Help electronics on SLOW STICK ??
This one is easy, you just have the speed control plugged into the wrong channel. Unplug everything, then take your rudder servo plug, and plug it in each port on the Rx until you find the one that runs the rudder with the stick you want-(left or right, depending on your prefference). Do the same with the servo for the elevator, until it's working when you wiggle the right stick up and down, (fore and aft?) finally plug in your speed controller 'til you find it operating on the throttle stick.
