XRAY - Model racing cars

Im going to some competitions this year, and want to take some spares to make sure a breakage doesnt end my day. What bits break most and so i should take as spares?

So for a budget or £30, what would you get? I plan to get a pretty much full set of spares, but cant at the moment hence the budget.

1 pair of C-hubs (different each side)

1 steering knuckle (same both sides)
1 rear upright (same both sides)

Anything left on belts

I agree with Skiddens assessment. But if you are racing outside without any brick walls that your are likely to hit then personally I would go for the belts 1st and in my experience the main belt will generally go before the rear belt.

You have to be unlucky to break one of the aforementioned items, but your belt will wear and snap

Im racing on carpet in april, outdoors in june so i will get skiddins siggestion first and belts before i race outside. Thanks for your help

Do you think it would be worth getting a 2nd hand t2 has alot of parts seem interchangebly with the t4 or are 2nd hand spares no good?

That is a really difficult question. Depends on how abused was the car. Gear train isn't compatible (diffs/solid/belts), so you are better off trying to find a first edition T3.

And even then, the T3 and T4 don't share any carbon fiber part or bulkheads.

Probably not worth it then
