The current load drops off at top speed. I have had cars average peaks 70-90amps on acceleration but once up to speed it drops to about 20 amps or so.

I have even seen the amps drop lower than that I think with my buggy...

This will vary depending on specific motor and gearing, etc... but the load does drop off a lot. My example was for a low-geared truggy... only topped out in the 30's. Gearing for speed runs will put a lot more load on the car at speed (gear ratio/wind resistance...)

At any rate, it makes guessing the voltage drop kinda tricky. Guess I need to strap the micrologger in for a few speed runs sometime...
