Diametric Drive

The diametric drive is a very powerful, fast and robust form of cruising propulsion.

Overview
Developed on Centura this is now the federation's most common form of cruising propulsion. It terms of speed this even beats the Photon Drive developed by the Hackabots. Despite this the Photon Drive requires less power and can be ran for longer periods of time. Nearly all of Legolands space crafts have this drive installed. It relies just on energy which is a big advantage.

Users
Humans - 90% of human and legoland ships use this method of propulsion for cruising.

The Droid Alliance - A similar device that works on the same principle is used by the droids. Generally speaking Legolands Diametric Drive is more advanced but the droids warp capabilities are more advanced than Legolands warp drives.

Trivia

 * This is based of a real form of experimental propulsion; see here.
 * Uses a gravity field to propel the craft

Current Status
This technology still remains a very powerful form of cruising propulsion. Legolands drive is still considerably better than the droids version.
