Beschreibung

Based on a high-strength aluminum frame with optimized torsional stiffness and minimum weight the HD 500 CELL DBDS with its new Direct Belt Drive System sets standards in the 500 heli-class segment. Apart from a neat outer appearance the main development focus was on the construction of efficient yet weight-saving components.

It is for example possible to install a 48,9mm engine. The battery will be mounted upside down to enable an optimized center of gravity adjustment . The rotor head is a completely new design taking into consideration the latest trends on the market. A seperate swash locker arm will be available as an additional option. While focusing on the belt drive, the main objective was to ensure a very smooth and silent sound eliminating any noise like that originating from a traditional drive system. Precisely manufactured and light-weight aluminium belt wheels combined with a 18mm belt care for highest quality and silent operation. 3 bearing blocks for the main rotor shaft and a contra bearing on the engine ensure no loss of torque and maximum power on the main drive. A high innovative but simple belt-tension unit was designed to guarantee a perfectly tight tail belt under all conditions. The engine and ESC block features additional cooling ribs for a more efficient heat dissipation. Designed for 465mm up to 500mm blades the HD 500 CELL DBDS is perfect for extreme 3D but can also be flown with low RPM. It is the ultimate “toy” for all kind of pilots and leaves no wish open.

After years of successfully selling a variety of Helicopter models to customers located worldwide, HD Helicopters which is currently located nearby Stuttgart/Germany has announced the development of an amazingly engineered brand new high end class 500 3D helicopter, which is scheduled to be delivered by end of November 2013. The new model will be designed in a battery version only and can be flown with 4 to 6s LiPo batteries, in addition the top of the line materiel in aviation such as certified Aluminium and Carbon will be used.
The goal of HD Helicopters is not to establish another typically known or existing helicopter model but to provide a brand new and high innovative design which will set and raise the bar in the market of helicopter models.
