I find the 2 cell LiPo to be a bit much with the wraith 7k actually. But it makes for a lot of fun. I also run aluminum diff cases, and the viscous diffs don't fit too well in them. By the time you have the diff pinion shimmed correctly, the stub shaft doesn't come out of the case far enough to securely attach the drive cup.

I had a much better go at it with the MLST2 diffs, shimmed up correctly.
