Hi Mike,
The problem I found with the wing was the direction of the grain of the shear webbing, not its quality or size. The job of the shear webbing is to keep the two spars from deflecting in toward each other while under load. The farther the two spars are apart the stronger the wing will be. I did not beef mine up rather I removed the old webbing and replaced it with the same size web with the grain running perpendicular to the spars. Covering will not help here. The manufacturer is probably doing this to cut costs. I cant agree more with you about keeping the airframes light, it is my opinion that airplanes should made to fly not to survive a crash. However the airframe should not be failing due to aerodynamic loading no matter how hard you are flying the plane, this is a
safety issue. The way I see it all of the extra weight I added to the airframe, mostly just much needed CA and a small amount of carbon fiber, does not equal the weight of the the goofy looking pilot I removed from the plane, therefore I am lighter than stock.

I cant wait to get it out and fly it!
