I have been flying my skyraider II with Supertigre 45 and it will go vertical out of sight. I am really happy with it, especially for the price. In fact I have 3 more coming, they just came in from backorder. I am keeping one and the other 2 are for friends.

I had trouble withe the pushrods binding too. I took a spare wire pushrod and heated with a propane torch and pushed into the plastic guide (not too hot) and remolded the exit. I also used the treaded end to file out the area too. It works pretty good now.

I also, put a great planes 60 size aluminum gear on mine with a plywood backplate glued inside.

Way to go World Models!!! Excellent value....
