Hi,


this was a well known Germany company,the Bäumer Aero GmbH,it built many aircraft and used the series "B",the B VII was a low-wing light transport aircraft project,powered by one 300 hp Wright R-975 J6 Whirlwind-Nine engine.


Also the little know projects,fast single seat aircraft of 1927,light sportplane with a Bristol Lucifer engine of 1928 and a high performance single seater of 1928,but I have only a drawing to B VII.

Re: Baumer Aircraft Projects

Thanks, a very good find hesham.
But a little correction, not baumer...this is wrong...Bäumer is correct.

Have a nice day.
 
Re: Baumer Aircraft Projects

OK my dear Maveric,


I will fix it,but you know that my key board can't write those two points.
 
Just a clue for such problems: You can find principally all characters, when opening
the charmap (start\run\charmap.exe).

Hi,

was there any drawing or picture survivor to Bäumer BV.V Puck,a single seat
acrobatic biplane ?.
 
Another source for Bäumer aircraft is a pdf article of the ADL. It is also in German, so open it in a program that enables selecting and copy some of the text and paste it into Google translator .
