Discus Launch GliderThe ELF is a small discus-launch glider ideal for sport flying while on travel or in your neighborhood park. Drela's HLG glider design, the Apogee. Due to it's low weight, with a scant wing loading of 2. Pod - Features a transparent yellow or white injection-molded pod. A custom carbon boom is connected into the pod, on which the receiver battery a one-cell mAh LiPo pack with an integrated charging circuittwo servos and the receiver are mounted on. A removable nose cone allows for easy access to RC components. Wing - Carbon D-Box construction and carbon-capped balsa ribs combined with a vertical balsa grain spar provide a stout one-piece wing. A carbon "T" launching blade that is capable of being installed on either wing, allows for comfortable launches. The wing is professionally covered in Violet, Blue or Red Oracover to provide strength and stiffness. Tail - The tail surfaces are composed of light-weight foam, which is reinforced with carbon, fiberglass and then vacuum-bagged. A one-gram miniature v-mount allows for the full flying stabilizer to give the pilot infinite pitch control. Carbon push-rods are pre-installed.

The thought that one can hand launch a model glider to ft altitude seems amazing — but is possible with Discus Launch Gliders DLGs. To launch one holds the glider by a finger grip on a wing tip and then one spins around as throwing a discus. With the gliders weighing around g 11oz the 25g force comes out at 7. Also look at my flight later in this instruction. The need for high strength, light weight and clean aerodynamics means that a composite built model is needed. I had started with a cheap HobbyKing model with conventional covered balsa wings which was great for testing interest but was higher drag and hence gave poor launch heights. Hence shorter flights and less time to find some lift. The kits comes with the moulded wings and fuselage complete and with hardware to build the control linkages. The rudder also has to be attached to the fuselage - that was a bit more difficult with my kit. The mount for the all moving tail has to be glued in place. However the major activity is installing the radio gear and control hardware. I did several things differently to the instructions in order to save weight and make a neat installation. I hope some of these will be useful to other builds of DLG kits. In particular I mounted all 4 servos in the nose to reduce the nose weight required and hence reduce the overall weight. I also used a neater, more maintainable and lighter servo mounting system. The control horns were all replaced with lighter carbon ones and their length was carefully set to match the servo arm length and movement that was possible within the confines of the nose cone. Before starting I weighed and found the centre of gravity COG for each of the parts, plus servos, radio and battery. I put these into a spreadsheet so I could see where the final model COG was likely to be. From this it became clear that I would need less nose weight if I put the aileron servos in the nose rather than the wings. I had seen comments on doing this but no examples— a gap that I hope this instructable fills. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The Blaster 2 has an all moving tailplane mounted on a carbon V mount. The mount has to be fitted before the rudder as it slips over the boom. This was because the V mount assumes parallel top and bottom surfaces and the elevator was essentially triangular in cross-section from the mounting plate to the trailing edge. To correct this I filed a piece of 0. See photo above. The target is to have the trailing edge of the elevator 5mm in front of the leading edge of the rudder. This position was found with rudder fitted loosely. Masking tape was wound around the boom forward of the mount so it could be positioned easily with adhesive applied. I prefer epoxy to cyano as it gives a longer handling time and a stronger joint. I had also sanded the mating surfaces for a good joint. In order to get the elevator flat relative to the main wings the mount was fitted with the main wings in place and the elevator attached to the mount. The alignment was checked carefully before leaving for the epoxy to set. The rudder glues into a slot the rear of the carbon tail boom.
Write a review. Review by: Philip Whiteley. I ordered an Elf from Hyperflight, it was dispatched within 24 hours and arrived at my doorstep in Australia in about a week. The model was well packed and arrived undamaged. The Elf is a work of art and no doubt it will fly as good as it looks. The service that Neil provides is first class and my other purchases have all received the same attention. I will not hesitate to purchase from Hyperflight again in the future. Review by: Trevor. ELF ordered on Friday and received on Monday! Very well packaged in a strong cardboard box. I have to say I have used Hyperflight in the past and have always found the service excellent. Review by: Martin Pile. Great little glider to put togetheralthough manual could be updated as pointed by other purchases. No missing parts and arrived in a very sturdy box and in good condition by parcelfarce within a couple of days of ordering. Nice to know the glider is well rated on RCGroups and Hyperflight as well. Review by: Stephen Crisp. Service was outstanding. The ELF is a beautiful creation - not flown her yet, as I'm awaiting my new transmitter. Final weight will be around 94 g. Build is fairly straightforward. Complimentary wing bags are a nice touch. Packaging is excellent and ELF arrived undamaged. Bluebird servos are also of a superb quality. Review by: Nick. Elf finish and fit is first class, build is easy, its all but finished. The instructions and accompanying photographs make final assembly easy. This coupled with an inspired design make this first DLG model a great choice. I'm very pleased. Review by: Mike. The Elf seems hard to get a hold of so as soon as she was available, I did not hesitate to order : The package arrived within 5 working days. The packaging was simple and effective, thus reasonably light.

It only takes a couple of evenings to build and has a removable wing so you can easily transport it to the flying field! While it is possible to fly this model with a 4 channel radio, you will need to fly with a forward CG and use a y connector to slave the ailerons, which will eliminate the flapperon function. I recommend at minimum a Spektrum DX6i or equivalent Flysky i6 may be sufficient with a micro receiver. Stay tuned for an upcoming build article at Flitetest.
