⮟⮟⮟OPEN DESCRIPTION FOR MORE INFO⮟⮟⮟
I have to tell you guys... the Phoenix V2 was impressive... but the Phoenix 2400 is absolutely outstanding! It is more or less the same as the V2, but bigger... and that does have some advantages - I can use a much larger battery, while still keeping CG, and since the motor doesn't draw much more amps, flight times are much longer, which now makes it even better for FPV... especially with that tail mounted camera! I am going to be pushing this one to its limits for sure, including an even bigger battery! Will also add the antenna tracker module, so I could really send it out far and high!

I find your reviews most informative and fun. Definetly buying it!
Thank you! :)
As always, great videos to watch, I like the honesty and plenty of information.
Thank you mate, appreciate it!
I love your indepth reviews, No bullshit, just good experienced opinions/facts, thanks for the great review on this Bird as I have 2 Phoenix 1600's (1 still in her box) and it is a great glider/sloper and very forgiving..
I have been looking at the V2 2000,, but after viewing this I'm trending more to the 759-3 2400. Looks so stable!!!
Great job, thanks again.
Thank you! Yes, indeed it is more stable and I do prefer it to be honest! :)
Awesome review!! I love it!
Tail-cam is a Very nice touch!
Thanks mate, yeah, I love the tail cam as well, gives a unique view of the plane!
as always the best review!
Thank you! Much appreciated!
Lovely to fly, 15 minutes of flight from a 3S 2200 battery, still needed a bit of nose weight, circa 15 gms.
Excellent video, Well done !!
Thank you! :)
A really great video to watch
Thank you!
Hey, nice evolution since Eachine Pioneer E350. Best hopes for this new year !
Thank you! To you too!
Thinking of getting this model. Ive never flown a "glider". Looks like i won't be disappointed
Yeah, the Phoenix is awesome, and this one even more so! I like it a lot!
Another great video! Absolutely loved that low slow flying. It has me so tempted to pull the trigger on this but honestly, both my R2k and R2.4k are still sitting in their boxes. In fact, now that I think about it, I still have a Phoenix2k v1 still in the box from back in the day! I buy quite a bit on BG and the one take away I have from this video is that moving forward I'm going to make it a point to use your affiliate links! Looking forward to seeing you hit 10K subscribers.
Thank you! Really appreciate it! :) Love this plane, just flew it again and it is absolutely outstanding with the LiIon battery!
Very nice work.
Thank you! :)
Great video. Incredible air-to-air video from the Phantom. Can't wait to see a proper long range/high altitude flight with this huge bird.
Thanks! I am flying it today, but sadly the weather doesn't allow high altitude... :( there are some clouds but it is too windy up there!
Awesome review!!!
Thank you! :)
Just flew mine today. Went from 100m to 230m in a tiny thermal as the lift was terrible however I managed to find some with my frsky vario. Now I am remembering how to thermal I am really enjoying it. One tip - set some full span camber on a switch. It really responds to 20 and 40 (in the Taranis) of camber on the three position switch. I have flaps and ailerons on 4 channels so I get full span camber. Put on about 4deg camber and the plane will slow up an really float around looking for lift.
Good suggestion mate, thanks! :)
I bought one and it is fantastic, it is now my go to glider, I was surprised how it handles strong wind, thanks for another great review
Glad you like it too! :)
Quality video as always :)
Thank you!
Great video
Thank you! :)
Well done!
Thank you! :)
Just found your channel and your reviews are absolutely great, to the point and very informative, thanks for this great video. I am new to fpv and plan to start my first plane fpv soon
Thank you! I am happy these videos are of help to you! Good luck!
@@ArxangelRC Thanks, have you checked out DJI HD Fpv? For someone like you who does so much airplane fpv it would be amazing.
Yes, it would! Sadly... outside of my budget now... and with the whole world stopping most purchasing... my income has greatly been reduced... soooooo... no prospects to get one anytime soon!
