First off with the translation, pants equates to crap and ic as in engine powerd flight as oposed to battery

I know it sounds silly, but I was mickey taking people down the hobby shop today for giving the same approach to helis as I am to planks.
People come in, look at the scale helis, wave the magic plastic then get shown reflex on a pc and given a chance to fly. Their faces drop and get shown plastic fantastic indoor helis.

Thanks for the advice and giving the better understanding of the bi plane flying charecteristics
