Can check out the weight placement that I used to get it feelin pretty F N good. 3 oz total weight added.

4 x 1/4 oz squares on the front bumper skid plate

2 x 1/4 oz on each side of the front of the battery tray standing up

2 x 1/4 oz on each side at the rear of the chassis, look by the antennae.

what motor you running Cuda???? and NIMH or LIPO.

Motor is 13.5 Novak and it feels like a freakin modified motor in this thing.

I run Lipos, 5000 Reedy and 3200 Orion.

I gotta say, I like sc10 heck of a lot better than slash. sure the slash came pre-assembled, but tuning this thing will be easier than slash. All that 'spec' rules and what parts you can't use...

AE quality is very good I must say. Many have some small issues, but no maker is perfect.

Your 13.5 motor is a brushless one? Or do you mean with this 13.5, the number of turns this motor have (brushed)?

If its a brushless one, do you know how much kv this thing have?

I have here an orion element 10.5 brushless, but I think this will be way to fast for the sc10.

looks good so far.

Correct.

I just set mine up with a 18 tooth pinion and the big spur. I'll try it in a few hours and see how it goes. I'm thinking 4600 kv is more then whAt everyone is running so hence the 18 pinion

I bought mine Friday night and was up until 3 in the morning building. I can't wait to run it at my local track next weekend. :batman:

I'm still building mine, but I had a chance to run my friend's SC10 at HRH this weekend. While it was fun to drive, it did not blow my sox off. With a stock motor, it was quite fast. It was definitely faster than a stock Slash and handles differently. I think you would have to be nuts to put anything more than a 19T motor in this thing. Even a 19T will be difficult to manage. It wont be able to handle the power, period. It's a great truck, but the hype factor with this thing is way over the top.

I see what your talking about. Yes there is alittle play but it shouldn't affect the drive. You can always put a small shim between block and your eclip.

kelvinml 04-12-2009 09:29 AM

I was just wondering how much grease do you put in the diff, do you pack it or do you just put enough to coat the gears?

charly71 04-12-2009 09:52 AM

i think ive got an outdrive catching on an a arm thats why my truck isnt rolling freely. may need to dremel the arm alittle. anybody else had this?:weird:

Thanks, I think this might be just what I need for my driving style.

This hype is more about the type of racing and the scale look and handling than the pure race performance of the trucks cuz they don't have that going for them. If you haven't already raced the Slashes, you're missin out on some simple but serious fun.

Saw and answered your post the other day, yes the axels can hit the arms and may need to have material removed to clear.

Servo Saver?
 
I'm assuming the servo saver assembly is the same for the T4 and the SC10. I managed to shorten a couple of Slash wheel hub pins to replace the missing pins that hold the outdrives in the diff gear assembly. The diff works perfectly and is very smooth, so the only thing left is to replace the stripped servo saver. Hopefully it's the same as the T4 and one of the local shops has them in stock. I'll definitely pre thread it without the spring in it this time.

Well i ran my SC10 yesterday and it definitely needs a lot of tuning to get it right. The biggest mistake I made was to run the AKA inserts! BIG MISTAKE! The track I run on (NorCal Hobbies) sounds exactly like yours. The inserts are way to hard for the rear of the truck. I can not even come close to hitting 3/4 throttle by the end of the straight without the rear coming around on me. Thats with my Tekin RS tuned to the lowest I can tune it. I added 1oz in the front and 1oz to the rear and that helped a bit. I lowered the front ride height and raised the rear and that helped too. 1 degree of camber front and rear and camber links are set to the longest settings in the rear.

The next biggest thing to work on is the diff. Black grease is a little to thin IMO. I am gonna try 10k. One of our track pros noticed that any time I tried to give it some power in the straight, 1 tire would balloon up and steer the truck.

Second. These trucks are hard to drive in any wind other then none at all. No amount of brake could keep the front down with a little bit of a breeze. It effected my slash too but not even close to how bad it effected the SC10. I am thinking maybe a piece of lexan sheet under the front bumper to keep it from the body from being a parachute. Anyone have other ideas?

All in all, these trucks are a blast to drive after driving a slash. Its nice to have some power. Sorry for the long post.

joelwhite 04-12-2009 10:43 AM

You could try putting some vent holes in the body to let the air pass thru.I know the body may be too pretty for that but an idea.

F N CUDA 04-12-2009 10:45 AM

These things are pretty fast with just a 13.5 and they act like they are just too light to stick to the ground.

I'm considering even more weight or going really light on the suspension stuff.
Ultra light oil and springs, go so far as to make it bicycle in the turns then bring it back to more firm from there.

Trying to figure out how to beat down the AKA foams like an 8th scale would do after a set or two of tires, that is supposed to be the hot ticket or maybe a new set of 8th foams that start out a little softer but stiffer than the stockers.

A good heavy coat should be enough. I wouldn't pack it.

beginner4life 04-12-2009 11:04 AM

I think a big lipo would help. Like a 8k SMC

Dragonfueled 04-12-2009 11:32 AM

i ran mine today and it is very assy under any kinda power. Very hard to power slide cause it just comes around. Im gonna put the lower shock mounts in the outer holes instead of the inners. Where you guys running yours? Im also changing the front shocks to 45 weight. I may also go with the proline switch tires like I did on my slash. I like them allot.
My slash feels allot more stable but until I swap tires I wont know exactly why. Ive also had allot more time with the slash.
Whats everyone opinion on the rear sway bar for the t4? I almost think it might be bad to stiffen the rear anymore then what it is now.

