kykid88,

I have been using a 29cc gasser modified here in the states for model usage. It puts out more power than the 26 and is much lighter on the included electronic ing. (C&H synchro spark). 43oz. and swings a 18x6 Mejzlik at 9400rpm. The engine builder is a performance engine builder and machinist named Jack Canaday. The Jack's 29cc is available now for around 420.00 and includes the ign. unit. Jack's number is 816-528-3937 and he is located in Lathrop, Missouri. This would be an excellent engine for this plane. Price is without muffler but a G-23 muffler will fit
