    Default Bubble doors

    I am told that I absolutely need the bubble doors to be happy in life. Does anyone have close up pictures of the standard door and bubble doors so I can see if my life will be empty and void if I don’t order bubble doors at some point.

    I depends on how big you and your plane are. If you're normal sized and flying a 1-4 then yes, the bubble doors will significantly improve your comfort. I've attached a picture that might show something informative, though bubble doors are kinda hard to photograph, being clear. Best bet is to find a set on a plane in your area and check it out.

    It looks like it gets you about an extra 3 inches of arm room. What is the cabin width if a 1 - 4?
    Thanks for the picture. It does help.

    Found this cool table that indicates the cabin width is about 39.5" at the shoulders, and about 34" at the seat:

    I absolutely love my bubble doors. I fought with the decision too but took the plunge and never looked back. They do weight more but I think well worth it.

    Ditto. I couldn't agree more.

    I like the idea of having an air rest somewhat with the bubble door. It’s wide enough you can rest your arm on the door cross frame

    I thought I might need an armrest, but you fly with your left hand on the stick and your left arm rests comfortably in your lap, so I have found no need of an armrest on the door.

    That was my thought too, left arm rests on leg.

    So - (WARNING: newbie question coming) having read the above and working on the same question (to bubble or not to bubble) if the cross bar is the limiting factor in shoulder width, and if you will be flying with your left hand on the stick/lap, what is the advantage of the bubble doors?

    Additionally, does it limit the height to which the door will be raised for entry? Does it limit your ability to fly with the doors open? (Or, do you remove them for open door flight.)

    Thanks, Darrel
