I hadn't actually been aware of this at all, though it's not a problem with the receiver - with the actual ESC. I think it's more to do with the fact that I had a difference of charge between them and maybe the problem had just been getting worse and worse until today it went. I think dual controllers will probably be where I go from now on. MY power source is a 12V Li-Ion battery from an Argos drill... I was only using the one, powering one ESC since I thought that was mroe or less sufficient and didn't think there was an issue with balances. Harsh lessons again, I guess.

Thanks to everyone for their input though. True stories for sure about roboteers pulling together, it feels good.
