I dislike my Tower Hobbies Trainer 40. It came with severe wrinkles and took over 4 hours to iron them out.
the main landing gear squats so much that the tail almost drags in the grass. I've tried to bend it into shape but the rods refuse to adjust correctly.

It also seems to be a bit unstable. Of course I'm a beginner but I can tell that it is flying strange compared to my sons solo sport trainer.

I've checked the balance and it is a little nose heavy. It pulls hard to the left which I think I can correct by adjusting the engine in its mount. Could account for the slip like flying qualities.

So far, I would have to say I'm not much of a fan.
