I have an RCS 1.40 that's going in this bird for now, but I may want to get something with more power later. I need an engine that will hover and be able to pull out right now. 3D is not important yet... but once I get my spins and hovering down I WILL start to work on 3D. Will the RCS fit the bill or am I better off selling it and getting a 2 stroke glow engine? I plan on putting a 9252 digital servo on the rudder and some cheap high torque servos on every other surface. (GWS BP148X 2BB - 1.62 oz, Torque: 78 oz.in, Speed: 0.21 sec./60° at 4.8V).

How much gas do the large glow engines go through? Right now I'm loving the efficiency of gasoline. I can spin an 18X6 at 8000 RPMs (8400 when lean), what would I expect on glow?
