Go to clspeed.com, click on parts finder, and then go to the bottom of the page, and you will find ZZ PROP,s by Mike Hazel. Ask about props for D speed. I am currently running a 8-11 on my modified DD and its the fastest its ever flown. I will post a video soon. Don't buy a prop from John Newton, because his are very rough and unfinished. I went to a control line speed contest in Napa,CA and they said that Mike makes good props so I tried one, and man that is one bad ass prop. There is'nt much thrust a low speed, but once it gets going it just keeps going faster, and faster! BTW these props cost $15-20.00 each. Regards, Scott.
