So here is a kit that I have had for a couple of years and thought it about time to put it together as a change to plastic modelling. When finished this should fly, which it will, but how often we shall have to see. I am not experienced in building Balsa models, I have build a small scale FW 190 and that was ok but it was never intended to fly it. This is summat different, it is big (1.66m Wingspan scale 1:33) and has a few more parts than the FW.
In order to build this aircraft I have had to first build a desk on which to work. This I have managed to fit it nicely in the corner of the modelling room. Then I made a start....it`s all glue and pins with cutting and sanding to get a perfect fit. The wood stock supplied does not comply exactly to the instructions but, as an engineer, there is nothing there that I cannot overcome.
It is a totally different discipline, am so far I am enjoying the challenge but I have a long way to go. I have no idea how long such a build takes and will still be building plastic along the way. I need to reduce my stash and get it under 200 models....running out of space you see.
I hope that this interests you guys although it is not plastic, I shall keep you informed:

I have built the odd balsa wood plane in the past but never attempted to fly them.
Good luck.
I think adhesives have improved and so it should go ok.
What glues are you using?
-
As recommended by the manufacturer I am using UHU Hart and Ponal woodglue. Both dry transparent and should do the trick. I used the Ponal on the FW and it has never come apart......but then again it hasn`t flown!
-
Just to clarify, I was with Kiteman when he bought this and not only is it HUGE (as was the real thing) but it is the MOTORISED version, not the glider so when ready for it's maiden flight, it will require the closing of the Autobahn route A2 for take off and landing.
-
So far so good, here is the Progress so far:
I reckon that when it is finished I should get it in the air, using the autobahn, before I reach Berlin!!! :o

Of course if things aren't quite right with a FLYING model, it has the potential to cause all sorts of issues that with a plastic model, you can fudge a bit. Hats off to you for taking on not only a flying model project but one on such a huge scale. You really do need the accuracy of a real aircraft builder to succeed with something like this.
-
I`ve got a bit more done on this mammoth beast and I must say that I am enjoying working with wood, tree wood that is ....it`s a nice change. The fuselage has finally come together after solving the problem I had with a "corkscrew twist" along the length that would have put the fin and rudder out by about 5 degrees. The tailplane and fin assemblies are virtually complete. The nose doors are in one piece and the battery box is half way there. I have placed the assemblies on the fuselage for photographic purposes only so that you can see where it is going. The tailplane and fin sit a 90 degrees to each other and the whole rear control surface assembly sits nicely now at right angles to the centre line of the fuselage. The front end of the fuselage has yet to be sanded to allow a perfect fit for the doors and the battery box / anchorpoint for the axles has yet to be finished and inserted into the fuselage.
Comments welcome.

That's a fair old beast of a plane.
-
a bit more progress on the beast. Up to now things are going together ok, I must keep reminding myself though that this will be a flying model and is not as detailed as a plastic model would be. I keep wanting to modify things and pack more detail in, but that means weight and that, for a flying model, is not good!
See what you think.

Hi Kiteman,
That is looking good. It will be a 'beast' of an aeroplane when built. You look to be getting on with it fine, and with some precision too.
Look forward to seeing more of it.

It must be real difficult to remember you're building a representation, not a scale imitation. Them 2 bladed props on aircraft that should have 3 or more have always raised my eyebrows in a cynical fashion but then, once they're spinning fast enough to take my head off, it doesn't matter. It's looking, well, GIGANTic!
-
Here is the latest batch of photos for you all to ponder.....
-
Sorry....here are the piccies.....

Wow! That last photo really shows the size of the beast.
I would not like to be underneath it if(when) it crashes.
Great stuff, I look forward to seeing it fly.
-
bluddy 'ell!!!
-
It's not just the wingspan that's astounding but the short body length in comparison. Of course with what it was designed to carry it would need long wings and once the aircraft is assembled, it won't be so apparent, but that last picture demands a sharp intake of breath!
-
You`re quite right my friend, if you look at the picture of the assembled model "wings roughly postitioned" it does not look out of proportion, but with the wing detached it seems that the wing is far too long...strange phenomena!
-
Of course when people actually meet you and realise you're only 3 foot tall, won't they be disappointed in the size of your "gigant"? yuk yuk
-
Kiteman, a whole 3 feet tall, Wizzel?
Now who's telling porkies.........................
Bigkev
-
Got a bit more done on the beast......wiring in the wing, servos and motor power cables....6 bloody motors on this thing...loadsa wiring, loadsa repetition work. Enjoying it though!

