RE: CL-415
First and foremost:
Get in contact with a local RC club, and see if someone there can assist you. He will be able to enusure the model is built and rigged correctly, as well as help you learn to fly. If at all possible, assemble an RC trainer kit, such as a Sig Kadet Seniorita before you build the 415. This will teach you much about flight dynamics, aircraft handeling and radio equiptment. You can also use it as a test bed for the autopilot system if needed.
Good luck,
