TT02 pinion gear questions

[EmJayeX]

Hello! 

So Ive been told the pinion gear on tamiya kits are made of soft aluminum. My TT02 kit has yet to arrive. I was starting to look into buying another pinion and then came across an older thread...someone said this....

 

"The TT-02 comes with a sturdy steel pinion right from the start, unlike other Tamiya kits where an aluminum pinion is supplies."

Is this true for TT02s? 

Im trying to build my TT02 (my first rc kit, ever) on a budget and dont want to spend too much on upgrades, repairs, etc. 

Any insight is much appreciated!
