Must be honest, never drove one competively. That direct drive, instant speed and minimum moving parts is simplicity at its best. Would totally rule out lipo

4-motor drive, 4-wheel drive TC.

Basically the design will call for one motor per drive shaft.

In place of a single large 540 motor, connected to an elaborate array of belts, pulleys, etc... driving two ball-differentials, you place two small opposing motors in the middle at each end of the chassis, replacing the differentials and gears.

Since all 4-motors will be connected to the same speed control, the speed control will know the exact rpm of each, and be able to adjust simulated differential action. You can then program the speed control to alter differential characteristics.

Now this would bring centrally located weight distribution to a new level, all right down the middle. Additionally, almost all drivetrain inefficiencies are negated since the motor directly drives the driveshaft and wheel. No more belts to replace, no diffs to rebuild, and no extra weights to balance the chassis!

There's your answer. Lipo for 1/12. Can you imagine the run times w/ a 13.5?

getting to the cost point that only ppl with a little more money than normal can race.
ya theres cheaper stuff and rtr but for ppl that have been doing this for a long time they want to race at a somewhat mid-high level and wont be able to and stop.


or


we are all going to run offroad and TC and 1/12 will die again.
wait isant this happening already

Rick, was the traction control system you referred to the simple system of amp limiting on the speed controls? Or was there a system that measured wheel speed from other wheels and adjusted throttle input based on that?

As long as Lipo/Bl is my future I'm happy.

You could program the front two motors to act like whatever diff options you'd want. You could shave the rotate at the same speed (spool), independent of each other (diff), or have no brake off power and same speed on power (oneway). The technology is here to do it. Good idea.

at the track i race at FASTCATS the wall are soft,

but the outer wall is like nascar, you hit you feel it from the drivers stand.
but it has to be this way.

Just because i am a glutton for punishment, lets talk cooling. ROAR allows no holes in the body yet, TCS offered a radiator and coolant...why didnt this system take off? From what i have read, the cooling was substantial. Items like this lend a bit of "realism", and performs a function. Any other innovative ideas/products out there that never "quite made it"?

There was something like that available years ago, but it didn't involve telemetry, it was an on-board electronic mixture control that optimized the fuel flow via an on board processor and an exhaust temperature sensor.

Worked pretty well too, as I recall, and very simple, it just basically tried to keep the temperature as high as it could as it was explained to me.

Well BX. I have thought about it. I'm not sure whats next, but I can tell ya what I would like to see next.

Pre liquid masked bodies. Then you could just cut out a design and paint it.
I think that would be cool.
