Thanks for all the information Guys-We are actually running 24 volt CIM wheelchair
motors, the power is via 2 lipo 4s which gives us 32 volts.
I dont really want to change that set up because we are really happy with the
performance so far.
The motor for the jaws I think is also a CIM but a slightly longer one than the
ones used for the drive-it's rated at 30 amp also.
The idea is that one member of the team will have a two button box coming
off the main radio controller for open and close of jaws, I'm thinking the buttons will
be on springs so a quick press on either closes the jaws ( in tests the jaws closed
in less than a second on 16 volts) Im not sure how much amps will be drawn when
the jaws meet thier stop point.-theres no provision to cut the power supply at present.
Also is there a preffered method to get 32 volts down to 24 as most ESC I have
seen have a top voltage of 24 volts.
