I would be curious to hear the answer to this question as well. I am thinking about adding aelerons to mine and since I will be jacking with stuff anyways would a motor upgrade be worthwhile? I know my SuperCub likes to climb on its own when i have the factory motor at full speed. I couldnt imaging having much more wind going across those wings. I would imagine it would just pull it straight up? I am not famiar with predicting flight chartoristics tho. I am anxious to hear the answer to this as well...
