RE: How Much Flaperon Movement?
Well, I'm sorry I couldn't help you. But, you do have control of master and slave, so if you read your manual very closely, maybe you can figure it out yourself. Another thing to try....
I said to reverse the slave channel. If yours is set up as something like, +100%, then you should change it to -100%. This will do the same thing as reversing a channel. Remember, the master should always be channel 6, because that is flaperons. If the master channel was channel 1, then you would be adjusting ailerons. And if you are adjusting ailerons, if you want to change the right aileron, then the slave would be channel 1 (right aileron). If you wanted to edit the left aileron, the slave channel would be channel 6 (left aileron).
So, good luck. I see what you mean about it being difficult to understand; I hope all you can read this. -Andrew
