Thrust tests are one data point for comparing the thrust of motors.
On two different days you'll get different results, probably up to 10%.
Plus, some manufacturers may use different props than the machines are
sold with (i.e. using bigger props with smaller cage clearances
for the thrust test).
But this is a good starting point to compare claims. Thrust is the
ultimate test for paramotor pilots whereas horsepower is what engine
makers live by. A high horsepower motor mated to the wrong prop/redrive
will may still be a low power machine.
Thanks to Mike Robinson of Paratoys for providing the thrust test
equipment and Wayne Mitchler for recording and providing the data.
Testing was performed at the Salton Sea, CA at an elevation of -50 feet,
near 30.00 inches of barometric pressure, and 65 degrees F.
