Default Stall vane protector

I wonder if I?m the only one with this problem. I have a love/hate relationship with my stall warning vane. I love it when it beeps as I touch down. But I hate it when it tears up my good pants, leaves a scratch, or worse still leaves me wondering if this time I?ve finally wrecked it.
I share a hangar with 3 other aircraft, and it?s tight. When my 12 is at the back, the Esqual tail feathers leave me about a foot clearance. When I get focused on a task, I forget, and ?ouch? again.
Larry recommends putting a small radius on the corners. Is that really enough?
This is one little challenge that has me beat. Has anyone out there come up with a practical stall vane cap that protects you both?
Help needed
Rod

Larry sez; Radius the corners 1/8" and you won't tear up your pants any more.

Take a yogurt cup, cut a big round notch in it to match the leading edge curvature, and hold it on with a piece of blue painter tape.

The slight radius of the corners worked for me.

Default Raquetball?

How about a racquetball - they're hollow rubber, about 2" in diameter. Cut a slit in it and slide it over the vane. They're usually blue in color, but I think you can get 'em in "remove before flight" red, too.

How about remembering its location and not walking into it?

At my age just remembering where the wing is makes for a trying day.

We use a wine cork with a slot cut into it and red tape to hold it together and then hung a red remove before flight flag on the end. The price will vary depending on taste.

A stall vane that is painted a bright yellow is easier to see and avoid.
A homemade AOA probe does not protrude beyond the wing leading edge. See http://www.vansairforce.com/communit...7&postcount=14
An AOA will give a progressive warning, unlike the stall vane that is either on or off.
Another option is a Cessna reed type stall warning system that is flush with the wing.

Although it might not be loud enough to be heard in a noisy cockpit.

After seeing this thread about a stall vane protector I became obsessed with coming up with a solution. I came up with the following design.



I put the instructions on my build page
