Sonic Cruiser (oz11817)

About this Plan

Live Wire Sonic Cruiser. Radio control multi trainer. Wingspan 66 in, wing area 860 sq in. For .19 to .45 engines.

Quote: "Exciting Multi Control Trainer. Designed by Hal deBolt.

The Sonic Cruiser is the easy way to multi control R/C flying, you don't have to be an expert pilot to enjoy multi flying with this proven design. Here is a model which is quick and simple to assemble, capable of any and all maneuvers and yet handles with the ease of a trainer.

Modern in design, the 'Sonic' uses a symmetrical airfoil for maximum maneuverability and the utmost in stability. Its generous size wing provides the lift to carry the most fabulous of multi equipment or if desired smooth flying with single channel radios and smaller engines. It is capable of perfect manuvers including inside and ouitside loops, axial rolls, true spins and exteneded inverted flight. Ground handling and take offs are superb with the perfected 2 wheel gear or optional tricycle landing gear.

The design engineered structure takes all the drudgery out of the assemly and yet builds up into a light weight unit which can stand the rigors of everyday flying.

Build the 'Sonic' quicker, fly it easier and get the tops in performance."

Quote: "Live Wire SONIC CRUISER Assembly and Operating Instructions. Design notes: Your Live Wire Sonic Cruiser is a top performance multi control R/C model developed to acquaint the beginner to multi with this phase of the flying. The reason that it can be classed as a multi-trainer is that unless the additional controls provided are used it flies and handles very much like a good rudder only design. As a matter of fact, the Sonic can be flown with single channel, if desired. However, once the additional controls are brought into play the model becomes alive and its performance will match the best multi stunt designs. It can be easily seen that this combination is ideal to learn multi flying with and for some really relaxing flying by the experts too.

The Sonic Cruiser design is an inherently stable one. It will fly by itself easily. The maneuverability comes by applying enough control action to overcome this stability. The symmetrical airfoil is used because it has very little center of pressure travel which means exceptional longitudinal stability, also, of course, this airfoil provides the maximum in inverted stability and maneuverability.

The generous sized wing is used to enable you to use the most fancy R/C gear that you may wish and not have to be concerned too much about its weight. At the same time you can have peak performance at a normal weight while using smaller than normal engines, for instance, a .45 engine would only be required at the maximum weight for the model.

The layout of the Sonic has excellent heredity, being based upon our tried and proven Live Wire cruiser design which has been modernized and improved. The Sonic will make you a model which you do not have to be afraid of and one which should provide you with many enjoyable flights!

The structure of the Sonic has been kept as basic as possible to allow the utmost in utility with the quickest assembly time practical. It has been design-engineered to put the strength where it is needed and keep the light weight where ever that is possible.

All assembly methods are as simple and sound as the art knows today so that you can get into the air as quickly as possible with a most useable airplane.

There are two optional items which you may use if desired. The drawings show both, a 2 wheel landing gear and the latest in tricycle gears with a steerable nose wheel. The 2 wheel gear is by far the simplest and also lighter in weight. With this one you can expect excellent take off characteristics and the model taxis exceedingly well. It is a most useable arrangement. For those who want the very latest in landing gears an optional tricycle arrangement is shown. This one works well too, and all the details are given for its usage.

The second option is a trim control for the elevators. This is a very worthwhile addition for those who have 10 channel radios but not required for excellent performance with the Sonic. Its advantage is that it gives precise longitudinal trim control for the model under all conditions whether upright or inverted. Excellent results can also be had by the use of a trimmable and self-neutralizing elevator servo with radios of fewer channels.

The choice of power for the Sonic should be given some serious consideration. For 9 out of 10 cases, it should not be necessary to use anything larger than a .35 engine, this powered the original model with plenty of reserve. The consideration is that this is an extremely clean flying airplane and, as such, it does not require nearly as much power as would some other design..."
