Do you prefer to use CM motors, or Stagemakers? I've heard quite a few for either way. Stage makers are a bit quiet. CM's are easier to work on in the field. CM offers training to work on their motors, Stagemakers don't.
Your thoughts...
I work with both, but have more experience with CM. However, I prefer stagemaker. The stage makers are quieter, have a lighter chain and have a sweet self limiting feature should it run out the chain in either direction. A recent batch of brand new CMs ended up with half of them being defective in a couple months, but CM took them back and fixed them under warranty and theve been fine ever since. I do know some riggers don't like the lighter chain on the stagemakers as sometimes the chain won't have enough weight to set a point. Either way, your gear will be lifted safely and reliably , which is the important part.
