Something that I didn't realize when I started playing and neither did the duders in the QL was that you can bind specific parts to specific keys (and in some cases change some other settings, like wheel speed). The tutorial mentions this feature VERY briefly in passing, but the implications are SIGNIFICANT. With this ability, you can

• Bind the left and right side wheels to different buttons, giving your vehicle tank controls that don't need fragile steering hinges/pivots
• Make your vehicle faster by setting the wheels to spin twice as fast
• Control/aim a weapon with a steering hinge or pivot that doesn't interfere with your actual steering
• Set cannons into firing groups so they don't all go off at once

This is really a crucial feature that I feel is not conveyed clearly enough. Maybe you all figured it out immediately and I'm just dumb, but I wanted to mention it just in case.

The way you set the key bindings is with the little wrench icon at the top of the screen. Click on that, then click on a part. It'll bring up a menu showing the key bindings and settings for that part. With your mouse over a listed key ("Up" for example), press whatever other key you want to use for that 1 part (like "W" for WASD controls or numpad 7 for the left side wheels on a tank).

Yeah, I feel like the tutorial needs to explain stuff like that way better, because watching Drew play through the tutorial (which for him was the 2nd time), that functionality is not particularly apparent.

This changes everything! I bought it after watching the quick look, but I couldn't get passed some levels because I tried to add pivots and it kept causing my siege weapon to fall apart. Thanks for the tip!

I was able to figure this out fairly early on just by hovering my mouse over the various options to understand what everything does.
