I agree with "leave the co-pilot out of the plane while training". I took a Hobbico Brightstar up for someone for their second plane on the buddy box. Every time I gave them control they did fine until they turned the plane. The plane just stayed at an angle and started to lose altitude. It turned out that they had gotten used to the self leveling aspects of their trainer, let the sticks centre and the plane would level out. Of course it didn't work on the low wing plane! Now if someone trains using a co-pilot and gets used to letting the co-pilot take over for them, what kind of a pilot are they going to be?? What happens when they start flying a plane that doesn't have one of these things in the plane? I think it might have some uses for sport flying, but forget it for basic training! :stupid:
