Anyone care to comment on a good engine for these models? I was thinking G26 is the way to go. Anyone using something else?

I have read several posts on the G-26 as an exellent choice for your plane.
Nice match, I say go for it.

I have an RCS 140 on mine, flies great.

Yep. G26.. Abell muffler 39.95 16/8 apc STOCK PROP BOLT.

Check out the GCBM R/C Models Inc. 25cc conversion engine. About $100 less than the 26... www.gcbmrc.com

I never heard of this company, but the stats do look interesting.

Got a Brison 2.4 on mine. Right now they are $377 and $30 for the muffler-- You probably will need to replace the muffler on the G23 or 26 anyway to get it concealed in the cowl. So for a bout $100 more you get an engine you can use on many planes to come and more power than I can describe. I still fly mine scale with a 20/6 prop and B&B smoke-- but it also doubles as a funfly with this engine. Super combo for just "show'in off"--

Yeah, me too on the 2.4. I've got a zdz 40 and use this power for aerotowing.
