return to center. this can be done by loosely 'trapping' the stick between thumb and finger. use a neck strap. use a good tx grip. keep elbows mostly straight. hold tx near waist level. fully support tx with left hand.. cheers
@@purplefurture6960 The Blade 70 S is a good one. It's tiny and pretty quiet, and flies well indoors. It's fixed pitch though, so no inverted flight. If you want a scale body, the Esky F150 V2 has the same internals and a Bell 222 body.
Yes, that was very helpful. I ordered mine today with spare tail rotor motor. Banggood did not offer a battery in the parts list. Motion RC has them listed but out of stock for now.
why any thumbs down..can't understand..assuming they are not referring to Heli - but the reviewer....great video as always John...been a fa n for many years....something special about flying helicopters !!!!
A beautiful scale micro. Helimax had their version in White, Black & Gold but no XK style bind button . I better get this one, too. 3yrs later & two are on their way ,one of which mechanics will go into old non FHSSS Helimax fuselage.

Great review! I learned to fly helis on the xk 124 and phoenix sim. The xk 124 is really rugged but the cable to the light in the front gave up pretty early.
Nice Rc Helicopter review very detailed video. My K124 i bought 2019 february and still Good shape and the spare parts the only but is a li-po battery. I planning to buy a new battery online to use it again
Hi, I’ve got a XK K100 which I’m trying to get working on my FrSky Q7 with a multi protocol module. How do you set these up? I’ve bound the heli to the transmitter but the channels don’t map across properly. Just does what it wants. Only channel that responds as expected is the throttle and the rotor pitch (which I have on a 3 way switch).
I think this heli is better than k110 even m1 for someone don't fly 3D. It's much easier to see the position in the air with the scale fuselage. Four blades provide more float in the air than 2 blades. The only problem is overheating if keep hovering for all the time. But if you just fly around like me, this won't be an issues. It takes the heli less for flying forward than hovering. You can fly one battery right after another one.
and yet another great micro heli review by the guy who is „guilty“ of dragging me into this addictive hobby. 🤓👍 Thanks John and greetings from the other side of the pond. cheers Ruedi
Thank you for a great review. A drone is good, but the movement of the helicopter is still interesting. I used to fly a helicopter a little before, but it was difficult and didn't work.
John, I LOVE the scale birds as well. I have BOTH the K-123 and K-124 and a Heli-Max EC-135 . as well, I have one of the Radios however I use my Taranis X9D Plus. Would love to look at ALL of your Open TX programing for these little birds. also do you know if there are any scale fuselages for the small blade helis, Nano CPS/X, 130S, or even the Blade SR and 300X Thanks Kelly in San Antonio
Hi Kelly, I do show all the OpenTX settings near the end of the video (starting at time index 20:25). I don't think anyone makes micro scale fuselages for the smaller Blade stuff.
Hey John, love this video! 👍🏻🚁 I’ve managed to get my K124 a bit more control for indoor flight during lockdown. She’s still very twitchy, the X6 transmitter has a gyro setting 0-100. Should I have a high value or a low value for better stability? Thanks buddy! ✅
@@Rchelicopterfun Thanks for getting back to me John. I’ve just watched your XK X6 Transmitter Review ( ua-cam.com/video/lzW9m8899Tk/v-deo.html ) great video! Learnt a lot 👍🏻 It IS my first programmable collective heli radio (glad you approve). Regarding channel 5, I understand the toggle switch selects gyro mode/self level mode but when I go into settings > Gyro, I can dial the wheel from 0 - 100 and press enter. Surely this a variable control over gyro sensitivity?
