Im using an apc 11x4.7 slow flyer
Yeah it hovers and harriers like a big foamie. Its a blast! It was windy and gusty here today and I "tried" to fly it this morning and almost lost it. It was in a harrier going backwards about 10mph. Vertical punch is awsome it will jsut blast out of a hover. I got a FuntanaX for christmas and I havent touched it since this thing started flying. It may go to the market place. Its just hard to beat the power to weight of a profile they are just so much fun. I already have another in the box as a backup
My only complaint is that is SO delicate, its built like a feather. Flying it is fine but hangar rash could be easily fatal to it.
