I've been following this debate since I started building my -6 nearly 20 years ago. In all that time, this is probably the first time I've heard someone make the case that visibility is better in a slider!

Sam- pass the popcorn.

Probably. Doing so might make your eventual egress easier... or it might prevent you from egressing at all if you are knocked unconscious because you sacrificed the protection afforded by a closed canopy. Water can be awfully hard. Chose your poison, but think it through ahead of time and chose carefully.

Pointing out the YouTube video was not to suggest favoring one canopy over the other. It was a response to the comment that the slider canopy cannot be opened in flight.

it was an emergency landing after a collision , engine shut down .... the pilot managed the emergency landing very good opening the canopy before touch down but when the plane hit the water and inverted the canopy slide forward and close again so it was impossible for him to vacate the plane , it was only with the help of some people in the beach nearby that his was rescued .....so install a device to block the canopy in the open position otherwise when it happen to invert it behaves like a tip up

Dave,
As a Southern Jurassic RV4 and current RV6X Slider owner, canopy type boils down to one thing, comfort.
Having flown a very well air conditioned Jet with a forward tilt-Up (F-16C) for 25 years, I appreciate how hot it gets in an RV on the ground or in the air in the summertime. Visibility is another thing, no canopy bow=better visibility, no argument there. The F-16 and tilt-up RV share that distinction and it is nice.
However comma, for me comfort wins. Taxiing the 6X on the ground with my arm on the rail is well, nice. My RV4 canopy was high enough to allow the same.

As far as jettison goes, my Four had a pin that held the canopy open well above the rail and I cut slots in my rail on the RV6X Slider so it can be removed/jettisoned if need be. The RV4 plans say it will "tear away" if slightly opened inflight as several owners inadvertently discovered. In the F-16 any landing gear EP included optional Canopy Jettison. That said, I have slowed my 6X down enough to slide the canopy aft inflight. High AOA is the key, the higher the Alpha, the easier it is to slide open and potentially jettison.

I 've witnessed two RV nose dragger flip-overs right in front of me, both from botched/buffooned landings turned PIO, nose-first touchdown, broken off nose gear. No anti splat device would have helped and both individuals would have been trapped a long time without help. Both, very avoidable.
The other scenario is a engine failure/forced landing off-airport in questionable terrain. My personal technique is I carry a Smith&Wesson 9/11 tool (glass breaker/cutter)https://www.amazon.com/Wesson-Respon.../dp/B009XN12UM I plan on canopy jettison if time/altitude permit.

Hey Smokey, knife looks nice. Any idea if that's made in the good old USA?

Of note the tip up on the 12 and 14 is very well engineered with much more pre-fabricated as compared to the 6 and 7. I felt the 12 as a tip up was much easier than the slider 9s and 7s I built so I assume the 14 is the same too.

With that said by my observations and help on a friends tip up 9, I think the slider is easier for the 6,7,9 models. It is much easier to adjust to fit with fiberglass covering up an miss-alignments at the windshield junctions and in my case by fabrication a carbon fiber reinforced rear skirt. I probably spent 100 hours on my recent slider and I suspect my friend invested over 300 hours on his tip up.

Panel access is now a non-event with a well designed assembly with the big holes for two glass panels. Remove the displays and you have direct access.

If you put the flaps down and slow the plane down, you can probably open the slider in flight.

The real question is, can you get it open in level flight, at speed?

Anyone willing to try (with a safety chute)? Also, is there any info about being able to open either a slider or tip-up during a spin if one ever needed to bail with a chute in flight?

I think this has been discussed here on VAF at length, and the answer is yes, the slider can be opened in flight and there is at least two document cases and one with an egress... speed is unclear.

There may be others.
