Thanks, Piper Chuck. I was afraid that was the case, but I was hoping against hope that it wasn't. Guess I will have to procure a Futaba PPM receiver to do this or fix the Futaba transmitter. It is an early version of PCM and computer technology that has adjustable travel feature, but I haven't figured out how to adjust it. Everything works except left aileron. It only travels about 1/8 inch and I have not yet figured out how to adjust the travel. Right aileron seems to have plenty of travel, and another servo does the same thing, so it isn't a servo problem. Has to be either transmitter or receiver problem, and I'm guessing transmitter. Could be using it soon as a boat anchor. [&o]
