to try the WK2801 protocol 1
st
when working with older Walkera models before
attempting the WK2601 or WK2401 mode, as the WK2801 is a superior protocol. The
WK2801 protocol supports up to 8 channels, and both auto-binding and manual-binding.
If FixedID is set to ‘None’ the transmitter will attempt to auto-bind with the receiver
every time it is powered on. If a value is set for FixedID, the receiver must be bound
manually one-time using the ‘Bind’ button, after which it should stay bound.
Protocol: WK2601
The WK2601 protocol is used to control older Walkera models. The previous Walkera
models were segmented into 3 similar but not identical protocols: WK2801, WK2601,
WK2401. This roughly corresponds to the number of channels supported, but many of
the newer 6-channel receivers actually support the WK2801 protocol. It is recommended
to try the WK2801 protocol 1

when working with older Walkera models before
attempting the WK2601 or WK2401 mode, as the WK2801 is a superior protocol. The
WK2601 protocol supports up to 7 channels, and only supports auto-binding. The fixed
ID can be used, but does not prevent auto-binding during power-on.
The WK2601 protocol also supports additional options. These are accessed by pressing
the Protocol spin-box when Wk2601 is shown:
Chan mode: Sets how channels are processed:
• 5+1: AIL, ELE, THR, RUD, GYRO (ch 7) are proportional. Gear (ch 5) is
binary. Ch 6 is disabled
• Heli: AIL, ELE, THR, RUD, GYRO are proportional. Gear (ch 5) is binary. COL
(ch 6) is linked to Thr. If Ch6 >= 0, the Rx will apply a 3D curve to the Thr. If
Ch6 < 0, the Rx will apply normal curves to the Thr. The value of Ch6 defines
the ratio of COL to THR.
• 6+1: AIL, ELE, THR, RUD, COL (ch 6), GYRO (ch 7) are proportional. Gear
(ch 5) is binary. This mode is highly experimental.
COL Inv: Invert COL servo
COL Limit: Set maximum range of COL servo
Protocol: WK2401
The WK2401 protocol is used to control older Walkera models. The previous Walkera
models were segmented into 3 similar but not identical protocols: WK2801, WK2601,
WK2401. This roughly corresponds to the number of channels supported, but many of

WK2401 protocol supports up to 4 channels, and only supports auto-binding. The fixed
ID can be used, but does not prevent auto-binding during power-on.
Protocol: DSM2
The DSM2 protocol is used to control many Spektrum™ and JR™, as well as other
models using this protocol. While the DSM2 protocol can support up to 14 channels,
Deviation is currently limited to a maximum of 12. Note that many receivers with less
than 8 channels require the Transmitter to send 7 or less channels. Make sure the # of
channels is set appropriately for the receiver. DSM2 does not support auto-binding.
