Ya 8 bought two sets of the TB DD75 Kv motors and both sets had one motor that was defective, hit the gas and i would get this crazy skipping, almost stripping sound and chattering feeling…not the motor being loose on the hanger (i think that us standard issue for every set of DD’s from TB… that is an easy fix) mine felt like the like the rotor was skipping past the stator or something like that…i really don’t know what the issue was I just know they got super hot super fast and the reaked of burning death electrical smell after 2 miles and one motor still would spin freely and the other one that smelled of electrical death I got much much harder to turn and certainly would not spin freely.
I ended up with two of the four motors still working all right.
I bought thousands of dollars worth of stuff from torque boards and and just about every shipment something was missing or incorrect I got kegel adapter rings with abec Drive pulleys in the same package they shorted me on sets of AT tires, I bought two batteries and paid for the upgrade to the 4 amp charger and I was sent one two amp charger and one 4 amp charger it just everything had a problem the stuff that works worked well and I will give Dexter credit for being responsive and after much emailing back and forth refunding my money for the stuff that didn’t get sent but I didn’t even try to deal with the motors being defective I just figured I would cut my losses and take my business elsewhere and since then I’ve been a much happier builder.
It always strikes me as time to move on when after you spend four or five thousand dollars with someone they refuse to speak to you on the telephone.
I put an order in for a Lacroix lone Star and had the owner of the company calling me 15 minutes after the my order was placed to go over everything and make sure I wasn’t purchasing something I didn’t need and offer advice on other things I should think about whole different ball game working with companies that will do everything in their power to make sure you get your money’s worth out of what you pay for with them. Good luck!
I also ended up taking the two motors that still worked and fitting them onto a 15-in mountain board truck hanger and installing it onto a double kingpin assembly and then I’ve got a set of direct drive 15-in wide double king pin motors that I love… Lots of filing involved and so far no bending of the axle but I’m guessing that’s just a matter of time LOL.
