New Schumacher CAT SX2

[jimmy]

Schumacher have released news of an update to their CAT SX 4WD electric buggy - the 'SX2' features many updates to improve strength and performance that the team drivers have been testing over the last few months - notably the new 'Big Bore' dampers seen in testing and already a confirmed feature of the new Cougar SV buggy make a welcome addition to the SX2 kit.

Other updated include plastic moulded hinge pin blocks instead of the easily-bent alloy items on the previous car. These should help absorb knocks without damage and are combined with new stronger suspension arms.



3 belt transmission with efficient low tension belts running on large size CNC machined pulleys.
Adjustable internal transmission ratio (2.2, 2.4, or 2.6:1) to optimise ratio for brushed or brushless motors.
Motor rotates the same direction as the wheels creating a car with superb jumping responsiveness and no torque steer effect as is common with shaft drive cars.
Super free ball diffs with silicone nitride balls, pro spec thrust bearing, and steel diff outputs.
Strong steel universal joint driveshafts.
Smooth twin pad slipper clutch with easy access adjustment running on a New tougher 5mm black spur gear.
Unique clamp motor mount to fine tune weight distribution, and allow motor changes without affecting gear mesh.
Industry standard wheel fittings.
Layshaft or front one way Speed Secret option.
Overdrive front pulley Speed Secret option.
Optimum weight distribution with stick pack lipo layout.
New 2.5mm aerospace grade carbon fibre chassis and top deck.
Horizontally split transmission housings for ease of maintenance and diff access.
Ultra narrow chassis design to minimise grounding on roll.
New Stronger front & rear wishbones.
New Stronger 4mm front pivot block screw.
New Lighter plastic eccentric housings for adjustment of belt tension and diff height.
Rigid servo mount directly onto transmission housing for precise steering.
Dirt protected with tight fitting body and undertray.
O ring wing mount system to avoid crash damage.
New Max sized rear wing.
Class leading suspension geometry with durable components and a range of optional alloy parts, offering adjustments to set up your CAT SX2 to any track conditions.
New more durable plastic pivot block system with the ability to adjust track width and toe in/toe out.
Adjustable rear roll centres, inboard toe-in/toe-out, anti squat and track width using optional alloy block Speed Secret parts.
Adjustable front roll centres, inboard toe-in/toe-out, track width and rake angle using optional alloy block Speed Secret parts.
New Pro spec big bore shocks with titanium nitride shafts, CNC machined pistons with recessed ‘e’clips, threaded collars, twin O ring sealing and diaphragm volume compensation.
Strong and rigid 4mm carbon fibre shock brackets.
New lighter plastic steering arms.

Thats not a bad price for the 4WD , kinda makes the 2WD look over priced too me.

[mikeyscott]

Very nice.

The bits that interest me are:

New Lighter plastic eccentric housings for adjustment of belt tension and diff height

New Pro spec big bore shocks with titanium nitride shafts, CNC machined pistons with recessed ‘e’clips, threaded collars, twin O ring sealing and diaphragm volume compensation.

New more durable plastic pivot block system with the ability to adjust track width and toe in/toe out.

New lighter plastic steering arms.

Smooth twin pad slipper clutch with easy access adjustment running on a New tougher 5mm black spur gear. Using RW spurs, but interested in the mounting system

I'd like to know if they've changed the servo mounting system as the original I thought wasn't very good. Many other cars you just bolt the servo in on the Cat SX you've got this lining up rubbish. Too much what if on the mounting.

Glad to see the alloy mounts aren't included....

Other than that, my Cat SX has all the other bits :D

Also noticed that the Cat SX has come down in price. Doesn't bother me as Cat SX is my car for 4WD again this year.

[purplenut]

Any body want to buy a sX lol,nice looking car iam realy loving the big bore shocks,but iam saving up for a sv at mo so sx2 will have to wait...

[bigred5765]

new top deck and battery retainer to

[frogger]

Do we know when it will be available?

[purplenut]

yea i noticed that,they have drilled out enough room for the esc wire always was a pain,and battery bar looks wider this will also help.:thumbsup:

[Dave Dodd]

availibilty is the same as the couger sv - towards the end of March to mid April (Spring) Hopefully.. :D

[mikeyscott]

Going to be an expensive month with the new Cat SX bits and Cougar SV

[MHeadling]

Looks really nice, some good improvements over the original

I wonder how much it will cost to get to Sx2 spec from an original Cat??

Exactly my thought, although I already have the new stiff chassis and top deck, if they are the same.

[mikeyscott]

Just noticed the rear wishbones don't have any holes on the rear...


Godo to see the weedy rear wing has gone.

[jim76]

bit odd how the cougar S1 has cheaper shocks, but the cat S1 will have the big bores?

[mikeyscott]

Indeed, didn't spot that..

[MattADH]

The allen bolt that holds the front mount for the battery strap needs tightening!

[Alfonzo]

Don't know what they put in the water down in Northampton, but the Schumacher boys are hustling a great game right now. :thumbsup:

[purplenut]

Ive just had conformation from schumacher that both the sc &sx2 will be relised mid to end of march.23rd would be cool as my bday :thumbsup::thumbsup:

[mikeyscott]

End of March then.... and then a question of whether they'll make enough to maintain stock levels etc.

