3D File for Stall Vane Cover

In case anyone wants this, I corrected the dimensions for a popular online 3D print file for a stall vane cover. This fits perfectly.

Just attach the usual "REMOVE BEFORE FLIGHT" tag to the end.

I can send you the file - just shoot me a message.

Forgive my ignorance, but does the cover provide any function besides increased visibility (once the flag is attached, anyway)?
 
If it fits the RV12, a cover like that would prevent some "doh!" moments.
It took me awhile (and several cuts) to learn to instinctively avoid the stall tab along the port side wing.
And then there's others who don't know any better that might brush in to it.
 
Great question. This helps not only prevent getting sliced open as you walk by, but as a jacket of mine can show you, it would help prevent shredded clothing. Also helps avoid the bend that can happen when you run into it.

To make the tab less likely to cut you, is it OK to slightly round the sharp corners, or will that affect stall warning accuracy?

Not sure I understand it either. Seems like you would be more likely to bang in to it with this extended tab sticking out. Is there a way to make one that would fit flush with the leading edge of the wing and laterally support the vane in case of an inadvertent side load? It shouldn’t have to be that small.

The tab projects from the wing and moves based on the airflow. It is connected to a switch that opens when the critical angle of attack is approached (it is adjustable). Making it flush to the wing would defeat the function. Photo shows what it looks like with the cover and flag attached. For polished wings it is really hard to see the stainless-steel tab sticking out.

Yes, I know what a stall warning vane looks like and how it works. I was referring to the cover you made for it, thinking maybe the cover could be made in a way that would make it less likely to get damaged if someone walked into it……. maybe not.

If one did not mind a much larger cover, it could made to made to conform to the wing leading edge and tapered/rounded on the left and right sides. The thickness at the leading-edge would be sufficient to accommodate the slot for the stall vane tab. The nice part of 3D printing is you could use very little infill to keep the weight light. The current tag cover relies on friction from a tight fit with the stall vane to keep it from falling off.
