I just bought the DKLM gearboxes for my Abrams, but they arrived damaged. The metal housing is actually broken where the bearing is seated on the drive shaft. Didn't buy them from DKLM direct so I'm dealing with HobbyRaw to see if they will send me a replacement. The drive shaft is bent too so the gear box took a nice hit in shipping and therefore broke right through the housing. Also the motor PCB cracked.
