HI MATCHLESS! I need to tell you that there aren't any store bought props that work with the diesel 061 in a hover. The 7-3 APC is too much, the throttle response is not soon enough, and when it does come on, you zoom up. I lucked into a few 7-2 props made out of a light wood, similar to basswood. The WIDE blades scoop lots of air at the low rpms. I think making a mold of this wood prop is the thing to do, and make the blades wafer thin out of fiberglass, like an electric prop. You know, come to think of it, I haven't looked at the commercial electric props yet. I promise to put together a "cleaned up" version of the HALFWIT for your album, so you can delete that wrinkled, oily rag I showed you
! Another down side to diesel, it infiltrates every nook and cranny on the plane, so you have to be way more meticulous than I am about fuel proofing.
