Hi,


perhaps you know my "sort of tyco jet" project :
http://www.hobbytalk.com/bbs1/showthread.php?t=247218


The main idea of it is to recreate the old brass pan magnetless chassis configuration, but with modern plastic cars (here, a tyco 440x2 widepan). The goal is to recreate the advantages of a brass pan :

-lowest weight possible
-very balanced weight, in wheels alignment



A friend of mine (Fred ) is working on a similar project, but with the tomy turbo chassis.


One différence is he created a "cage" to put lead weight into, to change easily the weight and allow fine tuning :

We see here how it works :

The car guide pin is modified to run on a 1/32 slot track (my friend has a routed h0 track project in progress) :

He tried his setup under 15 volt (with carrera evo standard controlers, don't know the ohms), with standard tires : he was able to run his car quite easily (on a carrera track...so the corner radius are wide ! ).

Next step, is to test under 18volt and parma eco, with silicon tires. But this set up is promising, according to him.


I think the "pan type" weight adding is somethings you should try. The weight is well balanced, and very low, and placed in the tires alignements.


If that slot car shape was good in the 60-70's, it should be good today...


I'll post news as soon as fred will inform me.

Very interesting desing and chassis setup Demether. Being that I raced magnetless 1/32 cars I can kind of see where you are going with this setup. The only thing I'd question is could you get the weight to be flatter and lower? I was always taught that as you stacked weight up from the chassis' pan or bottom you contribute that weight being added to the gravitational pull when you enter corners - in straight line runs, the weight is moving forward or backward (if braking), but when you hit a curve, the weight up high transfers through the curve's gravitational or G-force. I know there is not a ton of clearance below the chassis like in 1/32, but I wonder if there is some other place to displace the weight to keep it flat and as close to the chassis bottom as possible?

Just some thoughts and things to provoke the design thoughts. I think you guys came up with a great idea here and can't wait to see more! I loved trying to come up with the best balance and performance in weighting a 1/32 - doing in HO ought to be really challenging and fun!

I made the same thinking to the builder (I didn't built this car). I think like you : the lower, the better. But experiment can inspire some of you too.

For non magnet racing, I trust more my own setup, based on the tyco 440x2 wide pan. The weight is a lot lower than the fred's "turbo jet" :

If fact, it is lower today, because I received my new silicones tire, with a lower diameter. I'll post pictures soon on the dedicated topic.

By the way, I 've got another project for cheap but eficient h0 magnetless racing....to make teasing, I can say I didn't reinvent the wheel...I 'll post the result soon too.

Great work from over on the other side of the pond Demether. Can't wait to see the newest experiment.

Dimitri,

Yes, that's what I was thinking too! I see you have figured it out. How does the lower weight car handle compared to the first post you have show us here? I'm wondering if it changes much, if anything.

Didn't reinvent the wheel? So then what did you reinvent (or invent)? :p

PD2:thumbsup:

The tyco car (last photo) is handling very good with it thin silicone AJ's tires. the driving feeling is between a really good magnatraction and a stock rubber tires magnet tyco 440x2. (18volt).

For now I'm waiting for the slide guides I've ordered, to complete the car. I received the final tires I'll use (super tires 0.442), but the cars stay in the pits for now.

To pass the time, I'm working on the lexan bodies I'll use for this racing class. I'll have to finish the chassis mods too (make clean and glued weights, install tubing for pin mounting, clean everything, round the tires and the sharp edges of it to allow sliding).

The only unknown thing is the slide guide : When I'll receive it, I 'll be able to know what type of front end I'll should use, and if the slide guide is an improvement or not (today the chassis with the typically short tyco pickup shoes stop easily in case of big sliding).


For the next project, once I'll complete the "plastic pan warrior" (I've to find a better name than that or "tyco jet"...), I'll work on an hybrid plastic-brass magnetless chassis, quite similar to a tycopro or superII (it's why I didn't reinvent the wheel, because the concept exists)...but on a tomy turbo base chassis (number 8 chassis...I 've read that is one of the best...lol). I 've got chassis, I ordered some brass sheet. Now, everything is in the hands of royal and US postal ;)

demether ,
very interesting to follow your work . Keep it up as i love seeing new stuff and ideas.

I' m impatient to make some advancements, but for now I'm waiting my supplies orders !

Well keep us all informed as inquiring minds want to know ! Another video down the road would be good too !
