Looks good! but i cant use it

From the looks of it this motor looks great and very high quality, but i only order one initially. I had ordered one with plans to order the second soon after. I ended up ordering the second motor on 1/22/23 and it is currently 3/10/23 with no signs or updates to the tracking number. I emailed propulsion and was told it would be shipped out 2/17/23 and i haven’t heard from them since. I have tried emailing and messaging on their instagram account but never heard back. I understand that Propulsion Boards is a small business and i have tried to be patient but this is just unacceptable.

Really good motors. They are powerful and smooth and feel like they are good quality. You really can't go wrong with these they are solid and robust.

I know they increased the motor cable length from the original flipsky motors but an extra 10cm would be really great.
