Aircraft Frequency Identification Those r/c modelers who have several airplanes and several transmitters can avoid selecting the wrong transmitter by placing the frequency number on the model, such as the wing, rudder, or nose.

Gluing Hinges in Place To prevent CA gluefrom seeping into the hinge pivot and locking it up, place a drop of oil or petroleum jelly in the pivot part before gluing.

Another Hinge Gluing Tip To easily get glue into the hinge slots, take a plastic drinking straw and cut it into pieces about 2 or 3 inches long. Fold over one end of the straw, and then put some epoxy into the open end of the straw. Flatten the open end, then insert it into the hinge slot.

This allows the clunk to still move for inverted flight, but it can't become lodged in the front anymore.

Bending Wood To allow you to bend a piece of wood in a curve without cracking it, first thorougly soak it in a mixture of water and ammonia. Some people keep a long PVC tube filled with this mixture so it is always on hand.

Cutting covering Cut covering on a piece of glass for the best edges. Take a blade from a disposable razor and glue it between two pieces of wood. These blades last much longer than X-acto blades for cutting covering. Put masking tape on bottom of the straightedge to prevent slipping.

Large Clamps To clamp wide parts such as fuselages, put two 90* brackets together to make a U shape and clamp them together with a C clamp.

Holes in Dowels Having trouble drilling a hole through a dowel without it slipping first? Simply clamp a clothespin where the hole needs to be and drill through the clothespin.

Leaky Needle Valve Sometimes air leaks from where the needle screws into the body. To solve this put a piece of fuel tubing over this part to seal it off.

Cheap brushes Save old toothbrushes for several uses such as engine cleaning and epoxy brushes.

Servo connections Some planes require several servos in the wing to plugged in each time the plane is assembled. To make the task easier attach pieces of colored tape to each connector. Also you can label what servo the connector is for on the tape. Now all you have to do is match the colors.
