Perhaps it is because of the model's mass, but I did not have to apply much rudder at all to keep it on track and the loop vertical. Of course, there was almost no wind. Combining rolls and loops is what aerobatics are all about, and the Staudacher handles everything effortlessly. Having that smoke tracer behind you is a big help when you try to keep things lined up. That long, flat-sided fuselage really helps extend the maneuver.
Inverted flight is also effortless, and some forward stick is required.
Spins do require that you fully stall the model before cranking in full rudder and aileron. If you enter with too much airspeed, the spin quickly becomes a spiral dive. Inverted spins are also easily accomplished. Some opposite rudder should speed recovery time. Powered by the 3W-60 engine, it is truly an unlimited aerobatic performer.
