Hi,

Possibly the smallest helicopter in existence, this 80hp Brondetti two-seater was exhibited recently
in Rome. Intended range is 640km, but whether it has made its first flight is as yet unknown.

The Dornier Do 32 was even smaller, and if you start looking at unmanned helicopters - well, you get the idea.

Also check Hoppi-Copter , Hiller ROE and Gyrodyne RON.

Hi Arjen :)
This small heli has been bothering me for many years. I have seen it described as a design of Mr. Frederico Brondetti with involvement of Count Ettore Manzolini and Mr. Gianini. (BGM-2 = Brondetti, Gianini, Manzolini.?)
However, on youtube.com/watch?v=-3is9F9DvgA this heli is called the (Fernandino?) Bordoni BGM-2.
And.... there could be a connection with the MGP-2 Libellula (I-MANN) which may or may not have been
known as the BGM-1.
Can anyone help me stop bothering?

I am aware of several helicopters which apparently Mr Manzolini was involved in. However I have problems with precisely name them and put in context.
The names I know are Libellula - Libellula IV, and the BGM-2

HELI 1: For starters BGM-2:

In the last pic, however, it is called BGM-2 Libellula (screen from the L'Ala 10-31 Maggio 1950)
Some say that BGM stands for Brondetti, Gianini, Manzolini, however the first guy is most likely Mr Bordoni.

HELI 2: This one I found to be called Libellula:

HELI 3: Known as Libellula II is (was) presented at the Museum Caproni.

HELI 4: In couple of places can be found as Libellula III:

HELI 5: Libellula IV - this one is mentioned in the book: Helicopters and Autogyros of the World by Paul Lambermont. No pictures available to me.

HELI 6: This one is the most disturbing for me. In the video it is called just Libellula by Manzolini. But it is a two-seater - so matches the Libellula III descriptions, but is different and resembles the general layout of Libellula II, although it has more front windshield panes, single fuel tank and V-shaped empennage.
