You can’t see the prop when it is spinning...

I must admit.. my 2 blade wood prop was, while being beautiful, not a success. So much for nostalgia…

I got really good take off performance but I lost in speed and got vibrations I didn’t need… 

Another problem I had not anticipated is the need for different pitch during really hot summer periods compared to the rest of the year…

So I increased the pitch on my old smooth running Warp Drive and put it back on. I gained 15 kph / 10mph (10-15%). We will see about the consumption...
