Thrust:The basic theory here is that as the plane SLOWS DOWN in an upline, and the prop gets 'loaded', the torque of the engine causes the plane to pull left / right and/or up/down. This 'pull' can be adjusted out to some extent by changing the thrust line of the engine. You can do this in many ways, but basically you will want to change the angle of the engine to the plane. It's sort of trial and error, but if the plane pulls to the left WHEN IT START TO SLOW DOWN, UNDER FULL POWER, you would want to put in more Right Thrust. It's important to note, the plane must be slowing down under full power. At full power, with a fairly fast airspeed, the torque of the engine is very small compared to the control surface effects. Here's what you can try... enter a verticle at about 1/2 speed, make a nice radius and watch the plane go up.. as the plane slows, advance to full throttle somewhat quiuckly and watch the nose. If the nose pulls to the right, add left thrust and so on. Do this a few times to get the right 'read' on it, then make the change and try it again. In a few attempts you will get it very close. Also, as the CG goes back, the thrust becomes more sensitive. Always adjust CG first, get it where you like it, then adjust thrust. If the CG changes later, check the thrust again.
