Radio die-off


Repairing the peg board had another advantage, like finding out what caused the crash. Found an incomplete flight recording on the flash. The Dean connector did not glitch. Obviously, it lost the radio & went into failsafe mode. That held it in a stable hover for 3 sec before killing the engine. It impacted before the filesystem could sync.

The PIC didn't fail, because she would have spun out of control before engine shutdown. The PIC has to constantly trim rudder & cyclic to damp rates. Have never seen the XBee get anywhere close to losing 3sec of data.

That leaves a glitch in the radio connectors or a 3.3V regulator
overheating. Never saw any voltage anomaly in the flight recording. Need to leave the radio system & all the 3.3V parts on for hours, test range, & wiggle connectors until the problem repeats. Only then do we install a heat sink.