This is a great little helicopter I love the way you go into detail on everything. I have a question John, I can't for the life of me figure out why I cannot get my helicopter to lift off I've got a new battery in it I've checked everything everything's even something to do with the pitch in the radio and I'm not sure what I'm doing wrong I've adjusted the trims I've adjusted everything I can think of and I cannot get it to lift off the ground it's like I need more pitch in my blades but I can't get it can you please help me
@Michael - I cover this lack of lift question as it's one of the most common ones I get on my RC Helicopter Lift page: www.rchelicopterfun.com/rc-helicopter-lift.html As that page explains, the two primary reasons any collective pitch RC helicopter will not lift off is 1. lack of head speed or 2. lack of collective blade pitch angle (or of course a combination of both). I go over things to check for both possibilities on that page. The two most common is you need to setup your pitch curve to produce more collective or setup your throttle curve to produce more head speed. That is assuming there is not something else mechanically or electrically wrong with the helicopter preventing adequate collective pitch such as a separated swashplate, or electrically such as a weak motor or faulty ESC.
Same as most small helis. Full travel in one direction (ie -100%) to full travel in the other direction (ie. +100%) on channel 5. This is basically an on/off channel 5 setup (ie. turns self level on or off and is a 2 position setting only - nothing proportional). Yes, manual is backwards; self-level (6G) has to be turned on to enter accelerometer calibration mode not off as is stated in the manual (at least the two manuals I have). No, never was able to enter self level calibration mode. Did a separate video on that: ua-cam.com/video/ZuTbwYgkm40/v-deo.html I would think they have fixed the issue however by now?
Yes they are. Here's a page on my website that explains why collective pitch helicopter are harder: www.rchelicopterfun.com/are-rc-helicopters-hard-to-fly.html
Hi Patrick, I don't use one on these small micros - there is nothing small enough to fit them. I use a simple cardboard/similar wedge gauge and the interpolation method as I outline in my setup & tips ebook in chapter 3 (Micro CP setup).
Hello John, I ask you if you can tell me which XK RC helicopter is better: the K123 or the K124 in control and everything, it would help me a lot in my decision, thank you.
Six of one, half a dozen of the other. They both have pros and cons as outlined in both video reviews I did on them. K124 flies a little bit better (anecdotal) and looks a little better (subjective), but it's more fragile (fact) and harder to see (fact).
Thanks John for this review on this one and the XK K123. I have both using the XK-6 tx that comes with them. Just wondering if one came with yours if you would do a super smooth scale flying tx -set up using the XK-6 tx. If not, I'll do some youtube searching to find one. Thanks again :)
I received the BNF (FTR) versions of both the K123 & 124, so no K6 radio. With that said, radio setup is radio setup. The same values I talk about in the video can be used on any radio (with the note that OpenTX like Spektrum & JR uses positive expo to shallow out mid stick output whereas Futaba and the K6 need negative expo. I state the collective ranges I use in my 3 flight modes so you would simply alter your pitch curves in your K6 to achieve similar collective ranges (about -2 to about +9 for these micro scalers is what I personally like). D/R is largely personal preference just as I mention in my setup & ebook for collective pitch RC helicopters : www.rchelicopterfun.com/rc-helicopter-tips.html Smooth scale flying style as you likely know is also largely up to the individual flying to pull off. I've been flying scale RC helis for over 20 years now and it does take practice to mimic full size heli behavior - more so on these little light weight micros over larger 600-800 size machines where mass & inertia are your friends.
@@Rchelicopterfun Ok John, time for me to study up and maybe consider getting you ebook. I did get your beginning book on the SR-120 a few years back. I probably need to read that again....I'm retired now so I'm looking forward to spending more time doing this. Thanks much. :)
Hi John, been binge watching your videos and might even buy your books as the videos have helped me alot so far! One thing I don't quite understand in opentx tho is, how can I setup the gyro to about 30-40% output for more of a scale like flying, but still have all the control over the heli myself? If its at +/- 100 doesn't that either fully activate/disable gyro? I don't want it to be totally aggressive.
