Two M's for a change!

I agree that it's likely set to brushless. The store that set it up for you might have made a small mistake in the set-up.

You really just need to get to a different computer and look at the set-up. You can program a few things manually via the radio, but off the top of my head, I don't think motor type is an option. It's in the manual though.

Good luck!
