To add to this adding weight to the rear of the truck will tend to make the rear step out on exit, think of it like a pendulum. adding weight towards the front will keep the rear in check and add exit steering. Remember its always a balance game between the front and rear.

Wow!

Great discussion guys... so far I'm getting quite a bit from it and its helping understand the truck's handling characteristics better...


By the way, I stumbled across this while doing a search for some mod parts that have been mentioned... looks like a really good deal for anyone looking for the whole package!

I think the FWD to AFT weight transfer is a big thing like Mantis said, i can still feel it with the 49/51% set up, just because of the sheer weight of my truck. I think its like 6lbs 5 ounces now.

Along with the pendulium effect, i can see this truck being a handfull.

Anyway, the plan is on indoor tracks, i will run the single shorty. Either transvers or inline. I can swap the chassis back and forth, my brace is all bolt in, so its and easy swap.

Hopefully i can get the weight down under 5.5lbs or so with a single shorty, and removing some led up front, and maintain the weight split.

Big outdoor track this week thou, so i am excited to get it out there and see what happens.

Thinking about buying a SC10 4X4 FT and have a few Qs.
I have a SC10.2 right now.

Are the body mount holes in the same spot on the body 2WD to 4WD?

I will be running on a medium sized medium traction clay track. What Tekin motor would be a good start for that in 4X4? I run an 8.5 in my SC 10.2 and it is just about perfect for me.

If I stick to a 2 cell Lipo will a 120A ESC be O.K. ?

Tires interchangeable between SC10.2 FT and a SC10 4X4 FT?

Must have mods for running on clay?

Thanks for any help!

For motors, its pretty common to run a 540 4 pole motor. The Tekin Pro4 4000Kv can work very well with that track size and the lighter weight helps with the weight bias. If you go with an ultra light style SC10 4x4 setup, I have heard of people even liking the Pro2 version.

120A ESC if its anything like my SP GT2.0 Pro will work great. I use that ESC in my Tekno now and its excellent for the money.

As for must have mods when running clay, personally I would say start with the stock FT vehicle, +3mm wheels, and go from there. You may find that you will want different springs. But the vehicle is in its element on smaller good traction tracks.

Body mounts and wheeels are common with the SC10.2. Cain provided most of the other pointers. If you can run the saddle packs it is more balanced than the stick pack. 2S is normal in this classification.

I am running the shorty pack forward transverse and I am very pleased with it's performance on medium sized clay tracks. I would strongly suggest the RCShox c-Diff. Also look to RC10.com for set-up suggestions.

Krom - Yes, do share your experience at the big outdoor track!

Cain - Thanks! But I don't need the whole kit. Just thought of sharing it as it looks to be a good deal since it has a lot of the mod up-grades already on it.

I ran the regular SC10 and swapped bodies between the 2 trucks with no problems. Would assume the updated 10.2 body posts would be even better.

8.5T in my 2wd and 5.5T 550 in my 4wd. The 4000kv Pro4 would be perfect IMHO, since you are used to the 8.5T in 2wd.

After updating my old 2wd to hexes on all 4 corners, I was able to swap tires between trucks. As I understand it, the 10.2 is already hexed.

Only "must have" mod that I can think of, and this is just my opinion, keeping in mind that I hate throwing money at problems.....RCShox Center Diff. Rather than slipping and turning the energy into heat like any slipper setup will, it will send the energy where it needs to be.

On a medium traction track, I have my rear upper camber link on the insides of the tower and the outsides of the hub, and that seems to lock the back end in pretty well.

Has anyone tried those Schuur Speed 4 poles in a sc10 4x4?? How do they pull compared to a tekin, want to got to a 540 motor. Also I noticed Wild Cherry you have the stock chassis, have you had the Exotek? and if so which one do you prefer?? I run on a med outdoor track with natural dirt and a med to large clay on occasion.

Prefer the stock chassis for its lighter weight .

On low traction conditions or outdoors we are adding extra ballast next to the servo ...( 1oz to 1 1/2 oz on each side)

Yeah I liked the stock chassis when I ran the stick,when I converted to saddle packs I added the Exo at the same time but pulled the 2oz of weight off. it doesn't seem as responsive with the exo, I was thinking of going back to the stock with the brace. I was wondering though if I ran the brace with the exo if that would help? Feels a little squirmish with the exo and no brace

When using the Exo chassis, no need for the chassis brace ...

Less flex will make the truck feel like that because there is very little chassis movement to absorb the track.

WC - Wow, really?! I would have thought the other two ends would still flex a bit despite the stiffer center aluminum chassis.
