A 2 ounce muffler can be fabricated from a mousse can or any other similar container. An 800 RPM gain in engine speed can be expected. Overall engine performance is improved yet the noise level is reduced over that of a stock muffler.

Foam wing construction steadily becomes more popular with R/C modelers. This is a method of producing strong, light weight, accurate, inexpensive wings with a minimum of effort. There are as many methods of making foam wings as there are people who make them but the basic concepts are all the same.

A scale-like leaf spring tail wheel can make the difference in an average looking model or an outstanding model. Construction is simple and rewarding using readily available material.

Every aircraft modeler needs a simple, easy to use fixture for balancing a new model. The "Tinker Toy" balance jig is like child's play.

A Futaba Conquest or Attack transmitter or buddy box can be converted for use as a controller for the Dave Brown R/C flight simulator, Flight Unlimited, Microsoft Flight, and several other simulators and games.

Every aircraft modeler needs a simple, easy to use fixture for constructing wings. The wing assembly jig, if used properly, can help to assure that wings are built straight and warp-free.

A fuselage assembly fixture which will speed construction while maintaining the symmetry and straightness of the fuselage can help any model builder. The fuselage assembly jig is one item that every modeler, especially builders of pattern planes, should have.

The use of a transmitter tray has proven to improve the precise movements of the sticks for a lot of people. With a design that is inexpensive and simple to build, it may be worthwhile to try one.

Expanded scale loaded voltmeters have become the accepted means of field checking a receiver battery pack. A better method of checking a Ni-Cd battery pack is with a "loaded" digital voltmeter with an inherent higher resolution. The problem with using a loaded digital voltmeter is that no one makes such a device. This should not be a deterrent to modeler.