I have also been told there won't be an upgrade pack for existing owners...

[purplenut]

oh thats a real bummer well best start saving even more pennies.

[burgie]

Am I missing something here?

I bought a 2nd hand cat sx last week and installed the servo in it in about 30 seconds. Didn't have to line anything up. Two screws, and job done.

When I mount my Sanwa it doesn't fit perfectly between the gaps, so you end up scewing down on only a percentage of the tabs, rather than the whole tab if that makes sense.

Indeed bummer, oh well more money to spend.

[burgie]

So that would be an issue with your servo, not the cat :p.
I do understand what you mean now though!

looking at it though, with the exception of the big bore shocks, the SX2 appears to be a lesser spec'd version than the original SX, especially if you have the stegger brace on it and the modified layshaft.

Maybe the plastic hangers and diff adjusters are there to keep the cost down so the big bores can be included and the kit remain at a reasonable price.

I wondered if that was the case, but the Sanwa looks the same size as the other brands with the lugs etc. May see what a Savox looks like in it from my B4.

What servo are you using?

I have thought that too as it reduces costs. Another though is they may be moving away from the spacer set-up for toe in etc. I.e. you want 3 degree toe i there will be block A, 2 degree block B and so on.

Can you take a picture of your servo mounting and sending it to me?

[burgie]

I will do....I have a Futaba s9550 in mine, it fits a treat, although prior to putting that in I trial fitted a KO and that fited fine too, but it's not as powerful as the futaba, so out it came.

Thanks,

If it's a better fit my Sanwa (#ERG-WZ) Digital ERG-WZ Servo will move to something else.

[bigred5765]

i have the savox in mine, but i fitted a sanwa in a friends, there is no issuse mike i can tell you that there all pretty much a std case size,

[mikeyscott]

I thought they would all be a standard size. Oh well I'll just check it over again.

[bigred5765]

may be the mount or screw that holds it is bent

[mikeyscott]

True, time for a strip and check...

Cheers,

[mikeyscott]

I see some of the parts have gone up in the listings on the Schumacher site.

Alloy Front Blocks; 7.5 deg - Cat SX2

Alloy Front Blocks; 10.5 deg - Cat SX2

Wonder what these are as compared to the original Cat SX.

It may well be cheaper to sell the existing Cat SX and get a new one than upgrade :(

[David Church]

This car looks very nice indeed:thumbsup:

[mdb_75]

I doubt it if you have the chassis already! The only other big difference is the big bore shocks, but I can't see me gaining a lot from having them. The other upgrades are just little bits and pieces that you will/can replace over time as the original bits get worn out and/or damaged.

[Dazzler]

Don't know if I've missed something - but does anyone have a comprehensive list of the differences?

[mdb_75]

I'd say it's just everything that's listed as new in the specs?

[Dazzler]

Are we looking at an advert somewhere or the Schumacher website?

[mdb_75]

First post on this thread and SX2 page on Schumachers website.

[bigred5765]

post one of this thread and schuy site

[Beanie]

Throws down the gauntlet to X Factory somewhat after the Cougar and now this!

[Dazzler]

Ah yes - I don't know how i've missed that.. :blush: I thought i'd been to the beginning. Thanks.

[Shifta]

LoL... Hawk eye.. :woot:

[MattW]

Sanwa servos are a touch shorter between mounting holes than KO and Futaba, so it could be a little more tricky.

That said, I know Si Moss runs for Sanwa, and I think Grant runs a Sanwa servo, and I definitely had a Sanwa in my prototype car - so they can definitely be used.

I actually ran the plastic blocks (and steering cranks for that matter) at the last national of last year, and the British indoor open thingy the other week. In the face of it, they seem quite strong. I hit a car very hard down the main straight in my last run, which in turn fired the car straight into the wall at the end of the main straight. Blocks fine, wishbone broken!

[MattADH]

Blocks fine, wishbone broken!

I wonder where the weak point will be now what with the stronger wishbones?
I know I used to bend hinge pins and have stress marks on the alloy 10-degree blocks after a large impact...

Interesting, I'll do some measuring later I think between my Savox and Sanwa!

[Dazzler]

I wonder if there will be additional holes in the 'stronger' rear wishbones for the rear shock conversion? They're not on the photo's of the prototype car on Schumachers site - maybe something for production?

[David Church]

They had them on the new wishbones I saw a few weeks ago at worksop:thumbsup:

Re the plastic blocks, do they replace the shims for doing toe in etc. on the rear?

[MattW]

Mikey, tbh I don't know as I didn't fit the rears. However, I suspect they will follow the same approach as the Mi4 ones.

These have toe molded into them, so if you want to make it wider, you use the same shims front and rear. If you want to change the toe you just add/remove shims from one end. Yes this does potentially put some strain on it - however, in plastic, this isn't an issue.

Sounds simpler and you now also have toe in on the hub with the new alloy hubs

Looks like a new chassis listed on the parts section, so it's basically virtually a new car :(

Cat SX with stiff chassis for £150 anyone :(

[mikeyscott]

Interesting, I'll do some measuring later I think between my Savox and Sanwa!

