Ok, first, I am fully aware of InfernalRobotics, I just wanna post THIS one which uses a vanilla module.

Special thanks to Yargnit for telling me and all other 100-something livestream viewers of his

Motors: The 2nd-to-last frontier

Ok so, while watching Yargnit's KSP livestream, he was experimenting with a module. He told us! Yay!

Apparently it was implemented in 0.24 but was never used (hence the word "Test" in the module). It's a fully-developed motor-like module. It works fine, with tweakables too. No problems of any kind with the system, just that it was never coded into a part. So I coded it into a part, and now EVERYONE can use it! By the way, the module is ModuleJointMotorTest.

So basically it rotates the nodes connected to it. It has 3 modes: Park, where it stays still, Neutral, where it's neutral, and Drive, where it rotates. The speed and force can be changed w/ tweakables, and there's also a reverse. You can also set it to a throttle > speed setting to, it's useful for planes and helicopters. When making helicopters, it is recommended to put a Neutral motor below the rotation systems, so it doesn't spin you. Uh, blah blah blah no SAS blah blah thank you for downloading blah.

P.S. Struts and KAS wires/pipes will in fact obstruct movement. Loss of life due to excessive spinning is not covered by warranty. Warranty will be voided if used to fling A-C-Class asteroids at things.

Me - coding it, period

I completely do not own any part of this mod, other than nothing really. In fact, I don't even own the thumbnail of this mod (it's one of Squad's flags). I simply coded it to fit the requirements of a motor. Textures, model, KSP, and the motor module belong to Squad.
