Pou du Ciel, the Flying Flea



















I've had the tail wheel assembly done previously.

And cut the 2 fuselage sides and 1.75" wide former blanks out of 1/16" quarter-grained balsa sheet.

Fabricated the twin control horns from 3mm aluminium tubing, abt 1.5mm wire and abt 0.8mm wire. Assembly with aluminium from the tubing and BSI superglue.





Then over the weekend, 1/16" sheet and strips (from offcuts naturally) and carbon fibre used to make the vertical tail assembly.





Ready for sanding.
Decided where and how I am placing the radio gear.





 Cyano'd the sides with cross grained formers (all 1.3/4" width)

 Formed the top nose with straight grained 1/16" sheet, wet formed in position to reduce the strain.










Marked and cutout where the motor will go.







 Installed the tested rc gear. The servo rails are balsa strips of 1/4" square (or 3/16", I don't remember).











This picture shows the battery tray, 1/2" gap.













Fabricating the wing pivot cabane strut, first by making the jig, then cutting off lengths of carbon fibre rods, 0.65mm pvc sheet and 3mm aluminium tubing. I figured that aluminium sheath will present greater surface area for later gluing.

 Here a picture of the cabane spot glued with the jig snapped off.






This is the completed cabane assembly.
