Good to hear you are back to “work” Bart. I remember many late nights as I was designing my Bearcat in 3-D, checking and rechecking the design from multiple angles under different surface and lighting conditions, yes those were good times I’m sure your result for the Buffalo will be great..

There comes a point when you must stop collecting more references, and proceed with other things.

Spend many hours to get the canopy as good as possible. I'm really happy with all the pictures provided my mr Casius, they are very helpful.
Also Jukka's pictures are helpful.

Result so far, time to move on with the tail and wings.

Your canopy looks very good. I'm sure it was challenging! Keep up good work!

Thanks Jukka,

More cad work is being done on this Dutch Buff. Made a floor below the rear part of the cockpit glazing. Also test fitted the .stl panel that Jukka sent me, looks nice and gives an idea of things to come. With the basic shape of the fuselage ready i made a start with the wing. The idea is to use the original airfoil.
So I traced the outlines of the original drawings on top view and front view and oriented them in the 3d environment. Now using the dimension as listed on the dimension drawing the airfoil sections and tracings where scaled to fit the 'box' I made. At this point all the lines match and the 3d curves can be made.
When the framework was done the surfaces were created using the command ''curve network'. I gave the trailing edge 1.5mm thickness as this should be practical when shaping the wooden edge.
I'm note sure if i will go for a 3 part, 2 part or one part wing. For now I'm leaning towards a two part wing.
With the basic wing shape done the 1 degree incidence was made by rotating the wing hollow shape. Next up are the ailerons and flaps.
Also i made the ventral window in the fuselage underside.

Time for another update . . .seems very silent here in the Giant Electric Planes forum, should i move this thread to another part of RcGroups?
Have been busy with the tail surfaces. Had some trouble in getting the shape to look just right but after several times starting from zero the looks are OK.
Next up are the flaps and ailerons, when that is done the fun begins with the landing gear

Really nice modelling Bart. With the original drawings to work from, I can see how it would suck you in.

I have a feeling that it is a bit quiet at the moment generally. I'm inclined to think your thread might be better in the Scale forum unless you want to attract input from people who have specific experience in the design and construction of large models.

Incidentally I have today been trying the technique for glassing you outlined in the Do24 thread, wiping off the excess with kitchen roll. I'm really pleased with how it has flattened a multi-layer covering for a wing joint and how much resin came off. So thanks for that,

All the best

Hi Bart,

Wherever you choose to put your thread I'm watching! When I start my Do 24 thread it will be in the scale forum. I think there are more builders watching there.

I am one of the, no doubt many, silent followers of your amazing design work and I only found your thread because it is in a forum that I frequently visit. However I do understand why you are considering moving it to a location with a potentially more "appropriate" audience.

If you should decide to move the thread, do you know if our thread subscriptions will still be valid? If there is any doubt can I just respectfully suggest that you post confirmation of the new location here a day or so before the move so that I, along with others, will know where to re-subscribe if it should be necessary.

I really would not like to miss out on updates as this ambitious project develops.

Yes, subscriptions will still be valid, they move with the thread.

Looking forward to see what you work out for the landing gear Bart.

Thanks for the kind words guys, i see there are still many people following the project so there is no need to move the thread for now.

While the design is still in the early stages i'm slowly gathering all the hardware for the Buffalo.
For this bird I will be using Futaba's S-Bus system.
