...did you light the fuse?

We won't know until we know what kind and size of hull (hydro, mono, cat, etc.) you're running and what prop...and even then you will still have to be careful on your first few runs. I would run for about 20-30 sec. then bring it in for a heat check. If it's fine...run a little longer and check again.

Which size motor is it? Here's their datasheet.
