My first foray in to speed running. These are my notes for posterity.
I want to baseline my vehicle first, as I’ve been driving it for this last year, without any modifications for speed:
- Traxxas 2wd Slash
- Velineon VXL-3s ESC
- NiMH Battery 3000 mAh
- 23T 48P pinion
- 90T 48P spur
Baseline Run: 30mph
Replace the pinion and spur to 27/76 and measure the speed.
Result : 33mph
Wow, interesting! That was a huge bump in gearing I would have expected more than a 10% speed increase.
Conclusion: I think we’ve hit the peak discharge rate of the NiMH battery.
Next experiment: I need to obtain foam tires and a LiPo battery(probably 3s), bring the gears back to 23/90, and see how each of those compare to baseline.
