motor speed problem

Posted by Julie Macfarlane on January 15, 2011 at 4:04pm

Setup:

Motor smoked and took out the ESC. I bought 4 new motors (hated to wait for shipping from China) and a replacement ESC.

 

3 of 4 motors start to spin as soon as the system is armed.

One though, waits till the throttle is at 50%.

I checked all connections (soldered). If I move that motor to another port, the same thing happens.

 

What can I check?

    Yes, manually calibrate the ESC. Put it in the throttle channel of your Rx, with LiPo out. Tx throttle stick to max, plug in LiPo, wait for the special tone. Lower throttle stick, wait for special tone. Unplug Lipo.
