This one also interests me, according to some guys the 40-MHz is faster than the 2.4 with the Futaba for instance the HRs receiver is advertised as the fasters receiver you can buy and this is a 40-MHz receiver,

For simplicity and no messing around 2.4 is the best option but is it for speed?

Only thing i do is, Steering curve, usually set to about -25% and then i take it apart and make sure the balance from throttle to brake is the same and the position is central. Cant stand a different feel.

Obviously i adjust the steering balance etc but everything else stays the same as default.

I have too many other things to worry about. The transmitter is the last one :)

I went from a futaba HRS 40 mhz set-up and then brought a futaba 2.4 ghz receiver and mudle for my 3vcs. Can't say I noticed any difference (apart from the lack of interference :D) I think it's one of those things that the Pro-boys will notice the improvment in performance whereas us mere mortals wouldn't.

I wonder if hirosaka would notice the difference when driving with his feet?