@@ArxangelRC Same here man, we freelancers are in the same boat i guess, watching some of those hd fpv videos got me really interested, but income is on hold right now so cannot even think about making such purchase, i have a lot of mix rc planes though and i have been flying and building for 4 years now. I hope we all can go back to our normal lives soon as this pandemic is over, sending you positive vibes from India! . cheers
@@nakul3424 Right back at you mate! I hope for the same! Best of luck!
Love Volantex.
You and me both!
Thenks
You are welcome!
Well I just impulse purchased one of these (yes I used your link). Everyone seems have nothing but good to say about them.
THANK YOU! :)
Your English is excellent. Well done.
Thank you! :)
@@ArxangelRC удовольствие
Your videos are always so insightful so I bought one and it is a Fantastic glider ! Very nimble for a 2.4 m wingspan. I will use it as my fpv platform. I tried mounting my fpv camera on the back but I find the CG to be tail heavy, and this is on a 12 gram camera similar to your setup, I had to put in a 2600mah 4s to balance it out, but still a little tail heavy. Do you find the factory CG marks to be accurate or are they a bit out ?
Thanks mate, appreciate it! Glad to see my videos are useful! As for the CG, yes, it is correct, you just need more weight up front! My battery is 400 grams, and I still need more weight to balance it properly! Don't be afraid to go with a larger battery!
onto 10k!
Yeah, hopefully soon!
Impressive machine. I'll need a _much_ bigger backpack :)
Hahahaha, yeah! :)
Thanks for the great videos Arxangel, question, on the site it says 3S, will it fly with a 3S 3000mah or does it feel a little on low side on power and stability?
It will fly, no question about it! Stability? The battery hardly determines that, as light the plane is, the easier it will thermal and glide! :)
did you upgrade the prop? I run an 11 from aloft hobby on my radian pro its ballistic
but I just climb and power off of course
Yes, eventually I got a 12" carbon one. Works a treat!
Do you have the servo holders and cam mount stl's available for download? Thanks in advance!
Yes, drop me a line on Facebook and I will send them to you! :)
Hello i have boght this plane and installed inav but plane flying not good is it possible to look at your inav pid and advance settings? :)
Sorry, I am using ArduPlane with this one, not iNav!
Hello. I'd like to get your input if possible. I'm finding my self with a lot of clutter outside (and now added drag) after installing my gps, telemetry, crossfire Rx and vtx. For long range on this platform, how have you arranged your components to avoid all the outside clutter (and added drag)? Are you embedding vtx and Rx in the wings? Maybe keeping gps inside the canopy? What's been your best practice? Thank you in advance for your feedback.
Hey, yes, GPS is in the fuselage, as is the receiver and its antenna! The Vtx is on the outside, but it is the Vtx03, which is very small and with a very small antenna... so it doesn't create much drag!
hello. I want to ask if it's normal?. if my servo motor moves by itself and returns to the middle position when I first connect the battery. or do I need settings in the transmitter
If the servo is away from its center point, when you power it up and it is receiving a valid signal from the receiver/autopilot, it will return to center if the switch/stick associated with it is centered.
Can i have crow mix braking when my ailerons are plugged into a ZHOD KOPILOT LITE but turned off? Current set up is a Voalntex Phoenix V2, Flysky FS-i6x and FS-i6b, plus the Kopilot. what i am thinking is it possible to use the crow mix when the Kopilot is NOT engaged like when coming into landing i turn the Kopilot off so would crow braking then work or not? or would i need a bigger number receiver? as i have a 6 channel that is all used up.
You can't! You need to plug only 1 aileron input into the Kopilot, and it has only 1 aileron output! In order to do that you need to have the ailerons on two separate channels, which can't work with the Kopilot!
I love this plane also. Unfortunately the motor is damaged and I am waiting for the replacement.
That sucks!
makes me want to buy this big plane. I used to fly the original Phoenix2000 7 years ago, and it was not very good compared to a Radian. but 2.5m would make a big difference, esp with a big hatch area
The fuselage is actually plastic! :)
But no ailerons with the radian
Hello guys. Does anybody know of you can fit the bigger wings to the fuselage of the 1.6m or 2m model?
If you are asking whether you can fit the 2400 wings to the 1.6 or 2m one, then NO, it can't! The 2400 wing is bigger in every aspect and will not fit.
Hi, great video. I've been flying drone for three years and I'd like to start a new experience with plane, fpv and long range. Do you think this is a good model to start or could you give me an advice? Thank you
Actually, even though it is on the larger side, this is a great model to start, because it can forgive mistakes, doesn't like to stall, and should give you some good flying times!
hello there...... i want to buy the (Volantax Phoenix V2 759-2 2000m Wingspan EPO Sport Glider RC Airplane KIT) how bean posible the 759-2 pnp have flaps and the 759-2 kit dont have flaps at youre links? this is the same model i think? its mistake at the page of the bangood?
They both have flaps! Don't worry about it! :)
Can you recomend foalding propp and how about pnp servos or better to buy kit version?
PNP servos are mostly for calm weather... I would get some metal geared ones! As for a prop... I am using a 12x8 carbon folding from I got from HobbyKing... links should be in the description of the video!
Do you have the autopilot setup to automatically apply flaps? I think this would be a pretty cool feature to use
I have not used that actually... not sure how I feel about it messing with flaps automatically!
What's the achievable air speed using the motor? Also, do you have an idea about the maximum wind speed it can withstand?
No idea... this is not a speed model, so I have not tested that... but I guess with some motor it could be made a bit quicker... but not going to be easy with those huge wings!
I want it all, except the $ to have FPV. Would like a camera to record a flight video however. Hard as heck to figure out all the stuff you need to buy.
Plane $150
Receiver 30
flight controller $40
Voltage sensor $20
Batteries 50
Battery Charger 20
Tx and Battery $130
Total: $440
plus camera (which one?) and mount? What am I mission to do mission flights and record?
And, what would make it easier to land, level wings, does the flight controller help with that?
I'm an old aerobatic slope glider guy, rip, flip, twist.
Yes, the autopilot would keep wings level for a landing, no worries about that! As for camera... there are a number of options... the smallest in size with the ability to record high quality video are the likes of RunCam Hybrid for instance: www.banggood.com/RunCam-Hybrid-4K-30fps-FOV-145-Degree-HD-Recording-DVR-Dual-Lens-Mini-FPV-Camera-Low-Latency-Single-Board-for-RC-Racing-Drone-p-1564153.html?UA-cam&ArxangelRC&p=6L1818635832201406F2

Great video my friend, did you use phantom for overhead view of volantex?
I believe he mentioned Phantom 3 Pro @ 4:46
Yes, the Phantom 3 Pro was called upon once again! :P
very good comments for me that am old and intend to buy a flying RC model for my grand son 15 years old. I was building balsa models with 2 stroke motors 60 years ago and now, since I am an aeronautic engineer in pension, I'd like to restart with aero-modelling. Do you think it is a good idea to start with this model to learn to fly with RC? Can you advise also on good and not expensive Radio?
Well... the FrSky Q X7 is a good entry level radio with awesome range and a reliable link! There are various receivers for it depending on the purpose! This plane should be OK to learn on... at least for me it is quite docile and can slow down... so I would say it should be a good learning platform... BUT... I would suggest spending at least some time on a simulator for instance... just to get some basic reactions!
Any review and update for volantex Ranger 757-4?
Which one was that again?
Thank you as always for your amazing reviews! I just ordered one as well (using your affiliate link). One question, the specs mention using a 3s lipo. Can 4s be used? I'd hate to buy a 3s battery just for this plane. Thanks in advance and thank you for posting great content!
Thank you!!!!!!!!!!! Yes, you can use 4S even with the stock ESC, the motor can take it, just don't use full throttle too much and for too long, otherwise it has been OK for me!
ArxangelRC Thank you for your response. One last question If you don’t mind. Do you laminate your wings by any chance?
@@AlexanderPerez-oe1gu Have not on this model, but you could! If you plan to use it long term it might be a good idea, will make it more slippery through the air, for minimal weight added... and will also keep the foam in a better condition!
my question and suggestion on next video is , you got so many FPV plane can you tell us , with one is the best one , and best one for beginner ?
Well yes... many... so it depends on best for what purpose! Also, I have a few planes coming for a beginner video... so should have that covered soon enough!
