Yep, this time i've rebuild one of the craziest of my drones - Piranha Dragster (https://rotorbuilds.com/build/5274).
All components should be able to run 6s batteries, be more powerful and reliable! What I did not change:
ReadyEdi RE228 Frame is great and I like it.
There are no complaints about the EFAW motors. They are Lipo killers, but very strong and they have great thrust!
RunCam Eagle2 works fine so far.

So, main changes were fc (Matek H743-Slim), pdb (iFlight SucceX PDB 2-8S), escs (Tekko32 F3 Metal 65A) and vtx (TBS Unify Pro32 Nano). To prevent voltage spikes I added four 35v 220uf each and one 50v 470uf capacitors. Also I added gps module to figure out top speed of this dragster.

what is the top speed? :)

So far i didn't measure the top speed of this build, but previous modification was able to reach 193 km/h with 5s battery. Main problem is battery sags. Motors can't reach top rpm, they draw too many amps.

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..
