I've been meaning to start a maintenance log of my R/C's so I'll just start with my newest car, a Kraton 8s RTR. I acquired it used in 2022 and my first run on Christmas day wasn't spectacular. It was stock when I bought it and the only thing the previous owner did was install the option speed pinion.

I’ve thought before that a log thread (by rig) could be a super helpful resource. Good to see it, thanks for the info!
I've upgraded the servo from the stock 1/6 scale servo to the Hobbystar HS-6912HV 1/5 scale servo. To upgrade to a 1/5 scale servo, the servo/receiver box was also swapped out to accommodate the wider 1/5 scale servo.

I also replaced the 23T pinion the previous owner installed with a 20T Robinson Racing pinion. The stock pinion this vehicle comes with is a 17T, so I figured 20T would be a happy middle ground between speed and torque.
