Default Remote controlled Tip Up Canopy

Anyone going to try to attempt this with their rv-14?

Hmm, kinda' like air bags on a pinto with a pair of 16" sub woofers in the back...

It's occurred to me, but if they are electric jack screws and one fails, the canopy will have a very bad day.

I'd be more prone to using a shock strut on one side & a jack screw on the other. Shock strut would follow the screw, just like lifting from one side manually.

Ultimately, too cute and not enough justification for the extra weight.

The remote has a mini 2 metal antenna. That seems like a failure prone situation right there. I wonder what the standby current draw is on the receiver in the plane. High coolness factor for sure though.

Tried to engineer this on a Lancair with two jack screws. It could not be done since the two jack screws fell out of synchronization every time they went through a cycle. This, however, could be done with hydraulic or pneumatic struts since they would self equalize. Or, two gas shocks and a center jack screw. Then you have the problem of getting stuck inside if you have a failure or an off field landing. Probably not a practical option.

A buddy of mine had something close to that on his non-RV homebuilt. Once he got the plane flying, he removed that system permanently. The possibilities of a non-good event regarding it were higher than he liked.

He kept that plane more than four more decades, and never once reinstalled it.

I'm no engineer but I bet figuring out a way to override it if it did't function would be the hard part of the install. My first thought was wow that is cool Second thought was what happens if it fails?

Unfortunately airplanes don't have the capability of absorbing extra unnecessary weight for something that is not needed for safe flight. The air rams in this case weigh twice as much as the struts we use. Then you have the remote unit, the compressor, the valving and tubing.

It's kinda like having a wristwatch TV with remote control........
