Mecam,just wanted to pop in and say thanks for the heads up on the prop and thrust angle.I flew my UCD last weekend and was very dissapointed with the Madien.After reading this thread I changed to an APC 15x4W,and added two washers behind the left motor mount,and what a difference,it's like two different planes.I had damn near everyone either flying it or at least wanting to fly it,I probablly sold 3 of em for the LHS today!!LOL,anyway,thanks
Mike
