1st ch. you mean trottle ? It always has rate faster than analog, every ESC drom China thatI tried works at fast refresh rate.

There is no full description of setup codes used w/Ulink so I'll post most used codes here:

1st you have to set starting frequency of nunchuck and RX
enter 6 digits into RX and same into Nunchuck after clicking "C" 6 times.:
U-Link RX, setting RF channel (1 min 1 sec)

Then set sub-channels on both, RX use codes 1.x and nunchuck as all setup codes the same but starting with 6, that is 6.1.x

Sub-channels are pre-defined groups of frequencies so RX can track multiple transmitters (repeaters and nunchucks) when flying in multimaster mode or when you fly and someone else control your P/T

The RX has beacon function, to enter new frequenc y enter 6digits same as RX frequency set but substituteleading "4" with "1" , if entered 162622 actual frequency stored will be 462.822MHz (CH5 FRS)

single digits codes:
1 click - calibrate gyros (never used, it's easier to push elevator stick while holding Z-btn on nunchuck
2 clicks - reverse both servos(only works if active flying wing mix)
3clicks -reverse pan direction
4clicks - reverse tilt direction
5clicks activates video switcher( if installed) or switches between cormal pan servo and continuoes totation servo

group 2.x used to set gyro gain (normally not needed)

group 3.x used to reverse gyros:
3.1 X gyro reverse
3.2 Y :reverse
3.3 Yaw gyro revers
3.4 swap X and Y axis ( same effect as if rotate RX board 90degree), thus the board can be installed in 8 positions (4 with 90deg. pitch face up and 4 upside down)

4.1 and 4,2 flying wing mixes , 4.3 classic mix, 4.4 - base installation for camera or antenna P/T (not flying mode)

5.x AUX B modes:
5.1 fireworks igniter - connect nichrome wire to high current FET (oboard)
5.2 random LED lights (same FET used to control power LEDs)
5.3 PPM input, incoming PPM is master -overtakes control if 1st 2 channels not centered(1.5ms)
5.4 the same but control signal is ch5
5.5 Power LEDs strobe - double blink every 1.5s

6.X Aux-A codes:
6.1 Fireworks igniter 2nd channel
6.2 3-position switch (PWM 1ms,1.5ms,2ms)
6.3 Rudder PWM out
6.4 PPM out
6.5 LEDs blinks fast

7.x frequency hopping step (0-2MHz)

8. servo reverse, for mixes 4.3 and up:
8.1 reverse Aileron
8.2 reverse Elevator
8.3 rudder

9.1 digital servos 9.2 analog

Beacon starts to transmit only if motor was active atleast 1s,, when you connect power to RX buzzer and beacon won't activate till 1st failsave then timed 2minutes on old receivers and 50seconds on new.
