Programmable ESC and Motor Timing?
My motor is a Reedy Sonic 540 Mach2 17.5T
My ESC is an X-Car 120a, the clone of a Hobbywing Xerun, so much so that the operating manual for the X-Car is a Hobbywing link.
Wondering about timing. The motor timing cap has a range from 0-40 on it and it comes factory preset at 20. First of all I find it a bit odd that it's not at 0....isn't it?
But assuming that's how Reedy wants it, I'm wondering about programmable timing in my ESC. Here's a screen shot of the programmable features. Note that in BLUE is the default settings, of which, timing is 15.
Am I at 35 degrees timing if the motor is at 20 and the ESC is at 15? Do you think I should zero this out on the ESC??? I bought the USB programmer.
Also please let me know what I should do about Low Voltage Cut-Off. I have these batteries. Note that they are 2S2P, if that makes a difference? THANKS

Re: Programmable ESC and Motor Timing?
I suggest starting with the factory defaults and tuning from there.
. . . you have Associated Green Slime for brains. And not even new Green Slime, but old gooped out Green Slime.

Okay sounds good.85Edinger wrote:I suggest starting with the factory defaults and tuning from there.
My concern is too much advanced timing though, not wanting to increase it more. Is it common that ESC's and motors come already advanced beyond 0?
Oh and voltage cut-off....3.0V isn't too low?

Re: Programmable ESC and Motor Timing?
Most guys that race blinky classes max the motor timing. If it's like a hobbywing you can add a total of 64 degrees of timing, either by boost timing and or a mix of turbo timing. Boost timing increases power/speed till full throttle, turbo timing takes the motor beyond full throttle. Those settings don't show dynamic timing, do you know if the ESC has it or can be updated.
Factory motor settings are a good start, with dynamic timing you can do anything really, the results can be pretty impressive but keep an eye on esc/motor temps as they are the limiting factor.
Those batteries are pretty good and you'll want to set the cutoff to a minimun of 3.0v cell, 3.2v is a safer more conservative setting.
