SIG SUN DANCER 50 Manuals

to 80 inch/ in ounce range, such as Hitec HS-475HB, HS-545BB, or HS-635BB or the Airtronics® 94731Z, 94738Z or 94743Z servos. For the rudder servo we have used and can recommend that you consider using an after-market reinforced plastic servo arm such as the Du-Bro "Super Strength" products. These output arms are available to fit any brand of servo. They are quite strong and work extremely well with this model. The Du-Bro output arms are molded from considerably stronger material and have held up very well in our prototypes. You will also need three 6" servo extensions and one standard Y-harness cord or 6" double link extension for the ailerons. In addition, you’ll also need one 12" servo extension for the aft mounted elevator servo. These after-market items can usually be obtained from either the manufacturer/distributor of your particular radio system or from aftermarket suppliers, such as Maxx Products in Lake Zurich, Illinois. Last, because the Sun Dancer 50 uses a total of 5 servos, we suggest that you consider the use a larger capacity airborne battery pack. A battery pack in the 1000+mAh range will provide ample time to safely fly at least five or six flights during any given flying session. This is a reasonable amount of time for most modelers. Naturally, a larger pack provides more flight time but remember that larger can also equate too heavier. We also suggest that you routinely use an Expanded Scale Voltmeter (ESV) at the field to check the charge condition of your batteries. This common piece of field equipment can save your model! ENGINES & PROPELLERS: The Sun Dancer 50 has been flown with a variety of engines, both 2 and 4-stroke. As everyone knows, there is no substitute for power and the engine sizes recommended for this model all provide good power margins. The practical range runs from 2-stroke engines in the .46 to .53 sizes and 4-stroke engines in the .56 to .72 displacements. Naturally, the larger engines in this range make more power and will fly the Sun Dancer 50 with more authority than the smaller engines. It is simply a matter of how you want to fly the airplane. You also need to choose a propeller size that is suitable for your particular engine, based on the manufacturer’s recommendations. After flying the model and gaining experience, you can experiment with different propellers to find the optimum combination for your engine and airplane. The Sun Dancer 50 was designed from the start for glow engines and provides ample room inside the cowling to comfortably fit most of the popular engines that are available in both 2 and 4-stroke types. COVERING MATERIAL: Your Sun Dancer 50 has been professionally covered with SIG AEROKOTE®. If you live in a drier climate, you may notice that some wrinkles might develop after removing the covered parts from their plastic bags. If that is the case, there is no need to be alarmed. The covering is not defective. This is normal and has and nothing to do with the covering material or how it was applied. Balsawood takes on or loses ambient humidity. Your Sun Dancer 50 was manufactured in a relatively humid region of the world. The wood was therefore holding some humidity at the time the parts were covered and bagged. When these parts are removed from their bags and subjected to drier conditions, the wood quickly loses moisture and the covering may appear loose. This also explains why most iron-on coverings stay tight in the summer only to loosen a little in drier winter conditions. 1 INTRODUCTION Congratulations on the purchase of the SIG Sun Dancer 50 ARF kit! Properly assembled, powered, and flown, the Sun Dancer 50 will quickly become one of your favorite models. The construction of this ARF kit has been extremely well engineered, providing an airframe that is both light and strong. Of course, this translates to outstanding flight characteristics when powered with the recommend engine sizes. The Sun Dancer 50 has excellent take-off and landing characteristics, as well as remarkable aerobatic capabilities. The airframe has been carefully designed to provide you with a model that has a true "zeroed out" feel in the air. This characteristic tends to provide a great deal of confidence when performing those wild aerobatic maneuvers. The engine choice for your Sun Dancer 50 is important. The airplane will fly and fly well on good running .46 ball-bearing engines. As your choice of engines increases in displacement and power, obviously the airplane will respond accordingly. The largest and most powerful engine we have flown in this model is the potent YS .63 four-stroke. This engine, swinging an APC 12 X 6, provides the Sun Dancer 50 with an outrageous amount of power, making it definitely a "throttle management" type model. We do not recommend engines any larger or more powerful than the YS .63 for this model - it simply is not necessary. We highly recommend that you follow the following assembly instructions carefully. We also suggest that you take the time to inventory the contents of your kit, using the included parts information. Finally, the Sun Dancer 50 ARF is not recommended for beginning R/C pilots. If this is your first R/C model, we urge you to seek and use experienced help in both assembling and flying this airplane. Engine Note: Due to the large number of useable engines for this model, we simply cannot cover every possible engine installation. However, the large volume of space provided inside the cowling should make it easy to mount virtually any engine within the suggested size range. RADIO EQUIPMENT: We highly recommend the use of a modern computer radio for this model. Such radio systems allow you to easily set-up and adjust each channel and in addition, pre-program flight control functions to suit your individual flying style. Four channels are required to fly your Sun Dancer 50 - rudder, elevator, ailerons, and throttle. The Sun Dancer 50 requires a total of five servos - ailerons (2), elevator (1), rudder (1), and throttle (1). Standard 40 to 50 inch/ounce servos will work well for this model. However, for better precision, you can upgrade to ball bearing servos in the 60
