Optimum Brushless for high speed...

[motormania]

I have an interesting request...

I'm going to be racing a full size car in a PR stunt very soon and want to make sure I have the most powerful brushless for my 1:10 scale Xray Touring Car. I normally run a 13.5 stock brushless with my Novak GTB speedo.

What would be the best lipo/brushless combo to give me the fastest car possible...

I have to be careful that I can still control the car, this is for PR purposes and it's being filmed so I'm sure that there will be some 'artistic licence' used, but still want a quick car. I'm guessing, as the whole Brushless thing is still very new to me, that like Brushed motors, the smaller the number the faster the motor.

In other words, I currently run a 13.5 stock brushless, but if I use a 5.5 that'll be much much faster right?

I can probably get away with just a high capacity 7.2v lipo. I'll get a couple so one can be on charge while we film using the other.

I have a Novak GTB speedo that came with my Novak 13.5, will that handle a faster motor, or will I need to upgrade the speedo to run the super fast brushless?

Thanks for the feedback, looks like a couple of higher capacity Lipos and a faster brushless is the order of the day
