graemevw 823 Posted April 1, 2020 What are the options here? Only 2 pinion sizes as stock and the kit uses the smaller one for a silver can! Doesnt give you many options. Plenty of fast blitzers out there though. It will probably stay brushed as i have loads. It will probably get something around 17t, maybe my dynatech 01r. But surely with the stock gearing any modifieds will run hot! Or, is it under geared as stock? Any adjustable options already available? Or, shall i continue thinking about how to cut the gearbox up and make the motor mount adjustable. Thanks. Share this post Link to post Share on other sites
Hobgoblin 1059 Posted April 1, 2020 I've run down to a 12t brushed with a 15t pinion brushed and have put 4000kv brushless through the gearbox without any real motor temp or gearbox issues. I do tend to run in winter in the evenings however This was the blitzer on a basic sport tuned motor, paired with 2s lipo Pretty nippy, even with smaller diameter wheels than stock. I would start off with 17t and see how you like it before you start modifying too much. It might surprise you, I can't see any overheating issues unless you're running back to back to back super high discharge lipo packs through quicksand. 1 Share this post Link to post Share on other sites

I guess im a little wary as i cant run 17t in my terra scorcher due to pinion limitations. Share this post Link to post Share on other sites
Gazzalene 171 Posted April 1, 2020 Very nice BB you have there. Paint job is pukka. I have a BB also and want to run tyres like yours for tarmac use. Can you give info on the tyres please and are they the standard wheels? Thanks Share this post Link to post Share on other sites

I'm running my ST with the stock 13T pinion paired with the sport tuned and now the torque tuned as of yesterday. 1 Share this post Link to post Share on other sites
Hobgoblin 1059 Posted April 1, 2020 I am unsure of what model number it would be as I tend not to run Tamiya pinions. 0.8 mod is the pitch, you should be able to find a generic one fairly easily I am a horrible heathen and run 32dp steel pinions as it's close enough to work and I can get them very easily. https://www.modelsport.co.uk/rw-32-dp-pinion-15-teeth/rc-car-products/13775 Share this post Link to post Share on other sites

Killajb 1546 Posted April 2, 2020 I have a Blitzer Beetle with a black can 20T motor on 2s with the stock pinion. Plenty fast for what I want, and 3s for when it's crazy fun time. On 3s things got a little warm so I added a heatsink to keep it in check. 1 Share this post Link to post Share on other sites
