RE: Spark F3A, from Krill Models - SPAIN TEAM
after 40 flights I can say to youm it is very effective for the snaps and of a big stability in the consecutive inverse roll. Perhaps, be able to be a rapid plane, but it is possible to control and to reduce the speed endured very well being very stable his line of flight. Anyhow, as any new design, the pilot must adapt to everything positive and negative every design. In general, it is a question of a balanced design.
