i think a lot of extra fuss is made over "aileron" trainers. when a plane turns, it turns, right? who cares how this occurs? the main thing that happens when one upgrades from a basic trainer (like the hobbyzone supercub) to a more capeable model is that the new airplane goes a lot faster and is more responsive, hence requiring more skill to fly it. just my two cents worth. i went from the hz supercub to the pz t-28, like a lot of folks on this forum. this progression worked well for me and other self-taught flyers. good luck! rob
