Im flying a little control line. One of my favorite planes is a 35 powered flitestreak. Im starting my takeoff crosswind. As I takeoff for the first few feet I have very little line tension. After I get up a litte speed the tension improves and after one lap I have about 2 pounds of tension I would estimate. After the engine dies again the line tension slacks off and if it dies on the upwind part of the circle I sometimes have to back up to maintain tension. I could offset the engine but that wouldn't help when the engine is off. Should I have more rudder?, Tip weight? Will listen to answers.
