I was out last week practacing landings with my superstar 40. Though I will admit that calling what i do "landing" may be a bit deceiveing but things were just getting better when disaster struck. On take off the wheels had just bearly left the ground when the plane took a hard right and into the fence. Heavy damage to the wing and when i removed it i found the aileron servo was hanging loose. I suspect that is what caused the crash. After reparing the damage and rechecking the cog It also acured to me that the wing maybe should also be balaced but I had not seen any discusion about it. How important is it? Insidently the balance of the wing is o'k even with all that glue, but the fuse is way off. If the plane is assembled it takes about 21 grams at the left wing tip to balance the plane Should i add the weight or is there a better way?
