Thanks for the input thus far. I am well aware of the purpose of shear webbing and how it should be installed. my intention was to see if other TF GS P51 owners might take a peek at their models (if possible) and verify the direction of the grain. When I cut mine apart, there was one webb near the retract that was correctly installed. All of the webbing on the backside of the spars were put in with the grain running parallel with the spars.
Thanks for all your help!
If I am on to something, it could prevent more accidents......
