I don't know what benefit a torsen diff (if that's what you mean by "spider") would offer. I can see using it in the front or rear to keep one side from unloading on corners. But the combination of stiff suspension and sway bars helps that a lot. Otherwise, it kinda acts like a solid shaft if used in the center...

I used 90wt diff fluid (which was the thickest that I had on hand). I am going to try the diff and then try the center spool. I just wish somebody made a heavy duty center slipper to go with that solid shaft....

Yeah, that would be nice. But believe me, the tires slip enough. Seriously, I don't think the lack of a slipper is a big deal. Other than controlling take-offs, the other use of a slipper I can think of is to absorb drivetrain shocks when landing from jumps. Do you plan to jump this?

Those are good points...no jumps planned for this car. I am going to give it a few runs as is. If it diffs out too much and eats the front tires I will definitely swap for the solid center spool. I just did not want to keep the 2-speed because I NEED reverse and I used all of these parts (center diff) because I had them on-hand.

Are you sure you used the right oil??? That there is shock oil, no good for diffs!!

I will definitely get a vid for you all...eventually.

As for a body...I am planning to contact Team3six to see what he can do for me. Any cool ideas on themes? I was thinking something associated with Tesla or maybe nuclear energy.

dude,
i love Tesla!! my wife and i actually had one of their songs played at our wedding. 5 man acoustical jam is a great album. i just love the acoustic stuff. hmm, how could you incorporate a Tesla theme? "Signs, signs, everywhere signs. blocking the scenery, breakin' my mind. do this, dont do that, cant you read the signs?"
i know they didnt originally write that one but sure made it sound good.

I think he was refering to Nikola Tesla--the scientist!

lol, when I saw "Tesla", I immediately thought of a Tesla coil, not the band (especially with the reference to nuclear energy). But the band was good too.

thank you.

I bought a lot of the parts over a long period of time when they were on sale or when I had some good coupon codes...but as an estimation:

$329 DM-1 Spec
$50 RC Monster motor mount
$75 RC Product Designs battery tray and diff top plate
$125 three Ofna Spider Diffs
$270 MMM and Neu Castle 2200kv combo
$100 JR Servo
$285 Flightpower 5S 5000mah battery
$85 Spektrum transceiver
$95 HPI D-Box gyro (not pictured)

YIKES it adds up quick.

I could be wrong but silicone fluid is silicone fluid...the stuff I used was 9000cst viscosity not 90wt. Its pretty darn thick and seems to work fine in some of my other trucks.
