What did you use for the spur gear? Mod 1 I assume? I have a hot racing 81t spur and 32t pinion with a 4300kv motor on 3s and hit 70mph, so I'm pretty much topped out unless I throw more voltage at it (have a blx 185 esc so I could go 6s ??) but would rather go to a mod.8 or mod 1 spur and Pinon. Thank you

Mod1. Have used it with and without slipper clutch and works better for me without. Currently using 1:1 gearing with hot racing pinions. 5mm gears will fit right on the trans with no issues. Started with 34t traxxas xo-1 pinion and used it as a spur. Worked great. Was cheap 5$ ish and held up to abuse. But have since changed a lot of ratios to get what I like now. But that's a great beginner Mod1 gear to start. With a 34t mod 1 for spur, I think...not sure I remember...the largest mod one pinion you can use with stock holes in motor plate is 24t or 25t. But if your not scared to cut/dremel it, you can go up to 28t pin on 34t spur..mod 1. This also with the stock plastic motor plate.
Also remeber tire size changes are like gearing changes. Some tires run faster and better.
Also 6s would be over kill. 4s and 5s hard to not break anything. Lol. Also food for though...axial ax-10 trans fit with minor..very minor modding. So that should give you some options on playing also. Plus a dremel is your friend lol.
Take that 81t off and get a spur and pinion closer to 1:1 gearing and you could make that 4300kv do 70 mph on 2s and faster on 3s. Try it for fun. But keep in mind you'll sacrifice something to have something. I was able to break 90mph with a 7700kv castle, 2s, and 58t spur/38t pinion(think that was size) but it would eat spurs and had ok low end and ran hot. But for short time fun..it was awesome. That was years ago lol.
Hope you find a good medium. These are fun and can be setup to do alot of things it shouldn't ?.
