My 15 inch long-range setup for 2020 (with CAD files)

Image
This is my latest 15 inch ultra-long range setup with 50 minutes flight time:

Propellers: 15x5.5" Tarot with custom hub Motors: T-Motor MN3110 470 kV Frame: 240g custom carbon structure Lipo: 2x 4S 4000 mAh SLS 20C (parallel) Camera: Micro Runcam micro sparrow Firmware: INAV FC: Holybro Kakute F7 ESC: Tekko32 F3 GPS: BN-180 Compass: QMC5883L Receiver: FRSky R9 slim+ 

Hovering flight time is 50 minutes at 8.5 Amps and 40% throttle. Current goes up to 12 A when flying 50-60 km/h. Flight characteristics are really good when tuned properly (you'll nee a HUGE D-term).

Here is the CAD file of the frame.

INAV 2.4.0 PID settings: 
set mc_p_pitch = 85
set mc_i_pitch = 60
set mc_d_pitch = 150
set mc_p_roll = 85
set mc_i_roll = 60
set mc_d_roll = 150
set mc_p_yaw = 200
set mc_i_yaw = 70
set mc_p_level = 40
set mc_i_level = 10
set max_angle_inclination_rll = 500
set max_angle_inclination_pit = 500
set dterm_lpf_hz = 30
set use_dterm_fir_filter = OFF
set yaw_lpf_hz = 50
set dterm_setpoint_weight = 0.600
set …
