KR> Canopy hinge
One I was told about by the builder in W Australia.He taxied out with his side mounted canopy int the part latched position to get some airflow thru the cockpit. Forgot about it till he took off, and became aware of it by the extra noise. Tried to close it but the lift generated by the canopy (1/3 total lift I was told)tore it out of his grip and smashed it against the starboard stub wing. Stalled in- I saw the results -broke main spar -extra foam in his seat saved him. Brave soul built anotheris he still around Phil?

KR> Canopy Hinge
I agree with everyone that a forward hinged canopy is safest and a better idea for several other reasons (although a rear-sliding canopy is probably even better). Mine is side-hinged but I've never had any incidents with it. One reason perhaps is I have a printed question on the lip of the panel right in front of my eyes that says "Canopy Locked?" I don't like written check lists so I ignore that question, even though I printed it out and put it there, but just in case I ever do forget to lock the canopy before takeoff I have a neato piece of thin, flexible aluminum than dangles down from the canopy frame, It curves inward on the bottom and has a slot in the center that slides down over a screw on the longeron. I think a lot of KR's probably have the same thing - it wasn't my idea . . . came with the plane. After unlatching the canopy I have to manually pull this piece inward so it will clear the screw so I can raise the canopy. It seems to be a foolproof back-up against taking off with an unlatched canopy. It's very simple and effective.

KR> Canopy hinge
List-Post: krnet@list.krnet.org Date: May 13,2015 Subject: Canopy hinge location Joe; When I was starting to test my Kr-2, stock built with initial canopy mount on the right side, I experienced a mishap which ended up costing me a new canopy and many more hours of work to repair. I was trailering my Kr-2 out to the Eldorado dry lake south of Boulder City Nevada to perform taxi tests and get some experience with the brakes, ground handling, engine/prop performance, etc. While my bird was on the trailer and almost at the dry lake a large truck passed me, I was going about 35 mph, and the wind blew open the canopy and promptly tore it off the aircraft. The plexiglass canopy, of course, broke beyond repair resulting in the cost and time involved to build a replacement. I decided that this was a good safety lesson for me and rebuilt the canopy assembly with the hinge point being on the front edge, the canopy now opens from the rear. I figured that if I ever forgot to properly latch the canopy on takeoff, the slip stream would keep the canopy closed instead of ripping it off and possibly damaging the tail/rudder and causing loss of control. I have had one incident when the canopy latches were not secured prior to takeoff and all that happened was the canopy opened about 1/2 inch in flight, I was quickly able to lock the canopy down without incident while flying the aircraft, the only damage was to my adrenalin gland from the massive amount it put out when the canopy opened that 1/2 inch, it really startled me. The canopy is very easy to remove just by pulling the piano hinge wire out one side and with the latches in the UN position, the canopy can be lifted straight up and off. I do not own a parachute and have never flown my bird while wearing one, my biggest concern about the canopy is how to get out in case of a nose over on the ground but then the location of the hinge wouldn?t cure that problem anyway. Hope this information is useful to those trying to decide where to hinge their canopy.

Paul, There are two other possibilities off the top of my head. I have seen the foreword lifting canopy that basically has 4 attach points and lifts foreword and up as a parallelogram. The other is a foreword sliding canopy. I don't think rear sliding has been done or is practical for KR shape.

I'll give a third option, similar to Mark Jones but with more roll over protection. https://dl.dropboxusercontent.com/u/32133949/IMG_8669.JPG I have a 1 inch thick windshield bow and a one inch thick turtle deck bow.

Is anyone putting with a side hinge in or is everyone hinging from the front?<< Are you going to wear a parachute every time you fly? I doubt it. I couldn't wear a parachute in N891JF if my life depended on it (and I don't think it does). Keep in mind that inflight structural or control failures in these planes are VERY rare. You'd do far better to concentrate on how to get the plane on the ground safely, or at least under control, rather than trying to bail out. Consider that if you take off with one latch disconnected (or even both) the forward hinging canopy will almost close itself...it'll hover maybe an inch over the longeron at the rear, but it will be in equilibrium and stay more or less closed. if you take off with a side hinged canopy unlatched, it will likely slam open, killing lift on the right wing, and stall, if on takeoff. This is basically what happened to Allen Buzza in Australia. Fortunately he survived and went on the rebuild the plane, and is working to finish another. I almost lost the side-hinged canopy on N891JF the first time I started the engine and didn't have it latched. That's when I decided to make it front hinged. Just some food for thought. I could go on, but it's past my bedtime... Mark Langford ML at N56ML.com http://www.n56ml.com

KR> Canopy hinge
Can anybody see any problems with drilling 1/4 holes in the top longerons to secure my canopy hinge? I know 1/4 is a big hole to drill in the longerons but I have been using what we call "T" nuts over here for anything that I can. They are so convenient especially for places like the canopy hinge, where you can never get to the nut again. Problem is I can only get them in 1/4". I'm using 2" open width stainless steel piano hinge for the canopy and the ailerons, I know it's heavier but surely about 1lb in weight is worth saving about $300 AUD for hinges alone. Thanks Gav
KR> Canopy hinge - drilling 1/4 holes
Gavin, I can see your not being able to the to the nut inside the canopy frame, but why can you not get to the nut that is under the longeron. I believe that I have some T nuts as small as #6 and if you mail me off NET, with your address, I will be glad to send you some. And I would have a problem with drilling 1/4" holes in the top of the longeron where it is the weakest as there is no supporting structure over that area. da...@alltel.net "There is a time for building and a time for GOING TO THE GATHERING, and the time for building has long since expired."
