Our new CUMUL DLG will easily fulfil your dream about a handy model you could fly virtually anywhere, about a model you could pack for your trips that would work with even the most basic two-channel radio...And do not forget - this RC hand launch glider will get you in shape in no time - the thoroughly performed discus launch is quite a bit of a sporty feat as well!
A small RC hand launch glider kit is a great thing for anybody who wants to build his models by himself in the old-fashioned way of balsa, plywood, sticks and a little bit of carbon composites. The building is easy a goes forward quite nicely. CUMUL DLG maybe is not an ideal very first model for a newcomer without any previous experience, but if you have built at least “something of balsa and sticks”, you should not have any problems. There should be no problems mastering the discus launch once your CUMUL DLG is ready to fly as well - we included a thorough illustrated appendix showing how it is done in the instruction manual.
Designed and manufactured in the Czech Republic. .
This builder’s kit of a high-performance RC hand launch glider is a perfect project for a modeller wanting to build a really good for sporty and “Sunday“ flying. The well-thought design with CNC-cut interlocking parts fitting together like pieces of a puzzle makes the building a breeze. The ribs and riblets are supplied with jig tabs allowing building the wing (featuring an undercambered profile) directly on a flat working surface - and all that with a built-in washout!
The front part of the fuselage is a simple „box“ of balsa sides, top and bottom sheets and plywood formers and braces. The servo and battery compartment are located in the front part under the removable hatch with a magnetic lock. The tail boom is a carbon tube with liteply pylon for the horizontal tailplane. The tow hook for the bungee launch is also included in the kit.
The one-piece wing sports the YA0801 wing section (“tailored” to needs of RC hand launch gliders) is of, now we can say classic, design with CNC cut balsa ribs, carbon tube main spar and beech dowel leading edge for high strength at very low weight. The wing is secured to the fuselage with a plastic bolt. The discus launch pin can be installed on the left wing tip (for right-handed pilots) or to the right wing tip (for left-handed pilots).
The empennage is made of CNC-cut balsa sheets with balsa and carbon reinforcements. The elevator and rudder are controlled by servos located in the fuselage with piano wire push rods running through the tail boom.
You can use an iron-on film for covering - lightweight Oralight® or similar materials are preferred.
You will need at least two-channel radio to control your CUMUL DLG. Good 6g micro servos (0.7–0.9 kg.cm torque) are required for the elevator and rudder; the servo tray supplied in the kit is tailored to the KAVAN GO-6MG servos.
1S 3.7V 450–500 mAh LiPo battery would make a great receiver battery.
