how to make plane turn in left hand circles

[Merabethzhuk]

Hi,

I haven't been able to get my plane to turn in a left hand circle. When I fly it, it turns left then just goes straight. I am using the LaserCutPlanes kit. I have not yet made any modifications to it. My plane climbs well, it just doesn't turn. My horizontal stabilizer left tip is 2.5 cm higher than my right tip. I am using 0.081 rubber.

Thanks

I suggest looking at this thread for information on turning the plane: http://www.scioly.org/forums/viewtopic.php?f=245&t=9857

The preferred flight pattern of an indoor duration rubber powered airplane is to fly in counter-clockwise circles (viewed from above). Flying in a small diameter circle is less efficient than flying in a larger one. However, your airplane must not hit the walls, spectators, basketball backboards and other obstructions. A typical flight path for a Wright Stuff airplane is a circle with a diameter of 30 - 50 feet, depending on the size of the gym, whether the bleachers are extended, etc. Remember to account for drift as the airplane may not stay clear of all obstacles if the circular flight path moves 10 - 15 feet, for example, due to air currents inside the gym.

The circular flight path of an indoor duration rubber powered airplane is due to four different factors: 1) torque of the wound rubber motor; 2) left thrust in the motor bearing; 3) left rudder; and 4) stab tilt. These four factors have varying effect during different portions of the flight. Typically the wing of a Wright Stuff airplane is offset to the left of the motor stick about a half inch (viewed from the standpoint of a theoretical pilot on board). You do not want the airplane to be circling in a left bank as this is not an efficient flight path. The offset wing helps prevent this banking. Sometimes wash-in is used to offset the relatively high torque that bleeds off shortly after launch. This is a very slight downward deflection of the outer segment of the trailing edge of the left wing panel.
