I have two of the Hobbico Sukhoi. one with a OS 91, and one with a Saito 91. The OS performs very well, plenty of vertical, by far one of my favorite planes. The Satio doesn't get the job done on 3D activity. I have tore the landing gear out by overshooting the run way , but went right back with some 5 min epoxy. Out of the 15 planes this one is right behind my Goldberg Ultimate. My only regret is I bought them when the plane first came out and paid full price.

Was the Goldberg version just to heavy?
