Hmm...sounds like your rig is set up pretty good. Don't tinker with it for now. In regards to the Revo vs. Buggy thing, a buggy
should accelerate faster, but you need to take into account the motor the buggy has, is he getting more wheelspin, etc.
Best of luck on the next races.

We have one tentatively scheduled for 20SEP, but we'll see how that works out.
As for the TP 40c packs, you can find 'em on amainhobbies, rclipos and I think stormer. In regards to the 43c Enerland pack, they have been released...I haven't seen it anywhere aside from rclipos.
I looked at the specs, but I'm not too impressed.

It's a 43c constant with a 70c burst. To add to that, they haven't released a 5000mAh capacity battery higher than a 2S. I'm waiting for that one. None of my packs are below 5000mAh...and I don't want to start now.
I suppose I'll stick with the TP 40/80c packs. So far, they have been cranking out the most juice.

I love it.
