Thanks for the input folks. He’s having a great time so far.
We have watched a lot of race videos and been to three different tracks so far. We are even tracking lap times of others to see how he compares. We are about 2-5 seconds off podium pace at each track, but he’s still working on using the brake to slow down instead of just cruising into the corners.
We did make some changes to the setup so the kart. It was pushing pretty bad and now it might be a touch loose. My biggest complaint about him so far (not really a complaint I’m honestly happy about it.) is that he reduces speed down to whatever the kart will provide and it makes it hard to judge what’s happening or needs adjusted. I ask him what the kart is doing or if he needs anything changed and he just says "Don’t touch it, it’s perfect. (Freaking drivers.) I think we have a fairly decent learning platform for him right now so I’ll follow the advice and leave it alone for now.
He’s been on track with several other karts and does better when he has a rabbit to chase or when he’s being chased.
My thoughts on his development are that there is nothing I can say or do now to make him a great driver and carry that on with him. I can however say or do something now that will cause him to quit or give it up.
Thanks again, and I’ll keep looking reading and staying positive.
