Well latest project has just moved off the old CAD and into the workshop, I will try to keep an up to date blog as things progress, the basic work and thought process is done so its time to start cutting ply and balsa. Not sure about the name yet so that might change. The model is based around those nice 1930 style light commercial aircraft and should be ideal for IC or electric but I am basing the prototype for an OS52FS.

Looks very nice Lyndsay - I like that period of aircraft as well, and as you know I'm a sucker for a biplane! And...I happen to have an OS56 FS Alpha as well.....Oh dear, I feel temptation looming in the future!

I can see my Maricardo losing its 52 Surpass to this little beauty!

It's very reminiscent of Tim Hooper's Waco, which I was  admiring on the "Biplanes" thread.

 Biplane ?? Am I missing something somewhere ? I can't see the other wing.............Mal.

Hmm, I thought it was a monoplane as well, and I'm the designer? It was interesting seeing Tim's courrier as it has many similarities and yet no connection, I hope it turns out as nice. For now I have enough bits to cut out without a second wing.

Ah, well looks like a biplane to me - then my eyes never were that good!
 
Looks like I'm safe then - mmmm, dunno though....

Lindsay,
 
That looks great - it has a bit of a hump in the rear fuselage which gives it character (as well as a bit of head room for the passengers).  Sort of a bit like a low-wing Stinson, if there ever was such a thing!
 
Think I'd move the wheels forwards a little though....

Thanks, Tim, to be honest the wheels or undercarriage have been a bit of a stumbling block as the original concept I had drawn up had retracts designed in but I decided I wanted this as a bit of a Sunday hack with scale looks so went back to a fixed u/c, they could certainly come forward a little without a problem, I have yet to finalise the mountings so its open to change but the basic shape is pretty much fixed now. I am tempted to go to Slec for the formers to be laser cut but I really want to get stuck into her across Christmas and New year so I think its down to the vibro saw and a bit of patience. First job is printing off al the formers now onto adhesive paper, and stick onto the timber ready for cutting, its a technique that saves a lot of tracing! I hppe to have her finished by mid March all being well.

I too feel that the u/c should be a little more forward . Love the design and happen to have a couple of SC 52 Fs 's Have to watch the weight of the rear end as well I suspect .? Don't know anything about CAD --Can you work out the C of G with it ?
Keep us informed !

Myron, concensus does seem to be that the uc should come forward so I can deal with that. There are mathematical models that I use for the cg independant of the CAD files I produce, hence its not showing on the drawing although it will be somewhere around the wing main spar, so yes weight at the tail end needs to be controlled, the stringered rear structure will assist with this and I could model a theoretical weight distribution based on some common data, but as we all know it will change in practice so its not worth the trouble in the end. I hope to avoid nose ballast, but if it needs it, it needs it so I'll just monitor things as I go.

As a general rule I believe that the wheels should be on an imaginary line at 35 degrees from the real C of G .Not necessarily the horizontal one that we all use ' Especially important on a bipe I would have thought  where maybe the weight of the upper wing has an effect on said C of G . Just my thoughts !

Err it's not a bipe, how come everyone thinks its a bipe? I thinks it because there is a little bit of staggerwing in it?

Would it be too much trouble to add another wing, just to keep us idiots happy?

Okay everyone.    
 
Have a closer look at the plans and you should see that what you all see as a 2nd wing (upper) is in fact a former and lines showing where it goes ( x3 places!!)
 
It is not a 2nd (upper) wing.
 
( I had to zoom picture up to note this to be honest!!!!!!)
 
Hope that settles that one!!

I thought it was a bipe 'cos someone else mentioned it ( passing the buck !)  Now I've blown it up I see it's not.of course .Should have gone to SpecSavers

So it's not a biplane then?  Blimey......
 
I'm looking forward to seeing this one take shape!

That looks really good,another one to put on the build list,got to get some more work done on the latest projects though.
The only thing is there is so much more work to do on a bipe though.
