Can someone explain how Thrust is determined for the Thermal Ramjet Nozzle? I see EngineMaxThrust and Thrust is far off (10% of max even though I've throttled to 100%). FuelFlow also looks low but adding more supersonic intakes had no effect. Nor did scaling up the Pebble Bed Reactor to achieve more Waste Heat. Nor did moving up to upper atmosphere 20km... I have no issues with the Thermal Turbo Jet which gets me past 700m/s (850m/s top speed). I was hoping switching to the Thermal Ramjet Nozzle at 500+ m/s would achieve an even higher top speed but no luck

KSPI's thermal rocket nozzles are giving me a headache, serious thrust consistency problems. Assembling: 1. Pod 2. Pebble or Molten reactor 3. Liquid fuel tank 4. Thermal rocket nozzle either yields a rocket with zero thrust (https://img42.com/JyLfv) or functions as expected at launchpad. I've noticed it happens more often with the Molten reactor than Pebble bed reactor, and switching from the former to the latter in VAB can sometimes fix the problem. I've also noticed that switching fuel tanks (esp. from a Rockomax to an FTL-800) in VAB can also fix the problem. Anything I should know or is this a know bug?

Okay, thanks, the issue is clear now. Back to the drawing board...

Pretty sure that's only if KSP is lvl 1. I'm level 3.

What are the rules around daisy chaining unmanned probes in Commnet for both science and control? This is my experience: I'm decided to setup a ring of simple unmanned relays in a solar orbit identical to Kerbin's. So for example for 3 relays, you'd see in Kerbin orbit: relay, relay, Kerbin, relay (forming a perfect square). So I went ahead by building a standard probe around the Probodobodyne OKTO, HG-5 High Gain Antenna and RA-2 Relay Antenna. I added batteries and solar panels and off I went launching several of them into Kerbol orbit. The two first probes were easy enough. They are both roughly 8Gm away from KSP and made direct CommNet connection with KSP. I hit a roadblock however at the 3rd probe, which was around 16Gm from KSP but 8Gm from the probe 1. Probe 1 has the HG antenna deployed, the batteries were charged yet refused to relay to KSP. Instead I'm stuck with probe 3 with direction connection to KSP with 1% strength! The table at http://wiki.kerbalspaceprogram.com/wiki/CommNet only gives distances for direct connections so I'm in the dark. What rule have I neglected? Thanks! EDIT: I'm in science mode and KSP is full lvl 3. Range for the relay is 22Gm to ksp.
