FMA RAZOR - Specifications

2
Thank you for purchasing the FMA Direct RAZOR ARF series R/C aircraft. RAZOR is available in fourteen basic kit
or Almost-Ready-To-Fly configurations, ranging from a hand-toss glider for youngsters to a 600 Class
Performance Electric capable of speeds in excess of 60 MPH in level flight. RAZOR is designed using state-of-the-
art computer modeling to be extremely efficient, versatile, and rugged. Injection molded of ARCEL
(TM)
, a
revolutionary new type of foam composed of expanded polystyrene and polyethylene, the basic airframe is
extremely strong, yet highly flexible. Extensive flight testing by FMA engineers has demonstrated the incredible
shock absorption and impact resistance of RAZOR by spinning the airplane in from as high as 100 feet directly on
the nose with little or no damage to the basic wing structure. With the addition of a 22” carbon fiber spar in-
cluded in the kits, RAZOR is arguably the most durable R/C aircraft available today. RAZOR is available in blue,
white, and gray and requires no painting, covering or finishing of any type. However, unlike other foams,
ARCEL
TM)
can be painted or trimmed with a wide range of paints including Krylon™ from your hardware store.
Additionally, ARCEL
(TM)
is not damaged by application of CYA cements or glow fuels.
All basic RAZOR kits ship complete with airframe, elevons, winglets, ABS plastic tray and canopy, pushrods and
related hardware. Kits are configured to support slope soaring, park flier, 400 Class electric motors, or 600 Class
electric motors. The various ARF products ship with either 1) propulsion - which includes motor, ESC (electronic
speed control), propeller and propeller adapter, and 7 cell battery power pack, 2) flight pack - which includes
receiver battery (slope model), receiver, and servos, or 3) a combination of both propulsion and flight pack
equipment. The motorized versions include 1) a 280 Class, 6V electric motor, 2) a 400 Class, 6V electric motor, 3)
a 600 Class, 7.2V “endurance” motor, or 4) a 600 Class, 7.2V “performance” motor. The following table itemizes
the package contents and basic flight characteristics of the latter three electric, motorized ARF models. The
information presented in this table and any other specifications listed in this manual were current as of the date
the manual was written and are subject to change without notice. Furthermore, at the time this manual was
constructed, FMA was working on delivering additional models that include ARF electric models complete with
transmitter, receiver crystal and charger, as well as ultra-high-performance gas powered kits.
