My team is doing an elevator system that is run with chain. Our system is run by two
Andymark 9015 motors and a 1:35 planetary from vex. These are the stats for the system are here.
With what we have so far it seems to work fine, but if the 9015 motors are not strong enough we are going to switch to the bane bots
RS-775-18 motors. Here are the stats for the RS-775-18 motors.
My best advice would be to use the
dual input attachment for the
vex pro planetary gearbox. They are very easy to work with.
Best of luck!
PS. If you do use the 9015 motors, you have to cut the output shafts down a little for it to work with the dual input.
