Default Justock 17.5.

Im new to the race seen. I'm racing in a slash stock carpet oval class. We are allowed a 17.5 Motor in blinky mode. I hear alot about timing advance on sencored brushless motors. I have a XR10 ESC and mutifunction LCD program box. I need info on where to plug in the box to the ESC. Or is this ESC unprogramable and it is what it is. How can I advance the timing on a Justock 17.5 sensored motor.

For the ESC the wire that goes to the receiver is used to connect to the program box. If using the Justock ESC you will not be able to advance timing but will have punch control and some basic brake functions to change. If you also have the Justock motor that I'm thinking of there is no way to adjust timing. They are fixed timing. At least mine is.

People are adjusting the timing on the motor itself, your just stock motor has fixed timing. There is actually quite a bit of power you are giving up by not advancing your timing.

But be careful doing this. Too much timing and you will burn your motor up. Your best bet is to get a motor analyzer for about 100 bucks, then tune the timing using it. I usually run all my motors to pull around 6-6.5amps. I always adjust by amps rather than timing numbers since all motors vary

Ya the Justock is fixed timing, which is blinky mode. But the timing can be changed on your actual motor. There should be a slider on the can that you can see where it is set at, by number. That is something I have not messed with, as I am also somewhat of a noob at 17.5 buggy. So I need to research when/how much to adjust on that.

The just stock 17.5 is a fixed timing motor, there is no timing adjustment .

Oh ya, that is right. I misread. I was thinking of my motor, which is a Fantom. But ya along with the Justock ESC (which is fixed) I didn't realize that the XR10 Justock motor was a fixed motor. Good catch.
