Hi, I got a Xerun 4268 Sd G2. The bearing is getting really bad now. Is there any proper way to remove the bearing? Especially at the sensor end bell.

I did read somewhere (I forget where) someone tried to remove the large bearing in the bell but somehow destroyed the bearing and the outer race stucked inside. So is there any preparation (eg: pre-heat) I should do before push the bearing out?

Hello, I just purchased 3 Hobbywing XR10 Pros. I installed 1 in my stadium truck and the other two are still in the box. When I power on the esc the rear tires click forward. I ran the truck this past weekend and it seemed to run fine, I am just curious about this little click forward when I turn the esc on.
Can someone tell me whether this is normal or not. The only thing I can compare it to would be when you put a dirt bike into 1st gear from neutral.

Just to confirm, the transmitter is already turned on first, correct?

It sounds like your receiver needs to have the "fail safe" mode calibrated. I would check the manual for your radio on how to set the fail safe operation. I bet you're getting a dirty signal on the radio going into the ESC causing it to blip. With the car held safely in the air, when you turn the transmitter off (leaving the car on), does it cause the throttle to run away?

how about turning on ESC with the Rx unplugged?

This happens to both my xr8 sct and quicrun 150amp... The beeps indicating how many cell it runs on... In my case it is a 4s lipo, so it beeps 4x and the wheel wiggle forward a little on every beep... However, for xr8 sct, the wheels wiggle depends on my gearing... usually the wheel wiggle at the first beep only.

Well I plugged it into the wifi module uploaded the "mod buggy" profile and it eliminated the little wheel click when I power on the esc.

Also consider disabling "Hybrid" mode which I think is the default setting, I have had problems with a slight delay which is problematic for heads up starts. I run full sensored mode without any delay from a dead stop on the line.

I ran the esc fine without calibrating it. When I calibrated it the car gets stuck in wot. I have epa and trim set properly. I tried forward and reverse throttle settings. The radio is a sanwa super exzes, same as an airtronics m8.

That doesn't make sense. Hybrid mode will run sensored from a dead stop. It only switches to sensorless at high speed.

What is the front and rear bearing size (or standard bearing code) for the XERUN 4268-G2 and 4274-G2 motors?
This information isn't in the datasheet / pdf.

Did you calibrate the speedo to the radio properly?

Sounds like when you calibrated it you started with full throttle setting and not neutral. Make sure you calibrate it in the right order....1=neutral
2=Full throttle
3=Full brakes

So my dumbass just reversed the plugs on my new esc. There was a spark a puff of smoke and the battery cables got pretty hot. I put them in propeely and proceeded to run my race with no problems. Did I get lucky or did anything get compromised? Hopefully its the battery and not the esc.
