Went to Lowes and got larger bolts. [>:] When the Magic Extra first came out there was a thread on RCU about the factory c.g being wrong some said that they had done the math? and that the c.g was wrong and that the c.g should be back about 5!QUOT! or so. Even after reading that I set my c.g by the factory. This met adding a lot of nose weight. When I first flew my magic extra I was very disappointed. There was a huge amount of adverse yaw and the rolls are way too barrel-like. In the last two years I have slowly been removing lead. Slowly the adverse yaw has disappeared. I use no mixing on my computer radio-don't need it. At the factory setting the plane flew bad, even the landings were hard. Take your time, remove lead a little at at time. This will take time but the Magic extra 300l is worth it. If yours is anything like mine when you get back to about 4 7/8!QUOT! it will fly more like a dream. I must be honest, after two years I'm still moving the c.g back a little every couple of weeks or so. The more the c.g moves back, the more this plane is capable of. I love the adventure, out of seven planes this one goes to the Field every week. Good luck, remember to have F>U>N[8D]
