drbenz,

This may not be the advice you are looking for, but IMHO the stock (magneto ignition) G26 is too heavy for use in most 3D planes. Good 3D performance requires an extremelly high power to weight ratio and very light wing loading. With a good muffler, the G26 makes about as much power as a Saito 150 (give or take) but weighs substantially more. Also, at least on my G26, the throttle response is not quite as fast as I would want for 3D. That may be due to my setup, however.

Don't get me wrong, I think the G26 is an excellent engine. It's a good flyer in general sport planes like the Ultra Stick Lite, Jerry's Big Boy, scale Piper Cubs, etc.
