FT AURA 5 LITE AFCS The FT Aura 5 Lite AFCS (Advanced Flight Control System) Description of Pre-Loaded Aura Light Modes comes programmed and installed in your Piraña, making setup a breeze. This highly-refined 3-axis gyro makes the Mode 1 (Sport, Gyro O ) - Gyro gain is set to o . aircraft fly like it is a larger aircraft and in less wind.
TRANSMITTER SETUP WARNING DO NOT ATTEMPT RADIO SETUP WITH PROPELLER INSTALLED. INAVERTENT POWER UP COULD CAUSE DEATH OR SERIOUS INJURY The included FT Aura 5 Lite is designed to work seamlessly with all popular transmitter and receiver brands, however, transmitter setup is significantly different than when setting up a model without Aura. When programming your transmitter, start with a freshly reset, new model memory in your transmitter.
RECEIVER INSTALLATION/SERVO CONNECTIONS Choosing a Receiver Aura will auto-detect modern serial receiver connections. For use in the Piraña, only a serial receiver connection or a Spektrum Mini Port B Remote Receiver can be used. Below are a few examples of receivers that can be used with the FT Aura 5 Lite.
Aura. The cable is included with the receiver when it is purchased directly from Flex Innovations. You can also purchase the cable itself at flexinnovations.com (FPZA1039) Note: If you are using Futaba S.Bus, be sure to...
CONNECTING YOUR RECEIVER TO AURA (Auto-Detect) FT Aura 5 Lite Auto-Detect ESC THROTTLE CALIBRATION In order to map the full range of the ESC output to your throttle stick motion you will have to perform an ESC throttle calibration. NOTE: Execute ESC throttle calibration with the propeller removed. 1.
RECEIVER INSTALLATION (MOUNTING LOCATIONS) Required Tools and Fasteners #1 Phillips Screwdriver #2 Phillips Screwdriver Lift the forward hatch off of the fuselage by lifting at the front and pulling the hatch forward away from the fuselage. Remove the (4) rear hatch screws using a #2 Phillips screwdriver, and lift the rear hatch off the fuselage. Both forward and rear plywood trays can be removed with a #1 Phillips screwdriver, offering plenty of space for mounting your receiver.
WING INSTALLATION Required Tools and Fasteners #2 Phillips Screwdriver Front: (2) M3x15 Phillips head self-tapping screws (QTY 2) Rear: (2) M3.5x10 Phillips head self-tapping screws (QTY 2) 1. Locate both wings and wing tubes. Insert both wing tubes into the fuselage, noting that the short tube is installed at the front, and the long tube is installed at the rear.
VERTICAL FIN INSTALLATION Required Tools and Fasteners #2 Phillips Screwdriver (4) M3x15 Phillips head self-tapping screws (QTY 4) Locate the left and right vertical fins. Insert the vertical fin into the pocket in the main wing noting that the decals face the wing tips, and the servos orient toward the middle of the aircraft.

NOTE: The video transmitter mount is an optional accessory (FPM417010), and can be purchased at flexinnovations.com or through your local Flex Innovations dealer. Mount your video transmitter and antenna as desired. A hole is provided in the top of the fuselage for your FPV antenna. An optional video transmitter mount is available separately, and is secured to the main plywood tray using a #1 Phillips screwdriver and (2) M2 x 10 self-tapping screws that are provided with the mount.

FPV Video Gear (continued) Due to the wide variety of video cameras available, we've provided a nose that may need to be modified slightly to fit your particular camera. An easy way to mount your video camera is to simply use a couple small dots of hot glue on the front and rear of the camera to secure it in place.
BATTERY INSTALLATION Install the hook side of adhesive-backed hook and loop tape to the plywood battery tray in the fuselage, and the loop side to your battery. Place the battery on the tray, and secure it in place with the provided hook and loop strap.
CONNECTING A BATTERY TO THE LED CONTROLLER The LEDs on your aircraft are switchable via the transmitter and are designed to be powered by 12 volts (3S Li-Po) through the 6S JST-XH balance tab on the LED controller. By default, the LED controller is left unplugged from the receiver or Aura. If the servo lead of the LED controller is not plugged into the Aura or a receiver (where it is not receiving a signal), the LEDs will default in the ON position, allowing the aircraft to be flown with the LEDs on using a basic 5-channel transmitter or serial receiver with no servo port or Satellite.
The CG range is from 170mm to 185mm (6-11/16-inches to 7-9/32 inches) when measured as depicted in the image above. 174mm (6-27/32-inches) is the optimum location for all types of flying. Do not fly the Pirana with a CG further aft than 170mm (6-11/16-inches), as the aircraft can become unstable.
CONTROL DIRECTION TEST Refer to the chart below to determine the proper control surface directions. If controls are reversed, DO NOT REVERSE CONTROLS IN TRANSMITTER OR IN THE AURA CONFIG TOOL. Email us at support@flexinnovations.com for corrective action. Note that BOTH the Transmitter Control Direction Test AND the Flight Controller Sensor Direction Test MUST BOTH BE PASSED! IF ONE DOES NOT PASS, DO NOT FLY! Transmitter Proper Control...
FLIGHT CONTROL SENSING DIRECTION TEST Perform a test of the gyro system to verify the corrections made for a given movement are correct. If any of the tests do not result in the correct reaction from the airplane’s gyro system, DO NOT FLY THE AIRPLANE, and contact us via email at support@flexinnovations.com.
PRE-FLIGHT CHECKLIST and stabilize the wing with your other hand. Give the control surface a good pull away from the wing. The control surface should not come unhinged from the wing. Be sure to avoid over-stressing the part as an aggressive pull may cause the control surface to come un- hinged even though it was hinged properly.
TRIMMING The first several flights of your new Piraña should be dedicated to setup and trimming. Trimming your aircraft with the Aura is different than you would typically trim the aircraft without Aura. Transmitter trim or sub-trim will cause trim shifts when different flight modes are selected. To eliminate this trim shift, the model should be mechanically trimmed, or Aura “Quick Trim”...
- Press and HOLD both the BIND and the TRIM buttons again to exit Quick Change Mode and Restart the Aura. Your changes have now been stored. Note: Futaba users who wish to use airbrakes must visit our Wiki site for information on how to configure airbrake setup. wiki.flexinnovations.com/wiki/Pirana...
FLYING YOUR PIRANA Selecting a Flying Site Selecting a flying site is critical to a successful flight. Airplanes require a lot more room than other R/C products, therefore, a neighborhood or parking lot is less than ideal. A large open field with short grass and generous overfly area are the best candidates.
AIRCRAFT TROUBLESHOOTING GUIDE Should you encounter any abnormal situations with your Piraña, refer to the matrix below to determine the probable cause and a recommended solution for the action. If the required solution does not rectify the problem, please contact product support for further assistance. DISCREPANCY PROBABLE CAUSE RECOMMENDED SOLUTION...
AIRFRAME REPAIRS The Piraña is molded from durable EPO foam and is repairable with most adhesives. Similar to building and repairing wood or composite airplanes, the correct glue for a given application is critical to the repair holding and not breaking again. For major repairs, such as a broken fuselage, epoxy is preferred because it allows time to correct any misalignment.
SERVICING THE POWER SYSTEM Required Tools and Fasteners: #1 Phillips Screwdriver, 13mm box wrench 1. Remove the propeller from the motor. 2. Remove the front and rear hatches 3. Remove the (4) bolts holding the motor to the rewall using a #1 Phillips screwdriver. Disconnect the motor from the ESC. 4.
