RE: New Wild Hare Sukhoi ready to fly
Tom,
I didn't much care for the performance of the 26-10 on my 6.4. It tended to hold down the rpm too much without a gain in thrust to offset.. I ended up doing some expensive experimenting going up the size ladder with Menz and Biela props. I have a hunch you'll end up with a 27 or 28" prop when you get to the sweet spot.
