BL Revo tranny - DIY

Hey just an FYI, you don't need the one way back on there as a spacer, I have been running mine for a while now without and it works fine.

This mod works exactly the same as the hub I milled to replace all of this, basically you are locking up the second gear to the shaft instead of the clutch doing it. If you reassemble correctly the gear will be held into place on the shaft and won't slide, the shaft is turned down at the end and won't slide further into the bearing than it is supposed to. You can lock the tranny in either forward or reverse and it will work, I have my locked in reverse and the motor is just setup to go the other way.


Good work around dude!

Been there, read it. You were the inspiration for me to try this method! I liked the idea of using the Revo, but was skeptical of the durability of the epoxy, especially on the nylon gears. Time will tell if any of our methods have durability issues.

Yep, thanks. I figured that out too, after putting the tranny halves back together for the umteenth time. Was pretty obvious, but obvious is always the first thing ya miss, eh?

I like your machined part! Very well done.

And locking up is what this is all about. It basically creates an E-maxx tranny out of the Revo tranny - but allows for all other stock Revo drivetrain parts to be used, and no chassis mods need to be made. Others looking to convert a Revo can use what they have, without buying another trans.

Thanks to you guys for the kind words, and for the information/inspiration!

Nice Job Cadtech. I think I'm going to use this method on my second e-revo. I've already got my first one cut up and disected too much to be used with anything but an emaxx tranny. I'm one of the no bling guys that dont feel comfortable dropping 300 bucks on the Gmaxx frame.

Hopefully both of our approaches will work great. BTW: the epoxy is rock-hard. It makes a solid sound when I tap on it with a screw driver, almost like knocking on a piece of aluminum, just a little more dull. When I had my tranny apart trying to figure out how to lock 2nd gear, I thought about somehow using screws to connect the gears, but was afraid I'd weaken them with the holes and screws. I guess the only bullet-proof method would be to create a new gear that is a combination of the 2nd gear and that other one, or something to that effect.

It's neat how several people can come up with so many different ways to achieve the same result.

That's exactly what I was after: using more stock Revo parts. Mike was extremely helpful in getting some of the custom parts I needed (like the drive
shaft) but it would oh so much easier to use what's out there already. I don't mind modifying the chassis and fabricating parts, but if one of those parts break, it's not like I can run to the LHS to get a replacement, I'd have to re-fabricate another. Ugg.
