IAN Bargh Posted February 28, 2023 Share Posted February 28, 2023 Can anyone throw any light on this electrical problem please. If I increase the throttle gradually then it runs up to normal speed no problem but if I push the throttle stick straight up to full power then the motor pulses from high revs to low revs continually. Thanks,,Ian. Quote Link to comment Share on other sites More sharing options...
Shaun Walsh Posted February 28, 2023 Share Posted February 28, 2023 The battery can't supply enough power so the voltage drops to the point where the esc pulses the throttle to warn you of low voltage. Try a high c rated battery or your battery may be old and have degraded. Quote Link to comment Share on other sites More sharing options...
IAN Bargh Posted March 1, 2023 Author Share Posted March 1, 2023 Hi Shaun and thanks for reply. Tried it with all my 3 cells some above rating but it does it with them all. Could it be a esc fault. Im only just starting with electric power. Quote Link to comment Share on other sites More sharing options...
IAN Bargh Posted March 1, 2023 Author Share Posted March 1, 2023 The other point ,,, it does it right from the start with freshly charged batteries. Quote Link to comment Share on other sites More sharing options...
Shaun Walsh Posted March 2, 2023 Share Posted March 2, 2023 Is it this model? https://hobbyking.com/en_us/a-1-skyraider-1600mm-w-retracts-flaps-air-brakes-pnf.html?___store=en_us or this one? https://hobbyking.com/en_us/h-king-a-1-skyraider-pnf-w-orx-flight-stabilizer-800mm-31-5.html Quote Link to comment Share on other sites More sharing options...
Geoff S Posted March 2, 2023 Share Posted March 2, 2023 How much current are you drawing? If you don't have a so-called Wattmeter then it's advisable to get one if you intend to fly a lot of electrically powered models - they're not particularly expensive now and often have a battery checking mode which is also useful (essential to me) Quote Link to comment Share on other sites More sharing options...
IAN Bargh Posted March 2, 2023 Author Share Posted March 2, 2023 The smaller one Shaun but without flight stabilisation. I'd have buy one Geoff but as you say : Quote Link to comment Share on other sites More sharing options...
IAN Bargh Posted March 2, 2023 Author Share Posted March 2, 2023 Just a point gents,, its not always had the problem its started just recently.🛬 Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted March 2, 2023 Share Posted March 2, 2023 You are waiting for the wattmeter Ian, which will reveal most problems The following assumes the battery and it's connections and sockets are serviceable and charged, and you tried 3. But for this to be recent, may be the motor connections need looking at and The soldering. The ESC gets its information from the motor, and the motor or your throttle stick tells the ESC to reduce or increase revs. Your throttle is not being reduced, so the motor must be communicating the reduced throttle.
