Help with Futaba 8U and mixing Elevator Servos
I have a Funtana 90 which requires two elevator servos. I am using a Futaba 8U computer radio and built a mix from channel 2 to channel 7 to link the two elevators. I figured out how to adjust the end points (ATR), but I am having a problem getting the elevators to move at the same rate inbetween full deflection. Right now if I give halk elevator down there is a difference of about 1/4 inch which of course causes a rolling movement. I thought it might be a difference in exponential, but the 8U only has expo on channels 1-4 so I don;t think that is it. Can someone point me in the right direction?
Thanks in advance for the help.
