Assistance is required somewhat

[TimberWolffe]

It's probably bad if your engine uses Infinite/sec fuel...right?

Not sure what happened, here's my .cfg

       jettisonDirection = 0 0 1     //in XYZ format; +Z is same direction as engine thrust, or some other direction you set.

}
}

and then a picture

so yeah...help?

I don't think you can use .8 Try 0.8

[TimberWolffe]

I just tried 0.8 and 1.0, neither worked

At least one of your propellants has to have mass.

The Quantum Vacuum engine in my mod runs primarily on ElectricCharge as well, but to make it work I had to add a small amount of another resource called VirtualPlasma, used in a very small ratio. There's a ModuleGenerator in the engine that ensures it always has some available.

[CaptainKipard]

TimberWolffe if you don't know how to add your own resources then check out the dev links compilation, and let me know if this solution works.

Don't worry, I know how to do that. I just didn't want to have to c;

[TimberWolffe]

Okay that's fixed it, now it gets a very small probe up to Duna on 1/4 tank of fuel! Next comes mass balancing and price since the Em Drive is basically a solid copper tube
