I just got back into 10th scale racing since my town finally has a track. Been out of the hobby for 10 years so feel like a newb again. I just assembled a Team AE B7 and I'm using a HW xerun xr10 stock spec g2 with a 21.5 motor and flysky transmitter and receiver. It seems like I have to give the car way more throttle to get the tires to start turning than what I remember. My transmitter is showing 20% throttle before the tires start spinning even sitting on a stand. Does this seem right? Once the tires start spinning it's like the drivetrain is out of balance as tires fluctuate in speed. What should I start looking at? Thanks for any help.

That ESC by default has a very small initial throttle setting. Use the programmer to turn it up.

The motor has a lower sensor port and is where my sensor wire is plugged in. Hard to see on the video I posted. Should I be using the top port instead?

Thank you for the soldering tips and recommendations. I'm definitely rusty on my soldering skills with my lapse in being in the hobby

Definitely recommend the pinned post on soldering at the top of this sub forum. A real treasure of knowledge
.

Just wanted to come back and update this thread. I appreciate everyone's input and help. Swapped out to a different sensor wire and used the programmer to help tune the throttle. As for the variation and out-of-round tire rotation; I ended up flipping on side of my diff height inserts which was causing the rear diff to be misaligned. Solved my issue.
