Soviet pilots were generally satisfied with the La-5. "That was an excellent fighter with two cannons and a powerful air-cooled engine", recalled pilot Viktor M. Sinaisky. "The first La-5s from the Tbilisi factory were slightly inferior, while the last ones from the Gorki plant, which came to us from Ivanovo, were perfect. At first we received regular La-5s, but then we got new ones containing the ASh-82FN engine with direct injection of fuel into the cylinders. It was perfected and had better maneuverability, acceleration, speed and climb rate compared to the early variants. Everyone was in love with the La-5. It was easy to maintain, too."
