I will be starting to build a Dynaflite Chipmunk this fall. I have not as yet determined what engine to put in it. I would like to install a gas engine in it but due to the limited width of the cowl a Zenoah G26, even with a Slimline wraparound muffler might be too wide. A Zenoah G38 would fit because it has a rear exaust, but i'm concerned about the extra weight it might add to the nose.

If anyone has built a Dynaflite Chipmunk please respond and let me know if it was tail heavy and had to add weight to the nose to balance.
