On long trading hauls (like rares where you're making 150+ ly "legs"), it could save you the time it takes to supercruise to a station and refuel partway through the journey. Docking for fuel is the slowest part of a long haul; jumping from star to star is actually fairly quick.
Which you don't have to do since it refills itself from the main tank. There's no need to buy fuel, ever, basically, once you get a decent fuel scoop.
i have a cobra and need to find where the A2 scoops are sold and A4 thrusters and frame drives ;(
IIRC, I bought my A4 frame drive at the outpost with a high tech economy in Delta Phoenicis. I don't think they had A4 thrusters or A2 scoops, though.
Finally managed to buy a cobra after a lot of saving. It's a thirsty beast. Fitted a fuel scoop to try and save some money.
Scooping at my local sun. Managed to get the rate up to 20 and then just sat there. And sat there.. The fuel gauge hardly moved.
In fact it's so slow I estimated that I could dock, and do another cargo run and make a shed load more money than the fuel would cost in less time than it would take to scoop.
So, am I using it wrong? Or is a full scoop on a larger ship a waste of space?
