<<<When it folds, the plane ususally noses over onto its  back,>>>

  

 I'm wondering why Zenith doesn't recognize this and  put in "roll over protection?

Bob, Several 601s have nosed over through the years. 

Typically the rudder supports the plane while upside

down.  Mark had a pic on ch-601.org of a plane flipped

in a windstorm being supported by the rudder and there

was a news story recently about a forced lading in a

field that the rudder held up well too.



As for the 701/801, well they have the wings overhead

so that should be adaqaute.



Hope this clarifies things a bit but this statement

might still get another long term debate started.

ONE point of view, I just don't want to risk my  life on that flemsy little rudder.  In their defense there are a lot of  other low wingers that don't have sufficient ROPS, but I don't have to fly one  either without a ROPS.  I'm not even sure if you could get out even if the  rudder should support the plane.  Bob U.

Bob, I share your concern. Its folly to trust yours and your loved one's lives to a couple of rudder hinges that were never intended to be "roll over protection." I am sketching out some (possibly futile) ideas for a 1" 4130 structure that I hope I can attach to structure at the bottom of my project. Slow going so far as I'm not an engineer. That does not take away from the importance. I have witnessed two nose overs in my lifetime. One a Cub and one a sailplane. No injuries because they happened in slow motion. However, an airshow pilot that I respected was killed a few years ago in a nose over because the roll over structure had been remove shortly before the accident. My tractor has a R. O. P.  because its mandated.

I put roll over protection in my HD but it involved  changing the turtle deck. One plus side though was that I did not buy a $1000  canopy but made my own from unbreakable and easily replaceable Lexan for less  than $100.

Do you have some more photos of your canopy that you could post or mail to me off list?

I hate to ask a really dumb question, but ...

 Thanks.

Turtle Deck is not an official aircraft term but it is top area of the fuselage behind the cockpit.



It's called that because it is shaped like the top of a turtle.

Terry, Back in the "Olden Days", circa 1938 or so, the trunk lid of most cars was humped and looked somewhat like a turtle shell.  So the trunk lid became called the "turtle deck" or just "turtle".  The trunk, of course, was just behind the passenger compartment.  It just carried over in aviation to that part of the fuselage that is just behind the passenger compartment, the "turtle deck".

Thanks Jay and others who responded. I hate it when I don't know what 

people are talking about.

I want a canopy like this too. I think Zenith should just post some plans as to how to build an XL with a CH2000 style canopy. Looks nicer too.

The more I think about it the more I think that if I could find someone good at laying up fiberglass it might be a neat idea just to make a aerodynamic top front fuselage that would replace the canopy. It could have gull-wing doors and even some embedded rollover protection.



It's not like the designed canopy is structural. There is a 601 sportster pictured at the zenith site that has nothing but a windscreen.



The fiberglass could even be made removable so you could have a sportster.

Sounds like you want one of the airfox canopy installations from Brazil???
