How to Balance an RC Plane

Flying radio controlled, or RC, airplanes is a classic recreational hobby. Whether you are an aviation enthusiast or a casual weekend flier, RC planes can teach you a lot about flying, and the basic mechanics of aircraft. Making sure your RC plane is properly balanced is critical for safe flying. An unbalanced plane can be difficult or even impossible to control once airborne. Take the time to check that your model is properly balanced before each flight.

Things You'll Need

Modeling clay or fishing weights
Fishing line

Instructions

- 1
  Locate the correct center of gravity. Your build plans or instructions included with your model will show at what point under the wings the plane should balance. If you don't have the instructions with you, use a point about 1/3 back from the leading edge of the wings.
- 2
  Place your fingers under each wing at the center of gravity point, close to the fuselage. Lift the model and allow it to balance on your fingertips. Note the angle of the plane from nose to tail.
- 3
  Place small amounts of modeling clay or fishing weights in the fuselage where needed until the plane balances with the nose level or pointing slightly toward the ground. Make sure to secure the weight you add so that it won't move during flight and upset the balance.
- 4
  Loop some fishing line around the nose and tail to check the roll balance from wingtip to wingtip. Suspend the plane from the loops and add any weight as needed to the wings until they are level.
