CharlesP, not that I would trust. It really is not a hard thing to do to beef up that area except for the covering. century Jet is the least out of the bunch for mods all you have to do is add quality ply to the spar due to cutting some of the spar away to clear the strut. In this case the covering is not really effected. With care you could make full mods to the retracts if you want and keep the covering. It all depends on your experiance.
