Graupner 300s setup
This is my first low wing plane and I have some setup questions. I have tried to balance the plane both upright and inverted and it seems very difficult to balance. It will not balance like my old high wings. I can't quite seem to get it to balance, it just goes from one extreme to another. Also the tank in the kit is fairly small, if I put a bigger tank in how does that affect my balance? Is there any other setup things I should know that are not in the manual?
Thanks
