I've just purchased my first brushed motor in over 30 years and want to make sure I wire it correctly. It's an LRP V10 Spec6 - 12 x 2. I assume the top half is positive {blue wire}, but does it matter which tab I solder to, and why are there 4 tabs in total? Does it just go backwards if I wire it the wrong way around?

Thanks.

Yes, top half is "+". Either tab on that side will work. The two tabs per side is just for ease of wiring. If you wire backwards, the only effect is it runs backwards.
