They normally fit both nitro & electric.
Also, Raceform bodies is another one that had bodies for the W.E.

Any drivers still run this platform, or have all switched to Black Edition?

There are a few but pretty much everyone has gone to the Black Edition because its better for all tracks .

I'm rocking the WE LV.

Works decent so far. Saving up for a BE later in the summer. Looks like there is some parts compatibility between the two.
