Looking for a description of low efficiency in Rubber band or Tubing I am looking for a description of power loss in that you dont get out the work you put into pulling latex tubing. I have some new latex tubing that is treated with UV protection and is super hard to pull from the very start yet yields no higher launch of my radio controlled glider than another brand. I am trying to explain this wasted energy in pulling it back in energy storage loss. I need words or a paragraph that describe how bad this is other than words "energy storage" that will explain how this brand is not as good as the previous one. Its more pull to pull it back than it delivers?
