Peter Miller Posted January 25, 2015 Share Posted January 25, 2015 In about 2002 I saw a picture of an aircraft in Aeroplane Monthly. I took one look and thought, "That was designed by Col. Bowden." Aeroplane Monthly very kindly provided a 3 vview from an AEROPLANE of the era, about 1932. The aircraft was a side by side two seater cabin aircraft called the Peyret Mauboussin Type 11. A French pilot called Rene Leferve flew it from France to Madagascar and back, no mean feat. He then flew it from France to Saigon in 10 days flying 12 hours a day. He then flew it back rather more slowly. THis little aircraft was powered by a nine cylinder Salmson AD9 providing a mere 45 horse power. The wings had no struts and featured full span ailerons which could dbe drooped as flaperons. I designed and built a 57" span model powered by a geared Speed 400 motor. I am now starting building a 1/6" scale version for an SC 30FS. 76" span a bit over 600 sq inches of area. It will be like a powered glider in effect. I am sure that many people will be delighted to know that it will be ideal for electric power. Here are pictures of the original plan that was published by Sailplane and Electric in the USA and photos of my model. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted January 25, 2015 Author Share Posted January 25, 2015 No, it flew like a dream. Even used some very slight slope lift to good effect. Actualy the moment arm is a full chord, quite enough. Tailplane is relatively large too.

Steve Adams Posted January 26, 2015 Share Posted January 26, 2015 Very Nice Peter, Quite a lightweight model I would say,just like your Velie Monocoupe free plan in Radio Modeller in the 90s I remember. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 27, 2015 Author Share Posted January 27, 2015 Yes, Steve. IT should be very low wing loading indeed. Unfortunately this week I have so much on that I don't know how much I will get done. but I will do some. Next week should be better.

Peter Miller Posted February 3, 2015 Author Share Posted February 3, 2015 Well it has been a bit of a hectic spell but managed to start building the Peyret M. Fuselage sides with doublers added and the rest of the fuselage parts. This shows the sides already bent and ready for final assmebly Because the fuselage sides are bowed considerably I glued on the doublers and quickly assembled the fuselage and clamped it in shape pulling the front in. The longeron under the left side windows was a bit too stiff and snapped but the main loads are taken by the doubler. Once the dobler had dried I took it all apart and assembled the sides to the big formers F-3 and F-4 and left it to dry. Then added all the other formers and cross bracing. Just make sure that the fuselage stays straight over the plan view. Side window frames also added. This is the front of the fuselage where the engine mount will go. This picture shows how the snake outer tubes are supported. View showing the slot for the tailplane and the fin. The latter goes right down and is glued to the tailplane. The sheeted under side. The undercarriage mounts are made with a lamination of 1/8" Ply and two strips of 1/8 Liteply. The U/C will be held on with flat saddles. If you can build a vintage model you can build this.

Peter Miller Posted February 15, 2015 Author Share Posted February 15, 2015 While waiting for my ribs to arrive I built the dummy engine. THis a loose impressionist item, not an accuaret scale engine. This is because the first time the modelo noses over it will get damaged. The cylinders are made from balsa dowel. The string is wrapped round doubled up and then one layer is removed to give even spacing. The crankcase is two formers with 1/8" balsa warpped round and then a layer of 1/64 ply on top of that. The rockers are just little scraps of 3/32" X 1/4" spruce roughly shaped. This is a dry fit of one cylinder with wire pushrods fitted.. The engine complete. The exhausts and inlet tubes (Not visible in this view) are just made from snake inners heated and bent at right angles. The cylinders should be tapered fro the top. A picture of th e actual engine can be found if you search for Salmson AD9 in Wikipedia. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted March 14, 2015 Author Share Posted March 14, 2015 Well what with several interruptions and a lot of other hassle at least I can add some more to the build of this model after a month. The right wing and centre section on the board. Nice ans simple. THis is the centre section, the wings are joined to it with a SLEC alumnium tube and paper tube in the wing. This shows the root of the wing and the full length aileron. The wing is almost complete, just needs the sheet at the root and the capstrips adding. THis is the wing tip, again pretty simple. The sheeted centre section The underside with the holes to pass the servo leads through. The centte section being tried for fit. Note that after covering the centre section is glued permanently to the fuselage. The hatch in the bottom is big enough to get ones hand in to do any work needed and thred the leads through. The tail unit is very simple indeed. Don't be tempted to make them out of sheet, you need to keep the tail end light. This is the basic undercarriage. The lugs by the wheels are for the dummy shock struts. The model is now ready for testing. Quote Link to comment Share on other sites More sharing options...
ROY DAVIES 1 Posted March 14, 2015 Share Posted March 14, 2015 It's a chubby little chap Peter but very appealing. Worth a punt I think and you like me build em' to stay together. I'll have to tidy up my 'Summer shed' and get ready. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 20, 2015 Author Share Posted April 20, 2015 After waiting for weeks for blue skies AND caalm weather I flew her yesterday in spite of the clouds. 76" 4 1/2lbs, SC 30 FS and she took off up hill and flew like a dream. Some poeple have said that she would be twitchy. Not a bit of it. Rock stable. THrottle back and pull in up elevator and eventually one wing will start to sink slowly. On the second flight she was put through loops, very slow and stately, even consecutive loops. Rolls are slow and stately too. Inverted is not possible. Various other highly non scale manoeuvres were flown and she never tried to bite once. My friend who flies my models for the camera has already asked if he can buy her when I have finished with her.!! If you want relaxing flying on a Summer evening you can't beat this one. Oh yes. IT is perfect for electric conversion. It won't sound right which it does with the little four stroke burbling away but it would be so easy to convert. Don't ask me what you need for the conversion. I don't know. Edited By Peter Miller on 20/04/2015 09:17:44 Quote Link to comment Share on other sites More sharing options...
Jimbo565 Posted April 20, 2015 Share Posted April 20, 2015 Very nice Peter, one for the future methinks. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 20, 2015 Author Share Posted April 20, 2015 As soon as we get calm weather AND blue skies it will be on its way. It can even be fitted onto a full size plan sheet without too much trouble. I have done the layout. GRaham Ashby loves it. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted April 26, 2015 Author Share Posted April 26, 2015 THanks. Yes. I feel that it really has a character all of its own. IT also flies better than a Cub. Much more positive Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted June 8, 2015 Author Share Posted June 8, 2015 At last, after waiting since before Easter we got calm weather, blue sky and sun and my pilot for when I wantbto take photos. Now you can see the Peyret Mauboussin in all its glory, Flies like a dream and was even trying to thermal a but Quote Link to comment Share on other sites More sharing options...
