Default Am curious if the Belphegor has been built before

For a long time, I have been curious about this particular aircraft, if anyone has built a model of it before.

I'm referring to the WSK Mielec M15 Belphegor biplane, the only turbine powered biplane(the 1910 Coanda notwithstanding) ever built.

And, like its namesake, it was big and noisy.

And it was almost ugly enough to stop a computer.

But, in amongst other projects(such as the Sanka fighter), I've started to kick around the idea of taking one of the 77mm ducted fans I have and trying to scale up the drawings I have on the Belphegor(including one profile of a Boeing Belphegor, in which someone with too much time on their hands decided to see what an unnatural union of a Boeing Vertol Chinook mated with a Belphegor would look like, the results being as bad as you might think), and scaling things up until I have something that could approximate an RC model.

But, as this design has been around since the 70s, I'm pretty sure that someone else might've gotten the idea to turn this into an RC scale project, and am curious about that.

Because if someone else here built one, I wouldn't mind trying to pick their brains a bit to see if I might be going in the right direction, design-wise.

There would appear to be enough pictures and 3 views on the net to make a reasonably accurate Belphegor but it would have to be built pretty light if you wanted to keep a scale inlet and exhaust. The high aspect ratio wings would help but those huge wing mounted chemical hoppers would do nothing for the drag!
It would certainly turn a few heads at the field.

No, I'll have to try something, because if I simply scaled up the drawings to fit the 77mm ducted fan, it'll have a 92+ inch span for the top wings, and a 62+ inch span for the lower wings, and I was hoping that it would scale up to around a meter span at most for the top wings.

At a meter or so span, with the ducted fan, the intake would look decidedly out of scale, but, as I'd want to have this as more a fun flyer than anything else, then that will have to do.

Now, as to an olive drab Boeing Belphegor..............................

If you haven't seen the Boeing Belphegor, or even heard of it, here it is:

I've never heard of it, but I learned a new word in looking it up: sesquiplane.

You never heard of it before?

You must've led a sheltered life.

It's true. And I've even scratch-built an An-2, which I think qualifies.

Whatever you do, don't Google just "Belphegor" when looking for pics. You won't like the results!

Would you ever want to attempt to build the Lala-1?
