Normal Quality. About 100km/s. Mainly runs on solar. If you have any quality solar you might be able to replace the reactor completely.
Also you could extend the cargo bays.
Manually place some Fuel in the reactor to get it up to temp at the beggining. Makes calcite, adjust the inserters depending on how much you want the cargo hold to accept. Can also be used to transport other items since it's flying around anyway.
