First, thanks to Jason and Stuart for the pictures and discussion. You have both saved me a lot of head scratching.

Today I finally got the opportunity to unwrap everything and do a weigh-in. Fuse is 735g, wings are 404g each (both are the same), starboard stab is 122g, port stab is 118g, canopy 145g, rudder 64g, gear (both) 127g, wheelpants (both) 31g, CF Firewall + former + servo tray 71g, battery tray 34g, cowl 78g, wing tube 118g, stab tube 15g, bag of hardware 85g, balsa sticks + copper clad wire (what is this for) 12g. Total weight before servos, receiver, radio/servo battery, servo extensions, motor, ESC, motor battery, prop and spinner is 2,564 grams or 5.65 lbs. Anyone think I can make 5kg starting that heavy?

Stuart, what did your wings come in at?

Servo mounts are installed. Wing servo openings are 36.5mm x 21.0mm. Elevator servos mount in the stabs with openings of 27mm x 16.7mm.

Anyone have a guess at the function of the copper-clad steel rod?
