EMAX MT1804 2480KV Thrust Tests


My other thrust tests:
Going through different motor options to test, I got my hands on the EMAX MT1804 2480KV motors to put on my static thrust jig. Tested GemFan 5030, HQ 5030, HQ 5040, and HQ 6030 in this line of tests. Without further adieu, here are the results:

GemFan 5030 Nylon prop. 345 Grams of static thrust, pulling 7 amps @ WOT.


HQ 5030 Nylon prop. 330 Grams of static thrust, pulling 6 amps @ WOT.


HQ 5040 Nylon prop. 370 Grams of static thrust, pulling 9 amps @ WOT.


HQ 6030 Nylon prop. 410 Grams of static thrust, pulling 8.5 amps @ WOT.


I found it interesting that the HQ 5030 made slightly less thrust than the GemFan 5030, small enough I call it margin of error on the jig, but does so at a full amp less. This is a nice bump in efficiency for longer flight times.

Then comes in the more aggressive props, the HQ 5040 and 6030. The thrust produced and current pulled are in line with that I figured what would happen. Interestingly though, the 6030 uses less current to make more thrust. In theory the 5040 should produce more air speed, but the 6030 will make more lift.

In short, if you're looking for a motor that isn't power hungry to power your reasonably light mini quad, less than 450 grams all up flying weight, these motors give a wide spectrum of efficiency or to be able to make a respectable amount of power. I had intended get these tests done while MultiRotorMinis still had some in stock, but they sold out to quickly for me to keep up. Glad to see the interest in these motors!

I just ordered a set of Sunny Sky X2204S 2300KV motors from BuddyRC, and trying to get my hands on a set of DYS BE1806 2300KV motors as well. Stay tuned for more testing.

Will be very interested to see how these compare.

I have a small fairly light tricopter i was thinking of trying these on when they come back in stock

Cheers

Hi
Great testings
It might be interesting to get als rpm of the prop
Thanks
