JPX engine i have two data points:
75 lbs thrust, 34"dia 20"pitch prop at 4250rpm
90 lbs thrust , 40"dia 17" pitch prop at 3550rpm
all direct drive, more results to follow.
Test Method:
We have a test stand with a free rolling section the nacelle mounts to. the only thing the engine is pulling is itself and about 5 pounds of steel, attached to a 150lb linear spring scale.

Can anyone report on thrust numbers for the rotax 185? Discribe prop used and if redrives or not? How thrust was measured? i.e. feed scale atc.
