do esc recalibration with your transmitter.... :) :) :) :) :) :) Title: Re: motor not spinning until the stick is moved halfway. Post by: anwar on April 12, 2014, 05:18:50 PM +1
PS: And take a moment to start new topics in the right boards too. Moved. Title: Re: motor not spinning until the stick is moved halfway. Post by: kiran rc on April 12, 2014, 05:48:52 PM Sorry anwar sir. :)
I tried to recalibrate by following steps 1) switched on tx with full throttle 2) pluged in the lipo battery 3) moved the stick slowly back After this it just keeps beeping.the motor doesnt spin at all until the battery is disconnected and connected again.

you see three wires are coming out of the brush less motor 1. one red one is for +ve 2. black one is for - ve 3 third yellow is for the speed of motor ie throttle color coding may very but the method is same. now first two can change the direction of the motor by changing the first two wire problem arrives when the third wire is not placed at the proper spot in the esc i think you have to position the third wire correctly may be problem will solve out. other thing you might help is check our transmitter throttle settings read the calibration process of your esc again maybe some step is missing. :thumbsup: Title: Re: motor not spinning until the stick is moved halfway.

Changing any two connectors changes the direction of spin. @Kiran you have to disconnect the battery after 3rd step and then reconnect it to get it working. But its different for various esc's so which one you are using might help to determine the procedure. Anyways a video to help you out. https://www.youtube.com/watch?v=X0s60U6Y1SE (http://www.youtube.com/watch?v=X0s60U6Y1SE#ws) Title: Re: motor not spinning until the stick is moved halfway.

Title: Re: motor not spinning until the stick is moved halfway. Post by: girishsarwal on April 14, 2014, 11:38:08 AM Please make the following two checks:
1. Not all ESC's have same procedure to calibrate throttle... RTM to see what's the procedure for your ESC brand as correctly suggested by Sachin. 2. You could try plugging into a different channel and try to run the motor. Bear in mind you will need to hold the stick to one side (as the other channels are spring loaded) to initialize the ESC (three beeps or short music). Take off the prop before you do this test. If it works ok with some other channels, and calibration does not work, most likely there is a dead-zone in the transmitter potentiometer. @wingmanbunty While the motor side wires do not have any fixed polarity, the polarity switches and that makes the motor spin; But your premise of one negative, one positive and one signal applies correctly on the thin wires that connect to the rx... BlackRedWhite or BrownRedOrange, in that order Title: Re: motor not spinning until the stick is moved halfway. Post by: kiran rc on April 14, 2014, 12:34:55 PM Thanks sir I will try that. :)
