There was interesting episode in the book written by Alexandr Pokryshkin about the test fights between P-39 vs LaGG-3 and Spitfire vs LaGG-3.
Pokryshkin and the pilot from the neighbour squard Sapozhnikov (his squad was re-equiped with Spitfires) were asked to fly to Tbilissi and participate in the test fights against new version of LaGG-3 (lighten version with M-105PF engine) which was put into production in Tbilissi aircraft factory.
Pokryshkin flew P39 and Sapozhnikov flew Spitfire. They should have to fight with test pilots from LaGG-3 aircraft factory. According to the rulez of competition LaGG-3 started fight sitting on the tail of it's opponent. Though it was quite unfair Pokryshkin had to accept this.
Hi put his P-39 into a sharp turn watchig LaGG-3 closing the distance, and then suddenly Pokryshkin made a barrel roll with alt decreasing, forcing LaGG-3 to overshoot. Few seconds later Pokryshkin catched LaGG-3 in the gunsight. It was not difficult for him to sit on LaGG's tail for the next few minutes.
Later on he put P-39 into the vertical climb and made a reverse turn on top. LaGG's pilot tried to follow but he was not that skilled and had to finish climb below P-39. Pokryshkin, again easily put LaGG into the gunsight.
As for Spitfire vs LaGG-3, Sapozhnikov also managed to win turnfight in Spitfire vs LaGG but during vertical fights LaGG and Spit seemed to be pretty even.
Then the diving test was performed. Three planes: P39, Spitfire and LaGG-3 were put into deep dive simulteneously and while P-39 and LaGG dived wing to wing, Spitfire was far behind. The following zoom climb gave even more advantage to P-39 and LaGG over Spitfire.
Overall the chief engineer of Lagg's factory was quite dissapointed with the results. Pokryshin said him after the end of trials not be so upset because the new LaGG was not a bad plane, and the results depended mostly on pilot's experience and skills.
