I've been practicing steering the plane (GWS Beaver) on the ground with the wing off, and I'm having a lot of trouble controlling it.
Are the controls on the transmitter supposed to be that sensitive?
I apply throttle, then try to apply a tiny bit of right rudder, to keep the plane straight. It sometimes works, but most of the time it tends to go too much to the right, so I try to compensate and end up sending the plane along the runway on a zigzag .
Another problem is that a couple of times I've changed throttle by mistake when trying to modify rudder angle.
Any tips on working the sticks? (does it have to be as delicate as performing brain surgery?)
ALSO:
Can the plane have a good takeoff even is it's not taxing in a straight line? (when the time comes, should I just try to put it in the air and go from there? Is it more difficult to control a plane in the air than on the ground?)

Thank You .
