Hello Skip2a I am actually the Clark board vendor here in the United States you can view my website at RC TANKS OF OKC - Home - oklahoma city, OK Clark Models has just recently asked me to help him out with new instructions on the Clark boards and there products I felt the simpliest way to help is to start making videos of the installation of the products and posting my support number for customers to call which is on my website and has been since day one contrary to other tank builders claiming to be the only one with a phone number listed on there site "Bob", my number is 405-476-2244. Feel free to contact me and if I do not answer just leave a message and I will contact you as I so have a day job. For any others out there keep a lookout for my face book page "rctanksofokc" for the videos. Thanks and happy Tanking
