Also, this craft has some issues flying straight due to the asymmetrically attached mass of its new tank. Unfortunately the fuel in the tank won't be used automatically because the AGU doesn't provide automatic fuel crossfeed, but you can pump the fuel from the new tank to the existing one manually. The tank keeps being attached to the target: Supply ship decouples the fuel tank with the AGU. Supply ship exchanging fuel with target through claw: Supply-ship approaching target with armed claw: You now have the tank attached to the ship with the AGU in between.
Here are instructions for how to attach a new fuel tank to an existing ship: You can also use this to add new parts to an existing ship, as long as you are OK with having the AGU as an adapter. You can use this to transfer resources or gain control of an uncontrolled vessel. This gadget can grab onto any part of other vessels and then works just like a docking connection. If, for example, you don't want TweakableSolarPanels, just delete TweakableSolarPanels.dll and TweakableSolarPanels.cfg from your TweakableEverything folder.When you want to dock with a vessel which hasn't got docking ports, you can use the Advanced Grabbing Unit. Turns off crossfeed on Squad radial decouplers to prevent weird things from happening. But, since you might not want all of it, I have broken things out into separate libraries.
In Sandbox, you are free to build any spacecraft you can think. Possible sound improvement if using a digital headphone crossfeed 0. Ejectatrons updated to use new contract constraints, and exhaust damage reducer, and other thermal settings.
Launch clamps updated with new contract constraints. Fuel crossfeed toggle added to decouplers. In Career Mode, oversee every aspect of the space program, including construction, strategy, funding, upgrades, and more. Kiwi engine adjusted: slightly improved ISP, decreased mass, increased thrust. In Science Mode, perform space experiments to unlock new technology and advance the knowledge of Kerbalkind.
