Hello Ethan, I'm testing the Mkiii as we speak but this can be a time consuming process with some iterations. I'm matching the Aerodynamics/Gearbox/Generator to get an optimum power output for a given windspeed (5m/s) whilst keeping the start up torque as low as possible. Whilst managing all of those variables I need to keep the vibration to a minimum so the turbine doesn't shake its self to pieces as I need to run the rotor at almost 3x the speed of the Mkii enabled by the way in which i've designed the structure.

I'm making progress but slower than I would like, I certainly wouldn't call this part fun! I should know better by the end of the weekend, i'm tweaking the gearbox and hopefully the change in ratio will do the trick...

Thanks Dan
