Jim Newberry - Nuviation Ltd. Posted May 1, 2018 Share Posted May 1, 2018 I'm already at least six months late starting this one but here is my latest endeavour - a BFW M23c. The full size aircraft was a between the wars racer designed by Willy Messerschmitt, so it could be said to be the forerunner of the Me109 in the same way that the S6B was the forerunner of the Spitfire. If you look at the tail surfaces in particular, you can see they closely resemble the shapes that would appear on the 109. The wingspan of the model will be 78", making for a scale of approximately 1:5. The plans have been drawn up, the laser cut parts arrived a couple of weeks ago and I managed to make a quick start over the weekend. I really must crack on with things - I want to have this flying before the end of summer. So this is what I want to end up with... Full set of laser cut parts waiting to be released from their sheets. After a conversation with George at 4-Max, a suitable powertrain was ordered... Laser cut parts released and piled up. The edges need cleaning up to remove the bumps left from the sheets, but I have never found it necessary to completely remove the slightly burned edges, except where they will show through the covering. Tail surfaces beginning to be stuck together. It's a small start, but a start nonetheless! Quote Link to comment Share on other sites More sharing options...
Karl-Georg Krafft Posted May 2, 2018 Share Posted May 2, 2018 Here is my BFW 23 which I scratch-built based on the 3-view above. It spans 2,24m and is powered by a Saito 72. I would not dare to call the full size M 23 a racer. A two-seater with a 80 hp Siemens engine is more a sports plane or a motor glider. Good luck with the project.

Jim Newberry - Nuviation Ltd. Posted May 2, 2018 Author Share Posted May 2, 2018 Thanks Karl-Georg, if you can post a picture of your model I'd love to see it! As for the racing pedigree, the M23b won both the 1929 Ostpreussenflug and Circuit of Europe races, while the M23c was developed for, and won, the Circuit of Europe the following year - so it's not entirely unreasonable to call it a racer by the standards of the day.

Jim Newberry - Nuviation Ltd. Posted May 4, 2018 Author Share Posted May 4, 2018 The tail surfaces are complete in outline at least - they all need shaping in profile but I couldn't help putting them together just to see how they look so far. Fuselage work starts tomorrow. Quote Link to comment Share on other sites More sharing options...
Lorenz Mueller Posted May 8, 2018 Share Posted May 8, 2018 There's another one being built here http://www.rc-network.de/forum/showthread.php/669543-Messerschmitt-BFW-M-23-C-Projekt a bit bigger, and the text in german, but the pics speak for themselves. Yours looks like a fine project. Lorenz Quote Link to comment Share on other sites More sharing options...
Jim Newberry - Nuviation Ltd. Posted May 9, 2018 Author Share Posted May 9, 2018 Thanks for sharing that Lorenz. That is significantly bigger than mine and a stunning looking model! Mine will be more of a "practical scale" machine! Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted May 9, 2018 Share Posted May 9, 2018 Lovely plane Karl-Georg! Thanks for posting. I especially like seeing IC Scale models I also think the 4s engine sound adds so much more realism when flying too. Quote Link to comment Share on other sites More sharing options...
Jim Newberry - Nuviation Ltd. Posted June 18, 2018 Author Share Posted June 18, 2018 Well I have been steadily working on the M23c but the day job has been getting in the way a bit - now I have a couple of weeks off and hope to make some real progress on the model. This is where I have got to so far... Fuselage sides made up. Forward formers and battery tray added. Rear formers added, turtle deck planking complete. Tail blocks glued in place with a spacer to keep everything straight and I have bent a piece of steel to make a tail skid. The tail blocks have been planed and sanded to shape. Meanwhile, I have made up the battery hatch frame. The hatch skins have been soaked in hot water and are currently drying around this cardboard tube. I hope to increase the rate of progress over the next couple of weeks! Quote Link to comment Share on other sites More sharing options...
Jim Newberry - Nuviation Ltd. Posted August 29, 2018 Author Share Posted August 29, 2018 I have been a bit lax at uploading pictures but I have been slowly progressing on the build. For the last couple of weeks I have been working on the wing, although the work rate always slows down to a snail's pace during school holidays. The wing joiners are aluminium rods running into phenolic tubes, the tubes being fitted to the ribs through appropriately positioned holes. I had worked out the locations of the holes in each rib in order for the tubes to sit at the correct angle, but I was very pleased that it all lined up perfectly on the building board. The Multiplex plug can be seen in the root rib - on reflection, it would have been better if I had fitted the socket into the wing, with the corresponding plug in the fuselage side as the pins are a little vulnerable here but there we go - hindsight is wonderful thing! Servo leads run through the D box and are now waiting for the servo to be soldered onto the end. The wingtips are just blocks of balsa sanded to shape in place.

Jim Newberry - Nuviation Ltd. Posted August 29, 2018 Author Share Posted August 29, 2018 Just been painting a couple of finishing details for the model. Both are 3D printed items from Real Model Pilots with a 52mm hole down the middle of the dummy engine to fit around the electric motor. Strictly speaking, the engine is completely the wrong type but it will look fine from a distance. Quote Link to comment Share on other sites More sharing options...
Chris Freeman 3 Posted August 30, 2018 Share Posted August 30, 2018 Stunning project, well done, The laser cut parts look very well done, You must have great CAD skills as well. Thanks for posting this as it is nice to be able to see unusual projects. Quote Link to comment Share on other sites More sharing options...
Jim Newberry - Nuviation Ltd. Posted October 18, 2018 Author Share Posted October 18, 2018 I’ll have to ask you to excuse the untidy background but here we are this evening, only a few jobs left until the maiden! Quote Link to comment Share on other sites More sharing options...

Jim Newberry - Nuviation Ltd. Posted January 27, 2019 Author Share Posted January 27, 2019 In my last post I said that there were "only a few jobs left until the maiden".... Those few jobs have taken me three months to get around to finishing, but I finally got there last night. I made a second battery hatch so that I can swap between the two seat tourer version and the single seater with forward cockpit faired over for racing. While I was at it I also rebuilt the undercarriage as I wasn't happy with the first one. So here it is. I'll be getting some better pictures once the sun comes out.

Jim Newberry - Nuviation Ltd. Posted January 27, 2019 Author Share Posted January 27, 2019 Thanks Torsten, I'd be interested to know whether people prefer the single seater or twin seater version. Quote Link to comment Share on other sites More sharing options...
Jim Newberry - Nuviation Ltd. Posted February 9, 2019 Author Share Posted February 9, 2019 Laura Steele (soon to be Laura Newberry!) adds scale to the model. Finally a sunny day for photographs but much too windy to risk flying. Quote Link to comment Share on other sites More sharing options...

Stearman65 Posted February 9, 2019 Share Posted February 9, 2019 Looks very Klemmish? apart from the engine, although there was a radial engined Klemm 25. Quote Link to comment Share on other sites More sharing options...
