The starter itself produces high voltage spikes through out the plane. Possibly the diode trick would work on the starter also but I've never tried it. Putting a diode across any relay's coil is a good idea. The only problem is that when the diode goes bad, opens up, you don't know it and radio's get zapped. Knowing this, a diode of at least 1 amp at 600 volts should be used. That's all I've ever used on my starter solenoids and haven't had any problems.

Rick Lewis >>>>>>>>>>>>>>>>>>>>>>>>>>>>> Rick this is how I approached the problem... it seems to be fail safe and easy. I did not use the diode but I showed it in the diagram to show proper placement.

How many degrees of "up elevator" should there be with the stick all the way back? Also, degrees relative to the main fuselage tube, or the horizontal stabilizer? Bill Sullivan Windsor Locks, Ct. FS 447 >>>>>>>>>>>>>>>>>>>>>>>>> Bill on my markIII plans it says " note there should be approximately 35 Deg up and 35 Deg down rotation on the elevator."

The diode is however still needed to protect the starter switch contacts. The contacts can actually pit without it. Good job, I'll be using your idea in my plane.
