we have an XL1 that has been stored for some time. when i pulled it out of the bag i noticed the grips on the top and side were sticky, like the rubber is disintegrating. i have left it out for a week and it still is sticky and leaving black marks. i have no idea what caused this or how to stop it. any ideas?
It may be the compound that the grips are made from. I know from some of the materials on helicopters that salt air moisture can cause this type of material degredation. Some rubber and plastic compounds have an affinity to moisture and is a slty moist environment, they will absorb this moisture which can result in the condition you describe. Just my guess.
