I have a laser 3D that I got from a friend ready to cover I do not have the Instruction book can all you that have built this model tell me where the C of G should be for a good starting point also Control throws for normal and 3D flight. I have a Laser 70 engine in it at the moment but may change to a lighter engine if I can't get the C of G without adding tail weight.
Thanks in advance.
