I wouldn't say it's a direct fit to the ecx amp mt. The arms fit right on no problem but when's it comes time to fit the hinge pin brace back on, it doesn't fit properly. Bc of the new rpm arms being much more beefy so I'm not complaining just saying u will have to remove a small bit of plastic on the hinge pin brace. Not a big deal.
