Cain,

You can flip the rings over and use the other side. You'll get more life from them that way. Most the time the only thing that really needs replacing is the thrust bearing as that is the part that wears the fastests and causes that gritty feeling. But if your car is serveral months old and you've been running alot, I would do a complete diff rebuld.

I also find if you simply just take the diff apart every weekend or every other weekend of racing (depending on how much practice I've done) to clean and relube everything then the life of diff is extended at least 5x.

you are correct. I rebuild mine every other week just because and the only thing it costs me is diff lube and black grease.

the spur that comes with the graphite plus is a 48 pitch 90 spur(orange) I haven't run the peak motors that often but when I did I ran them at a 6.6 final drive ratio.

The GP promises to make a Losiphile out of me.... though I have to wait and see on Jan 4th, the first race of the year...

one will do just fine. Is there someone at your local track that could show you how to properly set the droop? It may be sort of difficult to understand over the net rather than someone actually showing you.

I'd like to know droop, springs, shock oil, tires, inserts, kick-up, castor, ride height, well, pretty much everything... I need a good starting point... There's a guy here that races the XXX-S and it's dialed, but I don't talk to him much as I hate to bother him.

Thanks so much!

Jits - Jon Fennimore is the Losi guy at Randy's, and here's the setup that he gave me when I got my XXX-S a couple of months ago.

Keep in mind, this is for the "normal" XXX-S, not the GP+.

Front Suspension:

Toe: 0 degrees
Ride Height: 5.5mm
Camber: 1 degree negative
Kickup: Stock
Caster: Stock
Sway Bar: No
Droop Height: 4mm
Pivot Support: 2F
Arm Spacing: Middle
Front Drive: Diff
Standard Pulleys: (42 front and rear)
Upper Shock Tower Position: #2
Lower Shock Tower Position: #3
No washers under the bellcrank or spindle ball studs.
Shocks: 60 weight oil (though I'm switching to 40 - shocks are a bit lazy)
Red Standard Piston
Orange springs
No limiters inside or outside

Notes: Run front diff a little tighter than rear

Rear Suspension:

Toe: Stock
Ride Height: 5.5mm
Camber: 1 degree negative
Sway bar? No.
Droop Height: 5mm
Pivot Support: 0R
Arm Spacing: Middle
Hub Carrier: "A" hole (inside)
Upper Shock Tower Position: 2
Lower Shock Tower Position: 2
Use the outter hole on the suspension arm.
Shocks and springs are the same as the front.


That's the setup he suggested for me at the Celebration Station races, and it's working well at Randy's track. I've added a rear sway bar and will be switching to thinner shock oil when I add threaded shocks this week. Other than that, I'm running the car as listed above.

Also, I'm running the belt pretty loose. Actually, the belt is as loose as it can get without skipping under hard acceleration from a dead stop.

Hope this helps. See ya at the track this weekend. I'm going to practice at Randy's Thursday night to see what, if any, benefits are gained by moving ball studs and shocks around. I don't know if any more can be milked out of the car, but I'm definately going to try. =)

I'm not telling him anything...

Still waiting...although I got so sunburnt at a recent Import drag race meet I don't want to spend another day in the sun racing RC
