I'm waiting on my second motor the same thing happened to me.
It took 2 months to get but that was allegedly customs fault.
I had it working great for three days and then the motor just stopped.
Lucas worked with me via email to trouble shoot but in the end he was able to send me a cap to make the unit somewhat usable while the new motor is shipped so I appreciate that.
I'm told Lucas is working things out so hopefully i will be able to post back soon with good news. I can totally understand that sh*+ happens but I have to admit it is un settling to hear others with the same problem.
Lucas seems genuine and I have confidence in him to do the rite thing.
This has the potential to be a great setup and a game changer for my system so hopefully they will get things sorted out soon.
