Do you have SEPARATE flaps or are you wanting to use the ailerons as flaperons?

Do you fly mode 1 or 2? I'm expecting mode 2.

Ask Futaba if their T7CAP TX in mode 2 has a 3 position switch and if so which one is it?

If it does not, can/will they modify one for this? I read in manual that "Switch G" (top left) in the mode 1 version is 3 position and also in Helo version.
Let me know their answer. Also go back to post #2 and read manual addendum for additional info. Remember these are examples, you would need to substitute YOUR needs into examples
