Tam 3329 NEEDS YOUR HELP!

[HarveyAce]

We are using window motors to articulate our arm, and we have a complication with the system. The arm goes in an almost full 360 degree motion, but with the gripper on the end, we cant get it to lift more than horizontal on either direction. it seems that we need a tension system to act as a counterbalance for the joint. would it be possible to use bungee cords? do they provide enough tension to help counteract some of the weight? we need this fixed today because tomorow is the ship day! this isnt good at all. the rest of the bot works great. ill post a pic on the portal of what we got. its team 3329. thanks!
