Skid ... that is totally weird, there is one heck of a long thread in here about the Phoenix SU31, the plane flies well. Also, I have a Black Horse SU31, they are about the same, probably come from the same factory. I flew mine on an SC46 with the APC 12.25x3.75 prop ... it slightly floats in, does not come in hot at all. This weekend I just got No. 2 up with a TT61 (this plane is about 14 oz more than the first), even with the TT61 the plane does not come in hot, slightly fast only.
