Guys, my eyes are limited for reading (all the previous posts) right now. Do any of you fellows plan to sell a CD ignition for radio controlled airplane use? CH Ignitions here is ten USA has closed. They can do only advice. So we are looking for a source of CD units. The average advance is from 5 to 28 degrees. We use 4.8 volts for power. Can even double the input voltage. I myself would be satisfied with a fixed timing. Being lite & reliable is the main thing. What do you have? Thanks,Capt,n PS this should be a shielded ignition.
