For the last year I have been flying a GP Escapade with a Magnum .46 XLS using an APC 11x6 prop right from the beginning and it has worked great. I also have the remote needle valve set up without any problems. I am running the engine slightly rich and getting about 12000 rpm with no idling or midrange problems and no dead sticks. The 11x6 gives both good speed and vertical performance. There is no slop in the needle valve. The low speed needle valve never has needed to be adjusted. The 10x6 is too little for that engine and is more appropriate for a .40 size bushed engine. You will love the combination when you get it set the way you want.
