Josh, could you do a video about the opposite end of the spectrum: how to build and tune for the most efficient quad possible? I'd like to see what you would choose for a super long flight 5 in and 7 in build.
Awe yeah!!! Running the old beast. Glad the ESC held up. Some sick stuff and thank you for the shout out JB! Much love big dawg!
I have a Skystars KM45 esc and as far as i can tell this is one of the durable esc i have. I mounted it in my race rig and after several (hard) crashes I count more burnt motor than esc damage. I bought 2 more of their esc hoping are as durable as the first one.
5:38 - Instead of USB power for the GPS, get a ViFly GPS Mate. It functions as a powered buzzer and powers the GPS before the fix and between LIPOs. It's easier and more functional than a USB power bank.
esc-configurator works with all chromium based browsers, so it will also work with Edge on Windows. Chrome, Chromium, Vivaldi, Edge. NOT Brave though...
Id argue that the props flattening out was making it easier on the ESC since they were not biting the air as much on the top end there. Retry with stiffer props 😂
funny, my first idea was, that you would need steeper props for these speeds
@@ersetzbar. Haha I don't think that same lipo would survive it. The poor thing was crying. Might need a beefier battery for that!

I like this kind of content a lot. It's unrelated to FPV "current events", new releases, blah blah blah. Just good old experimentation and crazy fun.
Bardwell always out here with all the info I need when I get new drone stuff I don't completely understand. Another great video
that is insane, dude! awesome vid!
cheers, stay safe and have fun!
Cool concept. I like these types of torture tests.
Watched this whole thing! WOW brotha! You’ve just motivated me to pull mine out of mothball. So sick! 🔥🔥🦄🦄🦄🦄🦄👌👌👌
My first mini quad was a 2400kv emax hawk pro. I ran 6s on it for like half a year. No issues with it at all. Was super impressed when I learned that I wasn’t supposed to do that 😬.
LOL, one of the things that saves you is its not a static load. If you did it on the ground without a dynamic change in load you might have had some toasted components..lol Good times. I bet it was fast.
LOL
We did this a couple years ago. I actually built the same quad after your video. The Luminier F7 and Tmotor ESC with 2800kv motors on 6s. Still have the parts from it.
Also depends upon the weight of the quad compared to what it was before with the pid's, especially with high power to weight quads, the pid's can really vary a lot, normally an amount of TPA such as 70% at 1700 can be applied to smooth out that wobbling caused by the pids at top end of throttle ;)
Yes! More high speed/power content please. I've probably watched your Ryan Harrell interview ten times!
Thank you JB.
I did learn something today.
my favorite stack was worried about smaller esc but so far so good have a few and love them light weight powerful super dependable
i always learn something with your videos. ty
Been buying these ESCs for a while, they are good, and they were cheap. I think I got my first one (45A) for ~$28. Those days are long gone.
Fantastic flying, Joshua! 😃
Pretty interesting stack indeed!
About the Gemfan props, the force is strong in their family. They didn't break even after crashing. 😬
Anyway, stay safe there with your family! 🖖😊
Nahhh I'm not a fan of the durability of the F4 props. The bend and crease really easily and don't flex.
Wait what I can build a flying fireball 🤣🤣 love the channel bro looking forward to more juicy info
Amazing review
Sorry for advertising but ive learnt everything from you JB
The ONLY way I found mine to go that fast with your exact set up was using carbon by-blades, other wise the tri blades set up just drew too many amps causing the quad to flip out. The settings I had to work with was not so much pids or filters but the setting in the esc, ramp up and such but in the end I was successful, the video is on my channel. Hope that helps.
Carbon blades are insane. I only had one pair back in the day but what a difference in characteristics.
Well! That was fun!!
I put that fc in my cart 2 weeks ago. Looks good. Don't really know skystars though.
I've been very happy with my Skystars esc and fc....
I use there "slim" individuals on planes seem fine. Skystar also has targets for inav and some for ardupilot
I love my F722!
I was telling you about these esc's over a year ago!!
