My wife made some nice wing bags for me 10 yrs ago using some old sleeping bags as material. We weren't camping anymore so the bags were recycled into 8 assorted size and style wing bags. Some are open only on one end to slide the wing down into, some open completely up with velcro down the side to close them, and some are 2 piece bags for wings that have wing mounted landing gear. They are all still in use as they have held up well. The thick quilted type material gives good protection to the wings, just clean off the post flight oil residue before sliding the wing in the bag for the trip home or you will have to throw them into the washing machine more often. Use what to got and be creative. I also reuse the clear plastic bags the the ARF wings came in for dust and dirt protection while they are stored in my shop. Keeps them clean and ready for the next flight.
