Interesting Frank , the cowl gives away the type and nice to see you tackle another resin kit

Thank you very much to all, and welcome to the show!

Well spotted, Alexis! It is a Aviatik 30.40

Exactly. It is a resin kit by Alliance Models in 1/48.

And now a question:
This type is very comparable to the 30.27 biplane, it has two Schwarzlose MGs on top of the cowling, in front of the cockpit:

In the side view of the Aviatik 30.40 there are no visible MGs, but a hole on the very outer radius of the cowling.
Is it possible that there was internal MGs?

On the other hand the 4-blade 30.27 has the holes _and_ MGs on top of the cowling:

So I assume no weapons. What do you think?

Cheers,
Frank

The upper hole in the cowling doesn't look oriented correctly for a machine gun to fire through, IMHO.

Thank you for your opinion Ken, I think that now too.
The gun barrel needs to be outside of the rotary arc, so that would not work.

After checking the pictures in best quality available I think this one has no mounted Schwarzlose guns, but is prepared for them. So I modified the fuselage accordingly. More once the cockpit is finished (which will need a while).

Cheers,
Frank

Fascinating aircraft you find, Frank! Great skill, as ever, producing that cowl. How did you create that polished pattern? Polishing or paint?

Cheers
Fredrik

As I wrote, the kit resin cowling is really great, but would require painting (the 5 versus 7 slots issue is not that important).

So I made one from aluminum, polished it and applied the pattern with a rubber polishing stick in my Proxxon drill machine. May be I will add some more between the exiting ones.
This is a picture of the polishing rubber stick from the Quadruplane build. I found a set of different rubber, felt and other polishing sticks with a 2.4mm shaft years ago in a super market. Now they are useful

Cheers,
Frank

I suspected that. Looks great Frank!

I've been thinking about ways to that on a plastic cowling. But I suspect your method won't work on paint. A rubber bit would probably just remove the paint and probably melt the plastic as well.

Keep up the good work!

Sorry I have No answer for your question. If I took a WAG I would say Unarmed!

Hey Frank ,

looking at the photo of 30.40 I believe this was unarmed . The two small holes in the cowl aren't gun ports , too small for that . Perhaps for servicing the engine or filler ports for oil/fuel ?

You are right my friends! After more deeper analysis of the pictures in better quality I say unarmed too.

Resin

In meantime I worked on a lot of parts, but no subassembly is ready yet. But some pictures as a sign of life.

The quality is not bad, but very thick sprue gates.

Another example are the wing struts.

After removing the sprue on the tail of the fuselage a cut out for the tail plane needs to be done.

On the wing I cut the ailerons. They are very thin for my usual brass wires but there were four visible hinges on each side, so I added nickel silver stripes.

A detail view. On the aileron there is a bubble.

I closed two bubbles with stretched sprue.

I cut and added the same hinges also on tailplane and rudder.

There is a picture from the back which shows the special shape of the ailerons, but the kit wing was flat.

So I bent the ailerons with some heat. I hope they will stay in this shape for a long time!

So the first parts are primed now.

At least one subassembly in done - the instrument panel. There is guesswork, so I looked at other Aviatik types to get an idea. Eduard PE and some brass on real wood.

The next task is to complete the cockpit to be able to close the fuselage.

Cheers,
Frank

Great work as always, Frank -

Love your instrument panel

Your instrument panel is a thing of beauty Frank and I love those bent ailerons and all the hinges. Bending those resin parts has worked out really well, must have been a bit scary!

Spectacular work, Frank. I allways admire your skills, when it comes to those delicate parts.
Bye,

Thank you very much Rick, Dave, Richie and Manni!
Progress is at the moment slower then expected, but I will continue.

Yep, and I had two problems:
It bent back after a while, so I need to go a bit further and/or hotter

And I wanted to keep the hinges side straight, so again my little Proxxon machine vice was a big help here (used also on the mill and as squeeze tool for struts).

Cheers,
Frank
