Get to the north pole - top number (latitude) on your hud should be 90 (-90 for south pole), the second number does not matter to get there. Just turn your ship to bearing 0 and fly (normal, sc, glide, does not matter) till you get to 90 - you are at the north pole.
Then pick up any number you like on the lower display (thats longitude -180 to 180) , this is the one you will be searching along and you need to stick to it, turn your ship towards south pole (bearing 180 in the middle top of your hud) and just go. Make sure your bearing is 180 and the bottom number is what you selected (so let say you picked up longitude -57, on the bottom part it should say -57, if you move away from it to check something, then just come back)
Bum! after 6 hours you arrived at the south pole (top number -90) , then pick up another longitude ie.135 , turn your ship to bearing 0 and you go for the north pole along 135 - another 6 hours
This is how I did find Delta site anyway![]()
I totally understand your logic when dealing with small planets, i wish this lump of space rock was also 550km radius, then 6 hours would seem a walk in the park. it however is 7 times bigger and those 6 hours are more like a day and a bit just to go one from north to south specially when your top speed is 160 m/s