I think grease in the diff is the way to go though. With the rear trying to come around on power a stiffer diff will only make it worse.
also the 4600 mamba with the 18 pinion feels pretty good. I would think its somewhere around 35-36 MPH.

charly71 04-12-2009 11:47 AM

ive got ae 2k in my diff havent run it yet but thinner diff oils would probley work ok i definetly wouldnt try 10k man i would think that thick fluid wouls make this little diff a locker. heck i never ran 10k in my 1/8th scale dont see tryin it on a 10th scale. i watched one run yesterday at my track and despite my track being kinda loose the sc10 didnt look very good with the stock set up on it. the rear end just wanted to step out and it didnt wanna turn very well. a longer camber link is definetly a must but for my track its gonna need some tuning.

CaptainHowdyt13 04-12-2009 11:49 AM

I'm extremely frustrated with my SC10 right now. The kit was missing parts, my damn sensor cable is too short to reach the motor, you can't mount the esc far back enough, and for the brief second I did drive it across my living room floor, the transmission/diff sounded so horrible, I am about to just give up on this thing.

F N CUDA 04-12-2009 11:50 AM

Hey Dragondude,
I had the same feeling about this truck.
Very hard to drive, ass end coming around and couldn't touch the throttle anytime.

Definitely do the long camber link in the rear. Night and day.

Get the ride height perfect. WITH the body on, big difference.

ADD WEIGHT. Front, front of battery box and rear of chassis. And again get the ride height perfect.

I ran without the weight in the rear and it was good but still "assy", then I added the weight in the rear and it got pretty planted.

I'm punching this thing everywhere, almost.

I'm gonna do the 30 degree caster blocks for more off power steering and less on power steering in hopes it will cure the assyness.

SKIMAN 04-12-2009 11:54 AM

Well mine is done. on the steering rack issues. first thread the bolt in the servo saver then back out and install spring...This is what i have always done on my asso cars. I also added a little more weight then i have been reading so far. 2.5 ounces in rear and 2 oz in front. I am also running 7000 weight diff fluid... And every factory team part. And i have to say that my trick slash couldnt hold a candle to this thing. very planted, easy to drive, takes the rough, fly's nice, hands down way better truck.. IMO...

Any trouble getting the ride height set with the extra, extra weight?

I used all of the kit spring spacers just to get it leveled out with 3 oz extra.

I bet yours is really planted with the weight.

well i have the factory team shocks that are threaded.. Im running silver springs on rear and golds on front. 35wt front oil and 30wt rear. And yes, very planted. I race on a slightly blown out 8thscale track. And it soaks up the bumps very well. Our slash class is pretty big with 10 to 16 entry's on club nites. I am the first with the sc10, and am already hearing the whinning. Although our rules are, core truck, tires, and body. thats it. So for now i said " i wont collect the hobby bucks"....lol.

This thread moves fast.

Got it done and had a day of track time to get it drivable. Im use to a t4 so this thing rolls around like crazy. Once I got that settled down I fell in love with the steering. The gobs of rear traction really helped the front too. Flys good, its light, all around a home run. For anybody who thought this would out perform a t4 sorry. Not gonna happen. I do think that this tire size is the limiting factor in this class. You can only go as fast as the tire will let you. I love that. Really levels the playing field. we had 5 new sc10 at the track and all were with in .5 sec/lap for fast lap.

We have a mod slash class already so were gona switch the name to pro2 and limit to 13.5. This way we dont bother the slash class. Hope fully it will cut down on some of the crying ?

Nice looking Sc10!

Well almost done with mine all i have left is to build the shocks and install electronics. Here are a few pics of my lid i painted this morning.

Thaks CUDA i wanted to stick with a Trophy Truck/Corr Truck paint scheme.
BTW where are you running yours at????? I am gonna test mine on my backyard track and then probobly venture to Pegasus or OCRC to see how does.

kelvinml 04-12-2009 02:18 PM

Thanks everyone for the tips but I had a question about the shocks. How much rebound should they have when you push them in and does anyone have any tips on building them?

Dragonfueled 04-12-2009 02:29 PM

Hey cuda where you running the lower shock position inner outer? Also what exactly is the correct ride height?

Dragonfueled 04-12-2009 02:36 PM

I might try those castor blocks also. I have no off throttle steering and really tail happy on throttle steering. I added weight like you said but the truck still looks more like a drift car LOL

DiFabio42 04-12-2009 02:56 PM

For the guys who already have a SC10. I have one question.

What is EVERYTHING you need to get this truck running?

Radio + Reviever
Motor + ESC
Batteries
Shock Oil
Pinion
Differential Oil

Am I missing anything?

move your battery back some. I would look at the thickness of the t4 spacers and use that as a gauge for how much. Try a spacer at a time.

Anyone having any trouble with sensor cables not reaching the motor? I have an LRP setup, and I guess I need to order a longer sensor cable. Anyone know where to get one long enough?

Look at my pics for speedo placment. I have a shorter sensor wire on there then the one that came with my lrp speedo.
