Hi, need some advise. I have been flying my zoom for some time and everything has worked great until know. I recently purchased a neumotor and am running it on a cc45 which I have used in the past. But since this new neumotor has been in, I can't get the tail to hold anymore. I've replaced everyshaft, running cf blades, tracking good. But today I think I have found the problem, the motor appears to be pulsating. The cc controller is about six months old and everything is running cool. The controller setup is 9.0 v cutoff, insensetive current limiting, Brake disabled, Fixed throttle, Tried all timing modes, Soft cutoff, very soft start, and tried every PWM switching rate. At this point I'm not sure what to try next. The rest of my setup is 4 series 1320 battery, medusa bec, and berg 5 receiver. Any advise would be great. Thanks

I only ask as you did not list this..... have you tried to disable current limiting, if not you should. There is no harm with the esc you are running to do this. Also as a question have you tried your cutoff below 9.0v? If not you should, you are running a very high draw motor and bigger esc, I am to assume you are likely using something bigger than hs50 servos, likely 55 or 56hbs? If so that also with motor, and esc and your config can definetely draw spikes below the 9v cutoff, appearing in air to be pulsating as it will drop below cutoff for a millisecond then "soft start" again.

Hope these things may lead to your answer, according to what you have said you have tried this is all there really is left from a setpoint perspective. Good luck, keep us informed

I have tried the lowest cutoff voltage and disabled current limiting with no help. Also with full collective I noticed it was pulling around 14 amps. I was thinking about trying a cc10 but am not sure if it could handle the amps. I think it would be at its limit if it were to work. Thanks for the help but does anyone know what else might be causing this motor to pulsate.

I run an Neu 1105/3y with a CC25 controller. No issues at all. I run firmware revision 1.11, and would suggest updating your controller to 1.11 (and not 1.12). My CC25 would not even initialize with 1.12, I have been meaning to contact CC to figure out the deal.

Don't use very soft start. It affects the motor ramp up ALL the time, not just at start up. This could be causing your pulsing. Let us know how it goes.

I've actually tried in on soft start (not very soft start) and it still was pulsating. I think I'm going to order a pheonix link to find out what software is on the cc 45 controller. By the way I just put a 1.5 year old pheonix 10 on the motor running it with the medusa bec and 4 series lipoly and it seems to be working great. I just don't know if it can handle the amps. On the watt meter I havent seen anything over 15 amps yet so we will see if this thing will last but I havent had it outside yet. Do you guys think the pheonix 10 can be pushed above 10 amps cont. and surges of 15 amps. The controller is very cool with all the test I have done on it to this point.

I would not even contemplate using a P10, I rekon you problems will be resolved as soon as you change the firmware. to get the 1.12 version software to initialise you simply need to increase the servo travel for the throttle to about 120% to 130 depending on your redio gear.

If you were going to buy another ESC I would make it the CC25

Check out the items I have for sale in the clasifieds including a CSM 420

just flew it with the cc10 and everything went good. I think I will however buy a cc 25 and link. The cc10 worked but I was probably pushing it to its limits.
