The esc maybe salvageable as it looks like it may have just overheated and enough to desolder the fets, to be honest the worse looking one is outputting to motor 4 and is not desoldered. I'd try getting them back into position with a heatgun and see if they are detected in blheli afterwards. I've had luck doing that with another esc more than a year ago and it's still running today.

Yes, it should be salvageable, but missing parts are lost in the field. I may have another broken one somewhere, but I have no time to work on it.

I know how that goes! I have had a Foxeer F7 and Reaper 8s 80amp esc 20x20 for over a year know I've been holding onto for a project to use in but have not felt right about putting them in just another quad. I could see building one of these speed drones through but I have yet to find any prints for it online and am shit at designing myself. If you know any public files I'd be very grateful for a link.

Also gotta flip those motors somehow. cg is way too far away from the line of thrust. Ask me how I know :)

Next thing ya know is DARPA will make something like this for use as a kinetic weapon.

Alien79   Feb 02, 2021

need some cooling through the pod.. i recommend NACA low drag ducts

Alien79   Jan 29, 2021 

Yep, you are right, a bit of forced airflow would help cooling parts, but i didn't get there, just got a very heavy vibration after arming, then after 3 seconds of hovering it dropped and everything was melted already.... sounded like a grinder :(

thats too much dterm. for 6s your gona need to tune down the whole pids a good 20%. use dmin and not worry about propwash.. these quads never fly that great over all so you tune should be about not setting fire too it

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..

With 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..
