Maximum Altitude, Maximum Mass, 50% Payload Graphs.

[Dispatcher]

The two graphs are based on Kerbin flight tests of all stock engines, including those released with the ARM update. They show the maximum lifted mass and altitude, wherein half the mass is payload (that is, not used as fuel during the flight). The first includes the RAPIER (air mode) and the second excludes it in order to "zoom in" on the remaining results, but the average is retained. No altitude results are shown for SRBs as their fuel units are at a fixed maximum. However, the maximum mass the SRBs can lift is shown. There are two aero spike results; the best result for it is with parts possessing its same diameter rather than wider fuel tanks. Mass is in metric tons, altitude is in kilometers.
