I guess I've just never heard of the primary design load for a shear web being the vertical compressive load between the upper and lower spar. Maybe it is for models.

Is this because of things like 3-yr-olds stepping on them? I just don't see it as being a major player during flight, but rather in between flights.....not a condition I would design a plane around.

Heck, I have a big enough engine on my Eagle.....I'll just add so much wood in every direction that it will take an 800-lb gorilla to break it.

I was also amazed at the "quality" of craftmanship in the GP Christen Eagle II ARF. The shear webs didn't even touch the ribs, just were glued to the spars. I don't even know HOW my particular break happened (in flight, storage, transport, etc). All I know is that the more covering and sheeting I peeled back, the more damage I saw.

I'm just very lucky I found it before I flew it.

Thanks for the feedback, guys.