Just taken my Savox out of my B4 and it fits the Cat SX much better and lines up nicely, the Sanwa is now going to go into the Cougar SV or maybe back into the B4 and I'll order another Savox.

Seen the cost of the big bore shocks etc. That'll be £80 for them, ouch...

I reckon selling the Cat SX for £150 would be a better option and then getting a new one....

£60 for the Cat SX2 springs! You're having a laugh!

[purplenut]

These prices sound to my crazy,do you think the prices will drop and its just to get us to buy the new one?
Hope not as ive always been failfull to schumacher.
And would like to hop up my sx,as ive done with lots of my schuys.

I have already asked them if they are doing an upgrade pack and no was the answer.

Time to think about what I'm going to do as I understand the new chassis is different to the Carbon stiff lipo edition.

[purplenut]

Hmm giving me something to consider to....

[mikeyscott]

Need some more close up pictures of the back end mounts and chassis please!

[Mossy]

You shouldnt need to do too much wiht the plastic hangers in terms of adjusting them with washers. The brackets are moulded to my standard geometry i ran last year, so prob only require the odd washer etc to suit you.

Si

[Snappy]

Does the new CAT provide enough room for today's high capacity lipo's?

My only real gripe about the SX is I have to be carefull chosing batteries that fit under the belt and pulley.

Cheers for the info.

Is the chassis different to the updated LIPO chassis that became avaliable on the Cat last year?

Is it worth selling the current car for the new Cat, or is it just the big bore shocks to really get?

Looking through the parts list on the Schumacher site it does look like a lot has been updated.

Can't see it changing on that front

[Rookie]

What an exciting time for me to get back into R/C guys !!!

Was a bit costly discovering my old cougar 2000 in the loft & relighting the fire !

[frogger]

My CAT SX was the best car I ever had. Been missing it since I sold it so I will definitely be getting back into 1/10th with a new Cougar SV and a Cat SX2. And just in time for summer too :thumbsup:

[Titch]

Tried to find some of the big bore shocks.. Schuy's out of stock, Apex and Modelsport doesn't recognise the part number.. :(

Anyone know where I can get some from?

Cheers

Could be wrong but I don't think they are out yet to buy??

Ahh.. cool, just with it being in Schuy's site and having "out of stock" next to it, I just assumed I'd missed the first rush :lol:

[lochness42]

schuey had only shock bodies/caps and bladder in their system marked as in stock - no pistons, shock rods and springs

[mikeyscott]

I see a number of parts have become available. I have purchased the new wishbones :) for my Cat

would like to know what the fab thing is listed under transmission and on the exploded diagram.

Just would like the new shocks and hangers now please! :)

forgot to order the rear alloy hubs :(

[mw02veg]

I will show you it sunday

[MattW]

It's an adjustable one way for the front layshaft.

[mikeyscott]

It's an adjustable one way for the front layshaft.

Yup Mike showed me :)

It's like the XX4

[MattW]

Not technically, the xx4 is a clicker unit, the FAB is a one way roller bearing that you can adjust. The general feel is similar, but still a little different.

I know they are technically not the same, but the principal?

[mikeyscott]

A few more parts for the SX 2 in stock and big bore pistons also now there.

Also noticed that they've got rounded pistons coming too.. Ooo..

[mikeyscott]

Anyone seen or heard anything further?

[mikeyscott]

Wonder if this will hit the shelves this week ?

[mikeyscott]

Anyone know if the Cat SX II comes with or without tyres?

[lochness42]

Anyone know if the Cat SX II comes with or without tyres?

I'm quite sure that without - as Cougar.

[cbcjcgreinke]

I wish 4wd was still populart hear, I miss it.

[mikeyscott]

Have they dropped the titanium turnbuckles on the SV and SX2 as they are gold, where as the original SX were purple titanium?

[SteveB]

Any update on the release date?

[mikeyscott]

Wonder if it's going to be a Friday release like the SV?

[mikeyscott]

Just been told it won't be until the 26th May until these arrive.

[frogger]

Freakin hell! :(

[mikeyscott]

Freakin hell! :(

Indeed - I hope I'm v wrong.

Got my SV to work on and my orignal SX so it's not too bad

[teamxray]

there hoping to release them next week so i have heard

That's what Schumy told me last week when I called and asked. :lol:

[mikeyscott]

Any more updates before my mate goes and gets another B44... he NEEDS a car

[frogger]

Schumacher started shipping them to shops yesterday. Still waiting for the call from DMS for mine but I think they are officially here. :thumbsup:

[mikeyscott]

Not what I've heard.

I can offer PR training.... ;)

Hope so as my mate NEEDS a car for this weekend's TORCH event.

[teamxray]

got my sx2 today

[gazhillAE]

Not what I've heard.

I can offer PR training.... ;)

Hope so as my mate NEEDS a car for this weekend's TORCH event.

Ive got a mint B44 for sale if he wants it for the weekend if the cats not out?

Going in the classifieds today

[mikeyscott]

Noticed that there is one in the For Sale section
