Thanks for the tips guys.
Where I live it is hard to get a LHS with parts for any touring car that isnt a TL01
One shop has a pro4 in stock, the other can get them (though I would probably buy online)
One has brochures for the Xray.
The australian importer says he has full stock of the xray parts, and said parts supply isnt gonna be a problem.
Yes I have heard that the HPI is hard to get parts for here in Aus, good to see the problem isnt exclusive to Australia though
I have started a list of the pros and cons i have worked out for each car
Though it is by no means complete or conclusive...
As for would I prefer belt or shaft, the durability of a shaft system appeals despite the talk of crunched bevel gears, however the lack of torque steer of the belt is great.
Also the flexibility with battery locations on the Xray is such an advantage.
Would I need to buy aluminuim shock bodies if I got the xray?
