I think the first training module where you're introduced to some of the 6DOF is fine, but only as a familiarization of your control setup. IMO, the next training module to really test your ability to fly are a couple of combat training modules where you have to learn to maneuver while also quickly escaping/hunting the enemy. I feel like that jump is a bit big.
So I propose something in between. It could be a training module or a challenge. Basically, you'll need to fly your ship (Sidewinder or something similar) through an obstacle course (basically get from point A to point B while needing to avoid running into things). So it could be either a) an asteroid field (without the ability to escape the ring so you can't leapfrog all the asteroids) or b) a trench/tunnel (think trench run in Star Wars: A New Hope but with more things to dodge or the Death Star in Star Wars: Return of the Jedi). The goal is to get you thinking about moving your ship in 6DOF. To potentially make it more interesting, it could be a chase or a race.
In an effort to train without losing credits constantly, I've been re-doing the first training module but attempting to run through the asteroid field before heading for the final objective (if I decide to go for it).
