Are you guys talking about the 1/9 Rafale from Aviation Design? I just picked up an older kit ,it looks like it was designed as a ducted fan kit , but the plan shows a turbine. Is there anything special I have to do to convert it to a turbine version such as carbon reinforcement of the fuselage? My kit has a white gelcoated fuse , obeechi sheeted wings and fin, and black fiberglass ducting. Thanks Jack.
