According to Jakowlew only LaGG-3 was made of Delta wood, due the loss of Phenol fabrics in 1941, they take "ordinary" wood to produce these fighters. Making planes Ohter fighters like Jak-1 were made of "ordinary" wood it seems. Wood has one advantage in the production, that was a also a disadvantage. If it was less carefully built, it could do the job at the airplane, but caused also much perfomance loss. Especially Il-2s in 1942 suffered from this problem.
