Allan Bennett Posted January 17, 2016 Share Posted January 17, 2016 Is your battery fully charged? Pulsing up and down, with some brands of ESC, means it's warning you the battery is low and it's time to land. Are you using the stock battery and propellor?

Pete B Posted January 17, 2016 Share Posted January 17, 2016 Might be worth teaching the ESC the throttle range again. Just ask if you need to know how.... Pete Quote Link to comment Share on other sites More sharing options...
tommy Posted January 17, 2016 Author Share Posted January 17, 2016 Hi could you run through it for me to make sure I am doing it properly thanks Pete Quote Link to comment Share on other sites More sharing options...
Pete B Posted January 18, 2016 Share Posted January 18, 2016 Normal procedure is: Firstly, remove the prop! You don't want any unpleasant surprises...... Switch on the Tx and move the throttle to fully on (up). Reset your throttle trim to the mid-point setting if you've moved it to the lowest point. Next, connect the battery pack for the model. You should hear some beeping from the motor. Move the throttle stick to fully off (down). There should be a confirmatory beep and you should have all controls operating. You have just calibrated the ESC to know the range of the throttle for your Tx. It should only need to be done once unless you change anything. Only replace the prop when you've finished setting it up, for safety reasons Pete Quote Link to comment Share on other sites More sharing options...
