Help with bl revo

when I give it gas it doesn't wanna go but it does with no torq And when I hold on to it just the cvds go and not the tires help I thought maybe it was the pinion not touching the spur. But that can't be cause the Cvds move I'm using a e maxx tranny and its in 2 gear hElp

Why does only the front left and right rear cvd spin?????

You are missing the drive pins behind the hexes, or the diffs are shot. Take all of the wheels off and make sure the pins are behind the hexes.
