Sceadu Evo 30 main blades

[twopart]

Has anyone ever experienced the plastic coating on main wooden sceadu evo 30 rotor blades having air pockets appear under the plastic coating near the root of the blade ?.
I keep my Sceadu stored in my water tight and dry shed and have had air pockets appear.
Is it still safe to use the blades when they are like this or should they be changed ?.
The blades are 6 months old and have used a gallon of fuel flying time.

Has it got hot in the shed?, as it might just be expansion of any air that was trapped under the covering when it was put on. If it only looks like the covering has bubbled then I don't see it being a problem. Check to make sure they are not warpped or mishappen, or that there is any undue flex or irregularitys in the blade (small cracks etc). But if you are in any doubt, bin them and replace them.

Running a hair dryer over them will shrink the covering down a tad & get rid of the bubbles
