Kyosho Inferno Race spec q?

[Tastiehastie]

Bought one of these today, and it comes with the new digitial controller.

My question is that it takes off quickly, but feels strangled at bit flat out, like it has more to give.....is this a gearing issue, or a I missing something on the controller to "Turn it up a bit"

It's almost like 80% of throttle, and it just needs unleashed.

Cheers.
