I thought I had read some reports on the smart diff that claimed it was more sluggish - but I can't be 100% certain of that.

Have I told ya'll how much I despise the closest LHS to me?

I stopped in on the way home today to pick up some 100wt. I looked around a bit, didn't see any so I asked the kid. He kinda looked at me and walked over to these little tubes of grease and said - "Diff's dont use oil, you just use the lithium grease". I must have given him my special "look", 'cause he asked "So hat are you trying to put oil in? Diff's only take grease." I started to explain, and he got an even funnier look when I said the word Truggy, and he said -"Oh, we dont carry those brands".........ugghghhhhhh!

Kids like that give us LHS employees a bad rep. He should come visit the store I work at, he'd leave after just a few hours :lol:

Smart diff's don't result in faster lap times, this has been proven over and over.. but past that typical smart diffs result in ~12k on throttle and around 4k off throttle obviously depending on your springs and how many etc etc.


20k center w/ the 2.5d should be sufficient, but with a 1y you need around 30k to keep the unloading on the fronts to a minimum.

I have 20-20-5 diff setup with slipperential and no unloading with Low Profile racing tires

yea i read that stum, i just got the truggy like this and win every race ive been to with it almost, so i dont wanna change it lol

If it aint broke don't fix it :)

I got out this afternoon to run the 8T in the dirt today, and I must say that I'm more impressed now. It turns great in the dirt, and for acceleration, it outran the brother in laws HV4.5 in his emaxx fairly easily (which it should have, I know). No, its not the brute force that the Flux and the Revo displayed, but its damn quick. Handling was noticably better in the dirt than it was on grass, and had just a little unloading of the front tires if I really ran it hard.

Glad to hear it !

Just wanted to update with my experience with the 8T so far.

Had the 8T out at the beach over the last week along with my Revo conversion, the Flux, my relatives FLM Maxx, and an E-revo. Well, some of you may have read my update on the Flux and the FLM/LST shocks (not good so far). I have to say that far and away, this 8T is great. It was easily the fastest of the bunch on the track we made in the hardpack sand, and held up great - until I decided to send it off a ramp over the break wall by the beach (it was about an 8 - 10 foot drop onto the soft sand). Something, somewhere inside the diffs or the motor got bound up. It runs, but it when you let off on the throttle, it completely locks up the wheels (I did have motor braking set to about 10 or 20 percent - but after the jump, its like its on 100%). With everything off, I cant push it by hand at all. I pulled the center out and checked it, but it was fine. I'll have to pull the front and rear to see what those look like - I needed to do that anyway, since I never opened those up after I bought it.

One thing I'd like to try to do with this thing is to find a way to put some different shocks on it so that I can also make it a little more bash friendly - ie., get it up off the ground a little more.

Bondonutz 09.08.2009 02:54 PM

I was able to double up the shocks on my Lightning Stadium Pro2 basher, You should be able to do the same ?

I'm geared at 16/47
Center Diff is now fresh with 50K - I havent pulled the front or rear yet.
I had it out for a few minutes last night to just run it up and down the street to get a feel for the gearing and check temps.
Anyway, I'm less than impressed with the off the line pop, acceleration, and overall feeling of speed. This is in comparison to the way my Revo ran with the same motor, my Flux (maybe not a fair comparison), and my past Maxx's and other rigs.
I dont recall what my settings on the MMM were - but I know I have never turned down the punch control more than 10 to 20%.

Is this "normal" for a truggy? What steps does one take to give it that "out of control" acceleration feeling that we are all so attracted to? I assume that going up in diff oil weight is the only mechanical tuning solution - besides gearing. BTW, with the Tekno set up, and the 47 tooth spur, it looks like 14 or 15 is the smallest pinion I can run - my 13 wouldnt engage. I do have a 48T Robison spur that I can put on there also....

change your front and rear diff oil, also your center. change the front to 7, center 10, then the rear 3. thats my set up, this is a good start, then when you get the hang of things you can change oils
