Hi guys, noob here. I just bought an edge chassis with a Pro Slot PS-2003 speed fx 16 d motor. The motor has two solder tabs installed on the motor. Do I install the motor with the tabs facing up or down, also, how do i tell the positive tab from the negative tab. Thanks for the help.

i would put the tabs up but it dont realy matter what way they are as for the postive an negtive they should have marks on the molded end bell to tell them apart
