Tim, thanks for the link. That one did not pop up on my internet searches. My Google-Fu must be weak. I have an e-mail in to them to see what the max RPM of their lightest system is. The highest they show for one of their ignitions is 12K, and I'm looking for around 14K. I'm looking at doing a .15 sized engine turning an 8 inch prop. I suppose I could go to a 6" or 7" pitch, but I'd like to stay around 4" or 5" pitch.
Dane, I looked at that site, but it seems to be only for points ignition engines, and the engine I want to play with is not a points engine. But thank you for taking the time to look for me. (edit: Oops! looks like they do have an option for the TIM4 with a Hall sensor. I'll have to email them for more info.)
Mark
