Thrust-Test: Brotherhobby Returner R3 1106 5100KV

By | December 7, 2017

This is the fifth benchmark in a series of 110x motor thrust tests I will be doing in the next few weeks. You can read more about the background of those tests in my overview post.

This time I will be testing the Brotherhobby Returner R3 1106 5100KV. As usual the first test this motor has to pass is a quick check of the KV rating. This motor was measured to have 4925 KV.

Please note that the FuriousFPV propeller is missing in this test, it’s still in transit. I will update the charts once it arrives.

Conclusions

I will draw my conclusions once my thrust tests are all done. I will update this post once I finished all my tests.

    NIce testing, this motor is however more suitable for larger (2.5″ or even low pitch 3″) props. Would have been great to see results for those (especially gemfan 2540) as well
