- ESC: Afro 12A SimonK (2-4s lipo), BEC: 0.5A Linear 5.0v
- Motor: DYS BE1806 2300KV
- Props:
- 2 blades: Gemfan 5030
- 3 blades (unused): Gemfan 5030
-
FCU: CC3D Evo 4.8-15V 70mA-> NAZE32 - Batteries: Lots of 1300mAh 30-60C 3S
- FPV
- FPV Camera: 1/3 Sony CCD 7-13V (3S) current 70mA
- FPV Transmitter: 7-24V 190mA manual -> FR1 CH8
- Video Receiver: current 12V 200mA
- Video "goggles"
- Weight: 515g w/ battery (60C)
Upgrade planning
- Props 5045
- better frame
- expensive 150$ http://www.minihquad.com/frames/blackout-mini-h-quad/
- cheap 20$-40$
- Better FPV antennas, stock are shitty with Skyzone kit (according to comments on HK)
- Motor: EMAX MT2204 2300KV 7.5A, 2-3s, max 90W
Old setup
- Frame: HobbyKing Spec Class 250fpv
- Motor: 4.4A max, 2-3s lipo, max 49W
- FCU: CC3D Atom 4.8-15V 70mA

Batteries
- https://www.reddit.com/r/Multicopter/wiki/power
- LiPo are dangerous! https://www.youtube.com/watch?v=YCWdnjLqVWw
- C rating : the higher, the higher current you can draw http://www.rcheliwiki.com/C_rating
- C*Capacity in Ah=Current
- Current: 20C * 2.2Ah = 44A
- Power: 44A * 11.1V = 488.4W
- S is the number of cells in series, and is representing the tension (1S=3.7V, 2S=7.4, 3S=11.1V, ...). P is in parallel. Usually LiPo are in series and P=1
- Balancing: Cells need to be a the same charge level so we can avoid overcharging.
- It's a good idea to always use the balance mode to charge a multiple cells battery
- http://www.rcheliwiki.com/Balance_charger
- Use the charger to check and rebalance cells https://www.youtube.com/watch?v=AChoy_PsVEg
- A good trick to test is to charge the cells individually using the balance cable, it's much faster than the balance mode that needs to discharge overcharged cells a lot
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
