This morning I tested the 14x4.7 APC's on the S800 and got 17mins duration with a fully loaded model with Zen fitted including the standard heavier zoom lens. It was set to GPS mode and I left the TX on the ground for most of the flight. Then I saw a red flicker so I landed. So with the help of some guys at the club, we then decided to try and shoot some video to show the vibration on the arms and got another 2 mins. before seeing the red light again. The battery (11amp. Maxi.) level when I started to recharge it was 22.2 volts so I could have gone longer but I like to look after those little gems. They are expensive.
This shows me that those APC's are quieter, more efficient and run longer. They also offer proof that the carbon blades are the primary cause of this flexing in the arms and high vibration levels.
They are about 14 usd for the APC pair and the DJI Carbon are about 75 usd. aprox. The wind was quite gusty and my feeling was that it was typically a lot more stable than on the DJI props. I don't think you guys who bough my adapters will be too unhappy with your investment......
Most of the movement that you see is me on the sticks.
We still have 4 more props. to try....
