Bag of misc ply parts
balsa sheet cut pieces
Packaging
3d Printed nose block, not sure I will use these
adding up wing panel lengths and fuse width as measured to confirm plan accuracy, plan lines are far to wide for my liking, so I will draw panel outline and all part locations separately in order to build this plane

theres a symetry issue with the stab roots , be careful here
flipped one quite a difference
redrew the stab for the build and cut LE and TE material as well as 1/16 x 1/4 caps

the box for the belcrank builds out to 1/2 inch think
the slot on the fuse top is 1/2 thick
yet the fillets at the fin to fuse is 1/4 inch, as well as the le of the fin

Has anyone ever built this plane, surely to god there’s one out there built from this short Kit, there would have been a huge benefit If it had been prototyped, and the fixes were sent in , I am going to build the fin with 1/2 LE material as well and cut a new fillet, another quirk is the bottom laser cut piece for the rudder was to short, by 1/4 inch the thickness of the post. the fuse top also has the 1/2 inch slot , a good pointer, a true Builders Kit !

It turns out there are missing ribs in both Kits, the root ribs of the tip panel, R8 on the plans , Kit supplier in Texas is aware but un responsive to request for parts

the finished rudder and fin, need a lot of shaping
layout of stab set , I had previusely cut LE, TE, rib caps ,as well as the brass tubes.
the frame is built on shims, so spent some time getting those sorted
the tip, root, spar, LE and TE where the first to get glued together, the root is perpendicular to the spar, bevelled laser cuts need to be watched on the thinker balsa

work starts on the fuselage, I decided to cut the canopy sides out first
and then hold them in place with the corner triangle stock
Nose block shape, found some bandsawn sitka, this would was slated for use to rebuild De Havillands years ago in a Museum

  • 1/16 ss cable push rods in nylon housings
