LOL.., "do trainers build bad habits" ~~> is a tough question to answer unless you are specific. If you are planning on only using trainers for all your manipulations, you will never feel comfortable or confident using a live blade (in my opinion). Of course bad cuts arent' much fun.., and I do think since you like trying lots of aerial stuff it was a good choice for avoiding the wet red stuff.

Seems like it might be a good idea to mix in your live blade manipulations for regular openings and closings, and build up your confidence.
Clay has some good thoughts on his site about this, and I think Chuck may also.., don't remember??
You know better than we do what feels smooth and comfortable to you now, so I would definitely use the live blade for the most part, and save the trainer for sparring and doing high-risk airborne stuff.
In my view, the biggest deficit to getting "hooked" on trainers, is that you can be very "sloppy", and build a false sense of confidence because you never get sliced

....so in that sense.., -YES-...trainers can give you inaccurate feedback because you never need to break out the Super-Glue and Neo-Sporin <~~(not to be taken as medical advise). A high quality Balisong with close tolerances will bite you in a heartbeat if you don't internalize precise motor memory through repetition (meaning correctly performed repetitions).., not just flailing around.
Sounds like you are having a blast.., so have fun and don't get too wild with it at first. Try to really feel good about your technique on each manipulation before moving on to more complex stuff.
See ya
