I am surprised no one has answered these questions yet? No one knows?
The PWM switching rate is a function of duty cycle. Meaning that the higher the freq the more "on" time. And probably the best way to describe it is,
Higher frequency = hotter ESC, cooler motor
Lower frequency = cooler ESC, hotter motor
Motor timing is about as basic as it comes. The lower the pole motor, the lower the timing should be. While anyone can argue their 4 pole Neu runs great at 7 or 10 degrees of timing advance its been my experience that heat increases in the motor as advance does. And if you visit the Neu website for recommended settings you will see that "D" windings should be set with a low advance setting, the "Y" windings should see more timing. Like above 10 degrees.
Yet I run a 1521/ 1.5Y in one of my boats and no matter where I set the advance on my speedo I saw no improvement in speed. Just an increase in motor heat with the increase in timing advance. If your speedo has an automatic timing setting. Stick to that one. I dont know if I really answered your questions but if you want me to go technical in description on motor advance its no different is application of your own cars motor. The result is the same.

Anyone else who can't get their Swordfish 120 to run the UL-1 motor?
I set the throttle travel per instructions and motor won't start - no beep, tunes nothing.
Program Box has been set and is retaining program. Green led stays on.
Trans on, ESC plug in to receiver, connect main power green light comes on then goes out and motor plays tune then 10 beeps and plays tune then 10 beeps and on and on.
3 hours and nothing, I must be missing the oblivious.
Any help out there?Comment

I had the same problem and it was still the throttle end point settings. Hold the throttle full open, plug in power. You will hear 3 beeps then during the next set of beeps, should be 4, move throttle to neutral position. You should now hear 2 beeps and it should be set.Comment

It's not the transmitter trim you're setting it's the controllers sensing of throttle ends. This is from the 240 manual and assumes you do not have built in BEC. If this doesn't work then something is wrong with the controller I would assume. But again, I had the same problem only beeps, rudder controls I believe worked but throttle didn't. Also check out note1 below
B. Pistol style transmitter calibration
- Keep the switch of ESC in ‘OFF’ position. Correctly connect the ESC with brushless motor and battery
pack, plug the receiver lead of ESC into the throttle channel of receiver;
- Use separate receiver battery or UBEC to power receiver.
- Put the throttle to the forward full position, turn on the transmitter;
- Switch ‘ON’ the ESC, there are 3 beeps emitted from the motor, which indicates all electronics are correctly
power on for the setting.
- Then there are 4 long beeps emitted from the motor ♪ ♪ ♪ ♪ .
- Move the throttle stick to the neutral position immediately after any one beep of the 4 long beeps. Two beeps
emitting out indicates calibrating is completed.
- Following two beeps are powering beeps, it is time to go now!
Note: 1)Recommend the ‘0’ position should not be set higher beyond the 50%.
Note: 2) Motor is needed to install for acoustic guide. Meanwhile, please keep the propeller away from human beings or any
objects.Comment

You have both a separate receiver battery AND the power battery hooked up?Mini Cat Racing USA

I'm ready to start fixing my boats again and I'm really interested in the these esc's so a couple of questions will help me in my choices....
1. Will the 240's go in reverse? My pond has narrow ends and sometimes I need reverse, All I do is saw passes from end to end.
2. When will you have them in stock again?OK, You Go First!!!Comment
