I have a 66" Vector Flight Extra with a OS 1.20 pumped engine on it. I have 6 flights on it now.
WOW, what a responsive airplane. Mine would snap a little when pulling hard on elevator.
Using a Futaba t6xas transmitter and Hitec 645's, elevator throws were at 40%, reduced them to 30% and the snap
seems to have dissappeared. It takes very little elevator throw on this airplane. Floats in on landings.
Great airplane...everyone should have one.