Can you show a setup on this board? My elrs stops binding when i solder in the caddx vista
Lmao the reaction to it freaking out was mint JB 😂😂 uhhh that’s gonna be a no 😂
I’ve ran this fc on a couple high power builds and it’s a tank, also stupid easy to solder to.
Skystar FCs And ESC will maybe Take over mambas place in The Future ...
@joshuabardwell thats weird I had 2208s 2450kv on 6s....and with a good esc and FC I didn't even have to tune it for it to fly decently.... it was a freestyle frame... good esc was fine but it did ignite a cheap tmotor esc doing a split s....
This oughta be good. *grabs popcorn*
I like skystars fc and esc and the prices are awesome
your reaction @15:50 was hilarious. Bzrrrrrrrrt. Bzrrrrrrrrrrrrt. Thud.
Hi! Awesome video
Can you run a 50V 470uF capacitor on this kind of setup? I can’t seem to fit the 50V 1000uF on 😢
My Diatone Mamba blew when i tried the 66 percent motor cut when i threw a 6s on it. FC fried for some reason. Had the correct capacitor and everything. Rest in peace
I just got mine gonna use it on a 3.5 flyfish!
Extra likes 👍 for the sound effects @ 10:58
I really wish my first product with skywtar wasn't a total bunk. Didn't even have the motors wired up. Just made sure everything was good with the esc to fc. With a smoke stopper. And an esc on the underside of the ESC just blew up
so for video on all the time you have to bridge VON pad or just leave it as is ?
Yay that answers an unsolved mystery of mine. My quad freaked out upon takeoff just like that, but not on betaflight 3.5, only when i updated to 4.3. I guess my quad was too powerful for betaflight 4.3 defaults. On that note, I have never gotten 4.3 to fly as well as 3.5, which is kind of a bummer. I tried downgrading but 3.5 but it isnt in the software list anymore. I could probably find it on the web somewhere but its just that extra bit of hassle. I kind of wish they just left old versions in the configurator longer, but i know thats a hassle for them because the gui doesnt work with versions that old.
I don't know if you guys ever had the chance to fly the Diatone R349 but it was telekinetic. It was about 35mph down from this quad but the absolute power to weight ratio made it directly connected to your wishes.. It also pulled down 90+ amps on a three inch...lol
Still have and fly mine, it's a beast!!
really wanted to see the props explode but no damage .. thanks J
Lmao Joshua face when quad took off 😁😁
Just realized I've done my first 4s build and this is totally possible. 2750kv on mine and as I predicted from your 8s videos these 4s motors are already hot on the right voltage and the blackbox is good😬. 30x30 BL32 and rvs creamer frame.
Hey, does she get from point A to point B real fast??
Hello,
I got the F405 fc with the k050 all in one esc stack.
I can't seem to find the manual for this fc or any skystars fc. Do you know where i could get the manual or more info about the setup
(This is my first build)
I have a problem: the motors when idling vibrate and make a rough sound that fades as speed increases (both with and without propellers mounted).
I bought mini F722 HD Pro AM32 ESC Stack 2022 version
and I'm using it with 2806.5 1300kv
I'm using Betaflight 4.4 and checked that all 4 motors spin in the correct direction (if I use Betaflight for spin the motors they suond smooth)
Can someone help me please?
Think that new speedybee v3 stack could handle a 4s motors on 6s?
I laughed so hard at those squeals lol😅
I have the same problem on "classic" motor in 1800kv in 6S...
I think that we have to decrease startup power like as rampup power....
haha that scream 😂
I have my quad with the Mamba f405 Stack with 2400kv Motors and ran it on 6s Not often just for fun it still works but i killed 3 6s 1550 lipos in the matter of like 5 flights😂
Just fitted some new Pacer III v2 2306 1950kv motors on my previously 2306 2450kv hypetrain rig and my f7 Mamba 50a stack is freaking out am getting mid throttle flyaway at take-off. What would I do to fix this I've reset everything to stock latest firmware target and esc updated to latest firmware but still the mid throttle madness continues to plague me. Any help would be muchly appreciated 🙏
Hey there JB,first of all love to watch ur vids.Actually m new to this hobbie,and i need a suggestion,m building a quadcopter and the issue is i got mamba mk3 stack which has only 5v bec out and the Vtx i got is an Akk Raceranger which requires 1600mw power,so the question is should i got for an individual 12v BEC or a Normal 2/3A 9-12v stepdown voltage regulator?Thnkx
Im running the mamba f722 mini mk3 and akk fx2 ultimate mini, i just use the vbat pad from the fc to run the vtx. Not a single problem to this day besides noise as i havent installed a capacitor on the esc. If u just add a capacitor to the xt60 or the esc power pad i bet it would eliminate most of the noise.
