History: The de Bruyère C 1 was a prototype French single seat pusher canard Fighter of unusual design produced during World War I. The sole example built crashed on its first flight, and development terminated. Design and development Developed by Marcel de Bruyere, the C 1 was a single-bay biplane with staggered equal-span wings and inverted V-struts. An all-moving one piece canard controlled pitch, while roll control was provided by unusual full chord tip ailerons on the upper wing --Wikipedia

CONSTRUCTION: WING: The wing is constructed using the Dave Rees’ sliced rib construction technique. This technique builds a very light and strong wing. Mike Stuart has a tutorial on this technique on his excellent site. Here’s a link to the tutorial: https://www.ffscale.co.uk/rees.htm The original plane had no dihedral in the top and lower wings, but I would recommend adding 1 inch dihedral under each wing tip. Both wings are built using this method. The

lower wing passes under the fuselage and touches at mid-point on the leading edge. I suggest building a jig from 1/8” foam board 2x4 foot (I get mine from the Dollar Store). I get the dimensions from the plan and build a jig support for the wings to the fuselage alignments. Tom Hallman shows how this is done in his video Building the Beech Twin Staggerwing, episode #7: https://www.youtube.com/watch?v=oHvJr5voVUw&t=961s

HORIZONTAL STAB: The HZ stab is a canard on this model and is made from 3/32” sheet balsa and sanded to an airfoil shape. This is probably the easiest HZ stab I’ve used in my plans. I would try to keep it at +2 degrees in relationship to the wings.

FUSELAGE. The fuselage is built using a jig made from the 1/8” foam board again. Tom Hallman has a great video showing the use of this jig: https://www.youtube.com/watch?v=1yUYY1dqfH8

The formers are made of 1/16” sheet balsa. Because of the unique shape and alignment of the fuselage, you’ll note the angle of the fuselage in relationship to the wings and canard. The alignment has a lot to do with the pusher arrangement. The three “P1, P2 and P3 are of 1/8” balsa and note the sanding of the P3 former to set the prop angle. I’ll leave you to use your favorite prop block and prop construction. The ROT for the prop size is 1/3 the wingspan to start. This is one of the most unusual aircraft of WWI. I just had to try to design a plan for it. I haven’t build this yet and from my experience with canard there are some challenges that must be overcome.
