If ALTA Pro is purchased as a bundle with a transmitter or FPV kit, these will be factory installed and ALTA Pro will be ready to fly out of the box! For customers installing their own receivers or FPV systems, please follow the instructions below. The guide details the first time setup process for ALTA Pro 8.
Radio Controller Receiver
ALTA Pro requires the installation of a radio control system. S.Bus, S.Bus2, DSM2, and DSMX receiver types are supported. Some ALTA Pro emergency control modes (Return-to-Land and Autoland) may vary depending on the type of radio. Refer to the Flight Controller Modes section of this manual for additional details.
Additionally, ALTA Pro supports radio receiver diversity using S.Bus, S.Bus2, DSM2 and DSMX receivers. This means two receivers may be installed, and the Autopilot flight controller will automatically use the receiver with the best signal quality. Using two receivers requires the radio controller to be bound to both receivers. Refer to the instructions provided with your radio controller to complete the binding process. For Spektrum radios a receiver is required to bind the satellites to a radio controller.
Locate the noted closeout panels used for receiver installation (between booms 2 & 3 and 6 & 7).
2. Remove side closeout panel with radio wires using a 2.0mm hex driver.
3. Plug signal wire into receiver.
4. If using telemetry, plug the telemetry wire located in the closeout between booms 2 & 3 into the primary receiver (refer to the Voltage Telemetry section).
5. Feed receiver antenna into lower antenna tube.
6. Secure receiver using the provided double-sided tape to inside of receiver housing.
7. Reattach closeout panel.
8. Route antenna wires into the two antenna tubes below ALTA Pro chassis.
9. Repeat installation process for dual receivers (if applicable).
Locate the noted closeout panels used for Spektrum receiver installation (between booms 3 & 4 and 7 & 8).
2. Remove side closeout panel using a 2.0mm hex driver.
3. Feed signal cable through panel grommet.
4. Reattach closeout panel.
5. Plug in receiver/satellite into signal cable.
6. Attach receiver/satellite to exterior using double-sided tape.
7. Repeat steps 1-6 for dual receivers (if applicable).
ALTA Pro supports battery voltage telemetry on Futaba radios when using a receiver that supports an external voltage sensor, such as the R7008SB. Installing the telemetry wire is easiest when initially installing the receiver. To set up ALTA Pro with voltage telemetry for Futaba radios:
Installing Voltage Telemetry for ALTA Pro 8
Remove the closeout panel between booms 2 and 3 with a 2.0mm hex driver and locate the radio receiver wire bundle.
2. Identify the voltage sense wire and connector in the bundle. It is the small, 2-pin connector attached to a black and red wire pair.
This wire is already connected to an in-line fuse. Soldering a fuse into this wire is not required.
3. Connect the cable to the voltage sense port on the primary Futaba receiver.
4. Reattach the closeout panel.
ALTA Pro can power a variety of first person view (FPV) cameras and transmitters, as well as add informational on-screen display (OSD) elements to aid in FPV flying. Using an FPV ground station display can be a useful method of monitoring status, performance, and flight parameters of the ALTA Pro during flight.
Three FPV transmitter cables are included with each ALTA Pro. Each supplied cable has one side with a connector that mates with a cable located in the closeout panel between booms 1 & 2. The other end of each supplied cable has specialty connector(s) to run Immersion RC, Fatshark, BOSCAM, or BOSCAM compact FPV transmitters. For cable identification, refer to the FPV Transmitter installation instructions.
A single camera cable is provided and is configured to run a Ready Made RC camera (model RMRC-700XVN recommended). This cable mates with a pre-installed cable located behind the closeout panel between booms 1 & 8.
Camera and transmitter cables follow this wiring scheme:

It is the responsibility of the pilot to see and avoid other aircraft, people, or obstacles. Always maintain direct line of sight with ALTA Pro during flight, use visual observers as operations require, and follow local regulations regarding see-and-avoid requirements.
Do not short the pins of the FPV transmitter connector located on the pre-installed FPV transmitter lead in the ALTA Pro. Doing so could damage the on-screen display circuit. If using a multimeter to check the pins, first connect one of the provided transmitter cables, then take voltage readings from the transmitter cable.
FPV Camera ALTA Pro 8 Remove the front closeout panel with a 2.0mm hex driver.
2. Locate the FPV camera cable included in the ALTA Pro package.
3. Pass the FPV cable through the closeout panel grommet and connect to the mating FPV camera lead inside ALTA Pro. Connect the other end directly to the camera.
4. Replace front closeout panel.
5. Mount FPV camera on the FPV mount on the front ALTA Pro using the provided hardware.
Mount FPV transmitter on the provided carbon fiber accessory mount plate
Attach accessory mount to boom 2 with M3x6 flathead bolts.
3. Locate the appropriate FPV transmitter cable. The following cables are included:
a. ImmersionRC/Fat Shark (cable with two connectors)
b. BOSCAM/SkyZone (cable with one large connector)
c. Compact BOSCAM (cable with one small connector)
4. Use a pair of dykes to cut the zip tie holding the braided transmitter cable to the corrugated tube on boom 2
5. Pass transmitter cable through the underside of the hinge, connect to the correct FPV transmitter cable, and plug into the FPV transmitter.
6. Zip tie the FPV transmitter lead to the boom 1 cable bundle and the FPV Transmitter mount for strain relief. The boom should be fully folded when the transmitter lead is zip-tied to cable bundle.
A number of properties and components can be adjusted or added to the FPV On Screen Display (OSD) using QGroundControl. To access these settings go to the the ALTA settings group in the Parameters tab of the Vehicle Setup menu.
