Propeller Replacement

The following section describes how to change the propellers on the DeltaQuad Evo.

The DeltaQuad Evo comes with 5 propellers: 1 composite pusher propeller and 4 carbon fiber VTOL propellers. When replacing the propellers, please follow these guidelines.

The VTOL propellers include 2 Clockwise (CW) propellers and 2 Counterclockwise (CCW) propellers.

On the top of the VTOL propellers, there is a marking indicating the propeller's rotational direction.

The bullet-type nut on the propeller adapters is self-tightening, meaning it tightens by turning in the opposite direction of the motor and propeller's rotation. This design ensures that the propellers do not become detached as the motor spins up.

Therefore, to undo the nut on motors 1 and 2, turn it left, and for motors 3 and 4, turn it right.

Mount the propellers in the following positions noting the direction of the propeller as indicated below:

The propellers are attached by removing the motor nut and washer, sliding the propeller on the shaft, sliding the washer on top of the propeller, and fastening the nut.

For the vertical motors (VTOL motors), please make sure to install the washer in the right orientation. The washer has a wider side at the bottom.

Pusher Propeller Replacement

After changing the pusher propeller, a test flight is necessary to verify that the vibration profile is within tolerances. Please contact [email protected] and share the log file for review.

The DeltaQuad Evo pusher propeller is an APC 15x10E propeller, which includes a modified ring for proper mounting on the DeltaQuad Evo pusher motor.

This small ring inside the propeller's mounting hole ensures a snug fit around the motor shaft.

Always ensure the centering ring is present and the propeller fits tightly around the shaft.

Only use DeltaQuad-approved and balanced pusher propellers.

The pusher propeller should be mounted so that it produces thrust towards the rear. This means the top of the propeller (the side with the engraved text) should face the motor, as shown in the diagram below.

All propellers are balanced in our factory by hand. This can leave scratch marks on the propeller blades. This does not indicate damage or that the propellers are used. A sign of damage can be structural weakness such as a bent propeller blade. If you find gouges or missing parts anywhere at the tip, the outboard region, or the trailing edge of the blade you need to replace the propeller.
