Thanks for the info Jonny.

Also contrary to my previous statement it appears my parents are prepared to shell out a bit more money after i did so well in my maths GCSE :wink: So my question to you is this: Which reliable ESC should i go for? The cheap Hong Kong ones look tempting but if a Sabertooth or similar is available then that would be better, preferably under or around £60. Anyone got a recommendation/supplier?
Thanks again
