Paratoys Thrust Tests

2011-02-10 Coutesty www.Paratoys.com & SkyBiker Aviation

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.
