MT410 extension is fairly easy. Might as well use the M2C chassis for that, since it is more of a basher chassis.
The expected
ET48 2.0 is going to bring a few convenience features we find already on the
EB48 2.0:
• quick diff access (which you will likely with basher bumper anyhow)
• more room for electronics
• the appeal of owning the “latest model”
On the flip side, with the older model:
• you have a very smooth and proven platform, both MT410 and ET48.3 are amazing to drive. Unlike the EB48.4 buggy which was considered a bit touchy and hard to pilot.
• a ton of aftermarket support the new model won’t have before a while
To your question of new vs. old: if your racing, you may want to wait for the new Truggy, if you are bashing, get the MT410 and get immediately access to all 3rd party stuff from M2C and t-bone.
To your question of MT410 extended vs. ET48: not much of a difference if you ask me. The ET48.3 has longer towers, aluminum shock caps, a wing and body posts mainly compatible with the ugly stock body. The MT410 has slightly shorter towers with the SCT body mounts that make it easier to adopt any truck body with the right wheelbase. If you’re not racing, I don’t think you’ll see much difference in driveability. Just tried a friend’s extended mt410 truck a few days ago and it is a great RC. The aluminum caps and wing are things you could easily add to the mt410 if you wanted.
Conclusion, for a basher, the MT410 is hands down the better choice IMO. Get yourself the amazing T-Bone bumpers and run a good looking body, it will make you happier than the more race-appealing features of the ET48. You can extend that MT410 to make it an awesome high power and speed basher (recommend getting m2c chassis for that).
