With the back bottom part covered the front is on now.
The two side removable covers must be made as well as the doors for the landing gear.
I know the covers, just fill the up with balsa, shape them and covering finish...done...
However, I will make a mould of both covers, the lh, rh and gear doors, in this way epoxy parts can be made.
See the pictures as usual,

Noël

...and yes, working on two models now...
The bottom of the fuselage needs to be finished first to be able to make proper moulds for the bottom side pieces and the doors.
All had to be reworked a bit but looks now what I want it to be.
The bottom is now completely sheeted and needs now a finishing touch to sand it down the last time, I hope.

But before I could filler the bottom sides and the rear, I had to put sheeting on the fuselage sides.
More to come...

...the bottom part covered with 0.6 mm ply...
I had to take the plastic strips off again due to not high enough.
I needed to add another layer of ply to get level with the rest of the bottom.

The thing is, after the mould will be made most of the front bottom covering has to go to allow the epoxy parts, scaled, to go in.
This will be for later to show what and how...

...a bit more has been done on the bottom part.
Waiting for some dry warmer weather now to make the epoxy mould...The good weather is coming next week, they say...fingers crossed!
But due to the cold, etc outdoors I did some work on the tail wheel.
And finished now to fit the tail of the fuselage nicely.

Nonono, Gert, no way!!!
More work has been done lately.
The mould was Ok and the first set of the front bottom, being the doors and side covers, is ready.
Now with still the wooden parts on I think is was wise to make the cowl first.
In the very beginning of this Milan project, I checked on the company in Germany, Putzer, if there were changes between the RF4 fuselage and the Milan. The answer was, that almost all was kept as the RF4. Later I did Google the net, I did find help with the owner of the real Milan in the UK.
Studying the pictures, told me that there were a lot of changes towards the RF4 fuselage.
This was when I asked for a few measurement to compare the RF4 drawing with I could see on the pictures.
This involved a almost complete new design around the wing joiner aria and the rear of the canopy and the first two formers of the turtle back.
The cowl was also modified due to another engine installed, I think.
Being smart at the time Mick Reeves came out with his 1/3 scaled RF4, I ordered the canopy and cowl. Later with all the necessary measurement in hand, I learn that neither of them could be used for my Milan.
That is why I make now my own scaled cowling and later the canopy too.
First the front top cover was made to be able to be able to grind all to this reference.
See the pictures, notice the small brass tube I used dia 2 mm inside 1 mm with a 1 mm spring steel rod to hold it in place.
Worked well because we decided to make the front cover removable to get better access to the fuel tank and battery location.
I designed also a new fuel filler cap to go into cover. Four small pins lock the panel in place...
