MP7.5

I used both surfaces on each side as one. The main reason for the Roo2 having two separate control surfaces is to reduce the stress on single servo opting for lesser torque servos plus providing redunancy in case one servo fails.

I installed my Roo2 with two servos on the two surfaces (inboard and outboard) then match them up either mechanically or thru JR MatchBox (MultiBox) and operate them just as single surface like Roo 1.

The instruction manual will recommend you for this configuration and control movements are specified in the manual.
