Jim,
Good to hear from a fellow Troublemaker fan. Mine is about half completed and is built from a J&J Industries kit plan plus additional information very kindly supplied by Freebird.
Just to make things clear the plan shows a small "balance range". In the scan below the forward limit is 130mm from the leading edge and the rear limit 140mm.
I had planned to use an Enya 61CX in mine but didn't appreciate how small the model was until I built it. I think my Enya 50CX will be more than adequate. It's entirely up to you of course but personally I don't think a four stroke would suit this model.

Ray, Nice to hear you're making a Troublemaker. I'm looking forward to some pics of the finished product. Tony Bonetti once gave me some pilot training back in my Tri-Squire days. Actually he just did the take-off and landing for me. He handed me the transmitter in between.
