Yak-3 wheel door:
I have always admired how the russians have made these things simply and still workable.
Is that a tennis ball just behind the cockpit?? What the....
And the tail wheel retraction system was also cable actuated. Effectively everything was driven by electric motors mounted on the wing spars. Tank and his fellow Focke-Wulf designers considered this to be less vulnerable to damage than a hydraulic system.

The Ta 152 had a Junkers VS 9 propeller witch had hydraulic operated pitch adjustment, so a hydraulic system was needed anyway. The BMW 801 had the electric pitch VDM propeller and AFAIK there was no hydraulic pump on board at all. This could be the reason of the change.So why did they change to hydraulics with the Ta 152?

Ok, just imagine that a hydraulically operated pitch adjustment is more complicated than an electrical one, is it?
Hydromatic props are usually self contained, separate from the main hydraulic system, I would imagine the 152 was configured this wayThe Ta 152 had a Junkers VS 9 propeller witch had hydraulic operated pitch adjustment, so a hydraulic system was needed anyway.

there are no inner doors at the Me109, only outer doors at some late K versions. I think you are talking about the Fw190.
