My eyes are fine Bender. The sketch you provided is exactly what I'm talking about for this car to work and yes, it's been done and no, it didn't work for anything above a toy level of power. The spur wouldn't be easy to change/remove, a slipper clutch wouldn't fit into all of that and that still doesn't take into account how the front and rear diffs would be driven from that high up.

Why don't you just admit to everyone that you made the CAD drawing.

I have to say that the "white line" in the CAD looks more like a shaft to me. And this car still looks more to be on the fun/"toy" side <_<;

If you look at the end of the "White Line", you can see what appears to be a drive cup. The driveline looks to be lifted off a TA-01/02/Manta Ray

It looks like a shaft to me, but instead of mounting the spur and slipper to a shaft driven by the motor they are driving a conventionaly gearbox and using the shaft to link 2 seperate gearboxes like the Ta02 or manta ray.

If this is a real *NEW* design then it would appear that they are planning on releasing both a 2wd and 4wd drive cars with the 4wd being a 2wd with a 2nd gear box added to the front and a shaft to connect it the existing rear drive.

In tamiya speak just think of the FF01 (fwd) and ta03(4wd)

I got the drawing off 4wdrc.com - so no, I didn't do it

I frequently ran 10turn motors in my old Top force with NO problems! The car was a bloody missile too

It's also very easy to incorporate a slipper clutch into a combination spur gear/bevel gear arrangement - Tamiya did that in the 80's (remember the Avante )

The 80's called, said they want their technology back...

I don't buy it. I think this is a drawing somebody that doesn't work for Tamiya made for kicks. Tamiya is a company capable of designing a World Championship touring car in either belt or shaft drive and that design is just not up to that level. It contradicts the demand of the market for 4wd cars which is greater durability and more simplicity/ease of maintnance. I think Tamiya can do it, just not with that complicated a shaft design.

Losi just did a prototype 4wd based on the JRX-S but there desige routes the drivetrain around the battery. With the battery in a side by side configuration it would be a heck of an obstacle for a shaft that runs from the rear gearbox to the front gearbox.

This is a tired old comment used by people who have little idea of design philosophy and the origins of the current trends in todays rc cars

Try looking at any relatively new rc car and you can see many new ideas that are just old ideas. In most cases the only difference is in the better quality of the finished product, hardly surprising given the advancement in manufacturing technologies.

The Japanese off road Nats is probably the most highly-competative 4wd arena in the world, and last year 2 old Lazers made the A-Main. By your logic any old car should be completely uncompetative.

I would like you to list all the design improvements in off road over the last few years - I certainly haven't seen any?

Your point is? The Losi 4wd was just something they did to test a few ideas, and it didn't exactly work the greatest. BTW have you seen a Durango - the shaft runs over the cells - it might be a pain but the car works.

IMO the cad drawings just look a little TOO close to Tamiya parts/ideas to be somebody's rip-off, plus the fact that the chassis seems to fit very well with the body they tested it with.

Hi Bender. Thanks for posting that sneek-peak.

It does indeed look like shaft drive. An arrangement similar to the the Top Force. Love the overall parts layout though. It's hard to tell from the pic, as it's quite small and a great deal of the parts haven't been modeled to enough detail, but I doubt they would have gone to such a refined layout for an entry-level machine. Notice that the shocks have also been located inboard.

It's funny with regards to the topic of no new ideas in R/C. If you look at the Avante, which was unveiled at Nuremberg way back in '88, with its unconventional longitudinal motor/battery and transverse spur, you see that it took the rest of the R/C manufacturers about 10-15 years to adopt that now standard layout.

I happen to believe that Tamiya has better ressources than any other R/C manufacturer out there at the moment, and if they chose to hone themselves on a competitive off-roader, they should be a force to contend with. The success they acheived with touring cars may very well be spilling-over into other categories.

As long as they don't price it like their worlds winning touring cars I might be interested! Although this chassis from the small pics looks like a mid level racers, certainly no BJ4, but a huge step above any other 4wd buggy they have out right now.

Good to know someone else knows their history however, Sg's Coyote was in fact the first 4wd with that design, back in late 1985!
As I said before, it's the quality of the finished product that has advanced so much in the last 20 years, not the designs

Exactly right! Both Tamiya and Kyosho have the resources and the capital available to dominate any market they choose, and they have both proven it previously.

People just need to remember that the percentage of RACE cars sold is tiny compared to the BACKYARD BASHERS that these companies sell, and their previous efforts (Tamiya TC, Kyosho 1/8th Gas) have effectively shown the world that they can beat the best - when they choose to.

Tamiya's 415MSX sells for less than virtually every top level tc. It's cheaper than the current models from Yokomo, XRay, Corally, Hot Bodies, and Schumacher.

Sorry, but if you're not smart enough to shop around for a good price then that's you're problem.

Average prices:

HB Cyclone $425-$450
Schumacher Mi2 EC $415
Corally RDX $389-$400
Yokomo BD $400-$420
XRay T2 $390-$410
Tamiya Msx $360-$390

I bought mine for $349
