This is the third 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 6000 KV. Well, actually I planned to rewind it to ~6500KV but it turned out having 6000KV. I was curious to see how those BR1103B 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.

For now you can find all my 110x thrust tests in this link list:

    Hi!
    I just saw that you have some experience in re-winding those motors to lower kv values.
    I would like to build a really small gimbal to just support the runcam split, and i would like to use 110X motors for this. Unfortunately high kv is impracical for using as a gimbal motor.
    What do you think to what minimum range such a motor can be rewound to and still be able to support such a small camera?
    Best regards!
