Hi ADP
I can only help you with your RC5HL, I can offer no help or advice re: the Clark board.
What you have done is very common - you will have missed a few of the important steps on setting up your 9X
1. GO to RADIO Setup
Change channel order to RTEA
Change MODE to mode 3
Calibrate your radio
2. GO to you model setup
go to templates menu and clear all mixes
go to the RC5HL template and apply it.
Move to the receiver and RC5HL
Connect CH 1 of receiver to IN1 on RC5HL
VERY IMPORTANT
Connect CH 2 of receiver to IN3 on RC5HL
Connect CH 3 of receiver to IN2 on RC5HL
Connect CH 4 of receiver to IN4 on RC5HL
Connect CH 5 of receiver to IN5 on RC5HL
move receiver jumper to across the top 2 pins (position for Turnigy receiver)
To start up
Turn radio on - make sure that CH1 to CH5 are ALL AT NEUTRAL
3pos ID switch must be in MIDDLE position
Turn on tank -WAIT for green LED on RC5HL to go solid on
Push 3 Pos switch up and back to middle
All should be good
There are many many many videos of this setup on the RCTA youtube channel
www.youtube.com/rctanksauNOTE the 9XR and 9X are identical radios
Your Clark problems will be solved by understanding your 9X a bit better and I think once you follow the RADIO setup procedure outline above things will be different.
Finally the templates are for various tank controller units. Only the Turnigy 8 Channel and Hobby King 6 and 3 channel receivers will bind to the stock 9X. There are no later versions of tankER9X beyond Anzio. All firmwares are good and are not the issue here.
Cheers
