Default Bug screen

I have plastic scrub pads inside my scat tube, still get good flow but no bugs. Good choice for something simple

Default A bit different animal

While the suggestions are great - and similar to what I did on my RV-10, the 14 is a bit different in that no SCAT tube or room is provided. I (hopefully) have a screen shot showing the build section. The entrance to the vent actually sits recessed in the SV-10 transition duct. I also included a close up view looking into the NACA opening from the fuselage exterior. You can see how close the vent entrance is to the NACA opening.

The only other option I have thought about is to machine or 3D print an insert for the output side of the vent face - that will be visible from pilot & passenger all the time and affix a screen in that area. Not sure if I like that thought yet..

Thanks all for the responses.

FWIW I had no screens for the vents in my -8A and in ten years of flying and many weeks of being parked outside never had a bug come in thru the vents. So I don't plan to put any screen in the vents for my -14 either.

It would only take one time doing the bee-dance to make one rethink this :

I use aluminum honeycomb "kill-flash" material off of ebay. Rough cut on the bandsaw to the ID of the vent plus a smidge. Press into the vent barrel and secure with a bit of RTV, or not. Minimal flow restriction and looks cool.

That may be the ticket I need. I had seen the scope covers before but not the bare material. I now have the info to order some to try out.

VAF comes through again!

Thanks,

There sure are a lot of different types of that material out there. Any guidance on specs?

Default Aluminum Mesh

I used a piece of aluminum window screen, about 3"x3" IIRC. Wrapped it over the NACA outlet, and used the SCEET duct & Breeze clamp to secure the entire assembly. No fuss, No muss, No bees, wasps, etc..

Default Grids

I bought mine from “honeygrids” in the 3/8” thickness. Bought oversize diameter and ground to slight oversize before pressing in the output side of the vent. Added a bit of RTV to keep from shifting. Couldn’t be happier with the results.
The material is like an extruded plastic so has some compressability when you push it in.

What "cell diameter" size did you use? I see they have different sizes from 0.135" to 0.365", and sheet thicknesses from 0.18" to about 2".
