Amperage Calculator?

[Rivermaxx]

I was told by Nic case when using the calc too use 3.00 v per cell not 3.7 v . I am using 3.2 and 3.30 :1 1/8 scale diffs. I come up with ~100mph. I have done this multiple times so I know my gearing is pretty close. I am just trying to figure out the amperage calc.

It looks like it will be around 200 amps. It will really depend on how fast you get up to speed. The faster you get up to speed, the more power you need. I assumed 8 seconds to get up to speed and you will cover about 700'. You can accelerate slower (9-10 seconds to get to top speed) and you can decrease your amp draw, but you will need a much longer runup distance.
