I think part of it has to do with the way you drive. Even when I bash I drive in a very controlled manner (no just full out "lets just nail this jump as fast as I can" type of driving).
This really prevents me from doing a whole lot of retarded stuff that ends up broken things when you miss the jump and careen off into a wall at 40mph.
So, in reference to that, the E-Revo is much easier to keep under control at just about any speed. Its suspension is far superior to anything I have driven.
However, I will say that it is a complicated truck so you have to be very familiar with it and think hard about how changing one thing will effect the truck as a whole (this is mostly in reference to the suspension adjustments).
Other than that, I have pretty much had 0 issues with my Revo 2.5R, and if there are any issues with my G2R it is only the result of running 6S Lipo on a 1940/7 and doing (HARD) runs on pavement where there is gobs of traction causing me to blow drivetrain parts (so I just got Mike's V3 diffs).
The Revo is a very solid truck and will need minimal upgrades to keep complete reliable.
what i mean is that on the flux the esc and motor donīt get much cooling air as on the e-revo because the way they are mount...
and more air means more cooling for both!!
The metal chassis on the Savage is a plus, I've seen people snapping the chassis on the E-Revos (and I snapped a metal nitro chassis on my conversion). The Revo's handling is a ton better, but the Savage is tougher. The plastic driveshafts on the Revo are durable enough IMO, and when they finally let go they're cheap to replace. I don't know if HPI has updated their driveshafts for the Flux or not, but I know people with Savages that shear the ball end of their dogbones right off.
I think they're both solid and it kinda boils down to which you like the best. I know people with nitro Savages and they're always rolling them over, and I hate running out to prop a truck back up. The Revo has a weaker chassis and bad diffs. With an aluminum diff case you don't get nearly as much case flex which is the big killer of the Ring and Pinion gears on the Revos and the new I-beam style diffs are a huge leap forward from the old ones but in the future you may need to upgrade them. The Savage diffs are a little tougher out of the box but if you see the videos of the standing backflips on 6s and think that would be cool to do all the time you will quickly be shearing teeth off of the pinion gear. Again, they're both good trucks and each has their weaknesses so I'd go for the one that tickles your fancy. I personally like the "truckiness" of the Savage yet the sophistication of the E-Revo.
All I ever wanted was an honest weeks pay for an honest days work.
