Is that a DLE-55? If so what size props do they recommend? Xoar, NX, JXF, or VESS. All very good props. The best prop for your money has to be a JXF. Call Tom at ValleyViewRc. He can drill it for you at no extra charge. I'm running a 27X10 on my DA-100. Great props and there cheap. Tom does a great job drilling them also. Just tell him how you want it drilled.
