I have a glass windshield in my F model too.

My K model had a left side glass windshield installed at the factory in ‘74. My right side plexiglass windshield cracked at altitude a few years ago and it was difficult to find a new one because MHI was in the process of switching to stretched acrylic. I elected to change out both side windows to stretched acrylic and got a field approval for heated glass on the right side windshield as well so now I’ve got left and right heated glass similar to the P and Solitaire models but without “High Heat” although I’ve not seen the Low Heat have trouble keeping up with icing.

Interesting. I was thinking the plastic windshield would be ‘cheaper’ to operate.

It may be, not sure. The glass seems to last longer but costs more to replace. But the new stretched acrylic windshields are pretty pricey (2-3x the old). Glass has slightly more visual aberration than acrylic due to the wire mesh, but if you fly in a place that has icing, while the alcohol slush windshield certainly works, glass-electric seems far superior and is certainly the mode of ice protection utilized in most other turboprops and turbofans. I had a catastrophic failure from one corner to the other at altitude due to hidden weakness that was not caught despite the mandated inspection only a couple days prior (I was flying home after inspection)...that worried me and I haven’t heard of that happening to glass windshields (I’m sure it can, but just haven’t seen a spontaneous full-width glass failure with decompression in the absence of any impact). That, along with the fact that acrylic was not available for many months prompted me to select glass. I’ve heard of some MU-2 pilots who (when their glass windshield needed replacement) elected to go back to acrylic and alcohol.

I was able to confirm that a short body M model will fit in a hangar with 20' 10'' T dimensions. Here is the picture for proof. I do have the hard static wick on the fuel tanks as well. There is under 1'' clearance on the hard static wick.

My exact T box end demotions were 20' 10'' But that was to the door not to where the door grate starts. So I suspect you could get really close to fitting in an airplane with anything over 20'' from the fuel tank to the raydome
