For the slope flier who doesn’t want to build and wants to have the best in an all composite yet versatile ship, the Sparrow C, this is the way to go! This all-composite ship features a fiberglass/Kevlar fuselage and pre-painted fiberglass and carbonfiber sheeted blue foam wings. The wing is completely finished and painted and is ready for servo installation. The ailerons are precut and beveled and servo bays are cut with the wire holes ready. The wing is finished in white paint so very little is left to the modeler. The wing is beautifully built and light in weight, utilizing the RG15 airfoil modified at the tip for optimum performance. The composite V-tail is pre-painted, and bagged with fiberglass, with the elevators cut out, ready for hinging. Just glue together the two V-tail halves you’re ready to go. All you do to complete the kit is to mount the wing and tails, do a little finish work (painting of the fuselage is nice, but optional), and set up and install the radio system. This is a very high quality sailplane and a wicked fast, wicked clean flier. As with all the Sparrow kits, the hardware is complete with a full set of instructions and full-sized plans.
The airfoil used on this Sparrow is the RG15. It provides an increased speed range and excellent handling. Using three servos (two in the wing) gives the Sparrow more precise, crisp aileron control, the ability to use the ailerons as flapperons or spoilerons, and leaves room under the wing saddle for ballast.
We chose the RG15 airfoil to give you a higher top end, yet with the use of camber control, you retain the low speed and thermalling ability that has made the Sparrow such a well-liked sailplane. To achieve the best performance of this more advanced Sparrow, we recommend the use of two servos in the wings. Any good micro servo will do nicely; with two wing servos and a programmable radio, the Sparrow can use camber changing to slow down for thermalling and/or light lift. The control surfaces can also be used as flapperons or spoilerons, shortening the requirements for the landing approach. You’ll have the opportunity to fly slopes with less-than-ideal landing areas. An interesting mix that’s particularly useful is to couple the flapperons to the elevator for a little down camber when you pull up elevator. In slow flight, this allows the Sparrow to turn slower and flatter; in fast flight, a tighter turn will result.
Especially designed for the demands of inland slope flying, the Sparrow will fly in light lift and is capable of thermalling . Due to its light 23 ounce all-up weight, the Sparrow will fly in very light lift, yet it will also withstand high winds when ballasted, and provide high speed performance that will satisfy even the most experienced slope pilot. The primary design goal in the creation of the Sparrow was condition versatility, and test flights have proven that this challenge has been met. Beauty, performance, and versatility make this a must-have plane for the slope enthusiast.
The Sparrow in any configuration is a very clean sailplane. Though the wing loading is usually fairly low, allowing the Sparrow to fly in light lift conditions, adding ballast to this beautiful little slope cruiser will make it go fast! In good strong conditions with full ballast, the Sparrow will give the larger all-out racing machines a run for their money!
All-around flight characteristics of the Sparrow C are similar to the Sparrow 2 with faster roll rate and improved handling. This glider is designed for a wide range of flying conditions. It is very easy for the intermediate to fly, and will delight you with its smooth flying characteristics in a wide range of wind and lift conditions.
Sal Says:
This new Sparrow is the one I fly. I love Sparrows! You can take them to any slope and have some fun. The Sparrow will thermal in light lift and go fast in strong lift. Carry a Sparrow C and a ballast kit, and you’re ready for any wind or slope! The Sparrow is one of those rare ships that performs flawlessly, a perfect sailplane.