Best to contact me through my website for setup specific questions like this. The very short answer however is channel 5 output simply turns self level help on or off. You are not disabling normal gyro operation, only the accelerometer operation (accelerometer sensors are what enable self level). There is no gyro gain adjustability. If you want a scale behaving heli, you would never fly with self level turn on. It's too artificial looking and robotic to produce a proper scale experience. You would however setup the heli output settings for scale type flying - nothing to do with gyro settings.
@@Rchelicopterfun sounds good thanks for the answer. I'll contact you through the website in the future not a problem, just getting more into the hobby, so alot more questions will arise in the near future! Love your detailed explanations regarding this topic. Thanks for now
What is a good gyro setting for a beginner? Also what setting do I go into to stop my heli from slamming into the ground when I get into trouble and have to throttle down? Trying to learn on my XK 123...had to order another one lol a few hard landings on my roof 🤣
The RTF version's included XK K6 radio is basic, but it certainly works and most importantly, it's computerized so you can properly setup the heli. I do go over the XK K6 TX in more detail in my XK K123 review on my website: www.rchelicopterfun.com/xk-k123.html
What the heck does "tail rotor blowout" mean. I've heard it mentioned a bunch but I'm not sure what it means. Does the tail motor actually die or what?
Tail blow out occurs when the tail rotor can't produce enough thrust to counter main rotor reactive torque. Usually occurs during a torque spike (ie. collective pitch pumping or fast head speed change). My page on RC heli tail rotor operation & theory covers this in detail: www.rchelicopterfun.com/rc-helicopter-rudder.html
I have entire flight school section on my website with both video and written lesson plans. From ground hover to circuits, to nose in. www.rchelicopterfun.com/how-to-fly-rc-helicopters.html
I personally feel there are better micros to learn collective pitch flying skills on. Scale helicopters like this one are more fragile, they cost more, they weigh more, and with the multi-bladed head, are less efficient (shorter flight times). If you want to learn collective pitch flying skills on a lower cost micro heli, my personal recommendation would be one of XK's pod and boom models such as the XK K100 or XK K110. This page on my website might also help you: www.rchelicopterfun.com/best-rc-helicopter.html
Hi i have been using 3.7v 700mah lipos for the past 8 months for my k124. But recently the only replacement i found is 3.7v 800mah. Do u think the heli can take it? If it can, any changes i can expect in terms of performance and durability?
It's pretty much a subjective decision since they are both so close. The 124 does fly marginally better I find due to less TRTT induced lean and tail hold is marginally better when flown at the power limit. On the other hand, I still enjoy my time flying the 123 a wee bit more simply because I like the full size AS350 plus the 123's bright color scheme is easier to see. Again, subjective points, but it may just come down to the one you like the looks of better. May just have to get both ;-)
Hi John, i have a 14 months old K124 and it has flown greatly over the period. However recently i had few crashes due to tail motor blow out. Swapped to a new tail motor, and with this one, after i spool up about half throttle just before took off, the tail motor kind of whined for a split second and kicked the tail to the left (heli nose turned to the right) and both motors will stop spinning. If i cut down the throttle then spool again, the rotors will start spinning again. What could be the problem? Is tail motor or faulty PCB board? Thanks in advance, appreciate your help.
Sorry - no idea without testing the motor outputs in person on an O-scope. I would start with another new tail motor and if it does the same thing, then a new board next.
@@Rchelicopterfun ahh okay, i was also thinking the same thing. Because this new replacement tail motor is not a whole assembly from K124’s parts list, but rather just a universal motor with the same size (which can also replace K110 tail and K100 main). Will try another motor and if it happens, then PCB change. Thanks for the input, mate!
Why on earth would anyone want such a useless feature in a small scale micro CP heli? That is not what it's designed for, not to mention the addition of even more unnecessary weight and power consumption to an already heavy 1S powered micro scale CP heli. Stick with a basic & simple to fly micro quad-copter if you want an aerial imaging device.
