Sounds like the wrong tire, and the left rear wheel is binding.
whenever I use the stock gear differential, I remove the rear left wheel with the small black adapter to key on the axle. I sand it lightly where the adapter would touch the bearing, then check the fit. I stop when I can see just a little play back and forth of the axle when the wheel is fully pushed on the axle.
this allows you to tighten the left rear wheel completely and remove slop from having a loose nut holding it in place. Improves consistency and speed by reducing the possibility of drag on the axle.
I also apply some grease inside of the differential as suggested above. Light grease can make a huge difference in the smoothness of the car and the differential unloading abruptly over any bumps. With this done, the stock differential can perform very well and even rival a ball differential in stock motor classes.

I have a diff with Kyosho 3k, 15k, and 30k for different conditions. 30k is really for loose carpet, but works ok on RCP. I prefer the 3k for tight tracks, and the 15k for flowing medium or higher speed tracks.
I used a clean diff in my last race in Brooklyn, and it wasnt bad, I had 30k in the diff that was in there which was last run on high speed carpet and it proved to be too stiff for the tight 7x15 tile layout in Brooklyn (lane width is about 1-1.5 tiles through the track, track is basically all expansion tiles with borders screwed through it). I would have preferred 3k in the diff, but didnt have time to do it. Even petroleum jelly works really well as a solution for disc damper and differentials.

Just finished up installing a PN Racing DSM2 board in my buds MR 03. Got rid of his glitchy stock TX and bound to his DX4C. Track time should be a bit better tomorrow!

I’m pretty sure this is the best round of driving I’ve done yet.

Nice going Billy. You are still running the GT3 correct?
I was on Banzai at lunch, they seem to have gotten a Kyosho shipment in and have some new white bodies in stock that are not easy to get. I was tempted to order a couple more but I still have not totally finished the 360GTC or the F40 and still have the Porsche GT1 and Stratos to start on.....
Cheers,
Jim

I didn't find it overly hard, proper supplys and tools are required. I used a lighted magnifying glass because it is quite small.
His car ran great for him tonight no twitching and he was able to focus on tuning expo on steering to soften it up down the straight. He said the throttle had a much different feel but was getting used to the increased drag break, and I thought it felt soft on the trigger from 25% to 75%. It did run very well and he was stoked at only having to spend ~$100 when he was expecting to have spend $230-$250ish for a comparable fhss TX.
