If there is one thing I have learned when it comes to R/C, its to give spares a thought before you purchase your new vehicle.
I know look at the avaliability of spares before making a purchase and pick up a few of the most common bits to break while I can get hold of them.
Its very easy to fall into the trap of buying a (often discontinued) model that is reduced in a store, only to find you break it in 5 minutes and can not get hold of the parts.
The first thing I did after picking up my Blade 120 SR from model zone is buy a load of spares from rsbspares.com
If you are wondering what the blade 120 SR is then watch this.
