About 20 years ago, when I was just a kid flying .049 r/c planes, an older freind gave me a Top Flite P-40 built with retracts. The plane was way beyond me at the time and I had no motor or radio that would fly it so it was traded off. Looking back on the plane now, the thing that I remeber the most was the retracts. They were machanical and , of course, rotated but they had some type of motor driven gearbox in the wing's center that was made up of brass gears with a tiller output arm that rotated a torq tube that went outward to each L/G mount. I played with them a little bit while I had it and using a 2-cell battery and some micro switches, got them to work but when I used my radio with the servo just conected to one of the normal channels to operate them, the RF noise of the motor and all those brass gears drove the radio nuts. Never figured out how they were originaly supposed to work or just what make they were. Does this jog anyones memory? I've never ran across this type of retract in all these years and wonder if they were just home built by a very crafty fellow. The friend I got it from didn't fly and said it belonged to an uncle of his, and they both have been gone a long time now. All this time later I'd like to do a P-40 and my first one came to mind and was just wanting to know about those old retracts. Thanks for any info. Mike
