There are many good electric aileron trainers listed in the Hobby Lobby catalog. If you want a good trainer type but are not wedded to the idea that it must be electric, look at the RCM TRainer or the Sig LT40. They are both ARF's. Electrics available from Hobby Lobby that have ailerons are a twin SWIFTBLU or RED, a Grumbler and a Tipsy Nipper to name a few. There are more including scale fighters. Ask for catalog #41.
