Li-Po or NiMH? I'm confused.

BTW, Mike, I have an excel file that has different vehicles, different KV motors, battery voltage, RPM, tire diameter, pinion, spur blah blah blah just like you! Hahaha That's pretty interesting. I started doing it back when I was 14 or so years of age on Appleworks spreadsheet. Back then, it was done so I could measure speed, motor RPM, tire RPM, and stuff based on a speed trap and I had different ratios etc. I used it and came to the realization that sometimes a super large pinion will actually be slower than optimal gearing. After a couple hundred entries, the old Apple IIe would take a good 3-4 minutes just to recalculate and that's how I got an IBM AT. Fast forward like 17 years... and now we have Excel worksheets. LOL

I've found voltage drop pretty minimal actually in speed runs. Most of the voltage drop occurs during hard acceleration, but as it nears top speed, voltage drop is usually within 10% of "voltage". Have you noticed that too?
