Over all quality is excellent. Cable pull/spring return for the rudder and elevator are light and effective but intended for soaring not aerobatics. assembly instructions are sparse, and ESC programming was not covered, but worked for me. Fully assembled weight with radio and battery was 723 g (25.5 oz). The two month lead time for delivery was not enjoyed; Especially since I paid extra for fast delivery. It looks like USPS was the problem.
