i have the flair tripe, have tried it with a converted weedeater engine, that didnt work out, not enough power. i now have a super tigre 3000 in it and it flys well. a trick i learned on taking off is keep full up elev until you have some speed then release and tail will come up. then a touch of up and it will fly. if you dont plant the tail it WILL be squirlly on the take off run. on landing keep some power on and land on mains dont try to 3 point her. if you are wanting one for gas i suggest the busa or ziroli. myself i like the look of the longer and narrower gear legs that the flair has.
