thanks for the reply.. i have heard also about people using the g26 with good results. for the same weight or even a tad bit less i was looking at a zdz sport 40 or a roto 35 or even an rcs 1.4 or 1.8. i dont intend on doing 3d with the plane but i always like to know that i have the extra power in case i needed it. i would imagine that if i used one of those engines i could expect to never really go over 1/2 throttle unless i got into trouble. ive heard that the airframe may not be suited for larger gas engines as well. i would think by using throttle management it shouldnt be much of an issue as long as the firewall has proper support. besdies i like the fact that if i dont like the plane i can always use the slightly bigger engine on many other types of aircraft. i thought i read somewhere of someone sticking a g 38 in one of these planes. they are much heavier i believe than the engines im looking at. most posts ive read though, use the g26 or large 2 or 4 stroke. not sure where i may go with it quite yet, but i would like to use gas if at all possible.. thanks again
