It has two dowels on the leading edge. And two bolts at the trailing edge.
I prefer the bolts over rubber bands any day.
I had rubber bands on my old trainer, and it was such a hassle. But that's my preference.

It's pretty aerobatic for a trainer. It's got a semi-symmetrical wing with little dihedral. It flies great upsidedown, and will even do a bit of a knife edge, but I'm still working on that. Rolls, loops, etc... just fine.