@@RD5500 Thnkx for the info man🙌 .Yes m already using capacitor,soldered directly to the XT60 connector.
The real question for me is about the propellers. What type/model of props can handle that speed efficiently
Can it be used with 1404 4500kv motor???
The GPS voltage should be selectable 3v3 | 5v
Me, spamming the FAA Drone Zone waiver applications with all sorts of requests to fly fast, or to fly 20 minutes after twilight...
(Spoiler alert, it's actually pretty easy to do)
What sound was causing him to say there was prop deflection?
I've got a old but flawless 6 inch moka frame with brother hobby r5 2207 2700kv with a old school Bardwell yep Bardwell flight controller that 4in1 dal rc motor esc that I've clocked at 106 mph with 5 inch 5x4.3x3 hq v1s props it's very snappy hanging on my wall for about 2 or 3 years now just begging me to play with it
So I have bluejay on... and I am getting EXACTLY what you described about the variable PWM frequency. Mid throttle only oscillations! Can you not turn this setting off without re flashing the escs? I don't even see that option on there.
You can only change the Bluejay PWM frequency by flashing the ESC.
I Bet you'll catch BIG FOOT Now 💯
Affiliate link, Joshua? I don’t see it? Picked up a couple of the full size F7 HD stacks a while back when they were cheap. I’ve had good luck with the one I put on a basher quad. 50ish packs in with no issues. Average sessions, nothing extreme. Not a lot but it’s a sample.
Geez how did that not get saved! I've added it now thanks for pointing it out.
Regarding 21:55 ... if you even thinking about doing it, go for 163.5+ mph and claim a Genius World Record.
A good number to aim for would be 186+ mph .. .300+ km/h. Can then brag you're a speed demon and broke 300 baby! ♥🏁💨
Maybe there even an indoor sport/track stadium that would think it fun to claim to be home base to a GWR.
There is a 360+kph video on YT. You'd need to go faster.
Maybe try a 20x20 ESC that has full sized MOSFETs? The Foxeer Reaper 60 and the Reaper 60 Slim are two that come to mind.
ESCs that have the small MOSFETs usually can't hold up for long when being put under a lot of abuse.
Yes! I agree. This one won't be as durable as the Reaper.
This has full-size mosfets
I asked JB on his livestream about skystar stacks several times due to them being so cheap.I have my answer if its on a 160mph quad 👍
They got a bit of a bad rep early on. They've come an incredibly long way since. The F7s and H7s are the only FCs I'll buy now!
Just curious what variant of the Skystars ESC was used for this experiment (or does AM32 only come in the one 55A size)? My "build" (BNF) with the KO45a ESC and 1700kv motors turned into a fireball after a relatively minor crash (other builds survived worse crashes)
It's the 55a one.
i built a switchback hd with 2500kv f80s and a rushfpv 60amp extreme id say its right around that 160-170 mark
Awesome 💯 How much to make me one?
It has a BMI 270 gyro, so of course you had to get different (or stronger) filtering options than with the old 30x30 stack wich had the mpu 6000, I guess.
I've been comparing mpu6000 and bmi 270 for a while now. It's pretty much the same. I even have a mpu 6000 fc which actually needs more filtering than my other parts.
That shouldn't be true in BF 4.3. It changes the internal hardware low pass in the BMI gyro to be similar to the ICM and MPU gyros.
What the function on gps sda scl?
Compass.
Have used sky star in the past and always seem to catch on fire…in their defense could be user error!!
18:55 You need to adjust the tracking on your VCR.
"... and you can definitely NOT see that happen" bwahaha
what motors did u use
T-motor F40.
