  1. MandatoryRCS This plugin revisit the stock balance between the overpowered reaction wheels and RCS thrusters which are useless outside of docking situations. It does not propose a more realistic simulation of reaction wheels but is a collection of tweaks aimed at limiting their functions and balancing the gameplay. Reaction wheels are turned into stabilizers, preventing your vessel to spin out of control and keeping it pointed at the direction you choose in the SAS autopilot. But they have a very low (and somewhat realistic) torque power when the pilot or the SAS request a pitch, roll or yaw rotation. This mean that like in real life, most crafts always need a few RCS thrusters (and propellant) to have orientation authority, but you still get most of the playability benefits of overpowered reaction wheels. As a side benefit, the plugin also fix the "timewarps rotation stop" stock behaviour, and introduce a few related features like keeping the vessel oriented toward the SAS selection in timewarps and when switching vessels / reloading the game. Features Reaction wheels nerf Reaction wheels have two different torque power, the stock one and a heavily nerfed, somewhat realistic one. Nerfed torque provided on pilot or SAS rotation requests. Stock torque when SAS "Stability mode" is turned on. Stock torque when the vessel has reached the SAS selection (prograde, normal, target, etc). Torque output is affected by the vessel angular velocity : the faster the vessel rotate, the weaker reaction wheels are. Pods and cockpits built-in reaction wheels can't be controlled (they don't respond to pilot/SAS input) but still provide SAS stabilization. Reaction wheels in probes cores and independent parts can be controlled. Hiding of irrelevant reaction wheels right-click menu options and action groups. Rotation persistence trough timewarp and reloading Timewarping will not stop the vessel from rotating. Rotation is restored after timewarping, switching vessels or reloading. Rotation is not continuously calculated for unloaded (on rails) vessels, for minimal performance impact. SAS autopilot persistence trough timewarp and reloading The vessel will keep its orientation toward the SAS selection when timewarping, switching vessels or reloading. The SAS selection is remembered and restored when switching vessels or reloading. Customization Features can be enabled, disabled or tweaked in the ingame "Difficulty Settings" menu. Instructions & notes Download & source I highly recommend that you grab it from CKAN ! But you can also get the latest release and source from github Requirements This requires the ModuleManager plugin to work. You can download it here Incompatibilities (Semi-)Saturatable Reaction Wheels : can still be used but the reaction wheels features will be automatically disabled. Persistent Rotation : can still be used but the SAS and rotation persistence features will be automatically disabled. Recommendations RCS Build Aid (Forum post) - Editor plugin to help you place your RCS thrusters efficiently. RLA StockAlike (Pictures) - A light part packs featuring (among other things) some super useful small RCS thrusters, monopropellant tanks and engines. Disclaimer This is my first plugin and I'm far from a skilled programmer, so the code for this may be ugly. As far as I know, it does the job and doesn't break the game. However, keep in mind that I don't really know what I'm doing. If anybody has the time to review and comment my code, I'm open to suggestions and pull requests Thanks @MarkusA380 for figuring out how to make vessels rotate, you saved me a lot of time ! The whole KSP community for its awesomeness ! Licensing This masterful work of art is released under the unlicense. So public domain, feel free to do anything, especially updating this plugin if I'm not around. Changelog Known bugs and glitches Getting out of timewarps with the SAS direction hold activated input a large roll "kick", most visible at high timewarp levels. I tried a lot of things to find out why this happen or fix it, and failed. When switching to an unloaded vessel with its SAS in "target", "antitarget" or "maneuver" mode, the orientation change is applied a few frames after the vessel is unpacked, leading to the rotation event being visible to the player. Won't fix as this is minor, purely cosmetic and fixing would require large modifications. v1.2 for KSP 1.2.2 (feature) Ingame settings menu with compatibility