RE: Diamond dust with turbax fan unit??
IFLY,
I already have a DD with OS 46 vx-df with 7x8 prop, i had thought it would be as fast or faster.. i was only yhinking of doing so cuz apc has discontinued the 7.4x8.25 carbon prop.. anyhow i guess ill have to put this idea on hold. i cant give up any speed!!! 130mph is hard to say no to..