Hi Kiteman,
Looking impressive, keep at it.
Bigkev
-
Looking forward to test flight day!
-
Can you get it videoed, Kiteman?
We all want to share in the excitement.
Bigkev
-
Maybe a crash or two?
-
How cruel.... :(
-
They have no faith in you, do they?
Prove 'em wrong matey!!
Bigkev
-
Don´t worry Kev...I shall!
So the wing is planked as far as it goes and the ribs are all topped. The shape is now there and I can start on the problematic motor assemblies........more to come.

So now we have the Problem of the Motor gondolas. According to the plans the motors sit parallel to the centre line of the fuselage in plan view but in side view they have a declination of 3 degrees. The question is; 3 degrees to what? It certainly isn`t 3 degrees to the horizontal or to the wing bottom surface....it is 3 degrees to a dotted line on the plan which cannot be measured on the model itself. So how do I guarantee a 3 degree declination to a non existent Datum. Tony...you are an engineer...come up with a plan!!!
I have photographed the plan so that you can see what I mean. The wing does not sit horizontally on the fuselage either....it sits "nose up"
Waddaya think!!!

Engineer's of the World...................................... unite!
Is the 3 degree downwash based on when the 'Gigant' is sitting fully on its wheeled undercarriage?
Does that then compensate for the incidence of the wings in that stance.......................?
Only a thought from a mere mortal.
Bigkev
-
I had the same thought but unfortunately it is not the case. The datum for the 3 degrees, according to the plan, is a line that is not measurable in practice and bears no relationship to any datum on the fuselage that I can see.
-
Oh well just a thought.
I reckon You and Haddock will fathom it out.
Have you contacted the manufacturer and asked them?
Bigkev
-
by èck, you`re up early!
-
Can't be of much help. It looks as though the " datum " could be the line you would get if you sat the wing on a flat surface. Over the years, I developed a deep hatred for draftsmen who persisted in doing this sort of thing then sneered at you when you asked " what the bluddy 'ell is this supposed to mean". My drawings of course were superb.
Haddock.
-
mine too, I always tried to bear the end user in mind when designing or draughting anything. Unfortunately that is not always the case with other designers.
-
so after checking that the plan was accurate and re-draughting a few lines on it, I took the wing underside as a datum and transfered the down wash angle relative to this datum and came up with a 2 degree down wash from there. Then I build a jig that would position the motor mounts relative to the wing underside and at the same time hold them parallel to the fuselage centre line whilst the glue dried. It worked well and now I have my motor mounts correctly positioned on the wing structure, all the ducks in a row, one may say.

Thought it about time to update you all on the progress on the beast. Between mystery models and all sorts, I have managed to get a bit more done.

Hi Kiteman,
That looks superb. Its a big, big beastie.
When do think maiden flight will be?
Bigkev
-
I especially like the tactical blurring of the swastikas on the tail ;)
That's looking very nice indeed, I do like the paint job too!
-
yeah.... it took me ages to paint the garden like that.!
Re first flight... I hope to make it before the end of the season (Autumn)
-
on a slight aside, it's also good to see a recent pic of you too!
-
And so handsome too..........................
Photoshop strikes again maybe.................................?
Bigkev
-
Well now he's a respectable businessman he's got to look the part. Or maybe Doro's thumb's working its magic already!!!
-
Aaaaah Wizzel
I forgot about Doro's thumb.
That explains everything..............................
I have Christine's thumb to keep me right, if not her right hook!
Bigkev
-
Doro`s thumb ist not as big as you think, we get married on 12th June (in two weeks)....after that, who knows!!!!!!
-
Congratulations on your up and coming marriage.
-
Yep, I second that.
Hope all goes well and you have many loving and happy years together.
Bigkev

That's not you and Dave!!!!!!!!!!!!!!!
-
We've already had 30 years of each other's company - time someone else had a go I think!
I'm proud to announce that I'll be there in a official capacity too and I'd like to think that I'll be not so much losing a best mate as gaining a second one - both modellers to boot!!
-
Thank you all for you thoughts, Doro and I have been together for nearly 9 years now so we thought it about time to join us permanently together...no need for filling and sanding here....we fit perfectly together.

Too much information here!

Dont let your imagination run wild....ist only a metaphor!!!! ;)

Verified. They say "like poles repel" but although T and D have so much in common, I have never seen a couple so well matched.

Thank you Wizzel kind sir.
