Fit the pulley onto the rollers. Ready to run!
Here i am testing a secret board that i can’t reveal much yet.
The rig works well! I have the rig’s remote on one hand, engaging the brakes lightly, and accelerating the board with the remote on my other hand.
Now it’s math time… how do i start 
@DerelictRobot! Is there a right way to go about doing this?
