We on team 343 are using a heavy duty bungie as a counter balance on our lifting mechanism. You can see pictures on our site,
www.metalinmotion.com. The bungies are tucked into the diagonal supports (they're white with blue stripes). They keep the current draw on the fisher price motors down around 10 Amps. For a closer look come by our pit at Florida, Palmetto or the Championship.
Have a great Season!!