No range issues, but I only use the multi-module for the smaller BNF stuff I have so have never tested it much past 600 feet or so. I use the internal FrSky RF on my larger helicopters. I did update the firmware in the iRange X module shortly after I got it, but haven't touched it since (it's currently running version 1.2.1.64).
124 is bigger and brighter so it's easier to see and for me that is a factor for any little micro heli. Canopy fitment is also easier on the 124 so it would be my personal pick over the two. The 124 however does fly a bit better. It depends on what criteria you deem more important.
Hi! I recently bought an xk k124 helicopter rtf and I can't get it to enter in 6g calibration mode/ 6g flight debugging mode(as per manual) ?! When I pull both sticks of the transmitter all the way to the bottom position and hold them there, as I read in the manual and as I watched in online videos, nothing happens. I tried all the settings I could think of : in 6g, 3g, even 3d mode; with dual rates high and low, with different values for the dual rates - under, to 100% and above, with different throttle curbs,I have factory reset the transmitter, I have rebind the heli to the transmitter etc, nothing happens. Can you get yours to enter 6g calibration mode? Thank you!
To be honest, I haven't tried to calibrate the accelerometers (6G mode) on this K124 yet as it was perfect out of the box. I did however have to calibrate them on my K123. I cover the process in my K123 review on my website: www.rchelicopterfun.com/xk-k123.html As I mention in that review on the 6g calibration process, the one deviation from what's listed in the manual where you hold both throttle and elevator sick full low, is you have to have the auto level (6G) mode toggle turned on, not off. I also had to ensure my dual rate toggle was turned off so there was enough of a low stick elevator output to activate the calibration. It sounds like you have tried all that as well with no success. I'll try the 6g calibration process with my K124 and if it's not working, I'll try to do a video on the problem and a fix if I can figure it out.
I just uploaded a video showing how mine also won't go into 6G calibration mode. ua-cam.com/video/ZuTbwYgkm40/v-deo.html I was hoping a missing cap on the board might be the culprit but it wasn't. Perhaps others will leave some useful comments as well.
As I say in the video - it uses Futaba's S-FHSS protocol (the digital language the TX & RX speak to each other with). If the 2.4 GHz TX you have has at minimum 6 channels, is computerized, supports heli programming (pitch and throttle curves), and is using S-FHSS protocol, then it will work. If it doesn't have all that, it wont.
some thoughts. the comment about visibility is Significant. i had a heli with a red canopy. but i'm a bit colorblind. so i was always losing orientation. a small heli, especially, should be Bright. yellow/chartreuse/white. for the sake of color-blind pilots, red should Not be used. there is a continuing issue with all cp helis. the head speeds are Way too high. until that changes, i will stay with fp helis. certain fbl cp or fp helis have Too much mass in the main rotor blades. the result is a Wonky, top-heavy dom. distribution of mass. cheers
What's the rest of the story? What did you find wrong with it? Faulty BEC? Overcharged battery? Seized swashplate? Seized blade grips? Over-traveling the servos?
@@Rchelicopterfun I believe it was over traveling of the servos. I bought some replacement servos and before I put the linkages on the swashplate I noticed the travel rate would change from what seemed normal to extreme
No idea. As I state and show in the video, all of XK's helicopter use Futaba's SFHSS protocol (Futaba transmitter ready - FTR). I'm not at all familiar with any FlySky TX so no idea if it has the ability to use a SFHSS RF module or not.

Been flying collective pitch RC helicopters for over 30 years now, instructing for over 25 of them.
Are these significantly harder to fly then say a drone because this fella is making it look very easy.
Yes they are. Here's a page on my website that explains why collective pitch helicopter are harder: www.rchelicopterfun.com/are-rc-helicopters-hard-to-fly.html

Six of one, half a dozen of the other. They both have pros and cons as outlined in both video reviews I did on them. K124 flies a little bit better (anecdotal) and looks a little better (subjective), but it's more fragile (fact) and harder to see (fact).
thank you it has helped me a lot 👍
Beautiful toy.
Thanks John for this review on this one and the XK K123. I have both using the XK-6 tx that comes with them. Just wondering if one came with yours if you would do a super smooth scale flying tx -set up using the XK-6 tx. If not, I'll do some youtube searching to find one. Thanks again :)
I received the BNF (FTR) versions of both the K123 & 124, so no K6 radio. With that said, radio setup is radio setup. The same values I talk about in the video can be used on any radio (with the note that OpenTX like Spektrum & JR uses positive expo to shallow out mid stick output whereas Futaba and the K6 need negative expo. I state the collective ranges I use in my 3 flight modes so you would simply alter your pitch curves in your K6 to achieve similar collective ranges (about -2 to about +9 for these micro scalers is what I personally like).
D/R is largely personal preference just as I mention in my setup & ebook for collective pitch RC helicopters : www.rchelicopterfun.com/rc-helicopter-tips.html
Smooth scale flying style as you likely know is also largely up to the individual flying to pull off. I've been flying scale RC helis for over 20 years now and it does take practice to mimic full size heli behavior - more so on these little light weight micros over larger 600-800 size machines where mass & inertia are your friends.
@@Rchelicopterfun Ok John, time for me to study up and maybe consider getting you ebook. I did get your beginning book on the SR-120 a few years back. I probably need to read that again....I'm retired now so I'm looking forward to spending more time doing this. Thanks much. :)
Mine melted with all original battery. Rtf version. On 1st day in 5 minutes. It was too hot to touch for 15 minutes
Great review. Have you tried doing an autorotation with this heli?
You can't auto a micro CP. About the smallest CP heli that can be successfully auto'ed is a 250 and it's bloody hard to pull off.
Hi John, been binge watching your videos and might even buy your books as the videos have helped me alot so far! One thing I don't quite understand in opentx tho is, how can I setup the gyro to about 30-40% output for more of a scale like flying, but still have all the control over the heli myself? If its at +/- 100 doesn't that either fully activate/disable gyro? I don't want it to be totally aggressive.
Best to contact me through my website for setup specific questions like this. The very short answer however is channel 5 output simply turns self level help on or off. You are not disabling normal gyro operation, only the accelerometer operation (accelerometer sensors are what enable self level). There is no gyro gain adjustability. If you want a scale behaving heli, you would never fly with self level turn on. It's too artificial looking and robotic to produce a proper scale experience. You would however setup the heli output settings for scale type flying - nothing to do with gyro settings.
@@Rchelicopterfun sounds good thanks for the answer. I'll contact you through the website in the future not a problem, just getting more into the hobby, so alot more questions will arise in the near future! Love your detailed explanations regarding this topic. Thanks for now
nice review, thanks 👍👍🚁🚁
One good thing there's no bars on the main rotor its a single rotor helicopter I don't like like ones with bars on the propellers
Amazing
What is a good gyro setting for a beginner? Also what setting do I go into to stop my heli from slamming into the ground when I get into trouble and have to throttle down? Trying to learn on my XK 123...had to order another one lol a few hard landings on my roof 🤣
All covered in detail in my Setup & Tips for Collective Pitch RC Helicopters eBook: www.rchelicopterfun.com/rc-helicopter-tips.html
Interesting.
What RC Controller are you using in this video? Best regards, Chris
I show and say @ 1:15.
Nice heli. Is the included transmitter any good?
The RTF version's included XK K6 radio is basic, but it certainly works and most importantly, it's computerized so you can properly setup the heli. I do go over the XK K6 TX in more detail in my XK K123 review on my website: www.rchelicopterfun.com/xk-k123.html
What the heck does "tail rotor blowout" mean. I've heard it mentioned a bunch but I'm not sure what it means. Does the tail motor actually die or what?
