Bratwurst defiantly has a point. I thrust tested one of the original prototype OpenPPG x4 paramotors a while back and only got 80lb thrust. Granted the motors are different than the current ones, I was only running 12s(not 14s), the batteries were old and sagging out, I am at a high elevation, and I was running the wrong props. But still, 40lb thrust for any period of time with a 22 inch prop is a bit insane. I build and fly racing drones so I know its not completely impossible, but I doubt the ability of an x4 to reach the specs listed
According to the manufacture the m10 motor, which the x4 uses, with the 180kv version,22x10 prop, and at 48v, you can get a peak of 15.5kg thrust or 34 pounds of thrust for a total of 136lb thrust. Chances are these numbers are stretched and were done in optimal conditions, so I would expect lower numbers than this with a full battery at 12s.
So basically on 12s don’t expect anything close to the rated thrust of the x4. You may be able to get closer with a 14s setup, but I have doubts that 160 pounds of thrust is reachable. Yet even with all this, I still believe that the openppg produces way more thrust than a Minne paramotor.
I would love to hear your input on this Paul.
