My thinking is, if it is hooked up to a buddy box, who's fault would it be if it crashed??? MINE

Now if it is not my plane and I'm helping someone, then lets say the wing breaks in 2 because he didn't glue the ply wing joiner in. That's not my fault, cannot check that in a pre flight inspection.

Anything that goes wrong and can be checked easily, thats my fault.
90% of the time a new pilot will not blame the instructor anyway, but I'm not afraid to take the blame. If it is my fault I will deal with it.
Since you are posting on this forum, you have more knowledge than the guy that flew my Zen. He said I could fly from his property IF I let him give it ago. So I let him........ It was abit more plane than he was ready for but he enjoyed it and bought himself a Tiger. (that I helped him build and even let him use my old 4 channel radio). He learned to fly that and now has one of the Tiger 60s also. (come to think of it the jerk still has my radio )