Just received my 2400. Will be adding Arduplane on this one. You have a tutorial on this setup with arduplane?
Well not specifically! General Ardu setup is pretty much the same for most planes! And this one is pretty much bog standard!
had this plane on order for a while now and finally banggood have managed to send it via the rail service that they originally stated was not available and ive been waiting 4 weeks for them tp actually ship it but its now on its way and im really looking forward to it arriving.
been looking at your blog on this plane and i can see what you mean about the motor cooling vents, did you make any mods to yours?
I plan to make some angled deflectors inside the nose out of foam board that will point the airflow inwards towards the motor instead of it just flowing past it, the motor bell appears to be parallel with the vent holes so diverting the airflow to the motor like that should be pretty simple.
What is your opinion on the stock 1050kv motor on 4s now you have run this plane for a while?
i have a number of varying sized 3s packs that i can parallel up but also a 8000mah 4s which im sure i can balance if i mount things like the gps and vtx in the tail and the FC right back as far as it will go, ive seen one video where someone flew on a 16000mah 4s, he taped a wrench to the tail to balance it lol!
Yeah... I guess the motor can use a bit more cooling... if you use more throttle it does come down hot! As for the 1050Kv one... works well on 4S, just don't go full throttle for too long! As for the battery... as long as you can balance it... you can fly it! :D
@@ArxangelRC you reckon that with forced air cooling the 1050kv could handle longer periods at full throttle on 4s or should I stick to 3s, I tend to fly at full throttle all of the time lol.
Weeeeell... full throttle all the time might be a tad too much... not sure how cooling would affect that... tests will be needed!
Awesome, Can she fly on 4S out of the box or did you change ESC. Which one has a better smooth locked flying, this or the ASW28? Thanks.. i can see that you used a 4S 6000mah but not sure of the upgrades you made .. BTW, I only changed the esc on my ASW28 to use 4S with 13inch prop, without changing the motor, is this ok? Thanks
Thanks! I think the stock ESC is 4S, so it will handle a 4S battery, sometimes I replace these, other times I don't, but in any case it will be a good idea to use a higher quality one, if only for the peace of mind! Also, replacing the plastic servos... if memory serves that they are indeed plastic, is also a very good idea! Actually it is a MUCH better than than replacing the ESC! Also, use a quality external SBEC, not the one in the ESC, to power the servos... at least that is how I do it 99% of the time! The weak point of these, especially if were are not talking about the slower Kv motor, ARE the motors, the 1050Kv one, if I recall the number correctly, would be hard pressed with this 13" prop! The 850Kv one should be able to handle it, but avoid higher throttle, and if you give it full throttle... make sure it is not for more than 2-3 seconds! These have been known to burn out pretty easily! Luckily mine have survived so far!
@@ArxangelRC thanks for the detailed explanation. Really informative. My regards 👌
@@user-rx8qq8sk9ydv1ce5ib You are welcome mate! Good luck! :)
Excellent review 👍 It sounds like one would be better off getting the kit rather than the PNP and supplying a better motor. I saw where you mentioned issues with iNAV, can I ask what the problem was? Cheers
Yes, the kit might be a good option if you know what you are doing and have parts! Replacing the servos is also a good idea... a model this big with plastic servos is just absurd! As for iNav... it tried to kill a few of my planes a while back... so scrapped it... besides, ArduPlane has always been absolutely reliable for me... don't see why not use since it now also runs on the same boards!
@@ArxangelRC Plastic servos is reason enough to get the kit! I'm running iNAV on a couple of multirotors and an S800 but I've never tested its mission capabilities - from your description it sounds like that feature is not quite ready for prime time. I've also used ArduCopter in the past with some success and now that ArduPilot has been ported to the Matek F722 I may give it a try in a Bixler 3 build
Actually I didn't even get to testing iNav's mission capabilities... you need a separate app to set that up... it is a mess! ArduPlane just works... it is that simple! I am not trying to make it do wonders, and it just works!
@@ArxangelRC You're right - ArduPilot is nigh bulletproof. Unless I'm mistaken the latest rel. of the iNAV configurator has a mission planner built-in though I haven't seen a demo of it in action. Cheers
Even so... not touching that, unless it is for scientific purposes... :P
which one do you think is a better glider: phoenix 2000 V2 or 2400?
