Once the crewed version had entered serial production, there were no more development funds to embezzle. The solution came from feedback provided by the industry; specifically what do you mean I can’t take my stuff and can it carry a satellite.

Setting to work, the development engineer made a revolutionary discovery: the equipment needed to keep the crew’s insides from rapidly becoming their outsides was heavy and expensive. Consequently, the cargo variant can carry nearly anything that will fit inside and inject it into a higher orbit. Unfortunately, the development cycle was very rapid, once again putting IslaDyn in the uncomfortable position of legitimate business.


Heavy payloads may require removing some oxidizer to achieve 500m/s at the surface. This will limit Delta-V in orbit, but will buy you more payload.

Take off from a runway, rotating at 80 m/s. Fly low, gaining speed just above the surface of the water until you reach 500m/s, then gently pull into a 15 deg. climb. Emphasis on gently, as dropping below 450m/s will mean the RAPIER will not be able to accelerate the craft during the climb.

Go hands off, relying only on SAS to maintain the climb, then select Prograde once the RAPIER automatically switches to Closed Cycle. Burn until your Apoapsis reaches the mid 70’s. Circularize at Apoapsis.

Reenter using the RAPIER. Use Action Group 1 to toggle into the reentry configuration, and use SAS to hold the nose high, allowing the whole body of the craft to slow you down. Once you’ve bled enough speed, Action Group 1 will toggle you back to regular controls. Toggle back to air breathing using Action Group 2 if you have any LF left.
