Brushless monster trucks

[Brow]

I am looking to end up with a brushless monster truck and am leaning towards a Savage second hand and then convert it if I can't find one for sale already done. I am also looking out for any bargains in other trucks, such as Assoc MGT and Losi LST2.

During my research I have read all the threads about buying new, converting and buying electric new. I want a large truck (1/8th scale) because I think they look better bigger and will mostly be bashing it.

Now to my questions:
What scale are the E-Savage and E-Maxx?
Are they the same size as the Savage SS and T-Maxx?
Is the E-Revo the same size as the Nitro Revo? (just an electric conversion)

Thanks
