I did the same, and the RV-10 vent works great on the right hand side in this location. The only scary thing is cutting/trimming the side skin, donít want to mess that up!

Each vent is ~ 2 1/2 x 1 1/2 inches, plus the perimeter mount. I mounted one on the right side of the fuselage, as high as I could under the top longeron and a few inches aft of the structure under the roll bar. It seems to supply adequate air to the backseater, and doesn't blow in their face, which helps avoid breaking intercom squelch when you have inexperienced passengers.

Very simple to install, very light weight, and I gave the spare to a neighbor for one of his planes.

Default + 3 for RV10 vent

Like Charlie, I put the RV10 vent in for the rear seater in my RV4. Worked great for 11 years and 700 hours. Will do it again for my new project. Ron

I want to use two of these Vetterman air vents for my back seat do they really work on both sides?

Thanks for any real world experience with this.
