RE: Which plane would an instructor fear the most?
I have flown 2 different Raptors. Both were/are terrible. The power is the biggest issue. One of these has a Rossi 45 and Macs pipe on it. With a 60 it might be fun. With a 45 even a split "S" is hard to gain enough alt without stalling it. No way would I try and teach someone to fly on one of these.
