Canopy Release Handle
 
Is anyone considering moving the canopy release handle behind the panel? If so, do you have a design? Thanks.

If the canopy is the same design as the -6, -7, & -9, then here is one solution:

Simply insert the Tee handle in the bottom and drill it for an AN3 bolt.
I cut off the unused tab off after I was sure it all worked fine.

I wasn't aware any of the other models had a canopy release ( jettison) ?
If you ever need to jettison the canopy I'm assuming it would be an emergency and fumbling under the panel looking for the handle probably would not be good. Or are you thinking like me that you will never have a shute on, so the only point in the release is for on the ground servicing?

I don't know how the -14 is laid out but on the single digit RV's you have to cut slots in the foreskin to let the hinges come out. Then you have to cover the slots with either tape or something to keep the rain out.

Since I don't wear a parachute, I'm not too worried about jettisoning the canopy. Even on a water landing, I will release it and let it slam forward but I want it on the plane.

As for "ground serving", I have done a bunch of panel upgrades and other work over the years and have never removed the canopy. It might as well be bolted in place.

One of the few building tasks that must be done by someone with the moyel endorsement on their repairman's certificate.

In circumspect, I think you're right Paul.

The -14 is different. The 650 will extend into that area where the vertical part of the handle is in your drawing and there is a fuse panel down in the middle. It's almost like it would have to be moved over a few inches, then come down. I'm not sure about the physics and design of that.

Maybe I am missing something here but, has any other RVs had a canopy release and has any one used it successfully to bail out? I suppose that in an acrobatic mode it might be useful. Maybe. It seems to be located on some real valuable panel real estate. It seems kinda nice to have it hooked up with the release handle behind the panel and then the canopy can be removed for maintenance tasks.

Does anyone plan to hide the release handle?

To my knowledge, no one has ever done a canopy release in flight. The original design did not have gas struts to hold the tipper up. My aircraft has the jettison but I've never used it even for ground maintenance. If I tried it in flight, the struts would probably keep the canopy attached to the aircraft, even if I remembered to release the main latch and turn the T-handle.
