thanks for the reply, I think I have an idea now with the two servos on the ailerons using "Y" harness and that they need to move in opposite direction....I'll mess with the "flaperons" later.
with balancing the blades, with a heli main rotor blades we just add tracking tape to add weight to the lighter blade...FYI..
Having two aileron servos on individual channels does NOT REQUIRE flapperon settings. That is just something it will enable as well as other things.
If you have at least 5 channels on your receiver, you can put the ailerons on separate channels. Now you can fine tune each aileron from the radio, reverse one servo, etc. I would set it up this way for convenience. And, in the future if you want to use some of the special features of the Futaba 9C ( I have the same radio) you will be good to go.
A Y cable, if you have a 5 channel receiver, is just an unneeded expense that adds weight and requires you to mount the servos in such a way that you won't have to reverse one.
Put them on separate channels. The manual tells you how to do this.
