REQUIRES VELCRO ROCKETS v1.1 - http://www.orbithangar.com/searchid.php?ID=3388
This is the JupiterIIIx addon by andymc modified to launch the DGEX using the Velcro Rockets module by sputnik.
You do not need to download the actual Jupiter3 addon.
*Note*
This scenario does not include any cargo with the DGEX. The Jupiter3 will get the DGEX to a stable orbit, but adding cargo may require modification of the thrust values in the Jupiter3 core config file.
Sorry but I'm not an uber coder and I adapted the velcro coding from an existing launcher to create the Jupiter3 config files.
Press O to start autolaunch and autopilot. Target autopilot heading can be changed in the scenario file.
Press J to jettison the DGEX after Jupiter3 MECO.
