Hi guys...
I will be buying a Savage 25 SS next month while having my holiday in Hong Kong (RC paradise?).
What are the most essential parts that need replacement/hop upped?
My LHS (HPI dealer) is not doing a good job in stocking Savage parts and it is the only shop that carries HPI parts...

, thus, I will need to get all necessary parts together and bring back home.
So far on my list are
1) heavy duty dog bones x 4
2) hopup brake set
3) Spur gears? size?
4) ???
Thanks in advance.
