Low power from a power system with an AXI motor

Low power from a power system with an AXI motor


Unbalanced propeller

Propeller is a poor fit on the adapter, too large a bore of propeller for the adapter

Weak motor mount which works as an amplifier of vibration

Motor mounting is loose

Foreign object inside the motor (for instance dirt after landing, metal partical, washers etc.)

Burned motor after oveloading

Overloaded motor


Lack of motor cooling


Use of Li-Poly cells intended for low current loads (high current can cause damage to low current Li-poly cells)

Unsuitable power system design (motor, batteries, ESC)


Balance the propeller

Use a new well balanced propeller or a bush which provides minimal clearance between the propeller and adapter

Strengthen the motor mount, and glue or fix it well to the fuselage

Tighten the mounting screws of the motor.

Opatrně nečistoty vyfoukněte stlačeným vzduchem nebo opatrně vyjměte pinzetou. Pokud se to nepodaří je nutný servis motoru.

Measure the maximum current at maximum throttle with a fully charged battery. The current should not be higher than the current capacity shown in the specification table. If you use unusually high-capacity or high-current Li-Polys the voltage under load can be high even when using the recommended props, and this can result in higher current. In this case use a smaller diameter or lower pitch propeller.

Allow air to flow through the motor, for example using cooling holes in the firewall of the model

Use Li-poly cells with a higher current capability or higher capacity cells which can carry the load.

Use an optimized power system which is recommended for each AXI motor
