User Manual for E-flite Commander mPd 1.4m

Quick Start Guide

The E-flite Commander mPd 1.4m is a sophisticated RC aircraft. Before your first flight, ensure the transmitter is properly programmed, the receiver is bound, and the control surfaces are tested. Always perform a range check and verify the Center of Gravity (CG) is at 85mm +/- 3mm from the leading edge of the wing at the fuselage.

Model Assembly

The aircraft requires final assembly of the landing gear, horizontal tail, wings, and propeller.

• Landing Gear: Install the assembly into the bottom fuselage pocket and secure with the two included M4 x 40mm screws.
• Horizontal Tail: Slide the joiner tube into the fuselage, attach the tail halves, and secure with the two 2.8 x 10mm self-tapping screws.
• Wing Installation: Insert the 10mm x 585mm joiner tube into one wing, slide into the fuselage, then attach the second wing. Secure with M4 x 20mm screws (rear) and M4 x 25mm screws (front).
• Propeller: Install the hub, backplate, and propeller onto the shaft. Tighten the spinner nut clockwise and secure the spinner with the M3 x 30mm screw.

Transmitter and Receiver Setup

The BNF Basic version includes a pre-programmed receiver. For PNP versions, ensure you use a 6-channel full-range receiver. Program your transmitter with a blank ACRO model, set dual rates to 100% (high) and 70% (low), and set throttle cut to -100%.

Binding and SAFE Select

Binding is required to link your transmitter. SAFE Select can be enabled or disabled during the binding process. If enabled, you can assign a switch to toggle between SAFE Select and AS3X modes. Always ensure the transmitter sticks and throttle trims are at neutral before binding.

Operation and Testing

Before flying, perform the following tests:

• Control Direction Test: Verify that moving the transmitter sticks results in the correct movement of the elevator, ailerons, rudder, and flaps.
• AS3X Response Test: Raise the throttle above 25% to activate AS3X, then lower it. Move the aircraft and observe the control surfaces; they should move to counteract the movement.

Maintenance and Troubleshooting

Regular maintenance ensures flight safety.

• Motor Service: Disconnect the battery before service. Remove the spinner, propeller, and cowl to access the motor. Secure the motor with the four M3 x 35mm screws.
• Troubleshooting: If the aircraft does not respond to throttle, check the throttle trim and servo travel settings. If experiencing oscillation, check for loose components or an imbalanced propeller.
