    Upgrading still possible today for an old Emaxx 3906?

    Me and the Hubs were excited to find out old Emaxx 3906 still runs (after sitting in the garage for almost a decade) After much research a plethora of forums and articles on upgrading it were available we decided to upgrade it a bit . What just occurred to us that most of the posts or articles are 2010-2016 not many new posts about it..
    I am still unsure if Kershaw Designs products or kits are still being sold... ( I know the guy died but a different company references the kershaw website and the Kershaw website still works...
    If so that would make life a lot easier... Kershaw seemed to most of the parts we need and a useful kit for our motor upgrade
    Or because this truck is so old is it going to be quite difficult to find the parts we want to replace to give some new life to our 3906?
    If you have any newer /still running suppliers that would be great, besides ebay.
    Our first product was going to be the 3906 700 ho single conversion kit. It seems sufficient for what we wanted to do.
    Thank you,

    I'm also running a 3906 Twin Titan. I blew the ESC and have had nothing but issues trying to find something to replace it.

    I blew the orange ESC and replaced it with EVX2 the blue one and it's been working fine for the last 3 years.

    I think the current Titan motors are the same as the old ones. Should have no problem running a modern esc with those motors.

    The original Titans were different; they were 23-turn motors, had 2 vents at the end of the can, and had fewer fan blades. The newer Titans are 21-turn motors, have 4 vents at the end of the can, and have more fan blades. The newer Titans came out part way through the run of the original 3906 E-Maxx.

    Really? I thought the original Titans were 21t as well. Either way, a newer esc shouldn't have any trouble with older, slower motors.
