Hand Helicopter Launcher

Designed to launch a child's toy "hand helicopter" higher than a human can.

The challenge is surprisingly hard, and so far, even this version can't quite achieve it.

First working version had a maximum RPM of around 6,500. Still, the helicopter only launched to ~80% of the height a proficient human can get to. 

The second working version got an upgraded motor, so can spin to around 13,000 RPM (unloaded). This required moving away from the prefab stamped helicopters and moving towards a custom design and new helicopter driver. Changes to the arduino code meant a faster launch with less established turbulent airflow.
