The FL-T800 Fuel Tank is a liquid fuel tank containing liquid fuel and oxidizer.

It is the largest tank in the 1.25m FL-T series, twice the size of the FL-T400 Fuel Tank. It contains the same amount of fuel as the smallest tank in the Rockomax X200 series, the Rockomax X200-8 Fuel Tank.

Product description

A stretched variant of the FL-T400, the FL-T800 holds twice the fuel in a slightly stronger container. The black stripes along the side make the rocket go faster, our engineers tell us.

The FL-T800 Fuel Tank is a liquid fuel tank containing LF/O mix. This allows it to power liquid fuel rocket engines, like the LV-909 "Terrier" Liquid Fuel Engine. If there are multiple liquid fuel tanks connected to an engine, then they will all be drained equally to power it. [1] The FL-T800 can be placed both in-line and radially mounted.

When full, one tank can power a single LV-909 "Terrier" Liquid Fuel Engine for up to 225.6 seconds at full thrust, or a single LV-T30 "Reliant" Liquid Fuel Engine for up to 50.7 seconds at full thrust.

The FL-T800 fits well on main stages, providing a large amount of fuel.


As of version 1.5 this fuel tank has four textures that can be switched in the editor.
