716 Brushed Motor Thrust Testing. BetaFPV, Flight-Sky & GnarlyFPV


Review, Videos / Wednesday, December 20th, 2017

today’s video I will be doing some very crude motor and prop trust testing. In this video I will be pitting the BetaFPV, Flight-Sky and GnarlyFPV 716 brushed motors. In this test I used my homemade rig which consists of the motor mounts and ducts from a Beta 75 and a Beta 65s frame. I used standard 4 blade props for this test. Each test I used a fully charged LIHV 260mah BetaFPV battery. The motor was then cranked up to max in BetaFlight for a few seconds and the sustained pressure was measured.

The results were the following

BetaFPV – 8.4grams
Flight-Sky – 7.9grams
GnarlyFPV – 9.3grams

Here are the specs for each and where you can get them.
