A mod that add Test Flight option without charging funds for parts

[DeepOdyssey]

Basically, whenever i play career without reverts i have sandbox profile to test my creations. But it's time consuming to switch profiles and then copying craft files to my other profile.I know it's a bit cheesy:D

Holodeck or KCS will add what you are looking for.

Thanks, this one work flawlessly.

Note that HoloDeck's feature set is currently quite limited. It's based on Kerbal Construction Time's simulation feature (and will eventually replace it), but if you want more features you can look at KCT. You can disable all the time requirements for building things in the KCT settings by disabling build times, if you just want to use the simulation feature. Link is in my signature.
