Well don't go on the TRX forums as they will tell you they are the best thing EVAR, flame you if you disagree, then procede you give you a long list of suggested upgrades. lol

So my honest review after several years of ownership:

Pros: Way way more durable than the old emaxx. Prolly still much better than the new emaxx. Handles well for a MT, and is flexible enough for lots of things, and lots of upgrades availible if you are looking for a money pit, and even the dinkiest LHS carries Revo parts if nothing else.

Cons:
Well...overall I would say its overly complicated and components are undersized for the job at hand. Granted there have been numerous updates and hopups put out to help fix, but they are stop gaps which can't overcome some fundamental design flaws. They also cause you to be nickled and dimed for little breakages and upgrades. Granted none are too expensive, but totalled up the end up making the truck quite expensive for what it is.

Complicated: Working on it is a pain compared to a last gen Savage or a 1/8 platform (truggy, etc.) Diffs are hard to get too, and requires alot of dissembly of the truck's suspension. Tranny is a pita as well. Yes you can get different rockers for this and that, but requires you to have all those different parts (rocker arms, pushrods, spring sets, ballends, etc; enter the nickle and dime..) and a fair bit of time to change it all around. My guess is most people leave it just as the P2 rockers and never change it.
The 4-gear diffs are small and weak, and need way hvy oil compared to 1/8th scale 6 gear diffs and tend to leak alot due to crappy o-rings.

Hard to tune. I've yet to get the rear suspension where I like it. It needs the nearly the heaviest springs available just to not drag its ass on the ground. => Way heavy shock oil then too. Then the rebound is slow. I guess TRX released another "hopup" as in variable rate shock pistons to help this out, put again another N&D to fix a flaw. Not only that, the shocks are quite small in size, like 1/10 scale, with very little travel. The effect of having such hvy springs and oil to compensate is that there is a lot of force generated in the suspension. Rocker posts tend to bend, ballends wear out fast (the plastic shock ends just rip off..) and push rods get bent as well, unless you upgraded those as well (n&d.) Compared to a std shock design on a tower, there is little fine tuning availible, and requires a lot of screws to be undone and extra parts swapped out to adjust. Whereas on a tower design, one screw in the shock cap, and you can move it to a more progressive or more linear shock rate. You can do this in 5min at the track side, vs 30mins and a bag of spare parts on the revo.

Lameass plastic sliders stretch out. You can get cvds, but you really need to get RPM arms to guard against arm breakage, but that means the arms are so flexible the cvds will get bend or pop out quickly. Keep and replace the sliders then.
Whatelse? Tie rods in rear axel carriers means they can get bent, and tend to get the rear toe out of alignment, esp as ballends wear and get sloppy. Savage is like this as well, but least you can go to a C-hub design. Revo's pillow balls means you are stuck w/
tie rods.

In the end its an expensive truck. You can buy plenty of parts to fix or patch the above, but if you get a truggy off the bat it will come with better equipment standard at about the same price.
EG:

A-main list a Jammin X2 kit for $520
Bl ed Revo is $660
However, to get the upgrades and parts close to a truggy, really you need the Plat Ed Revo roller for $620 (I know it has a 3.3 motor, but bear with me...)

So in the end, you can get the BEER (bl ed e revo lol) and spend however how many $10s or $100s upgrading it, get the Pl Ed and save on upgrades, or just get the X2, convert it, and put a bit more upfront, but end up with a much tougher and far better handling truck in the end (and will not require many parts or upgrades) which is far easier to work on and tune. The same pretty much applies for a pure basher with the savage (but needs a bit of work, but not too much.)

IOW: Revo= a fun but an expensive jack-of-all-trades/ master-of-none truck
....IMHO
