🙂 Thank you all…I’m ordering it.
As soon as I’ll finish my Chilton model, I’ll continue with the Gull.

Can anyone help me to locate some accurate 3 view drawings of the Gull 6? I need drawings with fuse and wheel spat sections etc. Any help would be much appreciated as I am having a model of Jean Battens Gull made….

There is a book they claim to have some 3 views inside. I would buy one, but I have no idea how the 3 views look like.

Does someone have the book? Could by please let me know your opinion? Thank you..

…..and three and a half years later, still I haven’t found it! But what I have found is an extract from ‘The Aeroplane’ of 16 August 1939, page 232 of which reports on the annual show of the Eastbourne Flying Club and mentions that: ‘The display began with copious demonstrations. Mr. A. Munro flew the Tipsy well, but remotely, and was followed by Mr. Pickard in the Czech Bibi 556, which also has the 60 h.p. Mikron motor’. Maybe that is where I saw the photograph? If so, I don’t have a copy of that issue. Does anyone out there have it?

try to look here:

The pics quality is rather poor but yes there is the Bibi on the 2nd page.

A local newspaper info:

Czech plane crashed on test flight

Shottesbrooke accident

THE Czechoslovakian two-seater plane which crashed near Shottesbrooke Church on October 25, was on its test flight for the renewal of a certificate of airworthiness, it was stated at an inquest at Windsor on Thursday last week.
A jury returned a verdict that Michael Chorlton, the 37-year-old film director pilot, and his passenger, Tom Manley, aged 24, died by misadventure.
Ten days before the accident the plane made a forced landing at White Waltham when the engine cut out because of fuel starvation, it was said.
Mr. Frederick Clifton, senior investigating officer for the Ministry of Civil Aviation found that the sealing washer on the fuel filter was displaced. If this had happened in flight the petrol pumps would have failed, he said. One of the witnesses of the accident, Mr. Albert Bye, a cowman, of Butcherslane, Shottesbrooke, thought the little blue plane he had seen overhead was a glider. Then there was a whistling sound and, it began to spin towards the ground, eventually crashing a few yards from him behind some trees.

I think, most of the factory plans do still exist, but it would be necessary
to recalculate the entire airplane according to the current rules. It would take
a long time to do this. The czech CAA is very strict(is called somethink like
“Aviation Subduing Authority” among pilots), so it would be necessary to
build the replica in some other country.
There are several more problems – e.g. I do not know if there exists a suitable
engine.

Flying capabilities of the machine – flying the positive maneuvers could be really nice.
Vertical maneuvers would be probably limited by a high drag.
By the inverted maneuvers it probably never could beat planes with symetrical airfoil like Zlin Z-50, Extra 300, SU-26…
If I compare the mass/power ratio:
-720kg/221kW = 3.25 (Z-50)
– 920kg/295kW = 3.1 (Su-31)
-1080kg/317kw = 3.4 (Ba-122)
– 830kg/95kW = 8.7 (Tiger Moth)

Please note, the airplane has been designed more than 70 years ago. In that time it was probably one of the best aerobatic designs in the world. Since that time many things changed.
If I consider the effort to build a single piece of this airplane fully airworthy
and the maitenance/flying costs, I do not believe somebody is gonna build it again…

Hallo, if your friend needs better resolution pictures,
drawings etc. just let me know…

Pilot Novak, Siroky, Hubacek & Avia Ba-122

Here are some pictures scanned from my archive.
Those are photos of great men who flew this wonderfull
machines many years ago, photos of fabulous Frantisek Novak’s
aerobatic team.

“The outstanding aerobatic pilot Frantisek Novak,
flew OK-AVE to 4th place. Vincennes Rally, June 1934.
Also Novak, encouraged by the B. 122 designer, formed a top line
aerobatic team. Novak, Siroky and Hubacek taking out 2nd and 3rd ,
1936 Berlin Olympic’s contest.
Top 3 for there class Zurich meeting July 1937.” (see Stormbird’s note above)

The pictures below were mostly taken at Plzen(Pilsen), May 10th 1936
at old Plzen-Bory airfield (1911-cca 1960, a university has been build there later).
I personaly met the Mr. Hubacek many times, I was a joung
boy at the moment.
He was really a gentle and modest man, friend of my grandfather.
Several years later, after he died, I have found he was “the famous Hubacek”…
