Thats an odd motor choice, dont see many people running one of those very often. I would definately say its undergeared though yes, but if its accelerating too quickly then gearing up wont help too much, just gonna raise your top speed more than anything. I would say try it on 4s or 5s lipo geared for about the same speed as it is now or a little higher- that should take the edge off of the aceleration.

I would play with the throttle curve via the castlelink to see if that can help.
