Very nice picture Herakulman. The aircraft is the one and only VL Humu. The Finnish State Factory attempted to develop the Buffalo in 1944. The aircraft frame was metal however the rest of the aircraft was wood. The aircraft was mated with the Russian Shvetsov M-63 engine of the Polikarpov I-16 type 24. Because of its mostly wooden construction it had gained about 550 lbs. The power to weight ratio of the aircraft left it with a maximum speed of less than 270 mph. and maximum climbing ability of just over 2,600 fpm. The armament of 2 x 12.7 mm LKK/42 machine guns was inadiquate and the performance was no where up to 1944 standards so the project was dropped.

Yes,

 

even after they left any armor and some other stuff off, the end result was some 250kg heavier. Also we only received the engine manuals in 1943 and after that they managed to tune the engine right...

 

But it had 3 x 12.7mm LKK/42 in fuselage and that was regarded as better than B-239 (btw, LKK/42 is copy of Colt M2)

Just recently heard that there was one Finnish B239 tested with 1200hp Wright Cyclone engine (probably taken from Curtiss Hawk) and the performance with that was very good, it allegedly climbed in par with Bf109G. There is test report of that in the collection of documents in the museum of aircraft engineering in Jämsä, Halli, Finland.

Now that is a test report I would like to look over. :)

 

     Just letting everyone know that I have come across more performance figures for the B-239.

A special thank you goes out to Michele M. Gaetani for the information. I have edited my post

#3 with the new information. B)

The following information comes from Flying to the Limit by Peter Caygill;

 

Vs. Bf.109E

     Poor performance and inadequate hitting power.

 

Squadron Leader Walter Churchill DSO DFC; The aircraft is not a fighter until the following

     corrections are made;

     1. Firepower needs to be increased. The 2 x 0.5 in. + 2 x 0.3 in. is inadequate.

     2. A reflector gunsight is needed.

     3. Armor protection for the pilot needs to be increased. Present armor is inadequate.

     4. Shoulder straps through the seat do not give proper security to the pilot. The straps

         need to go over the seat.

     5. This aircraft would make an excellent trainer, relatively simple and delightful to aerobatics.

 

R.A.E. comparison to the Hawker Hurricane

     The Buffalo's take-off run was shorter.

     Acceleration and climb was good (comparable) 

     The metal ailerons were exceptionally effective, crisp and powerful. The Buffalo could easily

     turn inside the Hurricane.

     The elevator (and ailerons) were not sensitive like the Spitfire's or sloppy like the Hurricane's.

     The Buffalo could outroll a Spitfire (or Hurricane) using less force at speeds over 200 mph.

     I.A.S.

     The Buffalo's overall maneuverability was excellent.
