Recently updated with new VASIMR engine models and better functionality. 

This pack contains electrostatic ion engines, plasma engines and VASIMR engines. There are currently 14 types of varying size and thrust. The function of the engines is quite simple - power them, provide the correct fuel and then profit. The two VASIMR engines however need more explaining; they start out at their lowest thrust and highest specific impulse. Use the slider in the VAB or in flight to increase thrust at the cost of specific impulse.

The engines run on stock Xenon Gas and two new resources: Lithium and Argon Gas. Make sure to have enough power to run them, as shown in the VAB. Also, don't run them in atmosphere - they'll produce practically no thrust. Good luck powering many of the engines on stock parts though - they're quite power-hungry. I recommend large solar panels from Near Future Solar or nuclear reactors from Near Future Electrical.
