Default RE: Which engine?

ORIGINAL: zax2000

I am leaning towards the Zenoah because a near-new one seems to run just over $200 while an Evolution 26GT seems to run just under $400. The G38 could fit in the cowl without the muffler but I am thinking it is too much engine for a 18x6 prop. The side exhaust will work great on the G26 but I was wanting to make sure it wouldn't have problems turning it and an 18x6 would be enough for that weight (15-16 lbs.). I'm not looking for performance, in fact, the manual states that all STANDARD servos were used and are recommended! Just precautionary, I'm using about twice that torque on ailerons and triple on elev/rudder.
The G-26 will turn a Mejzlik 18x6 around 9000rpm (I believe Ralph has stated) and produces about 17lb static thrust. That should be lots to get a lightly loaded floater into the air in short order.