Does an esc put the full battery current into the motor and adjust the frequency or does it adjust current and maintain a fixed frequency or both?
It adjusts the frequency of the PWM signal. The PWM signal oscillates between full voltage and zero.
@@JoshuaBardwell thank you
Of all the places in the world to fly,Bardwell house got be one lol
What all ESCs are capable of running higher kv motors like this? Can someone name off a few? Like what is the best to do this?
I like the spedix gs40 and ls40 20x20s. Full size fets , 6s and reasonably priced. Defiance RC has them.👍
All of Foxeer big FET ESCs will do 40V 100A easy from experience.
I have heard good about Holybro metal capped FET ESCs, but haven’t personally stressed them.
Im thinking of using this stack in a lightswitch racing build. do you think it is worth it/Reliable enough?
@Joshua Bardwell
I only tested one so I can't for sure say how durable it is. It held up to my testing though.
Today I learned...
Sensored motors would be for FOC, although nowadays you can use estimators without a hitch. Just at 0 rpm you need to jog the motor cus the controller doesn't know the position.
Sensored motors are not just for FOC. They are often used in ground vehicles where you need torque at low RPM.
@@JoshuaBardwell if it’s not a servo, you can’t get 100 torque a low rpm with synchronous motors. An inherent trait.
Unless you use a vector control based system you have no finite control over torque as it is still coupled to flux thus speed. Moreover the motor is unstable till you reach the steady state rpm. I went a bit off topic but that’s why I’d love to see foc on drones. Part of my degree was control theory and motor control. When I hear PID I shudder when I hear pid, as the running gag is pid is the poor man’s choice and is never the solution (pid is only optimal with 0 delay, which isn’t possible)
in our case sensorless is absolutely fine, if an arduino can do it… anyhow thanks for your insight, love your content btw
Oh, I so "not want to see that happen"!
What is an ESC?
But if c rating higher on 6s will fly faster
Can the faa do anything if your on your own land? I'm Aussie we don't have dumb laws yet
You are not on your land you are in their air space. There for yes.
We have worse laws in Australia...FPV is basically illegal here.
@@BengalCatChilli Like in The whole EU 😅
DAMN, thats more than 250 kmh. While my irc goes 100 kmh😂😂
Different firmware, different props, can you really say the new FC is flying worse when you are not running the same config?
Interesting video, have been running AM32 and have blown a couple of blheli32 ESCs recently but the Skystars AM32 are holding up well.
lmao i didnt know akon made great escs and music\
shiet we should make an esc startup song with akon
power ¶ ; - )
so fast
"Trilly oscillations" my BF experience in a nutshell
LOL😆
I used to fly 2750kv on 5s 🤷🏼
Bardwell you never tried the old pids and filters. You only tweaked the defaults once and didn't play with esc settings after setting this up. Dont think it's fair at all to say the fc is noisier without any attempts to validate it.
For sure. I wasn't interested in doing a big in-depth comparison between the two. It was just my impression. The old PIDs and filters were from BF 4.2 anyway, so directly copying them I'm not sure would be fair. I can say, however, that the old FC and ESC could at least hover on default 4.2 PIDs and filters, but 4.3 default PIDs are more aggressive, so I'm not sure that's fair either.
@@JoshuaBardwell fair, didnt realize the last batch could fly on 4.2 defaults. I would be interested to see if you could tune out the bad behaviours and get it working really well. Tuning aircraft like that has always been more entertaining than typical aircraft.
@Russell Phelan even with the sliders turned down ridiculously low, this quad still had some noise-related issues and wasn't flying perfectly whereas the other quad had higher PIDs, less filtering, and flew better. So which direction is the tuning going to go? We're going to turn the PIDs and filters down even further and it's going to fly worse? That's what I based my opinion on.
To do a fair comparison, I would have to upgrade the old FC to BF 4.3, then do a detailed PID tune on each FC, and etc. That might make a good video, but it's not the video I was making at this time. So you get an off the cuff comment at the very end of the video, with my general impression, and you can take it for whatever you think it's worth.
This would be so much better if i knew what pids and filters were... 😂