Tail blow out occurs when the tail rotor can't produce enough thrust to counter main rotor reactive torque. Usually occurs during a torque spike (ie. collective pitch pumping or fast head speed change). My page on RC heli tail rotor operation & theory covers this in detail: www.rchelicopterfun.com/rc-helicopter-rudder.html
Do you have a video on how to hover?
I have entire flight school section on my website with both video and written lesson plans. From ground hover to circuits, to nose in. www.rchelicopterfun.com/how-to-fly-rc-helicopters.html
Excellent review mind made up now😂👍
Glad you enjoyed it
Nice review, would you recommend getting this model to begin with helicopter?
I personally feel there are better micros to learn collective pitch flying skills on. Scale helicopters like this one are more fragile, they cost more, they weigh more, and with the multi-bladed head, are less efficient (shorter flight times). If you want to learn collective pitch flying skills on a lower cost micro heli, my personal recommendation would be one of XK's pod and boom models such as the XK K100 or XK K110. This page on my website might also help you: www.rchelicopterfun.com/best-rc-helicopter.html
@@Rchelicopterfun thank you i will check it
Sir I am from Pakistan how I bought this
Hi i have been using 3.7v 700mah lipos for the past 8 months for my k124. But recently the only replacement i found is 3.7v 800mah.
Do u think the heli can take it? If it can, any changes i can expect in terms of performance and durability?
Check the size... That's the go / no-go determining factor.
John Salt the size is similar. All right noted on that. Thanks mate!
How much??
Which one is better k124 or k123
It's pretty much a subjective decision since they are both so close. The 124 does fly marginally better I find due to less TRTT induced lean and tail hold is marginally better when flown at the power limit. On the other hand, I still enjoy my time flying the 123 a wee bit more simply because I like the full size AS350 plus the 123's bright color scheme is easier to see. Again, subjective points, but it may just come down to the one you like the looks of better. May just have to get both ;-)
John Salt so what would you recommend because I really can’t choose!😂
Hi John, i have a 14 months old K124 and it has flown greatly over the period.
However recently i had few crashes due to tail motor blow out.
Swapped to a new tail motor, and with this one, after i spool up about half throttle just before took off, the tail motor kind of whined for a split second and kicked the tail to the left (heli nose turned to the right) and both motors will stop spinning.
If i cut down the throttle then spool again, the rotors will start spinning again.
What could be the problem? Is tail motor or faulty PCB board?
Thanks in advance, appreciate your help.
Sorry - no idea without testing the motor outputs in person on an O-scope. I would start with another new tail motor and if it does the same thing, then a new board next.
@@Rchelicopterfun ahh okay, i was also thinking the same thing. Because this new replacement tail motor is not a whole assembly from K124’s parts list, but rather just a universal motor with the same size (which can also replace K110 tail and K100 main).
Will try another motor and if it happens, then PCB change. Thanks for the input, mate!
A shame they never made a DSMX version. I would have been all over it.
Hope that rc have micro camera
Why on earth would anyone want such a useless feature in a small scale micro CP heli? That is not what it's designed for, not to mention the addition of even more unnecessary weight and power consumption to an already heavy 1S powered micro scale CP heli. Stick with a basic & simple to fly micro quad-copter if you want an aerial imaging device.
How do you find the range on the irx4. Have you done any firmware upgrades?
No range issues, but I only use the multi-module for the smaller BNF stuff I have so have never tested it much past 600 feet or so. I use the internal FrSky RF on my larger helicopters. I did update the firmware in the iRange X module shortly after I got it, but haven't touched it since (it's currently running version 1.2.1.64).
123 vs 124 which did u prefer?
124 is bigger and brighter so it's easier to see and for me that is a factor for any little micro heli. Canopy fitment is also easier on the 124 so it would be my personal pick over the two. The 124 however does fly a bit better. It depends on what criteria you deem more important.
