At about 250 hrs air time, my 2008 RV7 developed cracks in the gel coat on the wing tips. I have been learning aerobatics and max G to date is +4/ 0-
The cracks run fore/aft parallel with direction of flight and the outboard edge of the tips, and inboard about 2 inches from the outboard edge of the wingtips.
On close inspection, the wingtips appear to have been laid up using a single piece of woven fiberglass cloth, except at the very outboard edge of the wingtips, where there are at least 2 additional layers of cloth. My cracks have developed beside the inboard edge of the 2 addtional layers of cloth where there is only 1 layer of cloth.
Are these cracks common?
How deep/wide should I excavate the cracks in preparation for filling with fiberglass resin and "bubbles"?
