Hi Mike and welcome to the collectors corner. You will soon realise that 1 or 2 simply does not suffice. I'm in your boat....being a modeller and enjoy RC tanks but don't do anything but the very bare essetials of anything electronic. I do the tank conversions and detailing and let Blitz do the hookups. Phil "Blitz" does all my electronic hookups and he does really fine work. I put out some $$ on the El Mod on my M-46, but that is a special tank and warranted the finacial outlay. Phil and his buddy Merle installed the El mod and it's a terrific setup. I know Phil gets work from all over and believe he has a couple from UK. You may want to contact him if you don't find someone local in the UK.
