Thorp Air Command - T18.net

Has anyone used or given consideration to this slick little fuel vent?

My main concern has to do with it not extending down far enough. Thanks.

Yes - I would hope that the ram-air effect is sufficient. It would probably be in the relatively smooth boundary layer. It is a nice looking piece, but a lot of money compared to a simple piece of 3/8" tubing. It's possible that it could work even better - it would be interesting to see a test. Having a full gravity feed system, the ram-air effect is particularily important to me.

My 45 degree cut off 3/8" tube sticks down about 1/4" on the front side. Works fine. My concern with this vent is how it might complicate removal of the floor.

You mean something like this ? Got it from http://www.aircraft extras .com . I do not have a gravity system but this little gizmo has been on for over 200 hours with no problems . Not sure if Aircraft Extras still makes them/sells it . They may have some old stock . I think I paid $20.00 for 2 + shipping . Looks good and stays out of the way . The aero engineers can jump in here , but I don't think it takes much positive pressure to "pump up the tank ?" Sorry it is a little "fuzzy" but I think you get the idea .

Thanks John, Bob and Rich! Didn't think about floor removal but good to know this type of vent is working without issue for at least one Thorp.

Do they come with the sharp shades?......Dan
