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

 

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.

 

Maneuverability: It can easily turn inside the Hurricane.

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.
