hydrazine RCS burns all available fuel in seconds

[Beechwood Chip]

I've been messing with the same basic lifter design for a while.  I've flown it manually from lift-off to docking with a station a few times, and now I just use mechjeb ascent/rendezvous/docking.  I've done it dozens of times.  I usually disable RCS until orbit, then turn it on for the rendezvous and docking.

I decided to replace my place anywhere linear RCS ports and RV-105s with retractible resistojet RCS curved and inline arcjet RCS, which use hydrazine.  So, I replaced my FL-R1 with an X200-8 full of hydrazine.

The problem is that I run out of hydrazine immediately.  I leave RCS disabled until I'm ready to dock, then enable RCS and the docking autopilot.  The RCS jets go for about 2 seconds and burn all the hydrazine.

I can just go back to using the monoprop RCS jets, but I figure there must be some way to use the hydrazine RCS jets effectively.

What am I doing wrong?

Here's my ship and mod list.

What mod are you using to add Hydrazine? I don't see Real Fuels on your mod list and thats the only mod I've used which adds that. You might have better luck in the thread of the appropriate mod.

Hydrazine in IFS burns very easily, which might be your problem.
