The Circle Dancer 3600 Glider is a beautifully constructed 3.6m span balsa and carbon almost ready to fly version of the Bubble Dancer by Dr Mark Drela. The model available on this page is the pure glider version, with rudder, elevator and flap controls, not electric as shown in the photos. This new 3.6m version is an all new structural design, with stronger and stiffer carbon Dbox wings and other strength improvements.

Although the structure is simplified in comparison to the original BD design, the aerodynamics are very similar, and the Circle Dancer 3600 is a stable and easy to fly model with impeccable thermal performance, and a reasonable speed range.

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 motor, battery, and rudder and elevator servos. The hatch is very nicely molded from carbon fibre and incorporates a positive attachment system. The fuselage has been updated to use a molded carbon tailboom incorporating a small pylon for the tailplane/horizontal stabiliser. The pushrods are supplied and all the tail pushrod hardware is supplied. The new fuselage has reduced the fuselage weight, improved strength, removed weight from the tail extremity, and has reduced the size of the shipping box, allowing us to post the model overseas more easily.

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 is of improved construction and includes a separate ready hinged elevator for faster pitch response.

The wing is expertly constructed from balsa and carbon, with a strong carbon DBox front part and beautifully applied transparent film covering, in contrasting colours. The centre panel incorporates large flaps to give good approach control. 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, gluing the fin, installing the control surface control horns, fabricating linkages for the flaps and ailerons, and fitting the RC and battery.

Circle dancer 3600 Glider

The Circle Dancer 3600 arrived two days after I placed the order. Inside a stout box I found the model, protected by two layers of bubble wrap, in perfect condition. The model is beautifully built and covered. In particular the carbon wing leading edge and the fuselage boom have a glossy finish almost too perfect to touch. The model was easy to assemble though I took my time to get it just right. The manufacturer’s data sheet laid out the control throws and cg position. Interestingly it also said that the glider wing is much stronger than the wing of the electric version.
The first flights were made on a gusty day so know that the model can take a good strong launch. The model is a smooth flyer, indicating lift well and is easy to land thanks to the large flaps. Overall I’m very pleased with the Circle Dancer 3600.
