TR02V2

[The Joker]

Hi All,
I have decided to buy a TR02V2 to replace my BSR BZ-222 as I am fed up with not being able to get any spares for it.
Looking at both the TR manual and TC evo manual the parts look like they are interchangeable, is this true?
As I replace/break or upgrade parts can I use the evo parts as upgrades i.e front C's and hubs?
Another thing I have noticed is that they share the same chassis, does this mean that the evo bodyshell will fit?
I currently run with a 6000mah Turnigy 2S hard pack, will this fit ok in the TR02V2?

Sorry about all of the questions but I got the BZ-222 to get back into racing after a 15 year break and so far it has spent most of its life on the bench waiting for parts from HK! I do like the Belt tranny though.
