You have to know your ship and what star you are scooping. What is fine around an M with all your modules off, is not fine around a big old O with your shields on.You start charging the frameshift drive while the fuel scoop is still engaged? I just saw the heat go up massively and assumed that I would start taking damage. At least that has happened to me in the past and I haven't tried it since. I suppose I could give it a try now that I am back at the bubble. I also plan to test my heat sinks again just to find out exactly how responsive they are to key presses.
It's been useful to find out though that you can still fuel scoop at max rate even when the throttle is at zero once you are up to maximum rate. I might find a use for that if I need to fill an empty tank or the orbit line isn't showing.
