Hi all, Just thought I would share this with everyone.
If you are using a KR timer the Hobby King G25 motors will not work. Turns out there isn't enough poles for the timer to function properly. I tried both KV motors and got the same result. Just a heads up all.

What are the symptoms?  Have you tried a servo tester in place of the KR timer to see if it is the speed controller not the timer that the G25 doesn't like?

Hobby king sells many different types and they are cheep.  Every electric flight bag should have one.

The neat thing is that if you are testing a speed controller the speed controller supplies the power for the tester. For testing servos you need an external power source.

Thanks for the heads up.  I looked at the HobbyKing web sight and unfortunately they do not list the number of poles.   Looking at several of their motors I don't see any data on number of poles.    In the moderately priced motors I have had good luck with Cobra motors.

these are the 2 motors that I have been using this past season.

Both of them work very nicely with the KR and the Hubin timers.

I rum them both on 4S packs.

Maybe look in the front of the motor and count them? Not rocket brain surgery, after all.
