This Mod provide 3 system to imitate the function of them.

1, Engine

All 3 varieties could work like an engine, provide acceleration(Based on Max Overload) towards forward direction of control part (regardless of installed position).

2, Advanced speed control

All drives could provide 3 axis velocity control(Based on Max Overload).

3,GN particle generator

GN drive could generate GN particle at no cost.

While GN drive-Tau and GN CondenserFrame need some ElectricCharge to activate the generator.

GN drive

Consider as the most powerful production of Celestial Being.

Even it is asexpensive as a Duna station, it worth a try.

GN drive-Tau

Tau engine can not generate GNparticle itself, it has to convert ElectricCharge to GNparticle, so far, the rate is 1:1 and generate speed is 800 unit/s.

And if Tau engine "GNpartical depleted", it will stay this status until GNparticle refill.

GN Condenser Drive

Condenser drive is a non-perpetual interplanetary drive at early stage .

It couldn't generate GNpartical and its fuel efficiency is lower than other drives.

GN Condenser Frame

Condenser Frame is the solution for Early stage infinite fuel. It holds a limit amount particle and could generate 180 unit particle at the cost of 200 ElectricCharge
