Some detail

For me and the techies out there, here a bit more detail regarding how the main rotor pitch will work. Each blade can be turned around it's longitudinal or radial axis individually, via a servo, which is controlled by the laptop we installed a while back as the main control unit. You have to look at the large scale image if you want to see the details. I also implemented a software based rpm control. Once the sensor in the e-motor notices an rpm decrease (for example caused by increased pitch angle leading to increased drag leading to lower rpm at the same torque) it sends a signal to the laptop, which in turn sends a signal to the e-motor to request more torque and bring rpm back to where it should be. At the same time (and this is not shown) battery temperature, state of charge, voltage are also monitored by the laptop.
