Less rear toe-in means less speed gets scrubbed, which leads to better accelleration and higher top speeds. Using less rear toe-in is only an advantage if the car is still stable. If the car starts to slide going through the corners as the result of less toe-in, then speed gets lost due to the tires sliding (and in some cases due to the car hitting stuff due to lack of control). I'ved tried running as little as a half degree of rear toe-in. The car is very fast, but also somewhat out of control like that. With 2 or 3 degrees, the car feels a lot more stable in the corners, though a little slower due to speed getting scrubbed.

What does the rebuild tool do?

They are pretty straightforward to rebuild ... in what way do they help?

I still like 2 degrees.

The less toe-in at the rear, the less speed you scrub (tires fighting each other) but the less stability that you have. I tend to like some stability so I like 2 degrees. It's always worked well for me.

Hey guys, I was going to sell my tc3 but decided to keep it. My question is what maintainence am I missing? right now all i do is blow my car off with an aircompressor. Also are bearings for teh steering rack really important?

Thnx


One last thing, anyone have any MVP tips to make it go fast? Everyone is killing me on the straight...I have the correct gearing though. i think it is also do to my batts...

thnx

i know the nitro guys like that set up, never seen it done in an electric before though, not sure if it would work. it seems like that set up would break the rear end loose alot.

Default Diff Rebuild Tool -- RPM

Hooked. There are two Studs (for lack of better word) that stick up and pins through them. One is for Associated, the other is for Losi. For the TC3 {with palstic diff halves} you set the short diff half down on the stud. The pin holds it from turning. You then put on all of the parts. 'D' ring, gear, balls then grease. Then you put the long side on with 'D' ring stuck (with a very little dab of grease), then insert the diff screw with the thrust washers and balls already installed and lubed. Using the allen driver, tighten till you feel it bottom and then back off the appropriate amount. Then you can slip the halves over the flats of the bottom of the tool and turn the gear and see if you have it tight enough. Check on RPM's site and I think they have a picture of it. Pretty Goof/Proof after a couple of uses.

Default RPM Diff rebuild tool....OOOOPs

Gentlemen: It has come to my attention that all this time I thought that my tool was built by RPM (not really sure who makes it) but right there on the face of it it says RACERS EDGE. My apologies.

Thnaks for your indulgence.

less drag in the rear mainly, and for me it allows me to turn in harder w/o kicking the car sideways. when i run more rear toe, the car wants to dive into the corners. with running foam lately this is something you dont want to happen. smooth is fast

Hey All,

Just built up a TC3 from parts I had laying around, it is smooth but not ultra smooth...or should I say free...any hints/tips about freeing up the driveline, I made sure I didnt tighten down the diff cases to tight or the shaft braces, but the care just doesnt seem as free as my other TC3's....

Thanks in advance...

Trixter,

I do pretty much the same thing with 2 allen keys when I do a rebuild ... I slide 1 allen key through each of the slots in the end of the outdrives and check to see that the gear does not turn when both outdrives are stationary.

I realized this little trick after cooking (melting) both front and rear diffs within 4 very frustrating races of my first rebuild (I bought a used TC3, rebuilt the entire car except the diffs and ran it for approx. 40 races before the rebuild in question).

If you want to make a diff tool just bend a piece of coathanger in the shape of a U and use it to hold the two outdrives

A friend of mine has a Tc3 and he wants to know which shaft is better. OF course i drive the xxx-s so i don't know anything about it. So what's a better shaft to get? The AE aluminum shaft, AE carbon shaft, or the IRS aluminum shaft?
