My First Sawback

[neospirit]

I just got my first Sawback yesterday. I started the build. I am using Lucas Oil Red N Tacky grease for the metal gears in the axles. However, it seems thick to use on the plastic gears in the transmission. Is it ok to use it? I have always use Tamiya or Associated grease on plastic gears in the past.

I use extra tacky grease on all gears. Most will fling off by the end of the first run and leave a nice coating behind.

I use Red and Tacky on steel gears (axles mostly) but no way on plastic gears - way too much drag even after a few runs. I have a lighter Penzoil tub I've used for years. Tamiya Ceramic is great as well.

I just used some black grease on the transmission gears. I did not use a lot, just a nice coat. I was trying to finished the rails when my wife reminded me about some stuff I need to do for the kids. I will take some progress pics tomorrow.

Congrats on your Sawback purchase! One of my all-time favorite rigs. Do yourself a favor and get the anti-wrap bars from GMade or make some yourself. The only issue I've had with my Sawback is bending leaf springs, but I beat on my trucks and don't always let off the throttle when it's bound up.

I don't use red and tacky on plastic gears. I either use Tamiya white grease or white lithium grease.

I am going to see if I have links I can use before I buy them. Does any one know how long the bars are from eye to eye?

I couldn't find the U-Joints for the drive shaft per the instruction. I found this instead.

Are you sure you checked all the trees? There's double of one tree where you get the matching pieces.

There are no u-joints. These actually works better I think.

Here are all the components

The pin with a hole goes in the square cube through the drive cup. The cube is metal.

Then the thinner pin goes through the drive shaft, through the cube and other pin. They are secured with e-clips.

I actually think this works much better. I already had the u-joints popped out in my G2.

Almost there. I am going to try the Traxxas shocks. They are a little long. If they work, I will rebuild them with stoppers inside.

Oooh, I mistook your post as you were missing those pieces for the other end.

 

[neospirit]

The instruction shows u-joints, not this setup. Is your 4LS comes with this setup as well?

Yeah, my 4LS comes with this setup. Haven't opened my Sport yet, but I'd imagine it's the same.

 

[Rathar3]

No the sport is not the same. It has the round ball type u joints.

 

[OSRC]

Hmm...interesting on the U-joint, mine has a very different setup. What you have looks far stronger.

I am waiting for the paint to dry, so I start to tinker with it. I took the springs off the Traxxas shocks. I may try the stock shocks first. I also made up some anti wrap bars with links I have sitting around.

While I was replacing the servo, I notice the rear is actually heavier. Has anyone try to put the battery up front? It doesn't seem it would be too hard to do.

 

[OSRC]

of course!

I cut down the "motor" and bolted a small tray to it to hold the battery.
