Bengtson Fokker D.VII S400 Model


I thought that it was about time to make Kurt happy and start the thread on my build of Kurt's prototype of the rudder / elevator / aileron version of the aircraft.

A far as I know this is the second prototype of the model with the first one being a rudder / elevator model built by Sam Leonard.

Seeing this is a 'prototype' model, I thought that it would be good to do it in the colours of the D.VII prototype (Attached) - the best thing being it doesn't have any lozenge

I thought that this scheme was a little better than the overdone Raben chicken schemes

Fin


Starting with the easy stuff - the tail feathers.

The fin is nothing out of the ordinary. Most is covered by the laser cut balsa, with only a little bit of strip wood needed

Rudder


The rudder is mostly from the laser cut sheet, again with strip wood supplied by the builder.

Horizontal Tail


The horizontal tail is only slightly more complicated, but still fairly easy to put together.

I used slightly harder balsa for the trailing edge of the horizontal stabilizer as this would act as a bit of a spar. The leading edge of the elevators was from similar stuff

It wasn't until I had glued most of the bits together that I noticed that the elevator leading edges should have been cut for each elevator to allow for the curved trailing egde to come back to the leading edge.

I don't think that it matters doing what I did as a quick swipe with the sandpaper had all the bits looking like they should.

Elevator Joiner


The plans show a dowel joiner between the two elevators, but I don't like this as I can never get it to blend in smoothly.

I used wire instead.

Elevator Joiner


With the leading edge of the elevators recessed to accept the joiner, it all fits nice and neatly

Elevator Horn


I intend to use a pull-pull system for the tail surfaces, so I cut out a horn and reinforced the region around the elevator where the horn will go (roughly in the scale position).

Control Runs


Seeing the up elevator wires on the D.VII run through the tailplane, I needed to reinforce the tail where the wires pass throught with some aluminum tube. As fate would have it, where the holes had to be is not were there was balsa, so some little ears had to be added to support the Al. tube. Here are the ears, the tube has not been added yet.

More photos tomorrow

PS If people are getting bored with such detailed threads, please let me know and I will cut down the level of detail and provide a summary of the build instead.

Rodd,
I rather first glue the wire joiner to the leading edge of the elevators, then cut away the part of the leading edge that separates the two elevators. If idonīt it's more dificult to align them afterwards.

cheers,

Rodd,
I am delighted that you are posting the build. The mod with the elevators is one of the methods that I have used as well. I find that it takes a bit more effort to make the two elevator halves line up with the wire method. However, as the saying goes " to each, his own" . Good luck with the build.

Horizontal Tailplane


Here is a shot of the horizontal stabiliser with the aluminum tubes installed.

Slots for the hinges have been cut and hinges dry fitted.

The tail only needs final sanding before it is ready to cover.
