Firstly, many thanks for working on such a useful piece of kit!
Using Smart RCS, it appears clicking off the "Use RCS for rotation" button means that MJ will still turn on the yaw/pitch/roll actuation on my RCS modules, but when I hit wasdqe it temporarily turns them off. So *my* rotation actions don't use RCS, but MJ still feels free to use RCS for rotation. This is my experience with both dev and master.
Q: Am I understanding things correctly, the behavior I'm seeing is expected/intended? Or is it a bug (presumably an interaction with another mod) which I should try to isolate? I ask only because everything I find via Google suggests "turn yaw/pitch/roll actuation toggles off" should make MJ use the reaction wheels, but clearly that's not what's happening.
Q: Assuming this is normal behavior, is there somewhere a setting for "actually leave the RCS rotation actuation toggles off, and only use the reaction wheels"?
Thanks!
Edit: This is for a 4.7-ton lander using the Munar Excursion Module, so the RCS is pretty powerful, and a bit off-center. When I turn the RCS thrust limiter down to 15%, the problem (mostly) goes away. Could the Attitude Adjustment module be seeing things get wildly out of envelope, and start using RCS in desperation?
Edit2: This github issue #979 being marked as a bug suggests this is not intended behavior after all?
Perhaps relatedly, I was also separately having exactly this guy's problem with the rockets stuttering and MJ firing RCS to turn off-target. This problem also went away when I turned the RCS thrust limiter down to 15%.
The moral seems to be that very powerful unbalanced RCS thrusters, such as found on the Munar Exclusion Module, can cause problems for MechJeb. Luckily the fix is easy - turn down the power, or balance the RCS thrusters.
If any of this is still of interest, I'm happy to supply logs, .craft file, whatever helps. Cheers!
