Awesome chassis.....mind if I copy it...?

[68Caddy]

Thanks for sharing those photos Akitani. Love the top one myself but I would take either one.

Haruki- Ju-go-nen mai ni Nihon de sunde mashta. Demo ne, "surata ka" wa nai desu ne? Ahhh, forget it... totemo nihongo wasuraimashta! It's great to see that D3/Retro is alive and well in Japan. It would have been great to find a slot club while I was there. I did race at the Tamiya facility in Atsugi as I lived near there in Ebina. All of the R/C racers where so nice to this gaijin and gave me lots of help with equipment and my language skills.

I would like to buy a kit even though the $ is so weak. However, it would be nice (kimochi-iie) to have a slot car from Nihon.

Gambate!

Super-clean job on that F1 chassis.

I'm always impressed when guys make the extra effort to put that
extra bend in on the front axle support for some more surface area to solder to.

[j-slot]

Thanks everyone for your evaluations.
I will test Hanada F1 kit car on this Sunday, though I think it needs more flexibility for the better run....
Anyway, I'm happy if my cars will be useful for your scratchbuilding.

Hey JJ,
I bet this chassis would work real good.
.062 brass all around for weight. and some great pan movement ideas.
Great axle support front and rear.

Matter of fact!
I may copy one for myself!

[John Miller]

Very nice work. How did you make the pin tubes on the F1?

[Greg VanPeenen]

Very nice work. How did you make the pin tubes on the F1?

Looks like 1/16 brass tube inside square tubing

Akitani, Haruki, Kamo and Hanada,
Absolutely SANO looking cars in every respect!! Thanks for the photos! Hope things are getting better in Japan.

LOL looks very kool Brian. I love there motor brackets. And i will bet they are all square and straight.

[One_Track_Mind]

my guess is this is a JK F1 bracket, no?

[JerseyJohn]

Yup. I should have said the brackets in there Can am kit. Check out the post. They are nice and thick...

For Can-Am Kits, finally we have .032" thick and .047" thick brackets.(1 inch wide)
For F-1 Kits(proto-type), presently brackets are .032" thick.(3/4 inch wide)

According to Hanada-san, for Can-Am, .055" and .062" thickness is possible but for F-1, maximum thickness is .055".

Personally, I would like to try .047 or .055 thick brackets for F-1 & Can-Am.

I will let you know if we could supply motor-brackets as separate parts.

The photos that I posted seem not to be displayed.
They might have been unsuitable to the purpose of this topic title.....
Next time, I will repost them to another topic concerning Tokyo D3 cars.

Akitani,
The pictures of the cars were there for a short while but then just disappeared!! The Surtees Lola was made from a Ferrari body I think! Great idea and great looking stuff!!

Today, Kamo brought ready to race D3 cars at our Tokyo D3 meeting held at Cheerio SpeedWay, home of Gerding King G13.

Five Porshe 908 RS are built with Hanada D3 Can-Am chassis kits.

With a .032" guide-tongue and motor-bracket, each car weighs around 103 g, 8g lighter than what I built with a proto-type kit with .063 tongue and bracket.

I tested a white and green cars for shake down.

The both cars broke 4.6 after 7 or 8 laps on Green.

A Honda F1 with a spare body of Lotus 56 Indy Turbine car is made Kamo for Miyamoto, who will race on our first F1 race on May 22.

Built with Craig Carreia's IRD F1 chassis, the car hit 4.56 on its 6th lap on Green.

I will post some more detailed photos of the Porshes later.

Another set of photos is a proto-type of Hanada F1 motor-baqcket.

It is made with .063 inch brass sheet, so thick that inside walls interfere with motor-screw holes.

The final thickness will be .047" and we are thinking of getting rid of the third bend for bracing.

The final shape will be a standard bracket with a separate brace plate(.047), like a JK D3 F-1 Chassis Kit.

I have reposted the pics on another thread "Tokyo D3 cars gallery". Please refer to there.
Thank you,

Here are some more photos of Tokyo D3 Can-Am Chassis kits.

A green car has a shorter length between a guide-post and a rear axle, compared with a white and other cars.

The price of a RTR car is set very low to attract prospective D3 racers here.

Kamo and I are talking about the next five RTRs.

They will have Ti 22 Short bodies with the same Hanada chassis but with thicker motor-brackets of .047" thick.

Hanada-san and I agreed on the final version of Can-Am motor-brackets.

.047" thick with slits inside a bracket for inner rails(up to .063 wires).

Good Racing,

Haruki

Haruki,

Please let us know when (if) those .047 brackets are going to be available for purchase as a separate part. They are VERY nice!

How far apart are the rails if they are soldered in the slots on the inside of the bracket?

Hi, Dennis,

Hanada-san is going to produce the motor-brackets as separate parts soon.

Keith asked Paul about the D3 legality of the Hanada Can-Am chassis kits and their components.
They are now D3 approved, so I am looking for the best way to make them available to D3 racers/builders in the States for the benefit of D3 racing.



The outside width of the bracket is 1 inch.
The thickness of the bracket is .047 inch.
The inside width of the bracket is 1 - (.047 x 2 ) = .906 inch
If you use .0625(1/16) wires for rails soldered inside the slots, there will be .906 - (.0625 x 2) = .781 inch(19.8mm) between the rails.

If there is any more questions about the kit and its components, please feel free to contact me.

Ditto. Copy that H man

[slotcarone]

Haruki these are really nice chassis and parts. Are the brackets made for Hypoid/offset motor?

Mike,

Check out post #10. These brackets have identical offset to the JK brackets.

Dear D3 and Retro racers,

I called off the test day for our Tokyo D3 Can-Am chassis because of the violent earthquake having hit the north-eastern part of Japan.

Our D3 racers and my track is all right, but I had a couple of things to take care of relating to this disaster.

Now I am building a Hanada chassis kit.

My first intention is to just build it as it is, but i cannot help "tuning" it because the kit has a very high potential.

I ground off some "meat" from the original motor bracket, reducing its original weight of 9.5g to 8.7g.

It would be easy for me to reduce it less than 8.5g but I stopped at 8.7g to leave an extra strength of the bracket for expected bangs by novice racers.

I also ground off some brass meat from the guide-tongue's lead -wire retainer.

The guide-tongue itself is so meaty that there is a lot of room to lighten it.

I have just finished soldering the main parts of the chassis: nose-piece/guide-tongue/motor-bracket with two rails of 062 and 055.

I am going to install bat-pans and a tension bar to finish the building.

I am going to post a picture when I finish building and testing the cars sometime next week.

Haruki

I forgot explaining the weight of a Can-Am motor-bracket of .047 inch(1.2mm) thick.

It is 7.1 g compared with 9.5g of .0625 inch(1.6mm) thick version, mentioned in the above quote.

A 047 version has a good balance of strength and lightness.
