Got some more building done. Second boom is completed and the wing center-section. I was quite pleased that the fit of the booms to the wing was very close - requiring little extra trimming. I will have to open up the area where the wing passes thru to compensate for the tissue thickness, but that's no problem.

So far, the fuselage weighs 2.71 grams, the booms @ 1 gram each, stab @ 0.37 and the wing center-section @ 1.65 grams. Fins/rudders and wing outer panels will be addressed today (i hope :mrgreen: ).

Tip panels are practically done - just need to add the main LE and shape the TE. The center panel needs just the boom support ribs and a sub-spar. Really pleased that the tip panelsare exactly the same weight at the same construction stage @ 0.85 grams.

Added bonus... everything seems to fit :D !

Just had to clamp everything together to get an idea of the whole mass of this puppy. For a 19 inch span model, it isn't "small" :o

I am a bit concerned about the survivability of the booms as designed...

Rudders and sub-rudders done. I've tack-glued the rudders to the booms. I've decided NOT to bother with the landing gear - I want to first determine the this thing flies and is somewhat survivable. Total weight of all components: 9gm.

Got the nose block roughed out and started covering. The booms are a PITA to cover and are very prone to SHS (starved horse syndrome) - have to figure out a lightweight cure...
