can you lighten a converted Revo without compromise?

I've seen people buy Steel Tony's screws for all high stress areas in the E revo, and 12.9 alu screws for the low stress area's. That only reduces weight a little though.
A single servo setup is recommended too.
A light tire and rim combo, summit/stock axles instead of CVD's if you have those.

Can't think of anything else right now :)
