HI Mike,
Our elevation is around 960 feet.
The 5065 on 6S is doing well. I know have over a dozen flights logged. I tried a 16x10. It flew the plane well, lots of forward speed.
Verticle was good, but not out of a hover. It hovered well with that prop but pull out was sluggish.
The 17x8 accelerated out of a hover.
I have a 17x10 I am going to try and see what happens. The props I have tested so far are Turnigy wood 17x8, Xoar 17x8, Turnigy 16x10. I have not tried the Xoar 16x10 yet. Ran out of batteries last friday.
The Turnigy 17x8 pulled more amps than the Xoar 17x8 but I couldn't really notice a difference in the air. But at $5 as opposed to $12 for the Xoar, I can't find any fault in the Turnigy wood E-prop.
Here is a small video from last friday. The Reactor bipe is in there for about 20 seconds at 1:29 doing a harrier down the runway. Then I flopped it on another pass because I was coming in with the wind at the tail and broke the prop
The harrier and pull out was the Turnigy 17x8
