Flying with or without wing tie down rings
A quick question to all flying RV-12 drivers. Do you fly with the wing tie down rings attached, or do you always remove them before flying?
What is best practice here?
Thanks a lot
Chris

I remove them. Probably not much chance that they would work loose and fall out but why risk it? Less drag too, although it wouldn't be noticeable. Should add that I don't often use them as my plane is nearly always hangared.

I only tie down on rare occasions, so I install when needed and normally have them in the glove box. So far, in fact, I think I've only used them at Oshkosh. The rest of the time I just chock the nose wheel. I'm generally never parked outside fo the hangar for more than a few hours.

I'm one of the unlucky hangerless owners in SoFla. and tie down. I never remove for flight and do not see airspeed reduction or risk of loss in flight.

Once I forgot to remove them and accidentally flew several hundred miles in my Lancair with them hanging down in the breeze. I didn't notice any difference in performance, but did add "Check tiedown rings removed" to my preflight checklist.

I only remove mine at annual when I install hex head bolts as jack points to jack up one wing at a time for wheel and brake maintenance. I bought a tall hydraulic jack from Nortern Hydraulics and machined a cup on one end of a 2? OD AL bar for the jacking bolt hex head. I bored the other end of the bar to slip over the end of the hydraulic jack shaft. The AL bar is about 4? long. Works great.

Remove the steel rings from the aluminum fittings.
That would be a hint.

Yep, better remove any dissimilar junctions throughout the airplane!
