The 24-77 "Twitch" Liquid Fuel Engine is used to provide thrust to a rocket. It is great for small probe landers because it has a great thrust-to-weight ratio. While it can be radially attached without a structural part and can be used to fit landing legs, it has the downside of being less powerful and efficient than the 48-7S "Spark" Liquid Fuel Engine but is 10 kg lighter.

Product description

Tiny engine! But very useful, good for craft where larger radial engines won't fit, or when you want more control in combination with large lifter engines.


  • Cost increased from 240 to 480 (and made meaningful)
  • Initial Release
