Talk:Tumansky R-11

Lifetime for the engine
Could someone find out what was the time between two engine overhaul? I have unverified information that MiG-21 was constructed in such way that the engine coul be changed cmpletley in max 4h. That because it was necessary to do that after 20h ao use of the engine. Vacu um (talk) 23:35, 2 February 2008 (UTC)
