with flaps over top .. no problem.
I did it at 125 ias first.. took it to 110 and didn't try to go slower. still had control with airspeed below 75.
started level at test speed.. hit wep and took it over.
tests done 1k~3k.
bug or great performer?
spit9 vertical speed around 125 ias.. but hard to control perfect loop at top.. will flop to side.
