RCS no fire

[Zeniden]

My RCS ports do not fire. I have plenty of Monopropelant and the thrusters are symetrically placed. My key bindings for translating thrust are my number pad keys and right shift / right ctrl. The mods I have are

Mechjeb

KAS

KW Rocket

Kerbal Alarm

Kethane

Did you press "R" to turn on the monopropellant system thus lighting the green light on the top left of the navball?

Is that little green light for RCS lighted?

Is your ship manned? If not, is there power? Make sure the answer is "yes".

It was the "R" button. Thanks so much. I can't believe it was that simple.

I should have joined this forum and asked for help before spending a solid week learning how to control Kerbal jet packs... Suddenly figuring out that SHIFT was what I was missing was the gaming moment of the year for me...
