RC P51-D Mustang FPV (on board). Flight Four 

On the last flight, we had 4s 14.8v lipo cause flight, we had a real engine emergency. Since then, I've changed the motor to a 1000kv e-flite. And reduced the propellor from 11 x 8.5 to 10 x 6 to keep this engine from burning out too.
Flight Review:
After takeoff we kick left into controlled circles to climb and level out. Then a throttle back glide test into a low pass. After a half cubic 8 we start pulling out from a vertical dive the wings level out as we pass the fences. too close for comfort this would have been catastrophic if we didn't have the crucial height. Then a low pass with the shadow racing alongside. You can hear the undercarriage scrape the grass at full speed. After this a climb back up with one roll ends in a very average landing with lots of rudder inputs.
