This little vehicle can effortlessly reach Minmus, all while running on a single tank of fuel. Once there, it can easily refuel and then venture pretty much anywhere in the system. After a complete refuel, this spacecraft has approximately 4600 delta-V to spare, with no cargo or payload on board. The design shown includes a satellite that will be placed into orbit around Tylo, which resulted in about 4150 delta-V remaining after refueling. It's essential to note that when taking off from Kerbin, the tanks should not be completely full - this causes excessive weight and instability. A good takeoff strategy is to fill them about halfway, achieving a more balanced and stable flight.
