The Ummagawd Acrobrat design is flawless. A very stable, resistant and jello-free frame. Maintenance is easy too, but there's no much room inside, so you have to measure pretty carefully every wire, and take advantage of every millimiter. Without tons of TPU and the correct tweaks on Betaflight, flights like a 5" even with GoPro Hero Session on 4S 850mAh Lipo.

A little bit to expensive since I didn't find a decent 30A BLHeli32 20x20+VTX stack, but at least I know I can punch it to the moon without burn anything (I'm looking at you, Mamba!) I won the FPV camera on a racing competition, but will be replaced by RunCam Racer 2 in some weeks when I get some money.

And don't forget your favorite low ESR capacitor to get a cleaner image ^^

UPDATE: camera was replaced by RunCam Racer 3. It's a w e s o m e.
