Correct. BUT, I've found this level of detail is often too much for a 5 to 6th grade level audience.

So I usually start with "what if the back rotors go a little faster?": it tips it forward, beginning a series of operations leading forward motion (like turning the wheel of a car away from center -- what happens if you keep it turned?)

I've also found that words matter: "attitude", "differential", "pitch", "velocity", "acceleration", etc. -- may be hard to access, and simpler terms like "faster", "slower", "speed", "tipped" are usually more broadly understood.
