Another Arrow, ready to take to the skies! (Well, after I add the camera up front and balance her out).

rockyboy: Looks good! I like the carbon fiber vinyl
I see you went with the standard Z bends in the pushrods rather than a linkage stopper like you suggested to me. Are you planning on just using sub-trim to work out the reflex and not worrying about the lost throw?
Also while viewing your 3D printed center pod I had an idea. What if the pod was printed with a spar coming off of both sides to go into the wings? This is the weakest link in the airframe and where all 3 of mine have ultimately met there end from the wings tearing off the center pod on the top section. Seems to me that if a spar was added to the printed center pod right where the box spar is or slightly aft of that on the top of the wing you could add small slits in the wing, then put glue in the slits and pop the spar in them as you glue the center pod in. Finish it off with a top coat of glue and wipe the excess for a much strengthened design. I have no experience with or access to a 3D printer or I would try it myself. But just an idea for someone that does.......
"There is a second option, which is used quiet often with Wings: angle the motor (or motor mount) a tiny bit."
Micropitt: It's funny that you suggested putting a tad of thrust angle on the motor. I've read and seen this on the forums and was contemplating doing just that. Then yesterday I watched a video on Youtube of a restored 1943 Northrop flying wing
https://youtu.be/2eZjIx_ViOA and those motors DEF have thrust angle! Which made me consider it again. Then about an hour later I read your comment and my mind was made up!
Any suggestions on the amount of thrust angle? I was thinking between 2-3 degrees? I will be accomplishing this by adding the angle to the power pod itself where the firewall is attached.
I'll be building v3.0 soon and will be sure to post pictures and any knowledge gained along the process
While I'm on the subject does anyone know what I did that caused my first batch of pictures to post upside down? I'm sure it's something simple I missed being a noob. I was thinking I could invert the files before I posted them to remedy it. (I imported the files directly from my laptop to the post....
