The Osprey 3000 RES
is a beautiful new 3 m glider which is a delight to look at and a joy to fly. Its excellent aerodynamics make it a stable and easy to fly model with impeccable thermal performance, and a surprisingly good speed range.
Like its predecessor the Circle Dancer 3000 this models is a beautifully constructed balsa and carbon almost ready to fly version of the venerable Bubble Dancer by Dr Mark Drela. The RES
appellation indicates that this version is controlled using Rudder/Elevator/Spoiler controls. The wing has generous dihedral and a large central spoiler fitted, keeping to the intent of the Drela design. The Osprey 3000 RES has beautifully built wing with a substantial carbon spar and carbon DBox, making it rigid and strong enough for a sensible winch launch.
The fine fuselage consists of a lightweight Kevlar, glass, and carbon pod molding with a small pylon for mounting the wing above the fuselage, to reduce interference drag. The fuselage nose incorporates a large (18 cm long) hatch to allow easy access to the battery, receiver, rudder and elevator servos. The hatch is very nicely molded from carbon fibre and incorporates a positive attachment system. The fuselage has a molded carbon tailboom incorporating a small pylon for the tailplane/horizontal stabiliser. The pushrod outers are bonded in place, and all the tail pushrod hardware is supplied.
The tailplane is a feather weight built-up balsa and carbon construction, covered with lightweight transparent film and is supplied ready to bolt onto the rear pylon mount. The tailplane includes a ready hinged elevator for faster pitch response.
The Osprey 3000 RES wing is expertly constructed from balsa and carbon, with beautifully applied transparent film covering, in contrasting colours. The centre panel incorporates a large spoiler to give good approach control. The centre and mid panels include carbon Dbox structural elements which considerably strengthen and stiffen the wing, allowing the model to be flown at higher speed and in windier conditions. The standard of construction is excellent, and the prefabrication is very complete. The only things left to do are gluing the tailboom to the pod, installing the control surface control horns, fabricating linkages for the spoiler, and fitting the RC, battery and towhook.
