A complete overhaul of the VX series engine pack.

While VX Series II is essentially an entirely new set of engines, it is still compatible with saves using the original VX series engines. Some engine roles have been changed however, with the "Impulse" and "Big Impulse" engines most effected by these changes. I would advise not installing if you have missions in progress with these engines.

Please delete any version of the original VX series pack you may have installed before installing the Series II engine pack.

Version 1.0.2 for Kerbal Space Program 1.1.3

Released on 2016-07-04


  • The Omicron and Sigma engines have been modified so that thrust is being generated from the Monopropellant nozzles while in Monopropellant mode. Previously thrust was being generated from the location of the main nozzle in either mode. This was an oversight.
  • The "Impulse" and "Big Impulse" have been added as optional Legacy parts. The entire original VX series is still available for download, though it is no longer supported and will not be receiving updates. By adding these parts to this pack, I will continue to support them.
