The trailing-edge support tabs on each rib are scored for easy removal after ribs and spars have been secured, but because they're so thin, they snapped off while I was installing them frustrating, to say the least. Pay close attention to lining up rib 3, which is angled to allow a close fit to the fuselage. I needed to put in spacers to close this gap after positioning the wing. A neat touch is the incorporation of the wing servo tray into the construction sequence. The servo tray is finished with die-cut sheeting, making a nicely finished servo mount.
Shear webs are precut.
Sheeting and joining panels is straightforward. The ailerons are precut, so hinging is all that is required before final assembly. A builder would need to be very careless to not produce a straight fuselage. The sides, top and bottom are cut to accept die-cut formers, and all parts fit very well. I used large office and cabinet clamps and rubber bands instead of the masking tape suggested in the instruction booklet for alignment before gluing.
