Use this on my TA05 ver.II R chassis as recommend in the manual. Also bought 24T & 25T as well so I can have more variation depending on the track and motor use.
In combination with the spur gear, the pinion gear makes your car!!! The 22T it's the stock pinion for the TA05 - it comes along with the kit - and it is the best for it!! Either you're drifting or racing it is all you need!!!!
Purchasing this pinion gear set, along with a set of spur gears for your chassis is a great way to improve acceleration or top speed of your RC car. I purchased every pinion gear from 19t to 25t for use in my TT-01, as well as the 55T and 58T spur gears. Using these gears has allowed me to perfect my gear ratio for my style of racing and the motor that I use.
I recommend you also purchase other pinion gear sets just like i did:
Tamiya (#50356) 20T, 21T AV Pinion Gear Set
Tamiya (#50477) 24T, 25T AV Pinion Gear Set
