Forgot to mention, If you haven't flown it yet to stick with the above elev throws. I got this from towers site. Also keep some speed when landing- to slow and it will tip stall rather quickly. I really like the way mine flys. My tank(14 oz) is on the cg which is balanced right a four, with saito 91. Ordered a ys 91 fz last friday for it. Good luck...........dave
