Juan-----This was discussed in detail in earlier threads on this list and I hate to rehash it again. But, I will answer your question.
The ROLL- OVER protection comes from the structural cage built to support the gull wing doors, fixed windshield and the added ROLL-OVER bar.------------- Yes, the gull-wing doors might be impossible to open when inverted, but so would the bubble canopy. That is why, there was quite a bit of discussion on this list about having a "break-out" knife in the cockpit at all times, similar to the ones in the old F-100 airplane (USAF). Your chances of being conscious after a roll over are much better with the roll-over protection and therefore you are more apt to be able to use the "break-out " knife to exit the airplane. � (just my opinion)
Larry--I have no objection to someone departing from the plans----- I think it is great. I had visited the site on the "no slat" system and your site. I commend you on your accomplishments. I commend you on the way you registered your airplane----- you did not call it a CH-701.
To me, I think the person that is increasing the 701 by 10 percent ( he has everything approved by Chris H. is going to have one of the most practical (701 ?) around. I think you are misinterpreting what I am saying. That is: do what you want, enter the realm of experimental, BUT, call a spade a spade, if you make major changes that change the flight characteristics to the airframe do not call it a 701. I.E. if you buy the plans for a 701 (Zenith has their money), build the airplane with MAJOR changes you have done nothing wrong as long as you don't call it a CH 701 or do anything to market "your design". I feel the agreement with Zenith is: one set of plans means you build one airplane.
I also agree that there are areas in which the 701 can be improved. But, without slats ( they preform a specic funtion to the airflow, which votec generatons CANNOT duplicate) it is going to extemely easy to enter (very quickly) a higher angle of attack than the modified wing can handle thus producing a unexpected stall.

Big,
How do you get roll over protection from gul wing doors?� I respect your perspective on the bubble canopy, but I am trying to understand the gull wing theory. How do they help in a roll over?
