Hi adrictan,
are you a drifter, racer or a basher? I believe TT-01D is design for drifting and ball bearings included in the kit.
for racing car
- change your motor mount to aliminum or metal (kit use plastic it will melt easily)
- change your propeller shaft to aluminum if you want to use motor higher than silver can.
- change your pinion to 25 - 55 (TT-01D use 19 - 61)
- use piston with 2 holes (tt-01d indicates 3 holes)
- use zorex tires 40r with medium insert (40r good for sg temp)
- use wheels with 2mm offset
if you have more money to throw for your kit
- a good servo (speed)
- a good servo saver (tamiya stock servo saver suck
)
- steering set
- universal shaft
- carbon upper frame
- stabilizer set
for my opinion TT-01 dont need high end controller dont waste your money on it. Middle end FM controller will do. (again thats for me) But if you are planning to buy a new car dont buy to much bling bling for your TT-01
My suggestion before you buy hop-ups for your kit, visit first our local race track in Quenstown, observe, be freindly ask question to all players and you will learn while having a new freind.
for me TT-05 ( R or IFS) is a better car than TT-01 in terms of everything (durability, speed, etc)
I hope it helps!
