TRANSMITTER SETUP

WARNING

The FLEXF3 system is designed to work with all major transmitter and receiver brands. The FV-31 Cypher requires a 

minimum 6-channel programmable transmitter for proper function. When programming your transmitter, start with a freshly 

reset new model memory in your transmitter. 

 Make ONLY the changes shown in the Transmitter Configuration Guide 

unless otherwise noted.

The FLEXF3 in your aircraft defaults to three flight configurations that are switched via CH6 in your transmitter. In your 

transmitter, you may need to reassign CH6 to a three-position switch. 

The FLEXF3 in your aircraft also defaults to two flight profiles that are switched via CH5 in your transmitter. In your 

transmitter, you may need to reassign CH5 to a two-position switch.

Consult your transmitter manual if you have questions on how to change the switch or channel assignments.

The FLEXF3 comes pre-programmed with rates and expos specifically designed for your aircraft and its flight configurations. 

For changes in expo or dual rates, it is highly recommended to tune through the Betaflight Configurator or Speedy Bee mobile 

app.

The Betaflight Configurator is free to download, and can be used on any Windows or MacOS based PC or tablet. 

Download at:

https://github.com/betaflight/betaflight-configurator/releases

The SpeedyBee mobile application is free to download and can be used on both android and iOS devices. Simply 

search "SpeedyBee"in your device's application store.

DO NOT ATTEMPT RADIO SETUP WITH PROPELLERS INSTALLED. INADVERTENT POWER UP COULD CAUSE 

DEATH OR SERIOUS INJURY.
