It's worked very well (so far) in that position on our new RV-3....well, it is probably about 3 or 4 inches aft of where you have it, but the coils have worked well.

Default Easy solution

Hi Bret,

Thanks for buying the vents!!!! They are great looking and provide an alternate source of air as you noted.

After you have set up your wing root fairing, remove and rivet a plate to the lip of the wing at the location you want the fairing. Drill the hole in the plate.(About mid way between the edge of the wing and the fuselage side.) Reinstall your wing root fairing fastening the bottom only. Mark the hole location. Remove the fairing and drill the hole. Fit a shim between the plate and the fairing. (The thickness of the bottom wing skin) Test fit everything. Remove the vent and fairing until final assembly.

When you are done putting the plane together before flight, mount the fairing on the bottom first and install the vent accessing from the top. After getting the vent mounted complete the fastening of the fairing on the top of the wing.

Super clean install without the complication of bending the vent tubing in the fuselage.

Hey Thanks for the vents and they are very nice. Thanks for the instructions, that all makes sense now.

Default Inverted?

Bret, my thanks for the vent purchase also.

I'm planning on using the coils and vents similar to yours. But I'm doing inverted fuel/oil. My question is, is there any suction issues do to the low pressure while doing negative G's?

It looks from most of the photos that this vent is at the inboard end of the tank.

Seems like it'll work as well if it were at the outboard end, and you'd save the weight of the vent tube that runs inside the tank from root to tip. It would be out of the slip stream for slightly less drag, too.

Or am I missing something?

--- Oh, never mind. In the wing-low parked attitude, all the fuel could drain out.

Thanks,
Dave

I hope you don't mine me posting the quality of these vents, you can see from the photos the alternate vent path incase of blockage. Not there on the build yet, but does the Vans vent system allow for ram air fuel ventilation? These JDair vents are So cool!

Of course we don't mind at all! They are a very nice touch, fun to make also.

Thanks.
