Schumacher CAT SX3 1/10th Competition 4WD
 

Schumacher Racing have announced their stunning new 4WD 1/10th off-road buggy - the new SX3, an evolution in the design of the hugely popular SX buggies that saw the team return to off road competition. The new car features a revised drivetrain that sees the motor move to a true mid layout.

The new CAT SX3 follows on from the highly successful CAT SX range. Stronger and more durable than ever before! An all new mid-motor design with central lipo battery positioning offers fantastic balance, control and agility. Jumping like the Pro's is made super easy with the new compact layout and corresponding motor/wheel rotation. Awesome acceleration and straight line speeds are still achieved.

With the inclusion of the excellent large capacity big bore shocks, high down force MAX sized rear wing and new cool body the CAT SX3 remains the market leader.

Designed to race, designed to win! The CAT SX3.

VERY nice:drool:

Nice car but i hope it comes with decent turnbuckles not the ones made of carrot:lol:

Just got to love that. Very nice.

I like it, it has the old 90's shell styling to it.
Looks like it may be able to be a conversion kit too? for people that already have CAT SX's. Should be cool to see how it handles compared to the original.

looks good nice shell too well done schuey looking good

The CAT SX3 looks ace...looks like it has a similar chassis layout like the CAT 3000. Very nice to see a mixture a new and old designs from Schumacher. :thumbsup::thumbsup:

Looks very nice :) liking the new shell with through air vents , no more bendy wing mounts or snapping o-rings :thumbsup: Can't believe they haven't addressed the front bracing of the front hingepins ;);)
Looks good though. Just waiting for the usual backlash on more new stuff coming out !!! Bring it on i say keeps everyone on there toe's.
Well done shui i say :)

Typical, buy a Second hand SX2 off Ben 2 days ago and Schumacher release the SX3!!!!!!!

There’s no justice :(

Hope they do a conversion

I think the biggest improvement is the shell now covers the whole car instead of stopping halfway down the side :D

Wow, very nice :drool:

Seems like R/F bumpers could be suitable on Cougar SV?

Yeh reminds me of the XX4 shell.

mmmmmmmmh nice. :blush:

Very nice infact!!! I also spot beefed up rear arms so no more random breakages. Still dissapointed no alloy arm holders like the sx1, so theyll be needed as a hop up. IF I didnt have a new 4wd coming very soon id definately buy one cos I loves my cat!!

not entirely sure why the price has gone up... I know it's a recession, but it's a replacement for the SX2, I assume. I would have thought the price would have remained the same

The whole car reminds me of a XX4 the layout is only slightly different but the 3 belts is the clincher. It should be very good on track i bet.

Slipper looks better with the pressure spring on the plate's instead of the other end of the shaft. Looks a lot neater. :)

3 belts, does remind me of the XX4 as well.

Also does it remind anyone of the original BJ4, then the worlds edition.

The Original Bj4 was stick pack, then the worlds was saddle pack.

Worlds year as well this year, so I'd imagine a lot more manufactures will have new kit in the works.

MiCk B. :-)

Any word on release date etc?

There better be alot of compatible parts witht the sx2, otherwise I'll have a sh!$)(&*D of extra parts!!!!

A conversion kit would be the best.

Looks like a well thought out car it has to be said. Shell is a 1000% improvement on the original too.

Be interesting to see them go and as Mick B says I bet there are a few revised cars in the pipe line from all the big players.

Anybody else looking at it and thinking "British TRF511"?

When the sun comes out dave "Due Spring 2011"

In all honestly I think the only bits that changed have been the chassis, top deck(s), 2 belts, the centre trans housing (I bet the internals are pretty much the same) and battery straps.

The rest looks exactly like the SX2. It's almost like it should of been called the SX2.1... The complete front and back look exactly the same apart from finally they did away with those stupid rubber bands. After I snapped 3 lots in 2 race meetings I superglued it all together and never had a problem! The new mounts look an easy upgrade to any SX1/2 though.

The 'upgrade' parts for the idle gears also put the slipper adjustment on the spur side which gave a much better feel rather than all or nothing which I found happened a lot with the older system.

The centre housing now runs on 5mm bearings instead of 4mm, which IMO is a big upgrade :thumbsup: Which means new slipper shafts & plates too I think. There's also new rear lower housings to match.

Unfortunately I don't think a conversion kit would be economical as it's mainly the expensive (alloy/carbon) parts that are new, but thats just my thoughts.

Looks nice, IF they bring a convo kit out, with a few very rough sums I have just done:blush: lookin at the NEW! bits it has listed on there site and working with current prices of chassis ,top decks and shortish belts etc for the sx2 I recon the convo should be £150ish. Not bad makes me feel better about the second hand cat I have just bought:lol:

This is if Schumacker do a kit......Might see pound signs and hope we spend a fortune on getting all the indervidual parts needed,or hopeing we all shove our SX's in the parts box and rush out to buy a new kit:eh?:

I bought the sx as I have a load of stick lipos.....have to see how this goes

Tom beat me to it. The lower rear bulk heads are totally different.

So is this car a vast improvment, a must have!?? or is it a diffrent style than the sx2, as altho it looks diffrent, there is no cutting edge reinvent the wheel stuff here, as has been said...looks like an xx4/BJ4 worlds.

If schumacher are saying the sx2 is not as good as this car, why bother with the sx2, could have saved us a few quid and brought this out before, saddle packs have be arround some time.

i ask Tom this as he is one of the most honest team drivers I have met:blush:

Thanks Schumacher! Made my decision between selling and keeping my Durango now!
Schumi it is!:D

Yeah they're only 5 years behind the times now :p

It's good it's being evolved and (potentially) improved though. Is anyone else thinking if it had a single front belt it'd pretty much be a CAT 3000 re-release?!

So trishs rear gearbox housing wont fit the sx3 will it............

I can see why they've kept the front the same, but if they were designing a new car, why not go with a twin belt layout rather than 3? odd.

BUT, personally I think a conversion would be a BIG seller. All the people that have just bought CAT SX2's for the new season don't now want to be going out and buying another new car. Plus all those on budgets who have bought second hand CAT's. It will appeal to lots of people if they produced a conversion kit for around £150ish.

Probably cos they didnt think that the TRF511X would win the first 4 nationals and then the euros in 2010 !!!!

Belt configuration seems like a lot of effort just to get the motor rotating the same direction as the wheels. I'm sure there is more to it than that. Looks like a nice set up though.

Lets hope it drives better then the 3000, that handled like cabbage:p

I'm certainly interested in pre-ordering one

I like my original SX and it's early days with the Durango...

S1 maybe, but with the titanium turnbuckles and alloy

Schumacher did the plastic ones, as the alloy ones caused so many bent screws. Plastic also with its flex will make the car feel soooo much better then the alloy did... So, plastic is the upgrade!! ;)

Has it raced anywhere yet and when's it's first meeting in the hands of the team? EPR this weekend?

I miss my SX, so time to return :p

wow was jusr weighing up which buggy to buy one of my main considerations was stick or saddle as wanted to run same in both 2wd and 4wd so cat sx2/ cougar sv were high on my list as i have a large selection of stick pack lipo already and both run stick out of the box not anymore though so its either sell on all my stick lipos and get saddles and conversion kit to run saddles in the cougar looks like a stonking kit though
best thing is was going to order sx2 2 weeks ago but due to birth of daughter have not had time to get to shop to order it lol think it might wait till the new one comes out now

What's the max LIPO height in the car as well as I'm due to get some new LIPOs for my SV and was going to get saddles - prob Nosram. Have to have locating humps
