Spoilers I have decided to make some built up spoilers rather then use a piece of TE stock
Spoiler servo opening and cover
Top LE sheeting in place on center panel
Tip panel joiner box gets wrapped A tricky job, I hope it holds up
another joiner box wrap, I’ve wound some line off the spool onto a smaller stick to pass it between all the wood structure
Tip panel 57 Grams prior to covering
Tip panel covered
spoiler bay
nose taking shape, I have added a canopy tray as well
another view
Fuselage rear wing bolt down support
Fuselage tail feather bolt down supports
Lightened canopy tray
canopy tray
I’ll add a pin at the front and a couple magnets towards the rear

tip joiners, 4 pieces of 1/16 ply
clamped together for cutting
I sanded some relief to add a CF strip
set together prior to glueing
5/16 x 1 1/4 TE for main panel with notches for ribs
adding the scallop, I start by marking and filing the corner radius
TE added to the panel
and glued and pinned
main panel joiner box fillers and caps
left tip and main panel, TE requires some sanding to match
1/4 ” dowel for securing main panel to fuse

forward bottom fuselage sheeting in place and glued
wing tip alignment pin and aluminum tubes
I’ve added a 1/8 ply reinforcement for the tow hook
before I add the nose block I poured the lead in case the weight is needed later
nose block in place

shear web fillers, I cut then all out of 3/8 balsa , some may like to transition to 1/4 and then 1/8 as you proceed to the tip
step by step rib, shearweb, glue. Usually I mark the spars and set the ribs first.
top 1/8 x 3/8 spar stick in place
Here is a more rigid wing, with the notches cut in a couple ribs for spoilers. I am going to build some built up spoilers

Tow hooks can’t be held tight thru balsa, so I have cut a couple pieces birch ply to go thru the fuse bottom.
added the slots one for the tow hook and the other for the t-nut
a couple filler strips, to make up the 3/16 balsa thickness
a look at the forward fuse balsa underside, the rear 3/32 balsa is already glued in place
getting the fuse aligned to glue former 4 into place, former 3 which will pick up the LE of the wing won’t get placed until I have the wing
Former 4 also has a couple holes to pass the two push rods thru
the tail surfaces, quite simple, one side of the rudder gets tapered, and both sides of the horizontal stab TE get tapered.

Not many visitors to the Shop, but these guys often drop in when I turn the heat up. Grass Fly or Cluster Fly, not to be confused with House Flies. If you look real close you can tell the difference :):)
Nose block, 3 pieces of spruce
Rough Cut
Fuselage cross brace supports, 3/32 x 3/16 strips balsa
Cross places cut to length
Pinned in place
Fuse former gussets F2 and F3
Former F2 at 90 Deg, F3 also gets set at 90
Dec 14
Tail Surfaces, mainly 1/4 x 3/8 an 1/8 x 1/4 balsa. A bit of spruce in the fin, and some pre-cut pieces.
I also got a start on the 4 formers for the fuselage and cut the rear fuselage longerons.
The fuselage sides are 3/32 balsa, with a inner 1/32 plywood doubler applied from the nose to beyond the TE of the wing.
