Found in "Der Flieger", December 1964, a drawing of a brazilian helicopter design,
designated as"Abelha-1", shown without any other information, but in company with IPD

BF-4 (BF-2 ?) and Beija-Flor.

I'm not even sure, that it was designed by the same company. The number of helicopter
manufacturers/designers in Brazil may have been limited then, but judging the name and
suffix, it may well be from a total different source, maybe a kind of homebuild ?

Hi,

of course this design was related to Beija Flor BF series,if they wrote on it BF-4,from
CTA/PDI.

And what makes you that sure ? In the mentioned article just three drawings are shown, with
the caption "Brasilianische Hubschrauberentwicklung" (Brazilian helicopter developments) and the
designations of the three . Other types featured there are from Sikorsky, Westland and so on, so
there's no limitation to a single manufacturer, just a compilation of heli developments all over the
world.
Let's try with some logic: The Beija-Flor was the first Brazilian Helicopter, the BF-4 (or BF-2 ?)
a derivative of it by the same company. Why should they go back to the number "1" for the next step ?

So, come on, your evidence, please !

My dear Jemiba,

if they wrote on it BF-4,that's mean it was Beija Flor BF-4,and CTA/IPD was concerned
with his developments.

... but we are still speaking about the design called "Abelha-1", as the
thread title says, aren't we ?

(I agree, that it was unwise to start a thread for such a design, will rectify this )

My dear Jemiba,
