Agreed he'll be turning some high RPMs. As I said, it's (after doing some math) about 83% of the minimum recommended load for that engine. A better way (in my experience) to calculate what fits for pitch/diameter is to take dia*dia*dia*dia*pitch (i.e. dia to the 4th power and multiply by pitch). This gives you a rough ''loading'' number. ............................

Here's a sample for the DLE-20:

14 10 384160
16 6 393216
15 8 405000
14 11 422576
16 7 458752
14 12 460992
17 6 501126
15 10 506250
16 8 524288
Nice chart, but, does it take into consideration; H.P., torque, rpm, temperature, etc., etc???
The mathematics are cool, but go back and listen to the video of his DLE20 in flight, it's screaming as it passes by!
