Proteus Plus PW51

This is a 1.8 m span version of the Proteus wing, with flaps, using the PW51 airfoil and designed to print in a 200 x 200 x200 mm build volume.
Following Peter Wick's advice, the flaps and elevons are bottom hinged.

This version is designed to be an improvement on the 1.65 m span version (which uses the MH45 airfoil) shown in this video:

It has now flown successfully, exhibits excellent efficiency, and handles well (video coming).

It uses two swept 1x10x715 mm carbon fiber half - spars and a rear 5 mm OD x 500 mm long tube spar (the same as the Proteus).

For transport, the design allows the outer halves of the wing to be slid off the spar after disconnecting the elevon clevises. Be sure to use a strong cross-hatch glass reinforced tape 2.5 cm wide for joining the wing sections, e.g.:
