Best controller for 12-16 cells?

40-45 mph is the topspeed you might get on 16 cells

you can keep the same gearing and tune your radio down to 60-70 percent. This gives a longer runtime as well.

About the warranter, you act like you are going to ruin it, just run it, use it with sense, gear it with sense and the warranter from BK is good. Much better than from schulze.

The 3-4 day is very quick, i love the service from Castlecreations as well. It is by far the best i know of. They don't have got the mamba maxx out yet, unfortunately.

The XL will eat his way through your diffs and make pritzels from your driveshafts.. on 14 cells, it will hold up a bit. but it will wear out much faster. Unless you are easy on the throttle.

I run a 7XL/BK18120 combo, geared at 16/51 and on 16 IB3800 cells. I just radared it at 44mph, and it gets there pretty quickly.

Runtime is prett decent, I can get about 15 good minutes of hard running. I haven' raced yet with the IB3800's yet, our track is being overhauled for some airtime.

CVDs, Steel Idlers, and diffs upgrades are going to become a necessity when you start running it hard.
