When the Good brothers started all this the problem was not too much control but it was too little
. They didn't have self leveling via an electronic control system but it was built into the airframe with high dihedral wings and I don't know what else
Probably a low center of gravity. They just had limited rudder movement, no elevator movement and no ailerons. Why couldn't it be a little bit like that for beginners. The second KL f leveling is misleading but the planes are to hard to fly without it. Are the telecaster and the Blu baby more like the early planes?
