    Hi all,
    Something I don't do is to build two models at the same time.
    However I'm starting a double build.

    The first is the 'HPH Models' 1:32nd scale resin model of the Italian Macchi M.5 floatplane.
    This is a commission build for the Commander of the Italian Frigate 'Federico Martinengo'.
    His ship was named after the Italian naval pilot of WW1, Federico Carlo Martinengo.
    I've previously built a version of this model and have a build log on my web site.
    The only differences between the two models will be the aircraft markings.
    As such, I won't create a build log for this model here on the forum.

    The second build is the 'Lukgraph' 1:32nd scale resin Hanriot HD.1.
    This was on order before 'Copper State Models' announced their intention to release this model.
    The model will be of the Belgian Hanriot HD.1, serial HD 24 of Willy Coppens, Escadrille 9me during 1918,

    Excellent choice of subjects, Mike @sandbagger
    Looking forward to both of them.

    Hi all,
    The cockpit has been completed and the fuselage closed up.
    As usual, working on 3D printed complete assemblies, such cockpit frames and engines, can limit what can be achieved with painting and assembly.
    However, this kit didn't present too many problems.
    That said I did replace the kit supplied cockpit instrument decals and pilots seat straps.
    I used appropriate instrument decals from the 'Airscale' WW1 generic instrument set.
    Also the kit supplied photo-etch seat belts, which are basic to say the least, are too short.
    They can't be attached to where they should be on the cockpit side frames and still reach over the pilots seat.
    So they were replaced with 'HGW models' fabric belts made up from my 'spares'.
    I've added the following:
    Throtle control rods (0.4mm Nickel Silver tube).
    Fuel level indicator (0.5 mm Brass tube and copper wire).
    Pulsometer pipe ('MFH' 0.4mm flexible tube).
    Tachometer drive cable ('MFH' 0.4mm flexible tube).
    Unidentified pipe on cockpit left (copper wire).
    Machine gun trigger cable (lead wire).
    Rudder, aileron and elevator control cables (0.12 mm mono-filament and 0.4 mm Brass tube).
    Cockpit side, bottom and seat frame crossed bracing wires (0.12 mm mono-filament and 0.4 mm Brass tube).

    The cockpit opening of this aircraft is smaller than most, so even less is visible once the fuselage is closed up.

    Also the engine is complete.
    The only additions made were adding valve push rods (0.4mm Nickel-Silver tube).
    Spark plug ignition leads ('EZ' black line).

    Hi all,
    All of the flight surfaces of the kit parts (wings, tail plane, elevator, ailerons, fin and rudder) have heavy and pronounced ribs, which will need sanding down.
    These rib tapes caused rippling along the wing leading edges, which also needs to be removed.
    Lastly, the internal metal reinforcing rods do keep the resin wings from distorting.
    However they are very close to the surface and the ends have broken through the wing tips.
    So filling and sanding required,

    Quite a challenge, Mike @sandbagger
    Lots of work ahead.

    Yup, some filling and sanding ahead, my friend @sandbsgger. Looking forward to the final looks!

    Hi all,
    Well I'll start with the flight surfaces.
    I've sanded down all of the over scale rib tapes on all of the flight surfaces.
    I've also filled then sanded where the wing internal support rods protruded from the wing tips.

    The tail plane locating recess on the rear of the fuselage has two huge 1.2 mm diameter holes.
    I assume these were intended to be used to locate the tail plane onto the fuselage.
    However, the underside of the resin tail plane has no locating stubs and is smooth.
    To ensure the tail plane located correctly, I resorted to inserting 1.2 mm diameter tubes into the fuselage holes, with 0.5 mm diameter rods fitted in the tubes.
    I drilled the locating holes through the tail plane and fitted it down onto the rods.
    The fin is just a butt join to the top of the tail plane - not good.
    So I drilled two 0.5 mm diameter holes in the base of the fin, so it could be located onto the protruding rods.

    The rudder is also a butt join the the rear of the fin, so these were drilled and rods inserted to support the rudder.
    I did the same to attach the elevator to the tail plane, which enabled me to angle the elevator down slightly.

    The 3D printed tail skid support and the tail skid are again just butt joins.
    Therefore, I drilled and pinned the tail skid to the bottom of the rudder post on the support frame.
    This should provide a sturdier joint for the tail skid.
    Also I has to sand down the over-scale thickness of the tail skid to a more 'in-scale' thickness.

    The lower wing halves are intended to have rods fitted to support them in the fuselage.
    Whilst the wing roots can be drilled far enough to add sufficient rods, the amount of fuselage support is minimal.
    Drilling to far into the fuselage means you'll hit the cockpit internal structure or components.
    The wing rods are good enough to locate the wings into the fuselage.
    But I think most of the wing support will be from the adhesive joints between the wing roots and fuselage.

    The upper wing halves are intended to be joined together using inserted rods, which pass through holes in the top of the 3D printed cabane struts assembly.
    However, the spread of the printed cabane struts is too wide to fit into the fuselage recesses.
    Pressure needs to be applied to get the struts located and given how brittle the printed resin is, they could break under pressure.
    Also the ends of the struts are not shaped to fit into their locating recesses in the fuselage.
    I reshaped the strut ends and managed to drill and pin the struts onto the fuselage to hold them in position.

    So now it's onto sorting out the upper wing installation.
    Pretty good for the kit only cost 145 GBP ?

    Awesome job on this VERY challenging kit, my friend @sandbagger! Amazing extra works to cater for the kit's idiosyncrasies.

    Hi all,
    Again, a problem to overcome.
    The interplane struts are 3D printed so have no internal support rods.
    Also, they have no end locators.
    However, the upper and lower wings have locating recesses.
    I assume the original intention was that rods, from presumably resin struts, would use these locating recesses.
    So I drilled 0.3 mm diameter holes into the end of the struts and added Brass locating rods.
    These will hopefully provide better location for the 3D printed interplane struts.
    That is assuming that the brittle resin struts don't break during assembly or under the weight of the solid resin upper wing halves - we'll see,

    A great idea to add those brass rods, Mike @sandbagger
    Let's hope the strength is sufficient.

    Hi all,
    The upper wing had a dihedral angle of 3 degrees, the lower wing was horizontal.
    Test fitting the upper wing revealed that the cabane side support struts were too short.
    The interplane struts fitted correctly.
    Therefore I removed the two rod support lugs on the 3D printed cabane strut assembly.
    I then drilled and inserted 0.4 mm diameter rod into the top bar to give the required wing half separation.
    This allowed the upper wing to be slightly lower and rest on the cabane top bar.
    The upper wing test fit after this was correct,
