The impact probe on the first page- I tried building one but it doesn't have any delta v. - (1) 62.5 cm Thermal rocket nozzle - (1) 62.5 cm "safe-1500" fission reactor - (1) 62.5 cm electric generator - (1) 62.5 cm inline radiator - (1) Probodyne OKTO - plus all the science and comms stuff It won't ignite, says 'flame out- liquid fuel deprived'. I didn't see any liquid fuel in the picture. What am I missing.

I'm just so confused by the parts in this mod. I've searched for guides and tutorials but all I've really found are this, the wiki, and Scott Manley's series. I'm not about to page through 700 pages of random posts and the others don't do much explaining. I've unlocked the Thermal rocket nozzles, 2 kinds of reactors, and some generators and radiators. So far the most thrust/weight ratio I could generate was like .6 with a small stock tank, a reactor, and the thermal nozzle (all 1.25 m). Understandable if the parts are meant for upper stages (and maybe they are), but when I switch to a stock engine I get better delta-v and TWR. How did you all figure out how to use this stuff? I'm loving how much there is to learn, I just don't know how to do it.
