I bought this little RC12 recently. I'm pretty sure it's an RC12E, but on the body that came with it there are decals saying RC12EX.
Even with google i've not found out much about an RC12EX, can anyone enlighten me a bit? Or am i just looking at a standard RC12E.
I've stripped the electrics from it and i'm going to try and clean up the chassis a bit. Am i right in thinking the steering isn't standard? It had the steering servo mounted at the front, flat on the chassis, rather than mounted on the top plate.
I have a feeling the cars that sold in japan might have had letters after the name implying that there were different models with options like the countersunk chassis on that one and the grp upper deck? I know the offroad cars sold in japan with options and they all had letters after the name.

Car's weight saver chassis has been modified, radio tray may be home made?
Here's a pic of the decal :
Hi Paul

Funny you should mention that. When i searched for "associtated rc12ex" most of the pages that came up were in japanese, so it was kind of hard for me to get any info from them
A rc12 ex was a lightweight version that had the chassis lightened with the large front hole and the trumpet shaped hole in the center. The other features were the radio tray that was fiberglass with several holes and set up to have the resistor on the top drivers side,countersunk screws ,and hollow rear axel. your car looks like it was a ex, although the chassis has some extra holes and the radio tray is a homemade job.

Thanks
It's definately been modified a bit that's for sure.. At least the lightening holes have been done reasonably well. It also had cut down phantom front bumper fitted when i got it. I think i'll just give this one a clean up and try and find a suitable receiver to complete it.
Yes that´s an early Schumacher diff but maybe revision 2 or 3. I think there were some development stages even before they started using fibreglass and later graphite rear axle.
I still have the first steel axle from my Schumacher diff but it doesn´t have the hexagon machined also not the flat spot for the left hub set screw so I think it´s the first revision.

Yes the Schumacher diff didn´t use hub and wheels like the Associated diff and others but the Schumacher wheels actually were hubs and the tires mounted on sleeves were pushed over these wheelhubs.
This had two advantages over other diffs, first one you didn´t have to readjust your diff after changing the tires and you also could change tires in just a few seconds.
For fixing and centering the sleeves to the hubs there were some small wedges built into the sleeves. You can see this at the next picture.
The tires at the sleeves are supersoft tires covered with silicone what was used here for indoor racing at slippery tracks before the carpet tracks were introduced.

Yes Cecil Schumacher from the UK invented the ball diff and that was the start of the Schumacher brand also. The Schumacher cars were later.
I think I have an old RRC magazine with the ad.

That's the one I had, big hex and no flat spot. I thought mine was from about 1979 but the info I've seen about the Schumacher diff says it was released in 1980. Thx for the pic.
I think the diff i have may be a MK2 or 3 Schumacher diff. I'm sure i have the magazines with the adverts that might show the differences too. I don't think there was a long time between the design changes either so it's hard to tell.
If i find the adverts i'll post them up, i think i have the advert/reviews for the early XL and C cars too.
I had a lot of 12e parts from ebay lying around and found a chassis but it was drilled and rough. Decided to build a pin router and make a new g10 chassis. Here's some pics
Pin router. Bit sticks up the height of the NEW part, the overhead pin...

Those are what I was referring to, they well them retail as Roto-Zip branded parts.
I was fortunate to find this at a garage sale a very long time ago. I did go thru it about 7 years ago and serviced the diff cleaned the bearings and dressed up the motor. It is a runner.... although I don't run it.
I've had this for a while now, i was going to try and restore it, but i might just sell it as i have to many projects and not enough money, can some one please let me know what these are woth now
Cheers Rob

very nice 12E you have there.
what rc on road had the straight front axel? it looks like a minature rc10L with an aluminum straight front axel.
What straight/aluminum front axle, pictured above , are you talking about?
Is this an rc12E, or just a clone?
I kinda like the look of the body too: any ideas what it is?
I'm considering to buy this. Do current wheels and spurs still fit, or should I upgrade to another rear axle for that?
Just got this car in from the Netherlands. I know it's a weight saver, but unsure if the chassis has been cut out more or if it actually came that way. The front bumper almost feels like foam and is very flexible. It has a light weight metal diff...

I'm not worried about the chassis as it's rough anyway. It's the perfect time to make a copy of it. I'm in no hurries either so you can take your time.
You can use .125 Plastruct from Tower Hobbies for bumpers and radio trays. This is what I used...