Well... the 2400 for sure... it has much larger wings... at not much more weight!
how did you manage to speak so quickly ? did you have this text on the paper ? I purchased same plane ( end of 2018 ) VOLANTEX 2400 from BANGOOD and it was $93 USD shipping included from CHINA to Canada just KIT no PNP,
Yeah, the Phoenix KIT version is quite the deal for a 2400mm plane! Awesome quality! Yes, I do read a scrip, otherwise the audio is too annoying with pauses, etc., doesn't sound good!
Hello.
Your Videos are Great.
Do you know wich prop size is the Right with the 850kv Motor and 40 amp ESC?
I have been running a 12" prop on 4S with that motor, and it has been good!
@@ArxangelRC yes But wich pitch?
12x6, 12x7, 12x8….
@@olekolef773 Depends on how much speed you need! 12x6 should be OK.
So what should I go for, the Phoenix or the ranger 2400?
Depends on what you are looking forward to doing with it! :)
Gread review! How does 2000 version differ from 2400 version in terms of flying characteristics? I'm considering both but the smaller size of 2000 version should be easier to carry when hiking.
Yes indeed, it will be easier to carry while hiking... although... the difference isn't that big when it is pulled apart! But the 2400 does have more loading capacity at pretty much the same weight, so it can go slower and it is more floaty... which I like! :)
@@ArxangelRC Great I bought the 2400.👍
Congratz!!!
@@gsf1200s it's supposedly more prone to tip stall than the 2000 though
another great one! are you running inav or arduplane on that omnibus f4?
ArduPlane... I just can't trust iNav anymore!
What's INAV ;-)
@@ArxangelRC What particular trouble were you having with INAV? And what version were you running? I've not encountered any major problems so far.
Haha, right on Barry!
@ Davie: It tried to kill a few of my planes, so I stopped using it before it could actually have a chance to succeed! ArduPlane has been perfectly reliable for me for years now, and now it runs on the same boards as iNav, so really no point in using iNav!!!
Would have been nice to see this plane fly without modifications so there could be a comparision.
What modifications?
Isn't the 850kv version available anymore? I ordered the one from your description in a rush and apparently it is the 1050kv version.. Tried to look everywhere online but couldn't seem to find one.
Damn! There are 3 listings for this motor, all at different prices... and all for the 1050Kv one... and I am pretty certain that wasn't the case a while back when was uploading this video! At least in the photos the linked motor was the 850Kv one! I have no idea what happened... see no reason they would stop selling it!
I know right! Guess there's no other option then fitting a 1050kv version in for my 4s setup...
@@SemteVruchte Well I've ran that motor on 4S, and as long as you don't overdo full throttle... it does fare OK!

Dose the 2400 have the same fuselage, did the wings of the v2 fits in the 2400
No, the wings on the 2400 are larger, so they are not compatible with the 2000mm model!
Thx for info. What a pity, so i can not use both as spare parts, nevertheless i will grab also the 2400, seems a great plane
@@chrisscotty4518 Yeah, sadly you can't use them like that, but the 2400 I liked a bit better than the 2000! Flew better more stable at low speeds.
Do you think an Auline 9600mAh 21700 4S2P Li-Ion at 573g will fit?
Well... depends... it should fit, especially if you remove the battery deck and put it on the floor, may need to trim the wheel cover. The battery will need to go back though, otherwise plane will be quite nose heavy!
@@ArxangelRC I'll have to give it a go, Also, I'm upgrading the ESC to 80A and adding a Matek F765, Will the stock motor handle 6S? Or would I have to throttle limit it?
@@PhenomonAwesome I am not sure, have never tried this one on 6S, if you limit the throttle, it should be OK, won't survive long at full throttle for sure!
should i use 4s if I use the 850kv with 12x80 prop?
Yup!
@@ArxangelRC ok... And how much amperes would it take or what kind of esc should I get or is the Standart 40a ESC ok?
