After downloading the instructions and additional diagrams for the build from Outerzone I was able to crack on Tuesday evening. As I started the build I then discovered a couple of other bits of balsa missing from the kit but fortunately had them to hand in my cupboard so no further delays.

Fuselage went together fairly well but discovered that the laser cut parts are slightly bigger than the plans, which is an issue considering you are supposed to build over the plan. Also, as the build moved on, I discovered that the drawings on the plans are slightly different scale too, so the jury struts are wider than the fuselage, the rear end doesn’t quite match up to the size of balsa stated to use or the actual fuselage position stated etc. No major issues just slightly challenging to my paitence.

However, my biggest issue at the moment and one that has caused me to down tools in frustration on more than one occasion this weekend is that the original kit came with pre bent wires and this one does not. Shouldn’t be an issue if you can measure and bend to the plan, but this is not what the plan was designed for and therefore the wire shown is only representational and I have wasted my wire supply on guesswork of lengths and angles for the wing struts. The jury struts also get othe way whilst trying to bend, present, re bend etc. At this point I will stop this part and look to try the wings build over the coming week. If anyone has a top tip or two for making these struts more easily I am happy to take advice. Ideally if someone has this kit unbuilt, could you provide me the lengths and angles etc of the wire bits? I can only but ask and hope.

Ok a quick update for this last weeks effort. Managed to sort the wing cabane in a fashion using spade connectors and wire. Seems pretty sturdy when motioning it around in the living room.

Building the wing had the usual slight size difference in laser cut parts and plan scale, but all over come fairly simply. The biggest issue was the 2 wing halves been 5mm different in length. Discovered this when deciding to build the wing upside down to give a level upper surface like I believe the real wing was. As you can see, the ribs were misaligned so had to do some additional cutting and trimming as they went together. Ultimately I think it looks fine and once covered should look a lot better.

Ok, wing is now assembled and covered with servos in place. It attaches to the cabana struts securely and passed my wave it around the dining room test. Undercarriage wires are bent and wing formed from old balsa stock as it wasn’t on the kit. Seems to be taking shape slowly. Shame I can’t get any scale wheels, so these foaming will have to do and see if I can make them look a little better by adding some bigger hub disks.

Yes, this will be electric, though not sure how to fit it all in just yet and will probably have a limited battery size to keep weight forward. Connector are just simple electrical spade connectors (blue) from Maplins that I drilled slightly bigger holes in to fit the screws through.

I can't rfemember. What diameter are the wheels, I have a brand new pair of Flair 3 3/8" (85mm) wheels you could have. PM me if interested.

Actually just realised. they have been used and drilled out to about 10 SWG but still in excellent condition.

Thanks gents, the axle is 12swg so your offer of the Flair wheels Peter I think the holes will be too big. Just checked another kit I have yet to start and that is 1/6 scale and requires bigger dia (4 3/8) so no thanks.

Useful link to DB thanks Denis, may just have to slash out on some decent wheels from there.

You can always bush them out with 10 SWG brass tube

I must say Peter, good move

With flying off grass, I always bush out wheels, for free running

I did add "Seal those wheels as they are heavy when soaked " John O/T

Of Course I should have said "Bush them with 12 SWG tube"

Most wheels have an 8 SWG hole but I find that bushing them with just a simple piece of tube works perfectly.

There is an added bonus. If you solder the tube to the wire and extend it past the wire you can drill through the tube and hold the wheel on with a split pin and washer. You never lose a wheel but can take them off easily. Looks scale too!!

Ok, so today's update shows that I have been a little more creative and added some covering and colour to the model so far built. I know that some of you will groan, but as said earlier, this model is for aesthetics and not pure accuracy. I have elected to use the 4 colour scheme that can be seen in an early post and is used on modern replicas of this aircraft; I'll also probably try to find a modern civilian pilot too. The tail is covered with solarfilm:

img_1509 (edited) (2).jpg

The wing was covered in light brown tissue (sheet balsa too heavy and a bit of a faff when tried) to give it the base plywood look, then I casually applied the green, mocha, azure bue and violet (Lifecolour paint) then coated it with satin varnish for a slightly shiny look; hopefully to reflect how the replica wings look.

img_1516 (2).jpg

img_1517 (2).jpgThanks to Peter for the wheels you can see in the background.

