Here's a quick cut at a smaller version of your FF-2 design, built around the 12Y engine (using the Klimov VK-105PF derivative as a model):

A fighter designed around the Hispano-Suiza 12Y-90 engine (a development of the 12Y-51 for more power and better altitude performance). Equipped with 2 7.65mm machineguns in the nose and 2 HS.404 20mm cannon in the outer wings, and a bomb rack capable of up to 250 kg of ordnance under the fuselage. Fitted with 8mm cockpit armor and self-sealing fuel tanks.

And here's an alternate version, using a different armament of 4 11mm Madsen MGs (Peru uses the Madsen LMG for it's Army LMG, Madsen is a AEGIS country company, and the 11mm is light and small) and a 20mm motor-cannon.

And here's a later version, built around the Hispano 12Z-19. The weight is starting to spiral upwards, so I went with the lighter armament of 4 11.35mm Madsens and 1 20mm HS.404 motor cannon, going with 2 HS.404s and a pair of Madsens needs at least another 300 pounds.
