I have one with a YS 63. Unlimited power (verticals). They way you get it to 3d is not go by the CG recommendations that is in the manual. Mine is 1 1/2" back from where they specify. Wants a little more speed when landing to keep from stalling. Hovers real good, much better than my Sudokhoi. I believe it is because of the much longer tail moment. Blenders, flat spins, TR, knife edge loops, and pop ups were easy to do. Could not get it to do a waterfall or a harrier, wants to drop off to one side real bad, it is probably me though. Currently fininshing a Seduction Freestyle, it will be at least a pound lighter than the Global copy. The Global plane has been through a lot of abuse, pretty sturdy after you make sure the landing gear plate is reinforced with tri-stock. When I was going through the adding weight to the tail process, it flew better each time, landings were real smooth with a slight nose high attitude. You just don't need all that control surface working. But now it has longer servo arms with a lot of throw. One area that I would try to correct is the differential with those split elevator halves. I used a DB fiberglass pushrod and 4-40 rods to stiffen it up, worked.
