I was wondering if anyone knows of a cheap effective way to determine what the new top speed of my torment is. It started out as a 2WD brushed and stock Horizon is saying it would run 25 MPH off the stock electronics. I have upgraded to a Kinexsis 4000 KV brushless motor and ESC system along with the metal gears and I usually run it with a 4100 mAh LIPO battery. I also snugged down the slipper and the thing seems to fly now. I want to know what my new top speed is, any suggestions on how to measure that.
