Looking for ideas for a 6s system

[GeckoDragon]

I work at a hobby store, and someone recently gave me an unused Velineon 6s system from an older Traxxas Spartan. I don't have plans for it yet, so I'm looking for ideas on what to build around it. I thought a jet boat might be fun, but I'm open to any suggestions.
Cheers!
