H2 hybrid

[Sturdy]

Hello

I recently treated myself to one of these little beauty's but I have been reading mixed threads on what to change and who's parts fit what.
I was wondering if anyone has a list of the main parts that are best exchanged for the ones that come with the pro kit? Ie losi rear hubs etc

Just so I can go buy the parts and swap before I start racing next month.

Many thanks

Ps. This car is a bargain!
