PRISM FLIGHT MANUAL
44
PRISM maneuvers by means of variable propulsion through its four to eight U8ii motors.
Each motor is equipped with a 28-inch folding propeller, and motors are arranged in
alternating clockwise (CW) and counter-clockwise (CCW) configuration to cancel rotational
inertia and provide the maximum-possible stability in flight.
The T-Motor U8ii motor system operates on a 48-volt power supply to provide a maximum
thrust of 7.3 kg (16 pounds) per rotor at sea level, for a combined thrust of 29.2 kg (64.4
pounds) in the quadcopter configuration, or approximately 58.4 kg (128.7 pounds) in the
coaxial X8 configuration (this value is approximate due to the reduced efficiency of thrust
when motors are paired in a coaxial configuration). The X-Carbon polymer (quadcopter) or
T-motor P&G Series carbon-fiber (coaxial X8) fixed-pitch propellers are 28 inches from tip to
tip when unfolded.
Propellers are mounted to the T-motor U8ii motors, a pancake-style electronic brushless
designed for efficiency and intelligence. Each motor weighs 200 grams (7.1 ounces) and
has a KV of 85 RPM per volt.
The Watts Innovations PRISM’s unique propulsion design allows users to fly the aircraft
in either a quadcopter configuration, or in an Coaxial X8 configuration with two motors
mounted coaxially to each boom.
PRISM is shipped with a propulsion system that is determined by the user (generally either
a Quadcopter or Coaxial X8). Each is hard-coded and tuned for optimal performance at a
specific mounting location about the central airframe: Front Right, Front Left, Back Right
and Back Left. The mounting locations cannot be interchanged, and incorrectly-mounted
propulsion booms will cause the flight controller to fail a pre-arm systems check.
The propulsion system can be reconfigured by removing two bolts at the attachment point
of each boom.
Removing a Propulsion System:
• Simply remove the two shouldered bolts with a M3 hex driver.
• Repeat for each arm
