Rubber motor provides 0.8% more energy per degree centigrade temperature
(figure based on the analysis of my F1B motor tests in varying
temperatures, assuming that the average energy return from given batch
is the same, and fitting linear temperature response to the residuals),
in temperature range 16 to 25C.
