Power core #7 with Pipe #4 would be the best combination in my opinion.
@devs, @james: maye you can answer some questions i already asked in the power core topic (where i don’t got any anwers)
this question is done … we use pipes right ? can they be used for long distances ?
last but not least … before i can vote for engines i like to know what the do ?! … are they for the workbanches ? or do they work indivually ?
