|Thread: BFW M23c - Golden Age German Racer.|
I believe so!
I took the model down to Headcorn last week where Graham Ashby took some pictures of it enjoying the beautiful Kent sunshine!
It was a bit murky this morning but the wind was straight down the strip and, with no valid excuses remaining, I got some fresh air under the M23c's wheels. Happy to report an entirely uneventful test flight, followed by two more. Three clicks of aileron trim had it flying hands off very nicely indeed! One happy model designer here!
They do look very similar don't they? I did consider building a Klemm when I designed this but decided against it as there seem to be quite a few Klemm models but not so many of the M23. As for the engine, there was an M23c with an inline engine as well.
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.
Thanks Torsten, I'd be interested to know whether people prefer the single seater or twin seater version.
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.
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.
Not a great picture but this shows the state of things at the moment.
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.
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...
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!
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!
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.
That is very nice indeed! Thanks for posting those - I'm going to have my work cut out!
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.
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!
|Thread: Building Jim Newberrys Puddleduck|
Looks like a great day out DD, good to see the Puddleduck in the air!
With rudder/elevator models I always have the rudder on the right stick - the way I look at it, mode two puts the primary roll control on the right stick. With a four channel model this would be the ailerons but for a three channel model it will always be the rudder. Hope you get plenty more flights in over the summer!
Looks good DD! Hope the maiden goes well. I have to say, I like the brown paper dodge, I'm going to file that one away for future use.
|Thread: Tiger 72.|
Just to be clear about a couple of things - there is no revised F1. The kit is not supplied with one and we do not sell one. The model is designed for electric power only. If a builder decides to build a Tiger 72 for ic power then I am very pleased but it must be understood that the model is not designed for ic engines and, like any electric to ic conversion, the builder takes full responsibility for the modifications required. A small number of my customers have contacted me to ask about ic conversions and I have supplied them with a suggested alternative F1, free of charge and on the strict understanding that it is supplied as a favour and not as a kit component.
The correct location for the former would be determined by measuring the distance between the rear of the propellor and the rear of the engine mount. The alternative F1 supplied should fit in approximately the correct position but will need trimming to suit the individual installation.
Hope this helps,
