Nice Rebuild!
A friend of mine preaches that a re-build is always faster than a build-build, no matter how bad it looks.
I had seen the video of your crash before. Heart-breaker! Looks to me like it got off and tried to climb too soon, although I can't speak to CG and wing incidence just by watching the video.
Another friend of mine had an equally heart-breaking maiden, for other reasons:

I have to share a little responsibilty for that one because I actually held the plane while he checked control surfaces pre-flight, but I didn't force him to let me hold the transmitter and check them myself. I think his finished weight was 47 #. He had G-38's and it seemed like plenty of power.
Nick Ziroli told my friend that correct washout and root incidence is very important on this model. Too much washout is better than not enough, but "just right" is best!
Good Luck! Keep us posted!
