150cc
Not doubting the convenience factor on this... but I am also not super impressed by how rigid the stabs can be on the removable stabs for small planes. I dont think the convenience is worth the price and weight of the extra required servo on smaller planes. On the bigger 50cc + planes it makes more sense because you need two elevator servos anyway.
My 30cc plane has two tail servos and weighs 10lbs 6oz. Also they could design I so they work as one unit and work with one servo. Rigid stabs? You say they need to flex?
