Actually i used it in space well above the atmosphere, it drains the fuel too fast and produces verry little delta V (the ship was just a Probe Core, a Fuel Tank, thermal generator, thermal reactor and the thermal launch nozzle)

Ill look it up on the nozzle size and liquid nitrogen, as for reactor i thought only the Salt and Pebble would work with the Thermal Launch Nozzle, i just can't believe it can burn up 5000 units of Liquid Fuel and only give off 500 delta V.

Hello, sorry if i sound like a noob for asking but, im having difficulty using some of the engines provided by the mod, ive checked on many sources of info including the forum post and reddit on how to use but i still fail to get it working right. My main problem is the Thermal Launch Engine, according to the guides and tutorials it needs to be attached directly to a fission reactor (either the Molten Salt or the Pebble Bed), i did that, had a good ammount of fuel availible but to my shock the engine produces poor thrust and consumes the fuel very fast, all this resulting in verry litle Delta V, tried with other fuel variants and the outcome was more or less the same. Again im pretty much a noob with this mod, some engines work okay, the ones with a reactor integrated in them run like the stock Nerv engine, but those wich as i noticed are more nozzle based are inefficient for some reason (poor thrust and low ISP despite in game saying otherwise). I would be grateful for any help possible,
