So im looking into building a crawler... and ive put together a list of things i THINK i will need (minus electrics)

Here goes...

3racing axial gearbox (green)
Proline "tuber" cage and shell bits
Losi 3 piece wheels
Tyres (NO IDEA WHICH ONES)
3racing CR01 oil dampers
Venom heatsink motor + transmission mount (for AX10)
Axial high clearance linkage set

1 problem though.... I HAVE NO IDEA WHICH AXLES TO GET ...

any help will be much appreciated
