I'm a thumber, have been all my life. Pops did it that way, so I learned that way. The one thing that people really think I"m crazy with is my springs. I would take them out if I wanted to mess with the radio, but don't want to bother. I feel that you should be able to get to a point where you and the plane are one and you think and the plane does. With no springs I feel I get more of that. Most of my friends when they fly one of my planes, the first thing they notice is that it's out of trim, and I say really, never noticed, because I ALWAYS fly the plane. Some my think that crazy, but I couldn't care less about the sticks, they are just the means to an end. My brain waves control the aiplane, not the sticks. But yeah I use my thumbs.
