Well said Matt...
Everything I own is an RTR, but the manuals (HPI) all have exploded view and assembly diagrams. I've had my RS4 Evo, MT2, and my Savage down to the bare deck (or TVPs in the case of the Savy) and it is great feeling getting to know the ins and outs of the R/C, shimming the diffs, rebuilding the shocks, etc. Just take your time, follow the assembly page in your manual, and you can do it yourself! Save some labor money for hop ups and get the satisfaction of doing it yourself!
