Make the wing cabanes as per plan from 2x8 spruce and part C1, position the cabanes into the fuselage, slide in the wing
mounting wire to assist in alignment and glue the cabanes to the fuselage. IMPORTANT: make sure that the wing mounting
wire is horizontal, square AND in the right position above the fuselage BEFORE glueing the cabanes !
Rudder:
Make the rudder from the 1,5mm balsa core as per plan and place 2x6 balsa stringer and ribs on one side first, do the other
side with ribs also, place T7 and T1, place 2mm inner cable with the top flush with the upper side of the lower T8 and 4 mm
protruding through the bottom of the rudder, this is to give sufficient clearance to hook the rudder into F17 Sheet at position
of T8 with 1,5mm balsa and cut a slot for the pivot tube.
Laminate the tip and bottom with strips of 1,5mm scrap balsa for strength.
Make a 90 degree bent at the end of a piece of 0,8mm wire. Drill a 0,8mm hole into the middle of the 3,2x20mm plastic tube.
Guide the wire through the inner cable and push it through the plastic tube .
Glue the 0,8mm wire into the 3,2mm plastic tube, but make sure that wire and tube remain free to rotate in the inner cable.
Also leave enough room for the bearing bush in F17. Cover the rudder and place control horn H2.
Assembly:
If all parts are covered, it’s time to assemble the model:
Place wing servo and screw into F10, Place F11, and place rudder servo and make small steering cable opening into fuselage
and place steering cable Place rearward wing.
Make the frontwing mounting wire from 2mm mild steel, slide 3,2mm plastic tubes over the wire and bend as per plan (minor
adjustments might be necessary), fix the wing mounting wire onto the wing with parts C2 and glue tubes onto C2. Place H1.
Place wing mounting wire into cabane (push the cabanes a little uot to pop the wire in).
Connect steering wire from servo to wing, the wing neutral is set at a negative incedence angle to the fuselage, the trailing
edge is higher about 2 mm higher than the leading edge, as measured above F19.
Make the rudder braces from 1,5mm mild steel wire and 2mm scrap balsa as per plan, it is important to make the scrap balsa
as tight as possible to the wing so there is a minimum of play between the rudder braces and the rear wing. The length of the
two braces should match exactly.
Hook the rudder into F17. Hook the rudder braces into W8 and screw them to the plastic pivot tube with 2,2x6 sheet metal
screws as per plan, make sure the rudder moves free and is straight and true to the wing. Bend the rudder pushrod as per plan
and install. Trim the rudder neutral slightly to the right as per plan.
Place windscreen with small pieces of double-sided foam tape; do not use CA here as it will fog the clear plastic.
Motor:
Cut off all unnecessary parts from the gearbox and place the motor /gearbox into the Pou with help of rubber bands, the
motor might move a little when powering up to full speed. A word of advice: do not use tie-wraps, as the motor will work
itself loose from its bearers after a while due to the increased temperature.
Fit the landing gear with light wheels as per plan.
Balance the Pou du Ciel as per plan, the Pou is forgiving on the CG but when nose heavy a higher starting speed is required.
Like any other plane, tail heaviness is a no-no.
Flying:
Flying the Pou is easy but it is sensitive on the rudder. Take care not to make the movements too large.
Flying thermals is possible,but the Pou doesn’t like strong winds.
