Disproportionate vibration intensity of the Bf109 engine compared to other planes
Flying Bf109, engine problem leads to serious vibration, making aiming and shooting nearly impossible
(whereas flying Spit Ia, engine problem is hardly noticed).
Testing some Bf109s at the REPKA server...
EDIT: Maybe the Spitfire Ia has the same kind of violent vibrations as well, I do not know, maybe I have not "cooked" a Spit engine until now, you can not do it by overheating the water system (prove me wrong

). The best case I had was "overcooking a Spit engine by flying too long at max throttle, oil temp exceeded the limit and got a "grosvenor failure" message but even then there were no serious vibrations either...
