Maxx Adapters for E-Pede

[skellyo]

I've read a lot on here and various other places regarding using the Maximizer Products adapters to put Maxx wheels on a Stampede. However, the Maximizer adapters are designed for the Nitro Stampede, correct? It looks like the Nitro uses 5 x 11 x 4mm bearings whereas the Electric uses 5 x 8 x 2.5mm bearings...is this right? So would one need to change the spindles out to the nitro version or simply get 5 x 11 x 4mm bearings?

Thanks,
Sean
