1. INTRODUCTION
BETAFPV Lite 2S FC is a brushless flight controller with Silverware firmware. It is with
build-in Frsky D8 receiver, and it also supports external receiver with SBUS protocol and
DSMX protocol. For fans of Silverware firmware, now you could try it with brushless drone
like Beta85 Pro 2. The stock firmware is based on brushed NFE_Silverware, which is
used on popular ZER0 board. With an ingenious design of build-in OSD, it’s convenient
for users to observe the flying status and change the configuration like PID.
2. SPECIFICATION

4. BASIC FUNCTION
• Supports brushless drone up to 2S battery power
• Includes the OSD menu. Supports PID tuning, motor rotation, vtx frequency changing
and channel mapping checking via OSD menu
• Build-in receiver with Frsky D8 protocol and support for external receiver with SBUS
protocol or DSMX protocol
• Supports various flying mode: Acromode / Levelmode / Racemode_Angle /
Racemode_Horizon / Horizonmode
• Supports Turtle mode, easy to turn the drone over when the quad is inverted
5. RECEIVER CONNECTION AND BINDING METHOD
The FC integrates with Frsky D8 receiver, and also supports external receivers both
SBUS and DSMX protocol. Users could switch receiver communication protocol directly
via FC button.The status is indicated with 3 LED flashes. Receiver communication
protocol will be saved automatically when you power off, it will keep the same when you
power up again.
For more details, kindly check the picture below.

5. 1 Frsky D8 Receiver
Lite 2S brushless FC is with build-in frsky D8 receiver. The communication protocol should
be set as INT_SBUS protocol when using frsky D8 receiver, as follows:
• Press the FC button on the bottom of the FC and plug the battery at the same time
• Release the FC button after 4 seconds
• Once “INT_SBUS ” shown, FC is successfully changed to INT_SBUS mode
How to bind:
Note: Please ensure that the the receiver communication protocol is in INT_SBUS
protocol.
• Press receiver button on the bottom of the FC and plug battery at the same time till
green LED is solid.
• Choose “bind” option in the transmitter, bind is successful when green led flashes.
• Power up again, if the data is successfully received, the green led will be solid.
5. 2 SBUS Protocol
Supports SBUS protocol, including Frsky xm / xm+ receiver, Futaba receiver. Here is the
diagram with SBUS protocol:
The communication protocol should be set as SBUS protocol when using the SBUS
protocol, as follows:
• Press the FC button on the bottom of the FC and plug the battery at the same time
• Release the button and press the FC button again within 4 seconds
• Once “SBUS”shown, FC is successfully changed to SBUS mode.
5. 3 DSMX Protocol
Supports DSMX protocol. Here is the diagram with DSMX protocol:
The communication protocol should be set as DSMX protocol when using DSMX receiver,
as follows:
• Press the FC button on the bottom of the FC and plug the battery at the same time
• Release the button and press the FC button TWICE within 4 seconds
• Once “DSMX”shown, FC is successfully changed to DSMX mode.
6. OSD MENU
AETR is the default channel mapping of Lite 2S Brushless.
Eight options on OSD Menu: PID, MOTO, RECEIVER, SMARTAUDIO, DISPLAY, RATES,
SAVE and BACK. When you choose PID, cursor will show on PID option.
Supports PID tuning, motor spinning direction changing, channel mapping checking,
frequency and vtx power changing via OSD menu. The operation of OSD Menu on Lite 2S
Brushless FC is same as Betaflight.
6.1 How to Enter OSD Menu
The method of entering OSD Menu on Lite 2S Brushless FC is same as Betaflight, Make
sure the drone is disarmed when entering OSD Menu on Lite 2S Brushless FC.
-Use Mode 2 (American Mode) as example-
Note: AETR is the default channel mapping of Lite 2S . If you can not enter the OSD
menu, it might cause by unmatched channel mapping.
6.2 How to Operate OSD Menu
By moving the cursor, you can enter sub-menu of PID, MOTO, RECEIVER and
SMARTSUDIO to change the related parameters.
If the parameters are changed, you can choose the SAVE option, and then select BACK to
return, so that they will be saved and take effect.
-Use Mode 2 (American Mode) as example-
6. 3 How to Tune PID
Here is the method of PID tuning
• Enter OSD menu
• Move the cursor to PID option and enter PID sub-menu, the PID for ROLL, PITCH and
YAW is available for tuning.
• If you want to change the PID parameters, please choose the EXIT option to exit from
PID sub-menu, then back to the OSD menu to select SAVE option, so that the parameters
you changed will be saved and take effect.
-PID menu interface-
-Use Mode two (American Mode) as example-
6.4 How to Change Motor Rotation
Here is the method of Motor rotation Changing
• Enter OSD menu.
• Move the cursor to MOTO option and enter MOTO sub-menu. M1, M2, M3 and M4
represent four motors on the drone. N represents normal, which means counter -
clockwise rotation, R represents reversed, which means clockwise rotation
