New Dyna Storm Parts

Recommended Posts

As most of you know I have commissioned professional engineers to make some improved parts for the DS. It is expensive and the engineers are professional R/C and real car plastic specialists. I am doing this for my special project race DS. Since alot of people need to replace their broken parts and more parts made means lower per piece costs, I will be making batches and the parts will be for sale.

All the parts are optical lazer measured from the originals, computer stress testing analysis is made on each part, and I have also provided broken parts for the engineers to see where the breakage typically happens. In addition to the laser measuring, each part is hand measured and drawn to cross check.

Finally, a complete 3D model of the DS is being made; part by part so the whole car is disassemblable and can be analysed on screen. It's a really COOL thing to see on screen, and it's super exciting for me every time I am at their office to see the car on screen being spun around and flicked and unbuilt at the press of a button/mouse ball control thing ;):lol:

The front D part, rear arm mounts L&R, a modified copy of the rear metal strengthening cross-bar to fit in front of the front D part, the complete front base plate/bumper piece, and some other bits that I will mention later.

I will post up screen shots from the CAD program so you can see what is coming.

Shots of the improved front D part. (not complete yet)

Extra material where the shock tower mounts. The rounded part.

Interesteingly the engineer pointed out that the standard part is flat because reduces the manufacturing cost, and the square divot outcut in the std part that weakens it at this point is there because that is where the molding started/finished.

View with the three new top side strengthening additions. Triangle against the vertical, 2 new ribs (will be on both sides). The pin tube will be the same size as the pin, removing the two copper flanges. This reduces weight, and spreads the load across the part - which is a large problem with the original where the pressure was on the two edge areas thanks to the flange. The plastic material is being considered for least friction. More on this later.

What you cannot see here is the underside which also includes strengthening modifications to the L&R edges.

:lol:

Anyone have a pic of the stock part to compare? Now I have to run home and take apart my DS and look!! :)

Where were you busting your bulkhead? Or were you bending hingepins?

This is great. Is there any eta on when these parts will be available?? Badly stuck for a pair of rear arm mounts L&R from the D parts tree. Broken 3 rights and 1 left so far! Brushless power really kills these things.

Are you planning to make the suspension pins fit without the brass collars? That would be a plus!

The brass collars is something I had initially decided to delete and make it the pin size. However the friction issue is unclear. The engineer knows a plastic type called X10 which is harder than teflon but has the same low friction properties. So we have decided to stick to the orig size hole and change the cooper bits for a full length tube insert of X10. This way it is easier to sell the part as it can be used as is with the orig brass parts, or the X10 insert can also be provided.

Here is the almost finished part. Attached to another new part - a new base plate.

The D prt

1. The L&R sides are totally revised with strengthening ribs,

- there is more material above the pins (the top surface plane) then before

- the round nut holes have been replaced for hex shaped nuts (to avoid the same issue as happens on the rear mounts), the thickens of the part has been increased slightly for further strength and to allow a totally secure fit for the nuts.

- the stopper lip in front of the top deck has been thickened as this often cracks off

- the the 2 tabs on the rear, pushing against the back of the suspension tower has been made into one continuous lip

- the bottom of the plate also has strengthening changes made, while still remaining as hollow/lightweight as the original.

I will get back and under images to post up.

The bumper-base plate

2. I have added 2 ribs below so that when it lands there is less friction/drag as only the 2 ribs will scrape.

3. the front bumper lip has been reshaped to allow straight screwdriver access to the suspension tower screws (inaccessible with the orig design)

The engineer is FANTASTIC!!! Comments welcome.

Update -

been a bit busy with real work things lately. But the D PART PROTOTYPE PARTS HAVE BEEN MADE ! :):rolleyes::lol:

They were made using a prototyping plastic 'printer' during a batch of parts being made for 'a major mobile phone company' ;):P

The Engineers are SO COOL! saving money!

It took over 9 hours to make the parts. The 'printer' builds the parts ONE MICRON layer at a time. It is simply Awesome technology!

the parts are EXCELLENT. Light and MUCH stronger.

I will get some picts and post them up.

The final molds are now being made from the prototype parts, and the first production pieces can then be made and test run on my hard used race car.

The engineer loves the DS so much now, he presented the project at the Mech Engineering Institute conference last week! :D:P

The first production parts have been made!

:P :P :o

I am away at the moment, but this week I will return and post up pictures and work out prices.

