The old one is old but, that was the point of the new one lol. Apart from the problem I'm having with the new one, it runs alot nicer with it and has less knock. The old one I've noticed now is alot more slower to respond to changes (e.g. it still says I'm doing 3km/h till I've been stationary for about 3 seconds lol)
I need to find another 33 to see if it does it on that. If so then I know its a unit problem..... or 33's have a really sensitive problem with new power FC's