@@nanonatronaviation6007 40A is OK! :)
Hello, All good stuff, thanks! I have a question about how you set up flaps in INAV. Please could you share?
Not using iNav! I always passthru the flaps channels to the radio directly and not through the autopilot!
@@ArxangelRC try this ua-cam.com/video/UOlcEpSsdfw/v-deo.html
Alright, sure... but I am not using iNav... :S
How much weigh can it carry?
Have not tested that... but the wings are capable... so it will easily carry a larger battery too... but space is limited...
Sorry I'm late...Didn't get the notification ;-)
Nice video! That heart shape was so accurate :P Damn it flies slow!
Yeah, I was surprised about that too... the shape turned out quite good, despite being small! As for the slow... it is impressive!
Have you tried thermally it?
Yes, I have... it does pretty well!
Where u flying at
Sofia, Bulgaria
So the KV of the motor has zero effect on the efficiency in an of itself. for a given voltage, a lower KV can spin a bigger prop without burning up, so that may help, but he KV itself makes no difference, just to be clear. The Diameter of the motor armature, (length of the lever), and the prop's aerodynamic efficiency, (largely based on it's disk loading, all other factors being the same) is the primary factor for low powered models, with relatively slow airspeed.
other factors :
the voltage, higher the better, as it allows smaller wires and ESC's.
The prop pitch, profile, and airfoil.
How clean the air is entering the prop arc. (this kills efficiency on most pushers)
how clean the accelerated air is after the prop ( this kills efficiency on single engine tractors which have the fuselage, wing roots, and tail in the prop-wash)
how balanced the propulsion is (counter rotating props balance torque, and need no trim/extra drag). all single engine aircraft suffer from this in handling and performance. Also the angle at which the prop arc encounters the air in flight. angling the prop up or down to compensate for the motor being too high, or low, such as in most pushers, and single engine tractors, and angling the motor to the right, or left (to help to partially counteract P factor, torque, or gyroscopic precession) will result in a loss of efficiency of the propulsion system.
The overall airframe efficiency for a given purpose (important to define the optimization of the aircraft) is also a factor in the overall result.
Whether you're trying to get max distance or endurance, or just want to tear around the field for fun for a few more minutes (or hours), all of these things are important, and very few of the designers seem to understand them, or care.
there are some aircraft that get it right. such as the MTD, and other twin pushers with counter rotating props. some have other design issues, but that's a different subject. These are the workhorses, and will exhibit the highest efficiency for a given task. this volantex glider, with it's large span and tiny single prop (even if they put a bigger prop on it) is just a toy, as the designers obviously do not understand propulsion systems.
Quite exhaustive! :) As usual!
Obvious in this case the motor size is the same, so is the prop, and the voltage, only thing that changes is the motor Kv, which now has less thrust, but also brings about a higher efficiency because of that, all other things being equal! When I put a larger prop on it, sure, top end current will increase because of the higher load on the motor, but cruise speed current, etc., should still be more efficient than the higher Kv motor with the smaller prop on the same voltage!
Umm.. does not seem as if it's being understood fully...
So in the circumstances you mention, will take less current, but with the same prop, and same armature diameter, efficiency will be exactly the same. The idea behind the lower KV is to swing a larger prop, have more disk area, and in that way improve efficiency. Same thing can be achieved by limiting the RPM in software to save the motor from burning up while using a larger prop, but most ESC's do not have that option. You could do it in arduplane for some flight modes, but would have to calibrate the ESC every time it's powered up, which is not a bad idea regardless.
Anyway, If you really want the best efficiency out of the model, use an even larger prop, a low KV motor with as large an armature diameter as practical without interfering much with the overall aerodynamics, and a higher voltage.
Don't take my word for it, It's based on known Physics. check this out:
Some info about the motor diameter, and how it affects efficiency:
cafe.foundation/v2/pdf_eas/2008/alan.cocconi.optimized.electric.drive.systems.pdf
the important bit is here:
"Motor diameter- efficiency tradeoff
With direct drive motors the efficiency and mass may be optimal at a diameter that extends beyond the minimum fuselage or nacelle dimensions.
