Finally got some pics so I can start to build my rotator wrecker (in my free time ) building it no prob just take some time for all the detail . mechanical/electrical no prob. now here is the run down for channels
truck drive and under lift function 6 channels
1 fwd/rev
2 steer
3 shift
4 under lift flip down
5 under lift extend
6 under lift up down
rotator function 10 channels
out riggers
1 extend
2 down
boom
3 up/down
4 swing
5 boom in/out
6/7 boom winches
8-10 bed winches maybe (would like too)

now I know there is away to add channels . who,where ,do i get the parts ? and is it legal to do this my self ? I was thinking of getting a airtronics sd-10 If there is a better alternative ,I'm all ears (well eyes )

thanks for any input
