You rearly ought to check out the latest VMar kits, your comments relating to them are now old hat and very out of date.

Latest Arrow Tiger in Europe is now a see through red scheme the aileron servos are not under a cover but exposed as per every other ARTF now days, only problem I had with the whole build was the incidence pins for the wing joint being out of position, I had this with a Graupner kit so no big deal, the work required is just enough to make you feel involved in the construction sequence and having contributed to the build.

I'v put Ailivators on mine so the elevators also act as ailerons, seemed to good a chance to miss as the twin push rods where already there, pics should explain mods required.
