Try deactivating the receiver. My relay only has microwave transceivers in "relay" mode. Relay mode both receives and sends out. Your tranceiver that you have in "receiver" mode is probably taking away all the power the relay is trying to use. I'm not sure if orientation matters; my relays have six transceivers (2 for each axis) in case it does.

Kicking the thing up into orbit with Hyperedit solved the entire problem. Brilliant! Maybe add an error message like "Static Pressure Too High!" when this happens? Is there any way I can contribute to the development of this mod? I've been looking for a way to brush up on my programming skills and this seems like a decent outlet. I might not be able to add new material without a lot of help but I can at least do some spellchecking and whatnot.

Absolutely. I'm going to give you a link to a zip file with several screenshots (can't figure out how to upload them here and imgur won't let me upload because file sizes are too big). The first proves that I have enough radiators, the second is the reactor info window, showing that it's generating power, the third is the thermal generator, fourth and fifth are the engine itself, one after just activating and the other after activating and timewarping a couple hours. As you can see, the engine has everything it needs, it just refuses to consume fuel for some odd reason. https://mega.nz/#!npY2haAR!1xHQS7pdRyHrTDW1xNG_lj68z7yJH1Lb5bG2lBpROno Glad to see this is not localized to my install. Try the thermal launch nozzle, has the same problem for me.

Got a couple of bugs for you. At least two of the KSPI-E engines won't vector with yaw controls. They'll vector with pitch/rotate controls, but won't respond to yaw. I had the problem in .17 and just updated to .18 with no improvement. So far I've had the problem with the Thermal Launch Nozzle and the Closed-Cycle Gas Core engine. Very hard to launch rockets with this issue. I tested this on a development build with no other mods and still had it. The other bug has something to do with TweakScale. I wanted to see if I could make a small plasma engine plane, so I used TweakScale to size down a molten salt reactor + thermal generator to 1.25 meter size, switched propellent to liquid fuel and launched it. Engine on, receiving MW, but won't use fuel or provide thrust. The exact same setup works if I scale the reactor/thermal generator to their starting size. The scaled-down plane works with the ATTILA thruster. This bug is localized to my in-progress save. I don't really know anything about editing save files, though. Is there any advice you might give to fix this? Or should I post this to another section of the forum? Please tell me if there's any other information you need from me that might help.
