RC P51-D Mustang FPV (on board). Engine failure. Flight three. 

On the last flight, I was struggling to get the performance out of the 3s electric brushless combo. Since upgraded to a 450kv brushless motor with a 50 amp esc powered by 4s 14.8v lipo. In this flight we have a real engine emergency
Flight Review:
After takeoff, climb to altitude. Then returns down to initiate a low pass. This is followed by an aileron roll and a second slower low pass, which hits the runway at (1:40). The south-to-north direction low pass with the wind on the tail makes for a fast pass. More aileron rolls and full throttle for the majority of the flight. During the flight, a real plane is seen on the GoPro. A stall turn turns into a spin, and then altitude is gained. For an inverted stall entry, spinning almost uncontrollably before levelling out. From the ground on the last climb, following the twin aileron roll and one more controlled pass, I noticed a small trail of smoke. At (4:38) the engine burns out in midair. The plane was not in the best position for this, but I made a steep approach to flare out and crash land.