I've also had some good communication with the Vintage Model Company (Hadi) about this kit this week. From my experience so far, they will now fix the laser cut part sizing issues and make it clearer that wheels and pre-bent wire parts are not included in any future kits (short kits) which is great because anyone wishing to build this nice unusual model will still have a very good starting point without the hassle of cutting ribs etc. I wanted this model because I have never seen one been flown at any club I have been a member or visited.

So now onto the power system...

Very interesting thread Simon. I had a look because I am after finding something to build for the unexperienced. At first I thought I had found the kit until I see your issues. I realise "building" includes these issues and part of the hobby/enjoyment but don't these kits get built before they get released? Not everyone as the experience to fettle them.Another kit for me to avoid. Would love to find a good laser cut kit.

Hi Sid, yes this is definitely not for the inexperienced, but I can strongly recommend the last kit I made and added to a thread for; the Super Flying Model (SFM) Fokker DVII. It is easy to build, good clear instructions and fits together easily. Have a look and see what you think.

Assistance if I may please?

I would like to use a motor, ESC and batteries I have already and think they should work but just after a second opinion. Current bits are: 960Kv 480 size brushless, 30A ESC and 11.1V 1300mah batteries (best fit as can go vertically against fire wall. Larger mah too long). Prop size tbc.

I have just weighed the model as it is and she is 800g. That is everything except the fuselage final bits of balsa and covering. May need some lead up front too, so my best guess is to make the model AUW to be max 1000g (35oz).

Wingspan is 46" with an average width of about 8"

Max prop size would be 12"

I'm not looking for sport performance, but enough to do basic aeros and have a flight time of at least 5 minutes.

Any thoughts or concerns gratefully received

Hi there,

The O.S. OMA-3815-1000 Brushless Motor is a good match for this model. It's equivalent to a 2.5cc glow engine, which is the maximum sized engine recommended for the model.

Hope you all had a good Christmas break. Model was banned from the dining room due to it being needed for the numerous family and friend gatherings so there has been a bit longer between updates.

So, how is it going now? She looks like a Fokker now, but until her maiden, I won't commit to her being an EV or DVIII, lets see how the wing holds out.

Fuselage went well though sheeting the front end was a little fiddly with my struts in the way. I also decided to use stringers on the rear upper surface to reduce some weight; that was an easy task

img_1535.jpg

Managed to cut the cowl relatively easily with scissors and a micro saw. It's not perfect but reflects well enough. Too add a little more to the vacant space up front and a little nose weight, I used a 3D printed radial engine from Inwood Models. I like it.

img_1533.jpg

img_1542.jpg

Then the more relaxing part of the build, the covering. Using my printed Lozenge tissue, the sides covered well with several coats of dope and I used light brown over balsa ready for painting the Olive Drab.

img_1545.jpg

img_1551.jpg

After refitting various struts and parts I further added to the mix of decor with some eyes up front and added my own made decals at the rear utilising Solartrim. I just needed to satin coat them to gett rid of the gloss shine and she'll look better.

img_1552 (edited).jpg

I will probably add a pilot once I know she flies; hopefully! Until them I decided to cover the underside and made a hatch that removes very easily but which stays in place with the help of a good magnet and some frictional restraint. This was all covered in further home made Lozenge. You can really see the splash and contrast of colour and patterns now.

img_1561(1).jpg

img_1651.jpg

img_1652.jpg

So she is all built and I'll get some full model shots outside when it stops raining. There are more photos in the album to show the pushrod routing for the rear surfaces and other bits. All up weight with everything (incl battery) is 978g which I am very happy with. CoG, if it is still the same on my model compared to the plan, is almost spot on and we have a good slightly nose down attitude. Pilot may level her off a little more.

So, I need to de-gloss the decals and waterproof the underside of the fuselage and then hope for good weather soon for the maiden. I'll post pics and maybe a short video when that happens.

Till then, wishing you all a Happy New Year and more builds to come.

Thanks Peter.

Just following up from previous discussion regards wing colours, I have done a little test with mine. First picture is how she is with 2 tone upper and lower in colour then I put it into black and white to match the only photos we can find of this aircraft. It is very difficult to spot any colour change on the wing surface so it could be assumed it is all one olive drab colour as the cowl and uc wing. Either way I think both work but just like this colour mix
