Packages & Optional Accessories

The Bergen R/C Helicopters Twin Observer is a dedicated Camera Ship.  Based on our popular Intrepid Gas mechanics, the reliable Zenoah/Bergen G52 engine, and 810 mm V-Blades, we have added a front mounted pan and tilt system to give you a machine capable of lifting up to 20 lb useful payload of camera equipment and radio gear.  The camera mount can handle up to 8 Lbs, with the additional payload needing to be located so as to maintain CG.  The dimensions of the camera mount allow a camera up to 5 7/8" wide, 6 " tall, and 12" long.

Putting the camera equipment on the front keeps you from having to utilize a tall landing gear and the inherent problems associated with it.   A front mounted camera also allows you a clear 270 degree field of view, and the pan and tilt system is vibration isolated from the mechanics with 4 heavy -duty isolators to give you the clearest picture possible.

The Twin Observer uses G10 stacked frames and a torque tube drive on the tail.  It also comes with all the standard features from the Intrepid line of helicopters, including a self aligning clutch system with a factory installed clutch liner, a triple bearing block supporting the drive pinion and start shaft, a 10mm fully hardened hollow main shaft, an all aluminum head and blade grips, and an aluminum push-pull control system designed to eliminate any swash plate interaction through the full range of travel.   The 32 oz. fuel tank provides a flying time of approximately 30 minutes. Additional fuel tanks can be added in a saddle configuration for extended flighttimes of 2 hours or more.  Of course this reduces your total payload capability.

The Twin Observer comes pre-assembled and test flown from the factory.  It is NOT available as a kit, Only minor assembly is necessary after you receive the helicopter.  We will install and use your radio gear for the test flights.

Listed below are five of our most popular purchase packages and some additional options.

TERMS OF PURCHASE:

 The total cost of all radio gear and optional parts to be purchased must accompany the initial order. We also require a minimum deposit of $1500 to begin the building process.  The remaining balance plus shipping and handling fees are due at time of shipment.
