Simple control/tether?

[greenkarson]

Here is the first of many questions to come. Im planing (hoping) to dive around 500" to 550". So im going with on board 12v batteries. Probley a lawnmower battery(s) to run the motors and head light(50watt). So can i just use simple 12v relays and 500-600" of phone wire with momentary switches to activate the motors?
Thanks karson
