After a bit of reading I have decided to go with the rcshox center diff in my new truck. Start with 5 pins and go from there from what I have read. Is this the best route to go? Also Should I be using the recommended 5000 diff fluid or is there a better option in the opinions of you experienced racers. I see some running different weights in the front and rear, what would be the reason for this?

It depends on the class you are running. what are the rules for your track?

As for Kv to Turn. The lower the turn in general the higher the Kv and faster the motor.

Definitely confirm what the rules for you track are. For SCT 4x4 in general its open mod, ROAR limitations if I recall correctly are 540 2 Pole motors (not much use this as 4x4 SCT is hard on the motors), 550 2 Pole, or 540 4 pole from memory here, confirm to be sure though.



Good choice. In general I would suggest you start with a setup of 7 - 10K up front, and 5K in the rear. The rear really don't change much from that value.

Different weights give you different handling characteristics. The free hudy offroad guide you can download from xray's site is quite useful with breaking down setup changes, you should download it and give it a quick look through, keep a copy with you at the track.

So I have the M2C toe block coming in the mail. Any owners of it have tips or best setting?

Cain

cool. Feel free to ask any questions!

What conditions are you running on? If you feel that the rear of your vehicle currently wants to step out on you, try 3.5 degrees toe in, the max. See how that locks it in for you.

As for the antisquat settings to be honest really didn't feel that much different compared to the toe in change as far as hoe noticeable the improvement was, but, it could be that the conditions I used it on weren't the most beneficial to the change.

I am kind of new to this and do not have the toe block yet but I have been doing a lot of reading and it seems many are running 3.5 with the mc2.

loose stuff for sure. Indoors carpet I was likely 2.75 degrees when I still had mine.

I have searched for this answer and cannot find it anywhere, stock pinion is 14 and stock spur is 62. I want to put my reedy 4900kv in the truck, but cannot find an answer on if I need to change the pinion gear. Anyone know the answer? My head is going to explode due to info overload.

Hunter, with 4900kv 14 may be too big but depends on the size of your track. Watch temps at 14 and go 13 off too hot.

Cain is dead on with 3.5° toe in for anything but stupid high bite carpet (IMO).

Stock anti squat is better everywhere, add more and you have a very loose rear end... as more anti squat will do. Unless you are once again on carpet, then all rules go out the door and experiment.

I am assuming this is the motor you are talking about:

http://www3.towerhobbies.com/cgi-bin...?&I=LXBVYU&P=7

if so, I would recommend that you look for a proper 550 sized motor at a minimum, or a 4 pole Pro4 style motor (tekin, etc).

To use the motor you have, you would need either:

- get a bore reducer so you can mount the 5mm pinions to your current motor
- use the 48 pitch gears and appropriate pinions

Your gearing will be critical however and you will really need to watch temps.

I suggest that a good all around motor to use is the 540 Pro4 4000Kv motor from small to medium sized tracks. A higher kv motor would be great for larger tracks.

You win for your C-Diff choice!

My setup differed a little from Cain's, I started with 7k/5k and settled at 5k/5k. That's all preference and indoor/outdoor. 7/5 would be better outdoor where Cain drove.

I ran 6 pins outdoor to let it diff out to the front more and 7 to 8 pins indoor where I usually drove. The pins are super quick to change out and experiment with.
I didn't change diff oils at all. Just changed the pin count to go from indoor to outdoor.

that was something I wanted to try but sold the car before got a chance, plus, the access to the diffs don't make swaps very easy lol.

For indoors, i was running 8 pins, man it felt great. and the 2.75 degree block setting really freed up the rear end.

Thanks guys, I think I found what to do, there is a lot of you running the tekin pro 4 and rx8 setup and there is a lot more info out there on this truck with that setup than with the 4900 reedy. Found the rx8, pro4 4000 and 4600 for $250 from a guy locally getting out of it so I am going to get it. Just use the reedy in T4.1. You guys are very helpful on this thread and I appreciate that. I will continue to try to find answers on my own before I ask but thanks for answering when I cannot find it.

Yep, 8 pin will balance the power more F/R and send more power to the rear compared to 6 (or anything lower than 8).
Better for high bite, maybe 10 would have been optimum for carpet (stupid high bite).
