2.
Items you must supply to complete this ARF
Epoxy and cyanoacrylate (CA) adhesives and optional threadlock compound.
Common household shop tools (screwdriver, pliers, etc.).
Twelve brushless outer-rotor motors such as the Maxford USA Uranus 28309 motor and electronic
speed controls (ESCs) such as the Maxford USA Uranus 25A ESC, each powered by a 3S minimum
2,200 mAh LiPo battery, or as recommended for your motors, and a LiPo battery charger suitable for
your batteries.
Twelve 8x6-inch 3-blade propellers: six with normal pitch and six with reversed pitch, or as specified
for your electric power system. (NOTE: Maximum propeller diameter is 8-inches.)
A five- (or more) channel radio system with a receiver battery.
Three standard servos: one for each aileron and one for the water rudder.
Three mini servos: one for each half of the elevator and one for the air rudder.
The following extensions, Y harnesses and custom made multi-harnesses are required when using the
recommended electric power system illustrated on page 12:
48-inch extension, 1 piece, or 24-inch extension, 2 pieces (receiver to elevator’s Y-harness)
30-inch extension, 2 pieces (ailerons)
24-inch extension, 1 piecs (receiver to water-rudder’s Y-harness)
18-inch extension, 1 piece (water rudder’s Y-harness to air rudder’s servo)
12-inch Y-harness, 3 pieces (connect elevators, ailerons, and air & water rudders)
12-inch two conductor 1-to-6 multi-harness, 2 pieces (control 12 ESCs from two radio channels)
IMPORTANT: Use two separate channels to control the electric power systems’ throttles.
For example, use your radio’s normal throttle channel for the six front-facing motors and
another channel mixed 100% with your throttle channel to control the six rear-facing motors.
Do NOT attempt to use simple Y harnesses to control all 12 motors from one throttle channel.
The diagram on the following page shows connections for the recommended electric power system’s
throttle and servo lead extensions, Y-harnesses and custom made 1-to-6 multi-harnesses.
