As mentioned in other topics I did not notice a thing of the runtime but probably I do not search the limit that tight but dit notice a better consistent tuning so the theory of finding a better limt with a lower consumption is there.
The datalogger on the heli in the link I showed did show a lower and more consistent temperature with a cooler of the fuel and also my telemetry did show a temperature of 40 degrees in the tank without a cooler.
Also take a look to some specs of oil. between 30 and 40 C there is already a difference in the viscocity.
You can tell what you want but the numbers and a lot of experiences do not lie. But yes, it is adding weight and longer fuellines, as if you buggy drivers do use short lines...
