Re: Disc Lauching Velocity
Here's a quick video of some testing with a Chronograph taking direct measurements of the Frisbee as it leaves the shooter. The values being called out in the 8-10 range are the voltage applied to the Mini CIM driving the 8in wheel. The numbers being called out in the 18-20 range are the feet per second being measured.

If there is one thing we discovered, the consistency with which the disc is pushed into the launcher is more important to repeatability than just about any other factor.
Here's part two.

We modified the code on the Chronograph and set it up to use retro tape, as is the original design of these sensors. We then suspended it over the flight path .
[EDIT] I just discovered I had not set the distance between the sensors in the Arduino code properly. It was still at 6" while we were videoing, but the sensors were 12" apart. So, the velocities I was calling out were half the actual velocity of the disks. [\EDIT]
