Thegreat - I suspect your motor is just fine. Here is what I would try to do.

Re-solder ALL the connectors on your motor, then use bullet type connectors, not alligator clips while the motor is mounted to re-conduct your test.

I suspect you have a poor connection, not a bad motor.

By the way I have found OK hobby to be very responsive and good about helping you out! So even if you do have a bad motor they will work with you to resolve that. I have several of their motors, and really like them!

Mike

The motor did never run, it only tickles but not turns.

I have captured a video about that.


No response from OKHOBBY yet. No costumer service, no support. My money burned

I second this^^^. I had a motor do that. Mine turned out to be a broken wire. The motor wont spin unless it's receiving impulses on all three wire from the ESC. It just rocked back and forth.

Visit my homepage! Have A Good One!

Yes thats what I thought, there is supposed to be a broken wire inside, I also thought a wrong placed magnet can cause this.

Anyway When I measured the cables I found the problem. That is because of thoose high resistance alligator clips. the alligator cables have high resistance and non equal in rezistance. different rezistance should impair synchronicity of the pwm signal.

I didnt have 4mm bullet connectors which motor has 4mm male mounted on. Thats why I used alligator clips. Now I soldered 3,5mm connectors and it worked great. It is rollin'. Powerfull motor.

Hello Nancy, greetings

I have solved the problem thank you. I now wonder why didn't you answer my emails until I write in this forums?

I suggest you to open a key seat for the set screws on the shaft of motors.

WOW! thats rare a hobby shop will admit to QC issues with their motors. hobby king also suffers from QC issues with certain turnigy motors and makes good on replacements every time....now if only they would send a return label for return shipping which often cost 1/2 or more of the total value....lol....,not going to happen.

still....Nancy,thats cool you hunted down "THE GREAT" and showed genuine concern for customer satisfaction...very cool!

nancy,now you know we're here and only flying electric,so please post us when okhobby feels the QC issues are 100% resolved. I'll give infinity a try.

narrow is the place to land...wide is the space to crash....choose the narrow way!
