I just bought a DP Ultimate. I'm putting 4 MPX Royal Digi servos in the wings and JR 8411s on the elevator and rudder. Throttle will be a 425 or 517, whatever is at hand.

I'd heard that the u/c on this plane is a little on the tentative side, so I picked up a set of CF gear from Troybuiltmodels.com. Nice and light, with no flex.
