Marklo Posted December 20, 2022 Share Posted December 20, 2022 (edited) Ever since I finished my Oertz I’ve been itching to build one of these a triplane floatplane what’s not to love. Now there are one or two issues. I can’t find a scale plan view of the triplane however it was based on the biplane for which I do have full plans and I know the wing surface area and chord width so between that data and the pictures of the plane I can make a good guess at the span or the three wings. Next step scale the plans and figure out the wing details. Well first up clear out some of my wip and wait till January the 7th Edited May 11, 2023 by Marklo 18 Link to comment Share on other sites More sharing options...

Marklo Posted December 20, 2022 Author Share Posted December 20, 2022 (edited) Sf4 biplane hacked together with the triplane side view and scaled to 1/48. I’m assuming the triplane wing is of the same shape assuming the biplane just with a narrower chord. Now I just need to figure out the wingspan based on the chord width and surface area and three equal wing spans.

Marklo Posted December 20, 2022 Author Share Posted December 20, 2022 (edited) A little algebra gives me this equation ( yes I know I’m not allowing for the tapered wingtips and radii, but it’ll give the approximate midpoint if the wingtip) and I just need to find the area figure in my WWI seaplanes book pop it in and I’m approximately there.

Marklo Posted December 21, 2022 Author Share Posted December 21, 2022 (edited) And the magic number is 28.68 m squared giving a span of 8.5m or 178mm in 1/48 I’ll allow about 4mm per side for the tips which gives me a span of 186mm Edited December 21, 2022 by Marklo 3 Link to comment Share on other sites More sharing options...
Toryu Posted December 21, 2022 Share Posted December 21, 2022 A many-challenge project Marklo! It will be great to follow. Modelling not often (but sometimes) starts with calculating - e.g. 'will I get it done within the GB timeframe'... 1 1 Link to comment Share on other sites More sharing options...
TonyOD Posted December 21, 2022 Share Posted December 21, 2022 I find scratch build projects of this nature quite remarkable. 1 1 Link to comment Share on other sites More sharing options...

Bertie McBoatface Posted December 28, 2022 Share Posted December 28, 2022 Yes, it's a sleek looking aircraft to be sure. Have we seen you do a triplane before, mark? Link to comment Share on other sites More sharing options...

Have we seen you do a triplane before, mark? Well I did do a Sopwith Snark and Pfalz DR1 And I have build a few quads too. The Wight The Supermarine PB31 aka the nighthawk. And the Oertz W6. Although the Oertz is probably more a double biplane than a quad. Edited December 29, 2022 by Marklo 4 Link to comment Share on other sites More sharing options...

Marklo Posted January 8, 2023 Author Share Posted January 8, 2023 Time for some woodwork And we have a fuselage buck. I really love my scroll saw 7 Link to comment Share on other sites More sharing options...
Marklo Posted January 13, 2023 Author Share Posted January 13, 2023 A quick molding session and I have a fuselage. I’ve split it horizontally rather than vertically as I find that makes the cockpit and engine openings easier to make. 4 Link to comment Share on other sites More sharing options...

Marklo Posted January 17, 2023 Author Share Posted January 17, 2023 (edited) starting on the buck got the floats. I must go down to the sea again, to the lonely sea and the sky; I left my shoes and socks there - I wonder if they're dry?

Marklo Posted February 21, 2023 Author Share Posted February 21, 2023 Now that the Armoured car and Ju88 GBs are done the salty sea dog is my main priority so the Sablatnig is back in the bench. I wasn’t happy with my first em set of molds so I went and plunge molded a set of fuselage parts. The Sablatnig is slab sided so I’m attaching flat sections to the sides to get the right effect. 4 Link to comment Share on other sites More sharing options...

Marklo Posted March 12, 2023 Author Share Posted March 12, 2023 After much toing and froing I finally used my blue stuff and resin cast a pair of floats, which I’m happy with. 3 Link to comment Share on other sites More sharing options...
Marklo Posted April 1, 2023 Author Share Posted April 1, 2023 That’s the cores for the wings sanded to aero foil shape and the skins lined cut and folded. I need to bend the cores then I can assemble the wings. That means that excepting the tail and turtle deck all the major components are done. I should actually be able to get quite a lot or the assembly done next week. 4 Link to comment Share on other sites More sharing options...
Marklo Posted April 4, 2023 Author Share Posted April 4, 2023 Went molding again finally happy with the turtledeck. Need to do the interior next then this should all start to come together fairly quickly. 2 Link to comment Share on other sites More sharing options...
