James you can't do that ... the new tiger I controller and ESC in my opinion works just as good maybe better than the HL S&S system... It's just that only the latest tanks they will use the tiger I electrics in but also keep the tiger I sound for all the new tanks wich is stupid on VS's part....I put HL S&S radio and electrics in my 1/24 abrams and Leo A5 they drive like a chrm now!
