Hey all,

Having a small issue with my 12scale.

Running tekin RS with 17.5 tekin
Novak Booster
Reedy 1cell lipo.

I ran 10.5 and it ran fine, I switched to 17.5 and after about 3 minutes, speed decreased and motor became super hot.

I changed my tekin settings to what others were running and also changed my gearing accordingly.

I changed the Tekin and booster and even the motor same problem

Has anyone had this issue before, could my battery be faulty or maybe I missed something in the Tekin software?

thanks

Either too much timing, too much gear or both.

If you check the Tekin website--you can get a LOT of settings for different setups for your 1/12 car. I had nothing but trouble trying my car w/ 13.5 motor on 1S until I used some of the suggestions off the website. Now the car's ballistic---motor stays cool--and I can run 9 minutes no problem---so a little warm up time and an 8 minute race are a no-brainer!!
FWIW

bodies
 

I am really trying to understand this 12 scale thing. Can anybody tell me the effects of the different bodies. ie more push, more steering, more speed, more downforce.Are some just for pavement and others for carpet etc.

List of bodies would be:

AMR 12
Speed 12
Speed 12b
EE1
Speed 8
Speed 8 HD
CRC Bomb er

I would also assume mounting the body forward or aft would make the same changes so would it be fair to say most bodies are mounted to center the front wheel and the rear wheel position would change with the wheelbase.

In my experience.
17.5 is so slow, that traction is not an issue
So i don't see the point in dragging a body with more downforce around the track than necessary, such as the, CRC Bomb er or the AMR 12
For Mod, or in situations where traction is low, more downforce makes sense.

At the ROAR On Road Nationals in practice, I drove an entire lap at Full Throttle with 17.5 boosted, just to see if it was possible.
It wasn't my fastest lap, but it was surprisingly easy to do :lol:

For Stock I like the Protoform Speed 12

and the BlackArt Audi

for mounting, i just try to place the front tires centered.

the AMR and Speed8HD have more rear downforce and less steering than the speed8EXP and CRC R8 (closedcockpit)

i havent' tried the EE1, or speed12's.

for spec motors on carpet i prefer the speed8EXP or R8. the extra downforce AMR or HD might be useful for mod carpet or maybe even stock on loose asphalt?

all things equal, on carpet i would 'prefer' to use a harder rear tire (2xpink vs yellow/grey) and a looser body as opposed to a highdownforce body that locks the rear end.

mind you the last race i ran an AMR body and yellow rears, because that was the best arrangement for me that day. another consideration might be durability, a lightweight Protoform equals a heavyweight Parma in terms of weight and durability. a lightweight Parma needs reinforcement to match my driving style.

2006 front end is in fashion again ?
This looks like the best A-arm design of the "new tech" so far.
Throw some pod links on this and you've got a sweet ride eh.

There is no upper arm in that design though...the king pin is solidly fixed to the A arm so it will have a lot of camber change and no caster adjustment. Best A-arm design of the new tech in my mind is the new BMI front end :)

That was Corally's new car in 2006 and David Spachett won the worlds with a prototype of this car that had the 2006 Associated 1/12th front end which later became an option for the kit. The front end in the picture posted was the original front end which did not work well. They also offered a US version that had the standard 1/12th rear axle so other 1/12th wheels could be used as the original version could only use the old Schumacher wheels. These cars where updated and rebadged Schumacher cars.

1/12th community, correct me if I am wrong.

Sorry to correct you, but:

These cars are certainly not rebadged Schumacher cars.
They are genuine Corally cars from the Netherlands.

The original wheels look a bit like the old Schumacher ones, but they are
different.

It was never badged a Schumacher, but...

The Schumacher C car used that style of front suspension in 1984, the first time it was seen on a 12th car. It was a great car, and won the European Champs in 1985 and 1986 - over 20 years before Corally did the same thing in aluminium. And lets not forget that CEFX did the same thing with the C12 in 2004!

Corallys have always been Corallys, and they sold at their best when driven by one David Spashett, who won them their only two IFMAR WCs. David has retired now, and Corally sales seem to have retired with him! It is also worth pointing out that David was soundly beaten in the 2005 European Champs using that front end, but wiped the floor with everyone at the 2006 Worlds using the same car with an Associated front end - 'nuff said!! HTH :)

I made a national A final with that front end, 3 days after I got sent the car ;) I then changed it for an AE one over night and made the A again the following day with an L4 front end!!

Got a feeling that the FE that DS used in Gran Caneria wasn't exactly the same as the production one - I think it had shorter lower arms, and was worse!! That said, were it not for a servo issue, DS could well have won a euro champs with it........ Maybe that wouldn't have been an indication on the car though :sneaky:

The C Car definitely had that style of front end, I had one! Earlier version than the one in the pic though, stick pack version. Worked pretty well as SlowerOne has described.

Time moves on though, and the dynamic strut front end is definitely a better solution. Time will tell if the double wishbone front end will be better still.

That front end is basically what would be called a "swing arm" suspension in the big car world. Anyone that knows anything about the rear suspensions on VW Beetles, Auto Union F1 cars and Corvairs knows all about the problems with such a design.

I figured that would be a good conversation piece :sneaky:

I still have an SP12G sitting in a box, always thought Corally made very well built cars.
