yes a gasser has an EGT (exhaust gas temp) of around 800-900 F, a glow is about half that and a turbine twice that. also the G20 will fit your 60 size trainer and will also fit allot of the Hanger 9 60 sized ARF warbirds as well as allot of the 60-90 sized kits

kc

EDIT: trainer planes aren't just for training, they are allot of fun to just Sunday fly and everyone i know has put bells and whistles on them at one time or another, we even had a guy who put a Rossi w/ tuned pipe on an avistar, smoke and breaks are nothing new either but to get a cheap system that isn't up to what you really want out of it is just going to be a disappointment. make wise purchases that you can use later on in your RC career, the G20 would be something that'll fit allot of later applications and will last many many yrs, plus the added benefit of they get better fuel economy and fuel is 3 bucks a gallon.
