This talk of holding a TX, and which fingers do the work started me thinking back to my early days in this hobby. I built my first radio. A Heathkit. They had just come on the market and Heath sold them in kit form you assembled yourself. I had never handled a soldering iron, or done anything remotely related to electronic assembly, but I sent in my money and plunged in. It was a snap thanks to Heath's methods. The TX, RX and 4 servos worked right off and did so for many years. There were two types of TXs. A square 4 channel and a vertical 3 channel. I got the vertical type. It was shapedn sort of like an old military 'Walkie Talkie" radio. It was a 3 channel, single stick, but I got the 4 channel conversion. This was a control pot inside a knob placed atop the aileron/rudder stick. After assembly, the knob was the rudder, the stick then was aileron and elevator. Throttle was a lever, like a trim lever. Up was High throttle, down was Low. It was on the right side of the case. Slipping my hand through an elastic stap on the case back the TX sat in the palm of my left hand with the middle finger of my hand falling on the throttle lever on the right side. The strap kept me from dropping the TX. It was all very comfortable. I'd set the heel of my right hand on the case front just below the stick, put my thumb and second finger on the knob and fly! It was a great system. I still have the case and am planning to put the guts of a Futaba 4 ch. inside. Just have to get the correct pot for the rudder. Funny thing, after learning to fly on that single stick and becoming proficient enough to help other newbies I then had to learn to fly a two stick, which is what all the other guys had! I have another single stick radio I fly once in a while, and when I do everyone stops to watch.
