Balanced Weight
Checking the weight of your airplane will improve the control of your RC airplane. Balance the plane on your fingers, with your fingers placed at each wing and equal distance from the body. If the nose is straight or at a slight downward angle, the weight balancing is correct. If the nose is at a downward angle greater than 33 degrees, you need to add weight to the back of the plane. If the nose faces upward at greater than 10 degrees, add weight to the front of the plane. Small metal weights can be purchased from a hobby store and attached to the front or back of the plane to balance the weight.
Check Before You Launch
Be sure to make sure all your pieces of your RC airplane are securely attached before you take off. Turn on your airplane and your transmitter, to be sure the batteries are operating properly. To check that the range of your transmitter is strong enough for your plane, you should be able to control the flaps of your plane when you are between 50 to 75 feet away, without the remote control antennae being extended. If you can not do this, replace your batteries. If you still can not do this, another plane in the area may be flying on the same frequency as you, and you should find another location to fly your plane.
First Flight
Get a feel for how your plane flies. Every RC airplane is slightly different. Fly it just a slight distance first, watching for if it tends to sink or rise without adjustments being made to the flap controls for the wings on the remote. Learning the general differences in the flight path of your plane will help you determine how much to adjust, when steering and landing your plane.
Wind
Strong wind is not your friend when flying an RC airplane. When taking off and landing, if there is a slight breeze, be sure to fly your plane into the breeze for both actions. If the wind is heavy, this is not a good day to fly your plane. It will make the plane hard to control and increase the risk of you damaging your RC airplane.
