Default 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

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.
