Last week I experienced a magneto failure during run-up...for departure to the Corvalis Corkcrew IAC contest. :cry:
I flew Sportsman (poorly) in my RV-8.
This weekend I worked on the Yak. Of course, I started by accidentally selecting the wrong mag to disassemble.

I called Cliff Coy at Motorstar NA about converting the M14P to electric start. The conversion adds 15 pounds to the aircraft, all at the nose. The reduction gear case is modified to mount a starter, and a ring gear is mounted to the propeller shaft, similar to a Lycoming.
