There won't be a first few times. With a Cub built by someone who's never learned to properly set up a model plane, there will likely be one quick ground loop, possibly followed by a cartwheel or a nose over. Then it's repair and repeat. That's of course assuming everything is built correctly. You have no idea the value of having an experienced pilot help you on your first few flights. A good instructor will do a thorough "new plane" pre-flight inspection and will maiden it and trim it for you. He'll also help you get the control throws set right so the plane has the right amount of response. That's the first big hump to get over- having a properly flying plane. Then the instructor will start working on your piloting skills which for a Cub need to be fairly developed. If you skip the instructor stage, you'll start out with a plane that likely needs some tweaking to fly right and no piloting skills. That's a bad combination if you plan to bring the plane home in the same condition you left with it in.
