So I got a little bored yesterday and was doing some research on people finding speed of their spartans and the speed sensoring not working since spartan doesnt use gears? Anyways Ive always test the speed of my RC's with my cars GPS so i figured why not try it in the boat. Zip locked the GPS and put it to the front in front of motor and zip tied it to the area where the Cover slides in...
With nimh battteries in the full front position I hit 24.5 on GPS with the included batteries. I then moved them to full back position in the boat and hit 29.9
I then ran 11.1v 25c 5000mah lipos in the full forward position in battery tray and I hit 49.4..
for using a car's gps I'd say these readings are pretty accurate and traxxas is spot on with the speeds out of the box! I will be making some videos later this week/weekend that show this figured id just post the pics for now.
