Thanks guys for your input here. I have decided to go with the ZDZ50 and Bison in cowl muffler for this project. I also have 4 futaba 9250 metal gear digital servos for the ailerons and elevator. On the rudder I plan to use a pair of futaba 9202...I called GP on this and the tech on the phone said no problem. I was worried that it wasn't a metal gear servo but they seem to think it won't be a problem, especially since there is two of them.

Thanks
