The Hummel Aviation Hummelbird

Well, I am looking at a new scale design. Hopefully more successful than the Aviat 110 Special.

The Hummelbird is an all metal microlight which is permitted low G aerobatics. For an "Unknown" aircraft there are masses of them Just check out Google search images.

The power is normally a VW engine cut in half to make a flat twin. You have the choice of taildrgger or Trike.

A 1/4 scale model will have a span of 54" which is about perfect for a .40 to.52 four stroke as a scale engine.

THis is one in military colors.

There is one in the UK in polished metal.

I can see that the fuselage may be a bit of a pig to design and build.

Anyway, here is hoping

Very pretty, but those tail surfaces lok a bit small.

Not one for Danny though (can't see any rivets). wink 2

Here is a link to a picture of the British built one.

Lots of rivets there

Tail surfaces should be fine. The tailplane is over 15% of the wing area, about the size I am using on most of my designs these days

Yes, the fuselage is going ot be tricky. Mainly getting the formers drawn so they match. Once that is done the buildimg will not be too hard.

Now, what I have to find is a block of pine about 16" long by 5" square to make the canopy pattern!!!!

Oh yes, I am going for a Yellow one probably with the extended wing tips. Tail dragger and no spats.

Hi Tim

I don't object to people converting my designs to electric. What ever turns you on.

No. I shall be using an O.S 40 FS Surpass or, if the wieght clims too hight I may go for a .48 Surpass.

The four stroke is ideal as it will look very like the VW engine, or rather 1/2 VW engine that most of them are using.

Of course I will have to make a dummy for the other side.

Wing area will be about 510 sq.in. possibly nearer 600 if I go for the Whitman tips.
