Maintenance
|
- Pre-flight
is convenient with all critical areas
within easy reach.
- The
stressed skin construction is robust and
all systems are simple and reliable.
Maintenance and overhaul can be performed
on-site by your local suitably trained
licensed mechanic (A&P) using Brantly
parts and common aviation materials and
techniques. The same thing goes for the
replacement of all life-limited parts.
- Ground
handling wheels allow for easy
maneuvering. Trailering is a cinch with a
standard 8 ft trailer once the outboard
blades have been removed.
- Only one
life-limited component has a service life
less than 2,500 hours (it's 1,200 hours).
All other life-limited components are
either 2,500 or 3,250 hours.

Engine &
Transmission
|
- The fuel
injected engine is mounted vertically
instead of horizontally like other
helicopters in this class. The rotor is gear
driven by a transmission, not
belts.
- Both the
tail rotor drive shaft from the main
transmission to the intermediate gear box
and the drive shaft from the intermediate
gear box to the tail rotor gear box are
"splash lubricated" and
illustrate the eloquent and clean
engineering approach Mr. Brantly used
when designing the B-2B. Both shafts have
a worm gear that carries the oil from
their common oil sump (the intermediate
gear box) and allows it to gravity drain
back to the intermediate gear box.

Main Rotor
|
- The unique
two section doubly articulated main rotor
blade is responsible for the excellent
quality of ride. The outboard blade is
fully articulated and the inboard blade
also has a flapping hinge.
- The
inboard blade is set at an angle of
incidence 4 degrees greater than the
outboard blade. Just like the twisted
blades that are used on the "big-iron"
helicopters
- The rotor
brake control is a ratchet-handle just
like what you'd find in a sports car.

Cabin &
Accommodations
|
- There's no
need to stuff your tools or clothing
underneath or behind the seat. The 6
cubic foot baggage compartment. It's
certified to hold 50 pounds
(22.7 kg).
- Absolutely
excellent visibility.
