brushless RC electric motor thrust test 3cell lipo

I used 11.1v lipo on this test.I managed to get 2.4kg thrust using 4cell lipo battery when fully charged. RPM reading is not accurate as lighting was inadequate

Thanks for sharing!

By the way, is it normal that my brushless motor (25A) cannot be started by normal current of up to 12V without the ESC? I still wait for the speed controller to come in the mail...

The motor just makes a short strong move and stops while buzzing.

good question, I'm not sure but the good thing about brushless motors is actually the ESC!

brushless motors have 3 wires and require an ESC, unlike brushed motors with 2 wires which you can run directly from the power source

whats up with this picture at the beginning

I had this picture in the garage for many years, I like it

is that 1,9 kilograms?

[chardgha]

that's right

Thanks for reply :D!

I think you are right--the three cables are probably used to create some sort of alternating phaze by the ESC. The good part is that i can shift these 3 in any order to change direction according to the propeller.

Haha, yours makes very nice noise: axactly as fuel engine--may-be because its printed in my brain to associate wooden propeller's sound with fuel engine :) you could pull a pretty nice chunk of plane with the 2 kilo pull!
