Lavochkin La-7 aircraft were the ultimate development in the Lavochkin series of fighters during World War II. Their stopgap predecissory were made almost entirely of wood, and were easy prey to Luftwaffe fighters.

In 1941 development started on upgrading the fighter's airframe to accommodate a 14 cylinder engine, replacing the formerly used V-12. The goal of designing the Lavochkin La-7 was to achieve longer range and higher overall performance.

The resulting Lavochkin La-7 was an excellent thourobred fighter. The aircraft featured the most powerful engines put into Lavochkin fighters, the Shvetsov ASH-82FN that produced 1,850 hp. In addition to greater engine power, the new aircraft used metal wing spars in place of its predecessors wooden ones, was lower in weight, and had drag reducing streamlining. Its pilot was protected with thicker cockpit armor. Advanced models of the aircraft reduced pilot workload by introducing single lever propeller pitch control.

The Lavochkin La-7 was highly maneuverable, with a fast rate of climb and excellent high altitude performance. The aircraft quickly gained a reputation as an excellent fighter. It was extremelly responsive to control and could outperform all other Soviet fighter aircraft. Its three 20 mm cannons delivered a deadly punch

According to some records, Lavochkin La-7 aircraft downed some 3,100 Luftwaffe aircraft vs. only 115 of their own aircraft being lost.  One is credited with a victory over a Me-262 jet fighter, the only Soviet aircraft to do so.

Over 5,750 of the aircraft were produced. These aircraft continued to serve the Soviet Union through the mid-1950's.

Lavochkin La-7(LaGG-3)

The Lavochkin La-7 from a short kit from Red Star RC has a wingspan of 66". Fuselage length is 59". It uses balsa and ply in its construction. You can use from a .90 to a 1.20 engine. Upon completion it should weigh approximately 10 lbs.

We received the following email from Brian D. Brengle:
"On this web page aircraft image number 4 from the top, (the aircraft is marked with the #27 on it's fuselage), is a LaGG-3 and not a Lavochkin La-7. I am an American but I love SovietRussian aircraft. The La-5 and the Yak-7 and 9 are most impressive. I would like to see them in a fight, one on one, against the most modern WWII Allied Aircraft. I do understand that LaGG stands for Lavochkin, Gorbunov, and Gudkov. A LaGG is a Lavochkin."
Thank you Brian. Good catch!

Jeff Mohn wrote to tell us: "ESM has a new Lavochkin La-7 coming out soon. Both YT and KMP will be carrying this plane." Thank you Jeff.
