BL Revo using Revo Transmission? - Page 8 - RC-Monster Forums

BrianG · 10:46 AM

Well, my original idea for locking the Revo tranny into second gear needed to be rethought. After running this afternoon, I was cleaning it up and noticed the tranny acting funny. So, I took it apart and discovered shredded epoxy all over the place. Strangely enough, the rest of the tranny gears look as good as new! :032: I was expecting to see a complete mess, but I'm not complaining. :)

So, I tried something else to lock that shifting hub into the second gear. I filed some round spots at three locations around the metal hub and then screwed three 4mm bolts into the gear. This should be strong enough, but only time will tell.

I don't know if anyone has mentioned this (don't wanna read through 8 pages!) but there is a conversion on ebay to mate a brushless motor straight to a revo tranny, and looks to be pretty easy. I think it's about 80 bucks.

that's quite expensive, considering you can buy a two speed maxx motor for about that money. and besides that, the bolts Brian is using most likely do about the same

Can you post a link to that adaptor you are talking about mwe-maxxowner? I did a search for both Revo and brushless, and Revo and transmission but didn't find anything.

As far as the bolts go; they seem to be holding up. Went through 6 cycles (about 1.5 hours) of track time with no problems. The whole idea of using the stock transmission was to be able to use as much stock parts as possible to make repairs easier and cheaper.

Okay, I was a little mistaken, it's not on ebay, searched all night for this link, but here it is! :)

He posted this on here, i commented him on the 'battery-tray'

BrianG · 10.14.2006, 03:53 PM

Lol, sorry. Didn't mean for you to go to so much trouble!

Actually, if I remember correctly, that was simply an adaptor to use other 32p (0.8m) spurs with a 4-bolt mount pattern.

Yeah, too bad he dropped the MOD1 setup..

I bought two of those kits. I have a bunch of pictures but I haven't had time to do a write-up yet. You actually get both CF pieces for the batteries and the speed controller, along with an awesome aluminum motor mount that bolts into the factory holes, the 32p spur adapter, and the magical 2nd gear locking adapter.

Using that with a FOC and removing first gear gave me forward/brake/and reverse with the stock Revo tranny. I skipped on using the 32p adapter after some mesh problems and just run the Mod 1 pinions.

BTW, he also sells each component individually if you email him. The motor mount is actually the most expensive piece of the kit (about half the cost).

FYI about the motor mount part of the kit: His mount is nice, but it's made for short motors. The Wanderer XL is longer that the Novac motors, so the end of the motor would hit the suspension when compressed. The motor needs to sit higher to compensate, which changes the mount a bit. Then, if you don't use the adaptor hub for the spur gear, the mount has to sit closer to spur, which again changes the mount.

I actually started to work with him to design a new mount for larger motors, but stuff came up, so I ended up making my own. It's not that hard really, except making the motor adjustment slots.

If my new 2nd gear locking scheme doesn't work, I'll email him to get the special part he made.

Ahh, I've only used it with the Novak HV and a Fiego 8L. Both of those fit fine, although the mount could come forward a good bit if you don't need the 32p adapter. If you look at my pics, I'm pretty sure that's why his ended up where it is. Also here are some pics of the receiver fit for those that are interested.

Even with the spacer gone, there isn't enough room for an XL size can if the mount sits that low. The front of my mount sits flush with the flywheel opening, and it still wouldn't fit. Actually, the XL can itself might just squeek by the suspension arm, but unless the wires are at the top, they'll hit the suspension arm. I really wanted the motor to sit lower too.

I might email him about that second gear locker. It's small and nicely done. I'm going to be picking up another tranny soon so I'll be able to have a spare. :)

Brain, have you tried to do anything with that center diff?

You know, I was getting ready to take the tranny apart to fix my epoxy mess and I remembered it and took it out. But when I started working on the tranny, I totally forgot about it until after I put it all together. :007: :007:

So, no, not yet. I just didn't feel like taking it all apart again.

That is a nice looking mount!

As far as the XLs go, would it be possible to mount the motor the other direction? Ie as it lays across the center? That would be more optimal from a weight balance standpoint. Obviously you'd lose the Rx and possibly the st servo on that side, but that's not a biggie.

Edit: Does anyone know where the Revo 3.3 ext chassis was lengthened? Front/back, 50/50 40/60, etc?
