You just can't beat a YS 110, 115 or 120 for that type of airplane. Great power, easy to tune once you get the hang of them, they allow you to place the fuel tank on the CG and if you need assistance tech support is fantastic through YS Performance and there are a bunch of guys here on RCU in the scale racing forum that easily have a combined 30 years of experience running them, the pattern guys have a wealth of knowledge as well.
