I have just returned from my 2nd trip to China in the last 2 months. This trip was partially to support my friend Shu Dong Li in a ground-breaking ceremony for a new airpark with a 5-star hotel somewhere nearly to Mongolia.
I then travelled to Shenzhen to visit my motor supplier and my controller supplier. I had a new adjustable-pitch propeller shipped to the motor shop so we could make more testes.
We conducted dozens of tests at different prop pitches, volts, and RPMs.
