Dave,

The aileron roll was just too tame for me, but to be honest, I never "measured" the actual throw, just left it at 100% ATV (AFR for Futaba). With that said too, I'm sure there's 20-22mm, but I'll be measuring everything before the next outing. Light weight tube? IDK, the one I have is aluminum and feels pretty light.

SPT10? It may never want to land!
