Need help/advice on my setup

[pumpkinfish]

I had to grind the can down just to fit the 11t. The Kyosho rear chassis brace is one of those blue hollow tubes and it is hard to do any grinding with that. Do you think the 10t will give up too much on the long front straight?

I did have the pack come off the charger a few minutes before race time.

Do you guys think I should go to a 2000/kv motor or is my 2600/kv fine at this point? I also don't know what I will end up gearing the MBX6, so I have to keep that factored in what ever I end up doing here also.
