Just spitballing here, lets say all us HL tankers need more range/reliability/whatever in the future. With the accumulated knowledge here I bet we could come up with a great internal system to match the great looks we are getting out of these HL's. I have been looking at converting at least 1 of my tanks to a Spektrum DX-6 or DX-7 radio, ESC, Tamiya battle system, its the defacto IR system at the moment, probably use http://pages.cthome.net/chioc/products.htm .

I guess the Elmod stuff for sound or other needed tank effects/control?

I have found this ESC that looks like it would work for a tank:
