100% Throttle for a minute straight! X Class Cobra Powertrain Testing

If your looking for a reliable X Class setup, that won't completely break the bank, look no further. Based upon the thermal results, you could get away flying this rig in Death Valley and it would be fine.

Powered by Cobra 4515 435kv Motors, and their 60A Wing ESC's, it swings 13" Master Airscrew Tri-Blades with 12" Pitch with ease!

The frame is a Dysonian Soul which is hand made from aircraft grade 6061 aluminum, which is 800mm motor to motor. At the core of the power system is a Dysonian Bus Bar PDB, that is being fed 10 gauge wires with 8mm bullets from the Hyperion G7 90C HV 5200mah battery.

Flight Controller is a BrainFPV Radix, which does a great job at handling this bird. The FPV camera is a Runcam Eagle 2 16:9, that is hooked up to a TBS Unify HV Race, with a Foxeer Lolipop antenna.

This rig is running Betaflight 3.5, PID's and Filters are as follows:
Dynamic Filter: Off
Filter Type: PT1
Gyro Notch LPF Cutoff 15
Gyro Notch 1: 85 cut 25
Gyro Notch 2: 245 cut 170
D Notch: 100 cut 30
Gyro/Pid Loops: 4k/2k
ESC Protocol: OneShot125 (No Damped Light)
Roll: 46/51/58
Pitch: 40/38/60
Yaw: 55/35/10

Note, above PID's are still a work-in progress, Pitch and Roll need more D, and Yaw needs more I for sure.
