General construction notes:

All materials are balsa except:
	F1		two laminations of 1/8" liteply
	F2		two laminations of 1/8" liteply

	Reinforcement	1/8" liteply to reinforce canard torque rods (approx. 1" x 1" sq. each side)

	Wing Spars	1/4 sq. Hardwood

	Engine Cowl	Thin, Light fibreglass
				or
			1/16" balsa planking

The Canards:
Cut the bearing holes in both sides of the fuselage before assembly.

The canards are completed after the fuselage has been finished, shaped and sanded and covered.

If possible, use a large torque rod designed for operating flaps (i.e. drive horn centrally mounted)

These are constructed from a 1/8" core, cut to receive the torque rod.  This is then lightened as much as possible before gluing it onto a 1/16" piece the size of the canard with no cutouts.

The torque rod should be inserted into the holes in the fuselage just in front of former F2.  Then bent down to an angle of 15 degrees.

Epoxy the torque rod into the slot in the canard, then glue the second 1/16" sheet on top to secure it all in place.

The fuselage:
On the plan, the formers are shown with the wing (shown as a gap) separating the top from the bottom.  The easiest way to build the fuselage is to build the bottom part directly onto the wing.  The top part can be built as normal, (don't forget the reinforcement and holes for the canards) then added to the wing.

You will need to make access hatches for the tank bay/canard control horn and the rest of the radio gear at the back.  The easiest way is to cut the hatch in the bottom of the tank bay, and to make the bottom section aft of F7 removable.  I have not shown these on the plan as you may prefer a different method.

Radio Installation:
To get the best from the plane, a computer transmitter is required to mix the canards with the elevator channel - remember - up elevator should move the trailing edge of the canard down.  The ailerons and elevator are mixed to provide elevons.  Make sure there is sufficient movement to get aileron control when full elevator is applied and similarly, elevator control when full aileron is applied.
Note:	The canards are NOT sufficient for pitch control on their own

Wing:
If required, lightening holes can be made in the wing.  Where full length hardwood spars are not available, ensure that the scarfe joints are staggered

Engine:
A powerful .40cu. in (6.5 cc) engine with a hign pitch and narrow diameter prop should suffice.
