Prikladam data, ktore sa mi podarilo krvopotne pozbierat z dostupnych publikacii a mojej sukromnej zbierky o Avii.
Zaroven poprosim nekopirovat textury kokpitu (ovladaci panel, budiky, atd.), ktore sme pripravili exkluzivne pre IL-2. Mozu posluzit ako predloha - referencia, ale nie ako priamy copy/paste material. Nedavam na to suhlas. Dakujem, za respektovanie nasich autorskych prav.
Bohuzial, uz sa to raz stalo pri mode do OF. Preto ten negativny postoj z mojej strany.

in 1935 Avia’s could be easily recovered from either left or right spin
by itself without even pilot touching the controls after about 2-3
