I'm real ---- about checking my surfaces before flying, but a few session ago things only went wrong after checking. While taxiing to the far end of the runway, I ran over a small piece of tumble weed and it lodged itself between one of my elevator counter balance and the end of the stab. I only noticed it right after rotating on take off when one elevator jammed in the up position, and if I hadn't already known how to harrier, I was about to learn real fast. Got her down without a scratch, but the pucker factor pegged the scale...

Also...what is a glow plug...and why should I put one in my plane?

I think he meant spark plug.
But could be the high-current motor to speed control plug?
You're right Randy...but then I was trying to be smart too!

Way to go Ron.......you got Randy all confused.

Your instructor did you a HUGE favor!!!!!!! You should thank him again the next time you see him. The issue on this one was what is called pitch coupling. The plane was an aerobatic mid wing type plane with no dihedral. If the plane is not properly trimmed, using the radio and various methods, when rudder is applied the plane pitch down suddenly and rolled at the same time but not in the the same way your trainer would. A trainer (dihedral high wing) is very stable so it will return to wings level once rudder or aileron is neutraled. A symmetrical low or mid wing will not return to wings level on it's own, it is less stable. You must make a control input(s) for the plane to return to level. This is the huge problem with reversed ailerons. Your brain keeps making the problem worse.
Had the plane been properly trimmed however (I am talking about more than just straight and level adjustments with the trim levers) it would have been possible to get it back using rudder with very small but easily adjusted for aileron. Basically flat turning the plane back.
If I ever have to get someones aerobatic plane back with reverse ailerons I think I will try to do it inverted, at least it will pitch up
What caused the ailerons to be reversed? If the wrong model memory was selected, It wouldn't matter whether or not you'd trimmed out the pitch coupling or not, since you're on a different model anyways!

I don't know why they were. I can only speculate. The point however is to check before every flight and especially before the first flight. Before the first flight of the year or maiden I always ask someone I trust to look over the plane and check the movements.
