There is a control line forum on RCU. When you first learn to fly it is good to have a slow, stable trainer with a small fuel tank. Best deal is to have an experienced flier in the circle to hold your hand for the first couple of rounds and take the handle back if you get dizzy. Most people get over being dizzy. Once you learn to fly some and get a more capable airplane; you can stand still and fly inside and outside loops and figure 8's so long as the fuel lasts. Control Line Precision Aerobatics has a sequence of maneuvers which you fly and the judges score your fight on how well the maneuvers match the rulebook diescription. If you go to the AMA website and click on publications, you can find the AMA rulebook and the CLPA section where the maneuvers and scoring are described. I have heard of several RC pilots who are learning to fly the CL pattern with an RC airplane and finding it quite interesting to do.
