Matek H743-slim FC and an ELRS receiver - no signal in MP

I am using a matek h743-slim fc and an elrs receiver which is binded to a Taranis Q X7 using a radiomaster ranger micro module for a drone
but I am not getting any stick input in mission planer
these are the params I have changed

# Arming with Rudder enable/disable
# Allow arm/disarm by rudder input. When enabled arming can be done with right rudder, disarming with
# left rudder. Rudder arming only works with throttle at zero +- deadzone (RCx_DZ). Depending on
# vehicle type, arming in certain modes is prevented. See the wiki for each vehicle. Caution is
# recommended when arming if it is allowed in an auto-throttle mode!
# 0: Disabled
# 1: ArmingOnly
# 2: ArmOrDisarm
ARMING_RUDDER,0  # We find it safer to use only a switch to arm instead of through rudder inputs

# Alternative HW config
# Select an alternative hardware configuration. A value of zero selects the default configuration for
# this board. Other values are board specific. Please see the documentation for your board for details
# on any alternative configuration values that may be available.

Try editing that and using it. Your parameters do look OK. So check the wiring.

For ELRS you also need
RC_OPTIONS = 8224
It is documented here and was discussed here, here and hinted here.
