Torque chart for Super Sport model airplane rubber in 1/8″ size. This is my conservative starting point for rubber motors in various sizes that I use when flying. While different batches of rubber can yield far different results, this chart does give you a good starting point and basic information on what super sport rubber can take. I find that I often exceed these limits but prefer to wind to approximately 75% of maximum torque and get two flights out of the rubber motor if at all possible. In heated competition, this is not always possible and you find yourself pushing the winding to the limits. It is always a good idea to test your own batches of rubber so you can come to your own conclusions on the quality rubber you have.
