These spur gears are an excellent purchase for the TT01. By having two different tooth counts it is possible to experiment with different gear ratios. For rally purposes I prefer the 58 tooth(larger) spur gear, and for high speed tarmac runs I prefer the smaller 56 tooth spur. I would strongly recommend purchasing after market pinions opposed to keeping the stock Tamiya pinions when used with these spurs. All in all this is a very good purchase for any TT01 owner.
This is the cheapest TT-01 upgrade to increase speed tremendously. I test run my TT-01 gear ratio setting (5.72:1) by installing the 58T pairing with 25T pinion gear on TAMIYA Sport Tuned Motor. Note that I am using TAMIYA semi slick tires set and full ball bearings on my TT-01. After the test run I have notice sacrificed acceleration but have high top end speed. My TT-01 runs very fast compared to stock gearing. The TT-01 sounds much quieter due to heavy motor loading and I can hear my TT-01 'cutting the wind' as it passes by me. The sound I described is very cool. I recommended this upgrade for long car park bashing or racing at large circuit.
one of the cheapest mods you can do to make your standard EP brush motor car go faster without changing the motor to brushless. I just installed it in my tt01d which has a rs540 sport tuned motor, easy to install and a very noticeable difference in speed. not recommended for standard tamiya silver can motor.
The Tamiya Spur and Pinion gears are a great way to get a little extra top speed out of your RC car. Buying this spur gear set gives you accesibility to many different gear ratios. Experimenting with different combinations will allow you to experiment and find the ratio which best suits your style of racing! A must have for any TT01 owner.
Good upgrade for the TT-01 chassis
It helps make the car accelerate faster when combined
with the Tamiya pinion gear found on these website.
Definitely an upgrade when trying to make the car accelerate faster
I am usig it on my TT-01D and believe me it makes the car drift
a lot better than the stock
