Instead of trying to control twin rudders which is problematical (makes for a tail heavy situation) Jim used ailerons . A great solution for RC electric. And ailerons are legal for SAM competition. When we flew it, it seemed nose heavy or perhaps there's not enough decalage. Jim will make some adjustments and fly it again.
