kindred cave
works pretty well, usually about 15 to 20 blocks precison(i could bring that down to essentially 0 by adding "steering" during terminal but I'm tired)
can start basically from anywhere even from underwater lol
don't mind the explosion i just built a really inefficent payload it seems
sadly not really practical since usually you don't have such a high ship load distance and with a player(and I assume chunkloader would cause the same) in it it just does silly stuff because of loading chunks
haven't messured the range yet because as said it's really hard tohave it fly further than your ship load distance but it has enough fuel to run the thrusters for 6 minutes straight so about 3600 blocks of theoretical range i guess
sorry for the long yap but i don't think anybody fully reads that anyway lol
