| I'm flying the 8.73 ratio at a head speed of 2050. This gets the Hyper above its power peak so that torque will increase as the blade loads up. Currently flying with Radix 600s and it flies great. I get very soggy performance at 1850 rpm (IU1).
The next step is to fit 620s - then I expect better performance. We need extra lift flying at 4600'.
