Default 1/32 Direct Drive Slot Car

What do you think about this concept?

I posted this earlier.

These cars interest me more than plastic model cars.
I would like to try one on a Carrera Track.

Hard to imagine it working as well on tracks with short, say less than 15', straights and also long straights over 20'. I'd also like to see it with front axles and wheels that look more authentic, at least in 1/32.

Would be interesting to try one out and see how it compares in performance.

Default This idea is nothing new

But JK is a leader in commercial slot racing and I commend them for trying to make a clear vacuum bodied blob look like something resembling an actual CAR. These are fast enough to maintain speeds that are probably 5 to 6 times what is a scale speed for 1/32 or 1/24 scale models. Oh, I'm sorry. these aren't models. These are blobs. But when you can't see them anyway because they go so fast, who cares? Sorry to sound like a fogey but years ago (like 50?) the commercial blobs and their rip snortin speed demons knocked this hobby out of the hands of the intended consumer and it will happen again. It just gets out of control. Dag nabbit, Whipper Snappers!

It is nice to see JK trying to make a better looking lexan bodied car that is reasonably priced. I personally like the hard bodied, more scale looking cars but at least these don't look like a door stop with a high dollar motor strapped under them!

Really, the only thing new here is the motor. After all these years it is hard to believe that someone has designed a motor that doesn't require gearing. One that developes 8 to 10K rpms with the torque necessary to push a slot car

Way back we used Pittman sidewinder motors in vac formed corvette bodies...they worked really well..of course they were tanks...and probably over scale by a big margin..

RacerX -

The body shown and "many" more (32nd and 24th) simillar have been available for years, both painted as shown and clear.
While not true scale, they are far from the "door stop wedges" many hate.

The new chassis...interesting concept. Many 1 to 1 electric cars are direct drive, or at least have no gear or pulley (belt) multiplication.

In the 60's/70's many Nitro drag racers were also direct drive.

Agreed, and the sticker kits that JK has are wonderful. I have used them successfully on other makes of bodies. With a bit of creative "re-sizing" here and there to fit slightly more scale proportions, they make for really nice-looking cars.

Exclamation RE: Direct Drive

I entertained the idea of doing this in 1/32 and then 1/43, but Someone else pointed out (and correctly I think) that, most motors don't have enough torque to accelerate quickly without gears and if they do they suffer in the braking dept.

It all came up as an option to me when Hot Wheels re-introduced their Sizzlers line a few years back and I noticed they were direct drive. Yes, they take a while to get up to speed.

Clearly the "trick" to a car like this is low weight and low drag!

Absolutely, the motor is the new and important bit.
From what I read elsewhere it's a standard motor case with standard size (2mm) shaft fitted with "a bazillion turns of wire." Apparently the Chinese makers of those motors will wind them any way you want as long as you order some tens of thousands of motors.
Normally more turns of wire means thinner wire - there just isn't room on the arm for a lot more of the same size wire. Look forward to seeing how they've managed it.

Yeah, I was throwing rocks at the more open class cars with the high dollar motors and winged, door stop bodies. Don't get me wrong, I've run the wing bodies and have participated in some Retro events with lexan so I'm not opposed to them, I was just stating that I personally like the hard body, plastic chassis cars with more detail and slower, closer to scale speeds. I recently was in a new, local slot car shop and was admiring how much better some of these J&K cars look than the lexan bodied cars I ran long ago. I may race some in the womp class if they get enough of a group to race.

I will simply withold my opinion on this until I have firsthand information.

If it works as advertised, it could provide a paradigm shift in our thinking.

Sorry, I don't see this as a viable commercial success, except for certain tracks that suit the motor's torque/RPM characteristics. One of the best reasons to use gears is so you can tailor the cars power characteristics to any particular track by simply changing gears. Oh, and I don't see this working very well for Formula cars either. Paradigm shift? Not so much.
