RE: What is it?
Look at the first picture where the control horn and wire from the aileron can be see. Then look at the position of the "Kick Start". I wonder if it's rigged up so the aileron pushrod hooks into the "Kick Start"?
Any chance of seeing some picture of the inside? I doesn't look that bad from the pictures shown, and most likely would be a lot cheaper to fix up money wise than getting a new trainer.
