I haven't flown the plane yet but i have a 60 size seagull yak 54 with dual elevators and dual ailerons. I have the 7C 2.4 ghz. The 72 mhz version doesn't have this feature.

ps the manual is online so if you havent bought one yet and you want to pre read the manual for insight. its the ailervator feature and the dual ailerons are the flapperons.
