The FL-R25 RCS Fuel Tank stores monopropellant for a spaceship's RCS.
Usage
The fuel tank provides fuel for all RCS thrusters of the ship. There is no need to place the thrusters directly on the tank. If there are several RCS fuel tanks the lowest will be used first to avoid jettisoning full tanks while preserving empty ones. Similarly, RCS tanks are emptied radially from the outside in. Within a stage, radial position takes precedence over vertical.
Product description
| “ | These fuel tanks monopropellant for RCS thrusters. New advances in plumbing technology made it possible to route RCS lines to any point in the ship. So unlike liquid fuel tanks, RCS Fuel tanks can be placed anywhere. | ” |
Comparison
Prior to version 0.90.0, somewhat counter-intuitively, two FL-R10 RCS Fuel Tank contained the same amount of monopropellant as a single FL-R25, yet saved 0.05 units of dry mass. The smaller tanks can also be placed radially, which made them the better choice for nearly all applications. Since v0.90.0, the FL-R25 holds slightly more than three times as much monopropellant, with similarly greater mass, edging out the equivalent in FL-R10 by 0.006 units, saving about 0.5% overall.
Changes
- Increased tech cost from 2400 to 4600
- Decreased cost from 600 to 330
- Decreased mass from 0.15 to 0.08
- Monopropellant supply decreased from 250 to 120
- Monopropellant supply increased from 100 to 250
- Capacity increased to 100, description changed.
- Retextured, capacity decreased to 25
- Due to part rebalancing, mass reduced from 0.9 to 0.5, empty mass from 0.15 to 0.1, fuel units from 250 to 200 (This does make the name slightly less meaningful)
- RCS Fuel Tanks now drain symmetrically if placed using symmetry.
