Best find out why it lands real fast first...It will be one of two things, either the wrong approach (!) to landing the thing, or the wing loading is high and the drag low. Either way flaperons won't help much. The reasons are many and expounded upon at length in other threads in this forum. To answer your question with a bit of positive input we need more info, what it is, wing area and section, AUW etc.
