Build-Off II - Potez 621 'Dunkerque'

At the risk of having 'jumped the gun' from most of the world (it is December 1 here), here is a possible entry into the second build-off. Whether the subject gets completed in time is, of course, in the lap of several gods

The Potez 540 is a '30s French bomber of no great reknown and will probably only be remembered as serving on the losing side in the Spanish civil war!

It is a typical lumbering European bomber of the period - lots of glass, small bomb load, a monoplane and strangely - retractable U/C!

As a model, it should be fairly easy to design, build and fly. High, simple big wing, rectangular X-section fuselage, no flaps, and with retractable U/C.

About the only problem area is the complicated arrangement of the nacelles and their attachment. Something interesting to solve.

I intend to do a 'design-as-I-go' build using the dreaded CAD but only as documentation. It would not be worth laser cutting anything as I doubt anyone else would want to copy such an ungainly beast!

Still a few things to do before a start is made but hope burns eternal

If there's a prize for ugliest aircraft, you'll surely win! An unique choice! Bonne chance!

Now there's a thought someone Trouble is, Tim Hooper might come out from hiding and it would all be over!

OK Pat, you win. Just because you're almost the first ones over the date line

And, yes, it is ugly. I think it would take a "hooper" plane to get uglier

It cant be THAT ugly, someone made a plastic kit of it a few years ago (which I have). One of the characteristics I liked were the nacelles - almost always polished aluminium, irrespective of camoflage!

Joe - you beauty! I was hoping this might bring a few unusual types out of the woodwork
The Bloch and Amiot etc were certainly not pretty!
Thanks for the colour pictures - one of them 'D' may well be my scheme from the Spanish war.

Not the ugliest, the ugliest was the Farman Jibaru, Tim Hooper built it and made it look sorta good.

My hoped-for version of this beautiful aircraft works out at about 60" span. This was determined by scaling to suit GWS 9X7 3 blade props and 3" diameter wheels - as good a method of determining size as any

A couple of 400-class outrunners should be ample with a weight of around 3 lb including a Polyquest 3300 3S LIPO.

Construction will be balsa and ply and covered with Litetex plastic film. I have a set of Spring-air mini retracts that were originally destined for the HS-129. That should be fun as I've never used retracts before.

I've drawn up a plan for the fuselage and nacelles but with only enough detail to give me a start. Just a bit better than building over the 3-view as I was going to do.

Go Pat go! Yes it's ugly, but it has a very 'flyable' look to it, I think

When you've built and flown it, get it laser-cut and send the proto kit to Peter to build - see how he likes being lumbered for a change!

Is the wing of the full-size aircraft metal-skinned, or fabric covered? Hard to tell from the 3 views.

Bloch 210

there is a nice rubber powered plan of the very similar Bloch 210 here:

flying streetcar

Is it done yet?I am starting a new thread on my build the Bloch 200, which only a mother could love.I am convinced that the original design was made so streetcar companies would have something to do in slow times.Joe

It's odd how Marcel Bloch (German surname) changed his name to Dassault and started building much better looking aircraft! I wonder what would have happened to Claude Dornier if he had changed his name to a German one?

That's the only way to build. I take great pride in building that way.
You build a lot more planes that way too. I'd never build anything if I had to plan much.

It also ensures the "exclusivity" of your builds, since even YOU can't build another just like it again.
