I have the original MT410, at ET410 2.0 and now the MT410 2.0. I use shorty 3s packs in the ET410 as a lightweight basher and found it to be my favorite RC, even over the MT410, as a backyard basher. However, I did manage to break something on it every few packs while the MT410 rarely broke. So the MT410 2.0 gives me a lighter more agile feel while also being more rugged. It's the best of both worlds, and now that I've put a castle mamba X / 3200kv setup in there and am running on 4s it's also a 55mph triple-backflipping beast with amazing air control.
The only issue I've had on the 2.0 so far is rear dogbones popping out, but that appears to be because I had too much droop and too little negative camber in my initial suspension setup.
I tried a couple other brands, but couldn't help but come back to Tekno... they just handle so much better and I really love building my own kits over RTRs or rollers (though I wouldn't mind an
ET48 2.0 to round out the stable and am looking for a roller/slider if anyone's sellin'

)
Oh.. and regarding body mounts, I wish they offered a factory threaded system instead of body clips, but otherwise it seems fine. Improved over the original MT410, but not by miles.
