Hi guys,

I was wondering if you could help me out figuring out this problem.

Flew Quad-Plane yesterday (the white foamy drone) and trying to do an RTL. The drone transition from fixed wing to quad mode and was travelling to the home position. But before it could reach the home position, the drone was going full throttle and low throttle alternately a few times and then crashed.

- Below shows the data log of that flight showing the current draw, voltage, altitude and airspeed

- Attached .doc. file shows the Set Parameters that we used and also described the RTL mode function of the Quad-Plane

- Li-Po Battery we used
a. 2 X 4s 15c 4000mAh LiPo Battery.
b. These two batteries were connected in parallel

- Quad Motor we used in shown in the attached .doc file

- Drone MTOW = 3.97 kg