checks for SSRW and PR plugins. They can now be used alongside the plugin, incompatible features are auto-disabled. (feature) Torque output on pilot/SAS input is now very low instead of disabled. (feature) Torque output on pilot/SAS input is still disabled for all reaction wheels in manned parts. This can be overridden/customized trough a "isControllable" parameter available in the module config (see the default patch CFG for more about that). (improvement) In SAS target mode, reaction wheels provide torque only if they have closely reached the target first (less "magnet effect") (improvement) Refactored several things in ModuleTorqueController, now a bit less dirty. (improvement) SAS target hold in body-relative modes (pro/retrograde, radial, normal) is now disabled when the vessel SOI change. v1.1 for KSP 1.2.2 (bugfix) Fixed SAS orientation being applied when not reached on initiating timewarp (woops) (bugfix) Tweaked a few things to prevent the perpetual SAS roll overshoot. v1.0 for KSP 1.2.2 (feature) The torque output from reaction wheels is now affected by the vessel angular velocity : the torque output decrease when the angular velocity increase, down to a minimum of 5% when the angular velocity reach 45° / second. (bugfix) Fixed reaction wheels providing a bit of torque when switching SAS from stability assist mode to a target hold mode after loading a vessel (fixed by forcing module deactivation every fixedupdate) (bugfix) Fixed SAS overshooting its target when using RCS (Fixed by explicitly setting reaction wheels torque to 0 when the module is disabled) (bugfix) Irrelevant reaction wheels action groups options are now hidden Perhaps planned features Reaction wheels saturation over time when landed. (Maybe) Make reaction wheels able to "help" RCS thrusters by providing torque when they are activated, lowering the RCS fuel consumption. A part pack of RCS thrusters, MP tanks and orbital MP engines (soon ) Realism notes The way reaction wheels work with this plugin isn't realistic. This said, in lowering their torque output to realistic values for maneuvering, this plugin make the playstyle a lot closer to the reality without cutting too much on playability. In real life, reaction wheels and control moment gyroscopes (CMR) can provide only very small amounts of torque. For example, each CMR on the ISS is rougly 1.2 meter wide, weight about 280 kg (source) and provide only 0.258 kNm of torque (source). Now compare that to the 5 kNm provided by the 0.625m, 50 kg small reaction wheel in KSP.
  2. - my first mod...: this mod provides few parts that increase stability for vessels or planes. download: Spacedock known bugs: mk3 reaction wheels don't have colors(fixed at ver 1.1.1) mk3 reaction wheels doesn't have Tweakscale(fixed v.1.1.1) mk1 drone core cannot control directions and reaction wheel not moving, however, it can give SAS to the vessel IDK License: remember to report bugs here changelog: 1.0beta mk3 RW added 1.0 release added mk1 drone core 1.1added tweakscale 1.1.1 bug fixed (need mk3 exp.pack to work until I fixed that problem) 1.2 op funny flags added 1.2.1.1this mod doesn't require mk3 expansion anymore and flags added 1.2.5 added a realistic version of mk3 reaction wheels and engine(original+unrealistic version) 1.2.6 added agencies 1.2.7 added one more part and tweakscale for engine and new part, engine are more powerful 1.2.8 mk2 reaction wheels (using mk2 DC texture} 1.2.8.2 add readme and license txt 1.2.8.9 (planning) fix mk1 drone core bug and tweak scale for mk2 reaction wheels and find bugs and de them *P.S. I'm not good at programming and modeling.so pls forgive me vote for parts : vote and this mod will be dead untill ~July 10 thanks for @Warsoul for helping me to find problems and the conclusion: there are a big problem when downloading so the cfg in the mod comes messy and were missing some }s reason of the problem... maybe i'm using mac there were no problem when i redownload it I WILL TRY TO FIX IT
  3. I have a space telescope that's a tad difficult to train on a target that's far off... when I maneuver the telescope, there's a bit of drift back and forth as SAS tries to settle it on target. I was thinking I need to add more reaction wheels to make the training a bit more precise, but perhaps I'm going the wrong direction? Might I actually be overpowered with my reaction wheels? (What I have right now is the HECS probe's internal reaction wheels...)
