Woo hoo, we have Plans, and ribs not much else though
From Plans Nov 05, very much a Scratch Build Plane gonna be at this for a bit I reckon, should be fun though.
Tubing needed for wings, tail all the lengths can be measured off the plans
- 3mm – leading edges
Fuselage ( some additional Info)
50 deep x 40 wide by the le and 70 deep and 40 wide halfway......made to fit the servos batt etc.
1.1 meter from the rear bolt to the hing line on the rudder
Yoke home made but from CF perfect.
Main spar tubes made for >> me,,,,,UD (uni Directional WH) >> carbon very strong, >>> but >>> there are many available in Europe. > No diagonal ribs, >> Just 3 x 5 mm >> hard > balsa strips > Fuselage, just 5 and 10 mm plus some >> block >> >> balsa >> sanded > to shape and skinned > in carbon and painted. >
Wing MAke sure that main spar tubes are VERY strong and will not twist!!!! Yes, D box sheeted. A carbon skin. But hard balsa is fine Yes about .5 carbon, or .5 ply
Consider tubes 1.5 MM wall for main panel, 1 MM for the tip panels

Ultracote is on it’s way….for an idea of what I’m thinking (currently) just picture trans blue on the center panel, with a white fuse and black boom. I may use that lite trans white
as well perhaps mid span, but I also have some fluorescent trans yellow on the way just to see what it looks like…..
Boom 35 to 25 mm 1.2 meter long 1.2 to 1.5 mm thick

Mr C cannot provide tapered tube, have found another source, and inquired
will still offer list for rest of CF to him to get a Quote Shipped
All trailing edges 1 mm thick CF will get the width from the plans. and notch ribs to suit.
Consider applying a thin cap strip over top to strengthen joint
I’m beginning to see this come together with CF tubes in the fuse boom back to the tail
6100 and 6125e(stab) for the fuse
6125 minis for the wing
4 cell Eneloop for the battery.
I have glued up a few pieces of balsa to a CF tube.
At rear I used something called Lepages 100% glue, in a red bottle, it stays soft well after three days. Seems plieable, and If pushed hard enough nearest the tube the balsa wood move and the glue appears to want to shear
Nearer I use JB weld, it’s black, and not so nice If you don’t get a clean fillet. I like to use JB weld for CF push rod end to threaded link glue joints.
The two nearest glue joints are with Laminating resin
The nearest I use a baby powder filler to give it some viscosity to hold a fillet shape, and the 2nd one in from the front has shredded FG strands added.
With the shredded FG strands a little more care needs to be taken to create a uniform fillet as some strands get hooked on my fillet tool.
Perhaps Carbon fiber LE D box sheeting
. 5 mm thick
Bonding CF to Balsa
