Hi @xfghjuytwq34567ujn and welcome to our forum!

Can you share a picture of the parts you have received?

Thank you.

weird it didnt upload the first time around
it came with the cube orange kit.


this also came with the blue robotics t500 thurster its some kind of computer that makes thebattery give electricity to the motor, but its ends dont connect like they didnt give another cable or wire to put into the battery, but this end connector. any ideas?

and they didnt explain which way it connect to the cube orange, like if black goes on top or white goes on top or if it even goes vertical into the cube orange or which one it goes into.
