Yeah, my guy will scan and print the canopy for less than $100,000.00 ;-) From: Lancair Mailing List [mailto:lml@lancaironline.net] On Behalf Of Paul Miller

Subject: [LML] Re: Legacy canopy latch setup We have the talent here to do a 3d model and some wind testing without the need to fly someone's airplane or do full power taxi tests. Brunner could even get his guy to 3d print the canopy from all the photos. The canopy is an airfoil, sometimes moving by itself.
Paul I've been following this Legacy canopy discussion mostly out of curiosity. When a good friend dropped in with his Legacy, I had a look at the latches. I took a photo of both the Legacy and 360 latches in the locked position for comparison. Assuming both aircraft were properly constructed and adjusted, I found the 360 latches to have a much more 'positive' engagement with the stricker. By that I mean the latches end with a much steeper and secure angle against the stricker. -see attached. Regarding flying qualities with an open canopy, the 360 has also had greatly varied reports ranging from uncontrollable to non-event. I am curious if PIO played a roll in any of the flights that didn't end well. Also, I like having the ability to pull down on my canopy just prior to latching it. I realize a handle at the top of the canopy frame is not standard, but perhaps it should be. Done right the latching mechanism on the Legacy works very well. That said, it's important to adjust the latches so that both sides are working equally. When setting them up I do one side at a time by disconnecting the linkage at the crossover tube on one side and adjusting the other side. Then reverse the process for the other one. To check it out I put a piece of masking tape on the latch fingers on both sides and close and latch the canopy. If both side are working equally there will be evidence on the tape. It's possible to have it appear that all's well when you latch the canopy but only one latch is doing all the work. It's worth the effort to assure both sides are contributing equally to the latching. With the canopy up and the latch lever lowered the fingers should move down and then slightly back up when fully latched. This assures the overcenter function is correct. By the way, Josh Brungardt told me once that a Legacy will fly fine with the canopy open but the problem is that distracted pilots forget the most important rule: fly the plane, fly the plane, fly the plane!
