Thanks for the help jraskell and TiboJ!
I was able to control WT and the PT using the radio. This will allow me to fine tune the WT platform.
Now my application will require the WT to operate in a very thick steel wall vessel about 100 feet away from the operator so to solve the radio wave penatration and multipath issues, I will have to go wired vs. wireless. Let me know if you have any insight in eliminating the radio receiver and connecting directly to the WT Controller with a cable.
BTW, I will keep you up to date with my project too!
