H.M.I. - Hydro-Monoplane 1 (WNW Hansa-Brandenburg W.29)

Recommended Posts

Posted (edited)

Time to crack open the 2020 season with a new build...
I've decided to continue with part two of 'The Duellists' the Hansa-Brandenburg W.29.

It's the only Wingnut Wings kit of a plane used extensively by the Royal Danish Air force.

In July 1919 The Royal Danish Navy bought 1 Hansa-Brandenburg W.29 from Hansa- & Brandenburgische Flugzeugwerke GmbH.

The first year the Danish Navy had the aircraft, it was tested thoroughly and it was found that it in every way exceeded the planes 
that had been operated before. When the aircraft was inspected at the Navy aeroplane workshops, it was measured and plans were drawn.
In the following years no fewer than 15 aircraft of the type were built under license, at the shipyard's aeroplane workshops.

 

H.M.I No. 20-30 (No's 21, 22, 23, 24 & 26 were used twice)

 

They served from 1920 until the last two (20 and 29) were written off due to age in the spring of 1931.

In the autumn of 1921, installations were built on board the two armored ships
'Olfert Fischer' and 'Peder Skram' so that in the future they could carry the H.M.I.

 

In 1927 the armament was dismantled for weight reasons.

H.M.I.'s lined up at the naval base in Copenhagen 'Margretheholm'.

 

Initially, the planes were painted "navy" (medium gray) with white numbers. 
Later they were all silver doped with black numbers.

I have actually been looking forward to begin this for a very long time and I think it will be i nice change, from the 'hairy' Aeromarine

build, to an hopefully almost OOB experience...

Engine, engine, engines...

 

I have been spending some time building and detailing the engine for the H.M.I.

The kit engine is nice, but I wanted to add some extra detailing, getting some practice with the small fiddly stuff.

The spark plugs are mode from 0.6 mm nickel tubing and 0.4 mm brass wire.

The valve lifters are reworked, adding wire springs on top of the cylinders. Spark plug cables  are made from 0.1 mm lead wire.

Throttle added with spring and mechanism + some additional tubing.

On the other side the push rods are made from 0.4 mm tubing. Some small handles are added to each of the cylinders. Some 'pipe'

ends were also added.

And all of it times three... Why?

I found this photo in my archive, showing some sort of transport cart with an engine.

I just have to add this to the build somehow...

 

The last engine, well lets just say, that I have plans for another build/scratch involving a Benz Bz. III 150 HP.

Easier to do more engines when your at it....

Work continues with the conversion of the exhaust...

This photo shows the curved exhaust stacks being passed down to underside of the fuselage.

I bend some brass rod and made a silicone mold.  The exhaust stacks are cast in resin.

Using the kit template to get the correct distance between the stacks.

Some of the converted parts, incl. the cowling panels with the armament removed.
