Did the Novak team driver say anything specific about torque, acceleration or punch differences between the 4.5 and 6.5?

I don't know much (if anything) about velociti brushless setups (or other brushless setups for that matter), but if there is a difference in grunt/punch from standing still...or just plain old acceleration whilst rolling and running...and the 4.5 offers more (in these respects) than the 6.5...then I could understand could this could end up in skidding, wheelies etc and just too much power whilst on the go.

As far as I can gather though, it's all about top end and I don't see why a Tx trim couldn't sort this out? This of course assumes that there is no difference in punch, torque or acceleration between a 4.5 and 6.5.
