i've posted this before but didn't get what i was looking for. 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 for a glow engine?
thanks

electricfan, a friend of mine has a 90 size edge and he has a 150 saito in it and it does any thing it smokes.............dep11.
