2wd or 4x4?
For 2wd, integy has a aluminum chassis. The nitro slash has a aluminum chassis. The nitro slash one could fit the electric one. You would just need the transmission the other way and a new steering plate.
Wondering why you are going with aluminum chassis? The plastic LCG chassis, I had no issues with. Even with the stock HCG never had any issues with that.
There are carbon fiber ones too on AMain.
