YAK-11 Shevtsov Ash-21
Hi all, am hoping you can help out. I have been asked by a friend to see if
I can lay my hands on or get as much tech info about the Shevtsov Ash-21
engine..
Basically he and a friend have managed to get hold of an engine, and want to
re-build it. So if there are any manuals available, where would be a good
place to start.
TIA
Simon
