4. Setup and Assembly
The E-flite T-28 Trojan 1.2m comes largely pre-assembled. Follow these general steps for final setup:
- Unboxing and Inspection: Carefully remove all components from the packaging. Inspect for any damage.
- Wing Attachment: Securely attach the wings to the fuselage according to the detailed instructions in the full manual.
- Landing Gear Installation: Install the landing gear. The T-28 Trojan features functional retracts.
- Receiver Installation (BNF Basic): If you have the BNF Basic version, ensure the telemetry-capable AR631 receiver is correctly installed and bound to your Spektrum DSMX/DSM2 compatible transmitter.
- Battery Installation: Install a compatible 3S or 4S LiPo battery (2200mAh to 3300mAh recommended) into the battery compartment. Ensure it is secured to prevent shifting during flight.
- Control Surface Checks: Verify that all control surfaces (ailerons, elevator, rudder, flaps) move freely and in the correct direction relative to your transmitter inputs.
- CG (Center of Gravity) Check: Perform a balance check to ensure the aircraft's center of gravity is within the recommended range. Refer to the full manual for precise CG locations.

5. Operating Instructions
The E-flite T-28 Trojan 1.2m is equipped with advanced technologies to enhance your flying experience.
5.1 Flight Modes and Technologies
- AS3X Technology: This system works behind the scenes to smooth out the effects of wind and turbulence, making the aircraft feel larger and more stable.
- SAFE Select Technology (Optional-Use):
- Beginner Mode: Limits pitch and bank angles, and self-levels the aircraft when controls are released. Ideal for new pilots.
- Intermediate Mode: Offers more freedom in pitch and bank, but still provides self-leveling.
- Experienced Mode: Provides full control without any pitch or bank limits or self-leveling.
Refer to your transmitter manual for instructions on how to activate and switch between SAFE Select modes.
5.2 Pre-Flight Checks
- Ensure your transmitter battery is fully charged.
- Confirm the flight battery in the aircraft is fully charged and properly secured.
- Perform a range check of your radio system.
- Check all control surfaces for correct movement and trim.
- Verify propeller is securely attached and free from damage.
5.3 Takeoff
For ground takeoffs, position the aircraft into the wind. Gradually increase throttle, applying slight up-elevator as needed to lift off. For hand launches, ensure SAFE Select is active (if desired) and gently toss the aircraft forward and slightly upward while applying throttle.

5.4 Flight
The T-28 Trojan 1.2m offers a wide flight envelope. Utilize the functional flaps for improved slow-speed performance and shorter takeoffs/landings. Experiment with different flight modes to match your skill level and desired maneuvers.

5.5 Landing
Approach the landing area into the wind. Reduce throttle and deploy flaps (if configured) to slow the aircraft. Maintain a controlled descent and gently flare just above the runway for a smooth touchdown.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your T-28 Trojan 1.2m.
- Pre-Flight Inspection: Before each flight, check all control surfaces, linkages, and the propeller for damage or looseness. Ensure the battery is fully charged and secured.
- Post-Flight Inspection: After each flight, inspect the airframe for any damage, especially after hard landings. Check motor and ESC for excessive heat.
- Battery Care: Always follow the manufacturer's instructions for charging, discharging, and storing LiPo batteries.
