Electric R/C Airplanes Applications.

FEATURES

Designed for electric aiplanes using reverse rotation 550-size motors
Converts the rotational speed from the motor to the propeller,
making the motor more versatile and efficient than a direct drive
system. It is capable of delivering more thrust and longer
flight times by swinging larger, more efficient propellers.
Dual ball bearings and precision machined aluminum prop hub provide
true, vibration-free rotation.
Open housing for optimum cooling and easy pinion changes
Compact, lightweight, and highly durable
Extended prop shaft provides plenty of room to hold prop, washer, and
nut.

DESIGNERNOTES: "Does the gearbox require a reverse direction motor?"
Our motors are timed to provide a higher RPM. That is why we had to have a
reverse motor. Some other motors will turn the same RPM forward or reverse.
It just depends on what motor he is using whether he needs a reverse
rotation motor. per MH, R&D 7/00 AMC
