So, after a shitload of work with burning flight controllers it is here - Quadstardrones Arx 5r v2 hybrid. First of all - I higly don't recomend Iflight succex mini stack for this built - I've burnt 4 FCs in the row becouse vtx antenna was pushing down the flight controller sitting only on rubber standoffs -kakute f7 mini, having the built in vibroinsulators can be securly mounted on the nylon standoffs guaranting a non problematic usage.
AUW 399g
So, after a short while of testing I can say a few words.
Firstly - vertical arms help with control. I guess it is thanks to the rectification of the air vortex created by the prop. Thanks to this the vector of thrust has less work to do as smaller changes in RPM create more of the vertical force. Once again - it is only my guess.
Unforunatelly, although the controll is much better than in my legit 4h lite the 4 inch had noticably better top speed and acceleration, althought the 5 incher seems to have at least comparable bottom of thrust.
All in all - I am quite happy with this one and can't wait to showing you what this setup can do!

nice a new nice build from you, thanks for share! sadly your issue with the fcs. hope for a dvr.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..
Read moreWith the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Welcome to the club! We are few. And we are proud. Also, if you clean that build up you'll get ALOT more speed out of it. I've got a 6" that does 130mph on 4S 2450kv. The speed can be had, just takes a little work.
Hello! It so nice to see such a warm welcome. I have to change the ESC and one motor so cleaning up electrical instalation will be done. I'll update the photos.
As for the speed - it is reather caused by the size of and weight of motors in the 5 inch class. To achive higher top speed I would need to use higher motors and those are heavy and in consequence reduce the nimbleness of my quad. Thats why I achived it in a 4 inch quad, where I could use high 1408 motors while keeping low weight (also those motors were a trash as they were ripping the windings during small crashes).
As for the Arx - it is very, very good.
Trust me, if you put 2207 mid-kv motors on there and streamline the motor spars you'll get alot more speed out of it. You'll add ~40g to your AUW in motors, but if you remove the motor wire braiding and LEDs you'll make up some of that weight. That's what I'd do if you're unhappy with the motors. 2206 motors do actually make alot of sense on these though! I got a racing buddy I know (way faster than I am) to start using them and it's amazing seeing him switch frames and improve just because of that.
