FTFC20 FB Trixter Beam designed by Hotwax

[hotwax]

My subject is the Trixter Beam. The plane was boxed by Guillow's.

I found the plans at outerzone.co.uk

For the challenge I rescaled the plans of my FB Beam to a 90% version that will fit on 4 sheets of Flitetest Foam. I'm drawing with LibreCAD and have most of the common parts prepared. So I scaled the whole drawing down, deleted the common parts and added them at 100 % size.

The provisional drawings for my entry are ready:

How I'm getting serious, after some time consuming PC trouble, the build has finally started.

First step is building the wings:

Very little parts, just wingpanels, spacers and a diheadral gauge.

Grooves and prebends made.

Spacers prepared with B-Fold.

Spacers glued to the upper portion of the wing. Notice room for diheadral.

Only little glue nessesary.

Prebending the wing and glueing the kinks besides the spacers.

The upper side is now holding its shape.

Closing the wing in two steps. First nose and spacers, then the trailing edge.

Checking clearance with the diheadral gauge.

Opening the center section in order to put a healthy dose of hot glue in.

Finishing with packing tape.

To protect the trailing edge a barbeque skewer is inserted.

Wing is now ready.

Next step the fuselage:

The stiffeners are glued first.

The block securing the powerpod is just inserted and will be glued in later.

Right angels are mandatory.

The bottom is completed.

Keepers for the landing gear.

Some glue added to keep them rigid.

This block will later stiffen the linkage.

Front decking attached.

Will be continued.

And off we go ....

I use the Powerpod out of my FB Beam saving time.

This will fix the firewall.

Now it's time to glue the locking block.

The Powerpod is now fixed.

The cuts prevent buckling of the upper decking.

And glued

The barbeque skewers will take the rubberbands and will stiffen the opening.

Lower decking and and more landing gear keepers.

Fitting the keepers.

Forward and main landing gear will be tied to the sticks by zipties.

The wing is fitted to have a referece for rudder and elevator.

The elevator halves are joined by the barbeque skewer.

Bevels are done

Carved out for the skewer.

Last step is removing the area between the elevator halves.

Tailfeathers glued to the fuselage.

Servos mounted.

Linkage is 0.8 mm pianowire in a small Nylon tube.

The tubes are glued to the block and the fuselage sides.

The bottom is prepared for the landing gear.

Today I finish the building phase

Cutting vinyl for decoration

Cute lines!

Tricycle landing gear

Main gear tied down.

Front gear tied down.

It's a roller.

Let's do the beauty shots.

The build is done.

I start with CG at 50 mm behind the leading edge. This weekend we have high winds but next week .......

I will report.
