Can the spoilers be set up with two servos as you would ailerons? Then have the linkages go straight to the spoiler like an aileron would? What kind of Y-harness would you use for the two-servo setup to have the servo go the same way, instead of opposite like ailerons.

Flaps can be setup with two servos so why couldnt spoilers be hooked up the same way as flaps?

Spoiler installation photos and graphics would be great.
