Peter,
Bad luck for sure. If you need a replacement spar let me know as I have "several".
One thing I learned early on in my builds was the outboard spars are very difficult to slide into the outer wing sections. I recommend using a moto-tool with a grinder attachment to thin them down then apply a little Vaseline along the edges. This will go a long way to easing their fit. Might be a little late with this advise, sorry!
John
