Brewster v. Hurricane   http://www.warbirdforum.com/eagle.htm

 

The following information comes from the RAE Farnborough test in September 1940

 

Field of view: The view to the rear is far superior to the Spitfire or the Hurricane.

 

Climb and Dive: The climb to 15,000 ft. is better than that of the Hurricane, and the aircraft easily out-dives the Hurricane.

 

Turning : It can easily turn inside the Hurricane.

Rolling: The Buffalo easily out rolled the Spitfire, especially at higher speeds.

     At 390 mph. IAS the Buffalo could bank 45 degrees in 1.6 seconds using

     24 lbs. of stick force. The Spitfire took 3.5 seconds using 80 lbs. of force.

Ailerons: In the speed range of 90 to 400 mph. IAS the ailerons were exceptionally

effective, crisp and powerful, superior to the Hurricane or Spitfire.

 

 

The aircraft flew itself off without assistance after a shorter take-off run than

either the Hurricane or Spitfire. When airborne it accelerated rapidly and had

a good initial rate of climb. The landing was easy. The approach glide was steep

allowing an excellent view of the aerdrome. The aircraft settled down after a small

float with no bounce or swing. Once on the ground the Buffalo was very maneuverable

and could be turned in its own space.

 

Stall speeds: 76 mph. IAS with flaps and undercarriage up.

                      64 mph. IAS with flaps and undercarriage down.

Finnish Brewster B-239's were export versions of F2A-1 with  Wright_R-1820-G5 700 kW (940 hv) engines. With these FAF eventually shoot down planes like Yak-1 and La-5 ... iirc the most air victory claims in a FAF Brewster was 36 (for plane).

 

F2A-3 might have been screwed by added equipment.

 

The RAF and the Dutch did ok with their F2A-2's against japanese (if looking at exchange rate, cynical view I know).

 

Finnish pilot thoughts about Hurricane was that it was sluggish and unresponsive but stable platform for shooting.

That is pretty much how the Russian pilots thought. Nikolay Gorlodnikov preferred the I-16 type 28 to any Hurricane.

BW-371 LeLlv36 arrived to Finland 21.3.1940, destroyed in Suulajärvi 22.2.1944 total flight time 413.30 hrs. One of the 3 Brewsters refitted with Shvetsov M-63 engine and AW-2 propeller. BW-371 was also refitted with VL-designed metal wing, ment to VL Humu. Probably this picture above is from those times in VL factory in Tampere.

Did not find reference for this being "Vikki" Pyötsiä's plane, he flew at least BW-376.
