how about a 1/3 scale or 108 in span Sopwith Camel using brentg's excellent EA and Madratter's RAF FE2b prop on the Moki 180 radial with the 180 Radial sound , smoke on channel 7 pilot cam on F4 , guns on channel 8 full down fire . here is a youtube video of a 1/3 scale Sopwith Camel . one thing i noticed if you import it into RF 7.5 it is nose heavy and will need to have CG moved back some , i found out its due to 7.5 not having the Moki 180 and using what ever engine it picks
