Binding and Configuration
As a Bind-N-Fly Basic model, the Ultimate 3D 950mm comes with a Spektrum AR637TA 6-Channel Receiver pre-installed. To prepare for flight, you must bind this receiver to your compatible Spektrum DSMX/DSM2 transmitter.
- Transmitter Setup: Ensure your transmitter is set up for a new aircraft model, with all trims centered and sub-trims at zero. Refer to your transmitter's manual for specific model setup procedures.
- Binding Process: Follow the binding instructions provided with your Spektrum transmitter and the aircraft's full manual. This typically involves putting the receiver into bind mode and then initiating the bind process from the transmitter.
- Control Surface Checks: After successful binding, verify that all control surfaces (ailerons, elevator, rudder) respond correctly to transmitter inputs and move in the appropriate direction. Adjust servo directions on your transmitter if necessary.
- SAFE Select Activation: The AR637TA receiver includes SAFE Select technology. You can choose to enable or disable SAFE Select based on your flying preference and skill level. Refer to the full product manual for detailed instructions on activating or deactivating SAFE Select.
Operating Instructions
The E-flite Ultimate 3D is capable of a wide range of flight maneuvers, from precise sport flying to aggressive 3D aerobatics, thanks to its powerful motor, oversized control surfaces, and integrated AS3X and SAFE technologies.
- Pre-Flight Checks: Before each flight, perform a thorough pre-flight inspection. Check all control linkages, ensure the battery is fully charged and secured, and confirm proper control surface movement.
- Takeoff: For ground takeoffs, apply throttle smoothly and maintain directional control with the rudder. For hand launches, ensure sufficient power and a level toss into the wind.
- Flight Characteristics:
- Sport Flying: Enjoy stable and predictable flight characteristics for general cruising and sport maneuvers.
- Aerobatics: The large control surfaces allow for crisp rolls, loops, and inverted flight.
- 3D Flying: With high rates and proper setup, the Ultimate 3D excels at hovering, harriers, torque rolls, and other extreme 3D maneuvers.
- Landing: Approach into the wind, reduce throttle, and manage descent with elevator. Flare gently just above the ground for a smooth touchdown.
- AS3X Technology: This technology works behind the scenes to smooth out the effects of wind and turbulence, making the aircraft feel larger and more stable, even in challenging conditions.
- SAFE Technology: When activated, SAFE provides bank angle limits and automatic self-leveling, which can be invaluable for new pilots or when regaining control.

Maintenance
Regular maintenance is crucial for the longevity and safe operation of your E-flite Ultimate 3D RC Airplane.
- Post-Flight Inspection: After each flight, check for any loose screws, damaged foam, or bent components. Ensure all control linkages are secure and free from binding.
- Cleaning: Wipe down the airframe with a soft, damp cloth to remove dirt, grass stains, or oil residue. Avoid using harsh chemicals.
- Propeller and Motor: Inspect the propeller for nicks or cracks. Replace if damaged. Check the motor mount and propeller adapter for tightness.
- Battery Care: Always store LiPo batteries at a storage charge and in a fire-safe container. Do not overcharge or over-discharge.
- Storage: Store the aircraft in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
This section provides solutions to common issues you might encounter with your E-flite Ultimate 3D.
| Problem | Possible Cause | Solution |
|---|---|---|
| Aircraft does not respond to transmitter. | Not bound, low transmitter/receiver battery, incorrect model selected. | Ensure binding is complete. Check battery levels. Select correct model memory on transmitter. |
| Motor does not start or runs intermittently. | Battery not connected, ESC not armed, motor/ESC issue. | Check battery connection. Ensure throttle trim is at lowest setting and throttle stick is at zero. Consult full manual for ESC calibration. |
| Aircraft flies erratically or is difficult to control. | Control surfaces reversed, incorrect CG, damaged components, strong winds. | Verify control surface directions. Check CG. Inspect for damage. Avoid flying in high winds, especially if inexperienced. |
| SAFE Select not functioning as expected. | Not activated, incorrect switch assignment. | Refer to the full manual for SAFE Select activation and transmitter switch assignment procedures. |
