Issue/Fix/WIP
-
Having some problems with the vTX right now, apparently at full throttle. Electrical perturbations ?Good, got some new antennas - What is LC Filter and How it improve FPV experience
Gallery
- 1st flight https://www.youtube.com/watch?v=RCSfAMZ6bm0
V1 Hobbking frame
cabling is hard
1st build
fpv tests
rebuilt everything, better antenna placement, battery cables, fix the feet, ...
Broken an arm trying to roll
Arm fixed using epoxy, flying well, we'll see if it handles vibrations and the next crash
V2 Nighthawk CF
V2 because HK frame broke again after ~10 landings, CF frame, looks nice (not tested yet)
V2.1 Cleaner build, new motors, new VTX, new FC
V2.1
