How to convert an RC bike with a brushless motor

Well I've converted one of these rc bikes into a snarling (ha ha) nitro powered machine. I'm now going to convert my other stock model into a brushless monster. This particular bike had a rather bumpy crossing from the USA when I bought it from ebay. It got damaged in it's box and was returned to the sender. He, very nicely, found a new set of front forks, fitted them and posted it back to me, for no extra charge! Top Man! It's a bit sluggish, stock, so I think sticking a MAMBA MAX 7700kv motor up it's jacksey, should give it the shot in the arm I so richley deserve! Here's to some fast and furious offroad fun over the summer!