In these cases the motor design procedure must include the tradeoff between the estimated drag increase of a larger motor and the the incremental power savings from the increased efficiency"
This is key fundamental information, and although you're not going to build your own motor, and design the airframe around it, it's still helpful to know what you are doing, and apply it to the hobby aircraft when making design decisions.
let me know if you have questions. I may or may not be able to answer all questions about the subject, but will help where I can, and say if I don't know.
Once you understand the basics of propulsion system efficincy, you will not be happy with most hobby products and manufacturer's claims about them. Part of the reason I quit doing reviews, and started designing my own aircraft...
I do like your reviews very much, and you're doing a great job, just trying to help! cheers!
@@ArxangelRC
good info, thanks Spike
@Bravo Golf: he is right, have some respect please!
@FPVREVIEWS: I do understand the theory behind all of this, have been applying it to the twin models on 6S for that very reason - lower Kv, larger motors, larger props, better efficiency! Now, since the motor is on the inside of the plane here, I can't go crazy with the size, but I can lower the Kv of the existing size, and go for a bigger prop, which should arrive soon, so I will be able to test it out, but even so... I do like the efficiency I am getting out of this one though, even if it is purely coming from the fact that the motor just can't spin faster... it is still good and only goes to show that you don't need a monster motor in there to make that plane fly!
@@ArxangelRC Roger that! Comment removed.
Lattest consensus is that the 2000 Is the best for many reasons
Less sluggish , less prone to tip stall , just two of the reasons
Less prone to tip stall?! Exactly how did you manage to make the 2400 tip stall? Because I sure couldn't, and believe me... I tried! I pushed it hard... slowed it down A LOT... and it just kept level wings and took it!
@@ArxangelRC Not me haha
I wouldn't have thought so either , but have a talk with either Andrew Newton or .. ..
.name to follow when I remember .. umm ..got it > Brian Philips ( you tube reviewers , ) but not company bitches haha .
@@jackd1582 Not sure what their experiences were, I can only speak for my own! :) Given the choice, at least for my type of flying and personal preference, I would go for the 2400!
@@ArxangelRC Yes ...to " type of flying"
@@jackd1582 :)
Are the wing slots the same as the 2.0?
Nope, these are bigger, the wings will not fit on the 2000!
@@ArxangelRC I saw this version two days after ordering the 2.0, great fucking timing, THanks
Sorry mate, physically had no chance to get this out sooner! Has it shipped already?
@@ArxangelRC Ive been flying it, got in late Dec. great plane but would have bought the 2.6 for sure, thanks
The 2.6m wing span one is the older generation though!
and now I have a 2000 and a 2400 :>
hahaha, not a bad combo! :)
Which one do you think is a better glider?
@@tommasoviani8949 guess ..... .. 2,400 probably better in light wind conditions . 2000 better in slightly more wind
What city is that?
Sofia
Where dat Ranger 2400 vid?!?
It will be coming... have to finish up some other stuff, and its autopilot install! :)
@@ArxangelRC Awesome! So excited to see it, I'm loving the Volantex series. Thanks for covering these models. I'll probably pick up my own for the summer
Volantex do make very good planes... and they do listen to criticism... although are a tad bit slow to react to it! :) Lots of new Volantex planes coming soon... but smaller! :)
Holy sh*t that video is made in the city of Sofia, capitol of Bulgaria I`ve recognised it because of the tall building at 5:00 min. that building is located by THE INTER EXPO CENTER at the south-east side when you enter Sofia coming from Plovdiv city....
Yup! :)
Is this better than the asw28 ?
Depends what you're going to use it for!
ArxangelRC well I wasn’t planning to walk the dog with it...
Hahahaha... both are actually quite different planes! :) This one is quicker and a bit more agile... the Phoenix 2400 can be more relaxed for sure!
ArxangelRC cheers! I’m going to go for the 2400
A wise choice! :)
Can you catch good thermals with it
I suppose... have not played around with those too much, although I did some... and it was pretty good, at least in my experience... which is not very extensive! :)

I am sorry... can you go in English?
Its ok breath when talking :)
Breathing is overrated! :P
DONT POST these videos..... I am broke. Lol
Hahaha... aren't we all!
