hi and welcome thundertim,
First of all, the only extra parts you`ll need, if you havent already got them is a glo start, fuel and AA batteries. these are available at model shops.
i`m not clued up on the running sides of these particular trucks but thunder tiger do seem to be quite good quality wise, you`ll only need to replace the parts you break.,which you will

.
a good easy to use onlione website is modelsport,
www.modelsport.co.uk
these guys are very professional and very prompt delivery, please note we are not affiliated with modelsport in any way , just a very easy to use website, and a cracking shop !
any more queries tim, just post them here
p.s , do read and understand the instructions on running in, if your not sure , just post
cheers
