RC Outlaw,think you have the c/g advice backwards. If the plane is nose heavy the plane will be more stable in flight,if to nose heavy the there will not be enough elevator control to fly. Tail heavy, the plane will be more responsive with the control inputs,to tail heavy the plane will be to pitch sensitive to fly.
Dogz, if you'll build the plane by the prints you'll have a great flying plane,if you bash or change the flight design then you'll probably have a dog,either your controls are loose,flexing or not moving enough,you said 130%,you need to see how much they move up and down,use a ruler if thats all you have.If you can't do all the basics and more with the trainer,then moving up three or four planes on the learning scale is something you will not enjoy. check out; www.geistware.com
