Thrust-Test: Racerstar BR1103B 4500KV (rewound)

By | November 23, 2017

This is the first 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 Racerstar BR1103B that I recently rewound to 4500 KV. I was curious to see how those motors would behave on 3S and on 4S. Will this result in a higher efficiency? Thrust to the moon? — Time to find out!

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.
