Canadian Home Rotors Baby Belle / Safari

 

chrsafari


Canadian Home Rotors Inc. (CHR) are the manufacturers of the Safari helicopter. A scaled Bell 47G look alike, that has consistently placed at the top of the custom built helicopter pile. Originally called the Baby Belle, but after objection from Bell Helicopters the name was changed to Safari.


A two seat side by side enclosed helicopter, the 4130 steel tube frame cabin monocoque and boom can be made up in the home workshop while awaiting delivery of the factory built main rotor and tail rotor gearboxes along with the main rotor head and blades. Main rotor is gear driven, tail rotor is shaft driven. Tail boom is steel tube. The main rotor blades are skinned all-aluminium with extruded aluminium leading and trailing edges. Blades are shaped by one solid rib each 6 inches from the root to three feet outboard, then one rib per 12 inches to the tip. Each blade contains 16 ribs. The main rotor flies at 500 rpm, and tail-rotor at a 5.4:1 rpm ratio.

 

The four foot diameter, 4 inch chord tail rotor blades  are stainless steel, with a solid steed spar running out 6 inches from each blade root and wrapped with stainless sheeting to form the airfoil. The main rotor gearbox includes clutches and engine fan. The cabin bubble is sourced from Nordam Plastics, manufacturers of the original Bell 47 item. The bubble is an actual Bell 47 series enclosure. A Delta teetering system provides the control. Aluminium castings are used in the swashplate-controlled main rotor system.


The instrument panel carries operational instruments and a main transmission temp indicator and chip detectors for the main and tail rotor gearboxes. Engine, seats and cockpit fittings were generally the items sourced from written off Robinson R22. Fuel capacity of 28 US gallons is carried in two 14 USG aluminium tanks aft of the cabin.
Skid landing gear is built with 2 inch diameter tubing, the bottom horizontals black anodised.


In 1996 the kit price was US$38,000.

 

CHR-Safari

 

CHR are constantly improving the Safari with experience, including increased service intervals on the main rotor gearbox. Build weight is always slightly different between machines but generally just under 1,000 lbs., which allows a useful load of better than 500 lb. The 12 foot span blades feature an eight inch chord and weigh 40 lb. each.
The Safari is powered by a Lycoming 160 hp aircraft engine, maintaining the highly trustworthy flying abilities of this classic design. Cruising speed is 80 mph with climb rate of 1,000 fpm & an operating ceiling of 10,000ft. Max. speed is 100mph.


A US corporation, CHR International Inc acquired Safari Helicopter.  The owners of CHR International Inc., Bobby and Delane Baker, have been involved with Safari for several years.  Murray Sweet, one of the original developers of the Safari, was to remain involved with the new company as a technical consultant, as will other long time members of the Safari team.


Much of the production was to remain in Canada, with assembly and flight training continuing in Marianna, Florida. They reduced the dealership requirements in most parts of the world, with positive results.
