Concord special parts

The parts shown are from my Aero parts system and include 3º tapered couplings to set dihedral/anhedral angles, 5/16" & 3/8" box joints and ¼" square, threaded spacers for fuselage constructions where narrow strip and angle combinations are chosen.

Others involve bending 90A parts to three different widths for cross bracing and to make formers for cockpit construction and as supports for panel work.

The trunnions are left and right handed, so they can be used as engine bearers and for other purposes on larger scale model aircraft.
