For any kind of aerobatics, increase the up-going aileron throws to the maximum. Halve the figure for the downgoing aileron. With a rearward CG, the model is quite aerobatic. There isn't really enough rudder authority for confident stall turns in light lift, but the model just about kicks round. Aerobatics in good lift are a lot smoother and enjoyable with a little ballast installed.
Pylon turns are impressive.
It can really whip round on a sixpence without losing much speed. The butterfly brakes are effective. With this scheme, the ailerons go up about 30 degrees, and some down elevator is mixed in to counteract the trim change. With a full load of ballast, the model must be flown faster and wider or you risk flicking. This is a consequence of the laws of aerodynamics, not a shortcoming of the model, but it can be turned to advantage.
