ssspconcepts · **Revo Mod 1 Spur -** 01.22.2009, 06:35 PM

Anybody know where I can get a Mod 1 spur that is compatible with the stock revo/maxx slipper and that is also larger than 40T? 51T is really what I'm looking for but cant find one that will fit on the stock revo slipper.

Anybody have a workaround?

Revo spurs are titchy yeah- the most common work around is to use something like MGT spurs I believe, they have a 51t spur thats MOD1. At worst you just have to enlarger the holes slightly for the screws to fit that bolt it to the slipper plate thingy.

If you don't mind using 32p, Jato spurs work. IIRC, maxx and the E-Revo use 32p system on the Revo style slipper as well.

If you want specifically mod1, then modifications will be necessary. Or, see if Mike could make an adaptor to allow you to use your 51t spurs...

What about a savage slipper assembly? Has anybody tried one of theses? Seems like this woud work fine:

My problem is this:

From Revo

My motor "bottoms out" on the tranny case before the gears mesh together. I guess I could use like a 25T pinion

But I don't think that would mix well with the electronics. I was thinking that since the savage slipper also rides on a 5mm input shaft that it would be a fairly straight forward mod.

MGT Mod 1 spurs are your best bet. They come in 46,47,49,52T. Tower has them.

Do you have any pics of the installation/mod? Thanks.

Open up the center hole slightly so a 5x10mm bearing will fit in it. The revo uses a 5x11mm bearing stock. Then just drill out 3 of the smaller holes to 5mm so that the posts on the slipper can pass thru and reuse the existing bolts that hold the spur on. I will try to get some pics of a modded mgt spur next to stock mgt spur. Really easy, you can enlarge the center and side holes with a body reamer if necessary, as long as the center hole is concentric the spur will run true.

Linc, I saw in some older threads that you were tinkering with a savage slipper...would that work?

The MGT spurs work great with some modding. Here's a 52 tooth Mod 1 on my E maxx with a Medusa Motor and a 18 tooth Mod 1 Motor gear.

Just don't mind the carnage. I had an accident. LOL

Notice, there is alot of room in the adjustment to allow for a bigger motor pinion or a smaller one. It's pretty close to the middle with a 18 tooth.

I have tinkered with savage slippers, but they are not as good as the revo spec slipper. Best to just mod the mgt spurs and run them. I never did put a savage slipper on a revo, only slipper swap was putting the revo spec unit on an old emaxx tranny.

Mmm... are those plastic spurs really 32 pitch? For example this 49t? It says in the tech notes that it's 32 pitch though it looks more like mod1 to my eye.

All mgt spurs are mod1, tower's info is not correct.

Thanks for the relieving info, lincpimp - I already ordered few and read the info afterwards and was like "Nooo!!!"

I have done the mod to run the MGT spurs on a revo slipper, it's not hard but it still limits your gearing choices. I have been running the stock 32 pitch gears on my E-REVO for almost a year now and haven't stripped a gear yet. There are plenty of 32p spur gears to choose from so 1 pinion gear and you have almost a 10MPH range you can gear for by changing the spurs that only cost $3

Well, on mgt spurs you have 52,50,49,48 and 46... Plus you can go down to the 36,38,and 40t revo spurs if you run certain size pinions... Seems like plenty of choice to me. I do have 300 bucks worth of mod1 pinions though... Must have 2 or 3 in each size, some hardened and some not... Small parts like this can really add up to some serious cash, so I understand if you do not have 30 cars to use them on it is good to have cheap alternatives for gearing.

Personally I use BG's speed calc and pick my gearing that way... Always works for me!
