Update

I made my first flight today and it went very well. I outfitted the plane w/ a CRRC 26cc engine, and HXT 12k servos (~210 ounce torque @ 6 volts). I am currently running a 16x6 prop which will be changed to either a 16x8 or 17x6 once the engine breaks in as it needs more vertical. The video attached shows a couple of clips from my third flight of the day. First a take off and climb out, then on to a low fly-by climb and into a semi flat spin. I say semi because I set the plane up a little nose heavy for the initial setup and I don't have full throw on my elevator so I couldn't get it to flatten out. This plane lands great and is very stable, i actually got it to hover at half throttle fairly well for me. The CG setup was done at the wingtip and came out at the line where the sheeting on the wing transitions into the unsheeted area.

killer!
let us know on the final prop choice. probably do good with an apc 16*8, 16.5*5w, 17*6 or a 17*6n maybe even a 17*8n.

email XOAR and ask them what propeller they would recommend. they have tons of props they dont list on their website.

Do you fly at red stick?

16X6 is a bit small for your engine. I fly this plane on a 17X6 prop which gives good performance and lets me slow down easily for landing. 17X8 gives more speed, but I like the 6" pitch better for this plane.

You are probably going over 9K with your prop and your engine is probably happiest turning in the 8K to 9K range. Also, with gas engines, a "break in" prop is not required, fly it with your flight prop while it gets run in.

It's a nice plane, I'm sure you will enjoy it.
