The pages on this web site document MY procedure and assembly of my Carden Edge 540I am by no means a professional or "master" builder and these procedures may not be the best methods for you.
Carden provides a nice construction guideline and color photos as an aid to building their kits.
I have chosen to build things in a little bit different order than they lay out in their manual
Part 1 - The Fuselage Part 1
We chose was to build the fuse sides then the motor box assembly, then join the fuse sides to the motor box assembly. This gets the main backbone of the fuse out of the way first.
The fuse is a very basic stick truss construction technique and Carden uses this method in most of their kits.
Lay the plans out on the workbench. Check with a long straight edge that the plans are straight and true. Carden's plans are very good and I haven’t seen a bad one yet.
Cover the side view of the stick truss assembly with waxed paper and start building!!
This is a very large plane and the main longerons of the fuse are so long that the 3/8" square stringers need to be spliced to get the desired length. A simple scarf joint is implemented. Make four (4) longerons. Pin the bottom longeron for the first side to the bench over the plan. I use a long (7 foot) straight edge as an edge to pin the longeron against.
Don’t pin the upper longeron in place. The vertical members of the fuse sides are pre cut to the correct length. Check them all to be sure they are exactly the same length. Glue them in place butting them up against the lower longeron and pinning them to the board over the plans. There are 14 on each fuse side.
As you position the vertical members take note of the positions of the 1/8" ply stab support plate and main wing phenolic tube support plates. These pieces will be glued against the 3/8" vertical members accordingly.
The upper longeron can now be butted up against the open end on the vertical supports and glued in place. You will find that the upper longer fits perfectly in place over the plan.
There are two vertical members fore and two more aft of the wing tube section. This area is where the 3/8" ply anti rotation plates glue to the inside of the fuse. You will notice that there is about 3/16" gap between this 3/8" ply block and the vertical members each side of it. Do not glue these anti rotation blocks in yet.
I opted to move the vertical members against the ply plate instead of leaving the small gap. (Guess I’m just paranoid about that sort of thing!) I figured the ply plate would be better supported with less chance of pulling through the 1/8" balsa fuse side fuse if it was glued up against the 3/8" vertical support.
After the two stick trusses (one for left and one for right side) are framed up you can glue the 1/8" balsa sides to the stick truss. Be sure to put the balsa sides on the correct side of the trusses to make a left and a right side. After this you can glue the ply stab and ply wing phenolic supports to the inside walls against the 3/8" balsa sticks. Notice from pics that I have drilled some lightening holes in ply stab support plates
