i have a 23% 90 size edge from powerline hobbies. i want to put an engine in it that will allow it to have a greater than 1:1 power ratio and that i can put a smoke system in later. the recommended size is 90-120 2c and 120-160 4c. there don't seem to be many 120 2c engines around and a 160 might be too big. the planes weight is 9-10 lbs. ready to fly and a 73 in. wingspan and an 800 sq in wing area.. also, is a gas engine a possible choice for this plane? who makes smoke systems for gas engines? is the os 160 FX a good choice?

I would check out the MVVS line up myself. I was at a fly in today and witnessed two Ultra Sticks with Gas 1.60's on them. They were spinning very impressive RPM's, I know my next plane will have one!
