Steve, No you are not mistaken. The amount of spanwise acceleration on a wing panel is nil for most any maneuver we fly, excepting a snap or extremely fast regular roll. Maneuvers such as blenders can place considerable outward acceleration on a wing but only at the moment the model transitions from the fast roll to the inverted spin.

Having said that, I have heard pops come from models that had wings secured with rubber bands, as the wings separated a little and were slammed back against the fuz. Point is rubber bands stretch... Duh!! In a pattern model where extreme maneuvers are practically never done, rubber bands work fine.

I am working on a method where the wings will lock automatically when inserted, similar to a door latch, because I am inherently lazy about fishing the acorn nuts I use to secure the panels. Also, nothing to lose
