Hi TeckP
First up see below for the RC2HL setup...

Although the Tamiya Template should work you should also have had as an option a specific RC2HL template. The Tamiya template only allows for turning the tank on using the left stick. The RC2HL template has the Engine ON/OFF, magine gun and Cannon all assigned to switches. Have you watched the video on the RCTA youtube channel on how to apply templates correctly? It is a bit tricky.
I assume that you have been trying to turn the tank on by moving the left stick to the bottom right. The tank should turn on when you see the display like below

Lots of how to videos with the RC2HL, Turnigy (X and the HKT6A receiver on our youtube channel
