Im just a little bit ahead of chicken farmer for the cub because just a few days ago I was given a already built one that is 2nd hand.. 105" wing span. I am going to get a gas 30cc engine for it and have already setup all the servos. I just need that engine.

All I suggest is learn to fly with rudder and elevator only on a trainer, that way you should be good to go for the cub.. but don't blame me if you crash it because I havent flown mine yet to tell ya what its like.

If you plan on putting it on floats like I am the rudder practice helps too. I put my Sig LT-40 on floats and it works good but you need to have a little experiance with rudder especially on take off or you will have to get in the boat and get it heh.