The uprights are available from Square and 5 stars in alu. Hence I am not making these in plastic. The Square parts are better - they are lighter and better made. I have both brands front and rear uprights, and have compared on very accurate weighing scales.

The Square cost more and are definitely better items

Improved D parts anyone? ............. :P:D

Test Ready! :P

and the rears!

We initially had some vacuum moulding issues with the parts and it has taken many reworks to establish the ideal injection points etc to produce parts EXACTLY to the designs. No ugly sprue marks or injection run off marks B)

  • The 3 items are all lighter then the original, are carbon-plastic hybrid mixes, and are XXtimes stronger than the original items (I will post up the exact numbers after on track-road-ramp testing is completed, as we may play with the plastic-carbon mixture).
  • All the materials are sourced direct from manufacturers in SWITZERLAND.

Yes, alu was considered but rejected, for the following reasons:

  • Tamiya designs the orig parts in plastic to absorb shock and vibration. Changing to alu means transferring these to parts not designed for this. I have already seen chassis cracked up from use of homemade alu rear D parts.
  • The carbon hybrid parts are lighter then alu ;)
  • Ther carbon hybrid parts are stronger! than alu in direction of load. Alu parts will BEND long before the carbon parts will give. B)

The fixing points, angles, toe, etc are IDENTICAL to stock as previously mentioned. I am running my car live with these parts now and will post up photos.

The prototype engineer is a PERFECTIONIST and he refuses to take photos of the parts because he is not a 'professional' photographer. !!! :rolleyes::P

but I have no such qualms so will be taking some photos of the parts myself and will post them up next week!

Parts fit standard Tamiya hex bolts B)

And another BEEEEAUUUUUUUUUUUUUUTIFUL part we have developed:

I have 3 made already but here is a screenshot for now!

feneklap_lexan_01.jpg

A FULL EXACT FIT undertray, allowing you to remove the heavy chassis side plastic edging, fully seal the chassis/shell, and protect your base plate.

Especially nice for those who have or want to have a real carbon chassis (yes, you can ask..... B) )

And ofcourse, the new front D part has been specially designed with an under slot exactly the right size to slot the underguard into, so that no dirt can get in from nose diving under breaking or on landing. :PB) B)

Made from REAL LEXAN, comes complete with overspray protection film.

:rolleyes::P;)

Oooh, the undertray looks sweet! I'd definitely be interested in one of those if you plan to produce them.

Thanks guys, it's a fun process and the parts are super!

The lexan underguard is ready for sale now. I just have to work out the price. I am also making some other lexan parts for the DS so we make full us of the cnc and lexan machines which keeps the price low as possible ;)

one of the other parts being made in lexan is my personal DREAM DS part...........................................................................

the GEAR BOX COVER!!!!!!!!!!! :o:):lol:

it has already been made and I am carrying it with me everywhere in love with it! Sheding loads of weight and letting you see the gears. THIS was how the whole project started for me! THE part that started this whole improved design and rebuilding. I have been just desperate to get this made after seeing it had been made for the TRF211x all those years ago.

And now we have it!!!!!!!!!

photo and prices soon :) :)

Well I'm definitely in for the undertray. I was this close to building my own vacuforming table just to make one of these. The exposed chassis plate is the only reason I hate running my DS. I've gone through ridiculous lengths to protect it. Try 5 layers of masking tape + plastic sheets held on with servo tape...

Singapore959, How does the undertray attach to the standard car? Will it use countersunk screw holes like the Top Force?

BTW: I'm still convinced that a newly designed rear bumper lower mount that creates a lower control arm brace would REALLY help the rear suspension survive. The problem is that an impact pushing forward on the rear arms (shown in red) causes the lower control arm mount screw (blue) to oval out the chassis plate screw hole (green). A brace (purple) combined with that tiny lower bumper mount would really tie that rear end together just like a modern touring car with their interchangeable toe-blocks...

This is already done :P

I can't give away all my surprises until the car is unveiled! ;)

It's been made in 0.8mm CF, so weighs nothing and looks beautiful. Same with the existing one infront of the gbox.

Note : due to playing with the wheel base I have made it more [ shaped (rotate that 90deg to the right) so that it can be placed fore or aft the arm/cooper bushes.

A show of hands would be good for people interested in the lightweight gear cover.... :D

My hand was up a long time ago. Singapore would you consider offering all these new hop-ups in a package deal as well as individually? Don't tell us anymore of your secrets, I want to be surprised. :)

If it's in one piece with the undercowl, that would be cool!

Looking forward with anticipation to seeing the 'full package'!