@@Rchelicopterfun well imagine xk 124 with 123 canopy but 5 blades😍😍😍
@@Rchelicopterfun Yes I agree 👍K124 is more stable than K123 it is because K124 have 4 Blades. That's why I chose K124
How can i have that helicopter
Hi! I recently bought an xk k124 helicopter rtf and I can't get it to enter in 6g calibration mode/ 6g flight debugging mode(as per manual) ?! When I pull both sticks of the transmitter all the way to the bottom position and hold them there, as I read in the manual and as I watched in online videos, nothing happens. I tried all the settings I could think of : in 6g, 3g, even 3d mode; with dual rates high and low, with different values for the dual rates - under, to 100% and above, with different throttle curbs,I have factory reset the transmitter, I have rebind the heli to the transmitter etc, nothing happens.
Can you get yours to enter 6g calibration mode?
Thank you!
To be honest, I haven't tried to calibrate the accelerometers (6G mode) on this K124 yet as it was perfect out of the box. I did however have to calibrate them on my K123. I cover the process in my K123 review on my website: www.rchelicopterfun.com/xk-k123.html
As I mention in that review on the 6g calibration process, the one deviation from what's listed in the manual where you hold both throttle and elevator sick full low, is you have to have the auto level (6G) mode toggle turned on, not off. I also had to ensure my dual rate toggle was turned off so there was enough of a low stick elevator output to activate the calibration. It sounds like you have tried all that as well with no success.
I'll try the 6g calibration process with my K124 and if it's not working, I'll try to do a video on the problem and a fix if I can figure it out.
I just uploaded a video showing how mine also won't go into 6G calibration mode.

I was hoping a missing cap on the board might be the culprit but it wasn't. Perhaps others will leave some useful comments as well.
@John Salt What kind of your controller you used in this video? I really like it!
I show & say at 1:15.
@@Rchelicopterfun I saw it. Thank you.
hi price for this
I have several 2.4 gigahertz transmitters that came with other helicopters. Wondering if just helicopter is also 2.4 gigahertz on the bind and fly.
As I say in the video - it uses Futaba's S-FHSS protocol (the digital language the TX & RX speak to each other with). If the 2.4 GHz TX you have has at minimum 6 channels, is computerized, supports heli programming (pitch and throttle curves), and is using S-FHSS protocol, then it will work. If it doesn't have all that, it wont.
@@Rchelicopterfun, Thank You.

May i know whats the setting in horus for this heli?
I go over setup starting at time index 20:25
some thoughts. the comment about visibility is Significant. i had a heli with a red canopy. but i'm a bit colorblind. so i was always losing orientation. a small heli, especially, should be Bright. yellow/chartreuse/white. for the sake of color-blind pilots, red should Not be used. there is a continuing issue with all cp helis. the head speeds are Way too high.
until that changes, i will stay with fp helis. certain fbl cp or fp helis have Too much mass in the main rotor blades. the result is a Wonky, top-heavy dom. distribution of mass. cheers
hi i'm interested more on your radio. what is it? thanks!

What's the price of this
Links in description to various packages.
I bought one last year and the servos burned out on the first start up. Was very bummed about that.
What's the rest of the story? What did you find wrong with it? Faulty BEC? Overcharged battery? Seized swashplate? Seized blade grips? Over-traveling the servos?
@@Rchelicopterfun I believe it was over traveling of the servos. I bought some replacement servos and before I put the linkages on the swashplate I noticed the travel rate would change from what seemed normal to extreme
Might have been a faulty board. So I'm gonna order a new heli sometime. It was super discouraging at the time.
Good to know.
How to bind flysky i6x ??? 😢
No idea. As I state and show in the video, all of XK's helicopter use Futaba's SFHSS protocol (Futaba transmitter ready - FTR). I'm not at all familiar with any FlySky TX so no idea if it has the ability to use a SFHSS RF module or not.
What is price this
Prices vary between $100 & $150 USD depending on which version & how many battery packs. I have links in the description for current pricing.
