I have been having spur/pinion issues with my truck since I built it. With the motor clocked over the best pinion/spur combo I can run is 17/96. And the gear mesh on that ain't too good, either. I shaved the trans case a little, but I don't want to go any futher than I have.

Since I can't find any easily-obtainable 48-pitch spurs larger than 96t (I found some delrin and aluminum ones up to 150 tooth but they're only available on-line and they ain't cheap)

So, I went to the plex. And I picked up a 72t 32p Kimbrough Spur and a 9t Robinson pinion.

This thing is HUGE!!!!!! It's not even a spur gear anymore. I think it qualifies as a flywheel!



This gives me a final drive ratio of around 39:1.

previously it was closer to 32:1

And if THAT doesn't do it, I've got a 7t pinion coming and I picked up a 76t spur. That'll get me 59:1

And don't tell me I should just get a 35t motor or whatever.

I like my Multiplex 600. It's like having a 500hp full-race engine in a trail rig.

Nice, how hard was it to clock your motor plate like that. I've been thinking about trying it with mine.

[JavelinSST390]

Not that hard, with a band saw. A jig saw would work, too. But mine is REALLY hacked up. It's ugly as sin. Also have to drill a couple new holes, and remove the side posts from the transmission housing (not hard with a dremel.)




I know there's a template out there for a clocked motor plate. I'll look for it and post you up a link.

You get your new chassis made yet?

[kwkride]

I haven't made the chassis yet. I have doing some planning on the design. I think that I have what I want, but I haven't started cutting yet.

I was going to start cutting it out, then I realized that if I do this it would be really good to have the axle mounted servo already. Then I thought that if I cut out a servo mount, I don't have any links that would work for steering.

So then I put my truck back together and went out and drove it. haha

I've also been thinking about clocking the motor plate. That would really effect my chassis design. I realize that getting the weight lower is a good thing, but how much difference does clocking the motor make? The new chassis design is a lot easier if I stick with the stock width, and I'm not sure that hanging the motor out the side of the chassis would be a good thing either. I'm guessing that side to side balance is nice to have.

My WK steering servo is on the axle and I used the stock draglink and used 2 losi snap on ball cups with some 6-32 allthread to connect them.

and the steering on his sons truck works great that way! I saw it in action yesterday.
