The Rockomax "Mainsail" Liquid Engine is used to provide thrust for larger rockets and lower stages. It is typically fueled by large diameter Liquid Fuel Tanks like the Rockomax X200-32 Fuel Tank.
Usage
The Mainsail is the most common choice for lifting large stacks of liquid fuel tanks into orbit and beyond, or propelling large heavy lift vehicles. As of 0.20, this is one of three size 2 engines, and it is the highest thrust stock part. The thrust vectoring also gives it good pitch and yaw control, greatly easing first stage stability, though care must be taken to not allow Advanced S.A.S. to tear the ship apart. The high thrust of this engine, combined with thrust vectoring (TVC) can destroy poorly built rockets in the middle of ascents. Throttling down is often recommended.
The Thrust-to-Weight ratio of this engine is excellent. However, the Mainsail suffers from a rather low specific impulse, especially in a vacuum.
The Mainsail also tends to quickly explode from overheating when run on maximum throttle, especially when placed under a Rockomax Jumbo 64 Fuel Tank, where it will overheat within 5-15 seconds of maximum thrust, so be careful not to max out a Mainsail unless low on fuel. Overheat-safe throttle levels are about 60 % when mounted under the Jumbo-64, and about 80 % otherwise.

Changes
- Overheats much faster
- (Undocumented) Renamed, thrust increased (1200 -> 1500), weight decreased (7 -> 6), new description
- Initial Release
