Not finished it yet because we've not even been looking at the robots over the summer and suddenly realised this weekend we had two heavies to get ready for portsmouth.

He can also find some useful projects here

All very useful and quite a bit of programming information if you take a look round it

but yes, you can either learn how to drive upside down or you could also extend the channel direction switch on your tx so it's easily accessible for you to use as a flip switch. How easy that is depends on the tx but it's really not that hard on most of them. It does invalidate the warranty though

Sorry if this sounds like a silly question but what is that? is it (first link) a ESC? sorry i dont know electronics but looks like all the code is there. if so how much current can it take? or is that down to me to change values of something?

Thanks for you help
