Mike,

 Ribs are plenty stiff; I think the spars are twisting some, but I know that the hub is twisting as well. Shouldn't be anymore than the normal amount, though, since my hubs (Hunt design) are in the 100-120 mg range and do not have adjustment screws (can't afford them or anything else right now--I haven't bought indoor supplies in 18 months or more)

At our last contest, Hope's model still had a little climb left when it bumped a wall, pitched to about 10 degrees nose down, and held that straight to the floor as the blades tucked backwards and spun at about 120 rpm, preventing the model from pitching back into climb attitude. This from a model that in higher torque settings had made repeated recoveries off a basketball net during the same flight.
