Tamiya TRF417
 

Pictures! :)

Maybe time for a new thread for the 417 now that we know the car is coming and the first pictures are published in Japan...

2012 season???? That's soon:weird:

Looks like a 416 with the lipo kit, whats new?

Following Tamiya's naming conventions, i would be EXTREMELY surprised if they tried to pass that off as a 417.
More like a TRF 416 WEXYZ

No that's more marketing stuff!
They said: "Ready for the 2012's championship"

Look closer...

From the TRF Twitter feed:

"TRF417 integrated motor mount, the new ball differential Center, 19T, and adopt a common front and rear bulkhead. Battery Center has received outside the motor."

So, 20 years after the Avante, Tamiya decide to bring the centre diff back to electric!

EDIT Maybe I have misread the specs...

About the Item
-The chassis design is focused on weight distribution and high-traction characteristics, with *the new
maximum chassis weight rule in mind. *The 2012 world championship regulations state that the Max.
chassis weight will be restricted to 1,350g. (1,450g in 2010).
-The TRF417 has an optimized chassis layout for high-power lithium batteries and brushless motors.
-One-piece aluminum motor mount offers extra strength and durability to handle high-power motors,
enabling transmission of the motor power to the drivetrain with minimal friction loss.
-Compared to the TRF416, the motor position has been moved about 2.0mm towards the center to keep high
traction during racing.
-By using a 19T pulley, the secondary gear reduction becomes 1.94, which is very close to the ideal rate
for brushless motors (2.0). With this, the car has less flexing resistance on drive belts and speed loss is
minimized when the throttle is off.
-Newly designed steering linkage is not connected to the upper deck, providing improved flexibility to hold
traction during cornering.
-Newly designed ball diff housing and plates provide extra durability.
-Identical front and rear bulkheads.
-Comes equipped with short reversible suspension arms and TRF416 uprights.

Newly Designed Parts
Front/Rear Carbon Damper Stays
Front/Rear Aluminum Bulkheads
Aluminum Motor Mount
Aluminum Center Shaft
Aluminum Diff Joint
Aluminum Steering Arms and Linkage
Diff Plates
Wheel Axle
Cross Joints
19T Pulley
Carbon Lower & Upper Decks (thicknesses TBA)

Wonder the Yoks & 3Racing already started to copy it for 2012 BD7 & Sukura Zero 2...:D

OMG I remember buying my Avante from Beatties in 1988..still have my Futaba 2LGX and original CPR unit all boxed somewhere, awesome gear..I had forgotten all about them until your post...waaay too long ago

hope to get more pictures on the 417 soon.:nod:

That 1-piece motor/center-shaft mount would be worth a pretty penny! :eek:

Well that was a let down.

I remember looking at your 416X Experimental chassis. You used the the front bulkhead on the front and rear, as it looks like they will be doing with the 417. My questions is (without having my car in front of me) do the front bulkheads bolt onto the rear with the standard 416 mounting hole positions? Or did you customize that with your chassis?

Just adding the larger CAD pics to this thread....

They mount to the upper deck perfectly and place the diff in the same position as on the 416X. But you need new holes in the lower deck for the bulkheads and also suspension blocks as they will otherwise hit the bulkheads.

On the 417 all these parts appear to be new though.

It's interesting that Tamiya is making the motor mount beefier while other maunfacturers are making their smaller, even to the extreme like the CEFX Evo(Yikes!). I like Tamiya's approach better cause there's less worry about tweaking the motormount in a bad crash.

:D Steel mate ;)

Um, the CEFX Evo motor mount, although small, is made of steel, not aluminum. It would probably bend or break the motor screws or the screws holding it to the chassis before anything else.

I know it's steel. I was only using the CEFX Evo mount as an example of how small the mounts were getting. Actually, I would be more worried about the motor case/ends getting tweaked in the event of a bad crash.

Imagine what that would do to the electronics when the motor smacks into them.

man jus when i pick up a 416x and lipo chassis this comes out...:lol: oh well guess i'll have to wait till DEC for this:sneaky:

More on the 417 @ http://kentech.blogs.se/ and http://www.tamiya.com/trf/ :sneaky:

Some interesting info on the ideas behind the changes from the 416 to the 417.

Glad that I didn't pick up the lipo chassis..... gonna have this one thou!

Looks like a narrow ta05ms. The bulkheads are the same. Obviously the motor is even more central to the chassis, but it seems to also be placed more forward on the chassis than the 416x like the ta05ms.

Hop new ball diff can be use with 416we or 416x

Yes me to.Lucky i didnt buy the new lipo chassis im Interested on the new balldiff!!

I just picked up a lipo chassis Monday :lol:

Are you guys really that surprised? Tamiya comes out with a new car every year, same as Xray. :blush:

Looks very promising. I like many of the changes and of course all of the top touring cars will likely have lipo chassis' after this year. After running my 416WE without the steering brace that connects to the top deck for the first time this week, I can see why they are ditching it all together. Really made the front end come alive.

79,800Yen, I see tamiya are trying to give yokomo some competition in how high to price a car.

FYI the TRF416X was 83,790...

I'll wait for the next model of it, just ran the new LiPo chassis on my X for the first time, wow it made a difference from the Demon kit I was using. Wasn't happy i have to start using tape for my batteries again tho.

Missing the brace above the steering, too much flex for me, and too easy to tweak the top deck in a hit. The chassis looks identical to the X LiPo chassis, maybe a few different holes. With the motor moving forward, weight coming away from the rear of the car means less rear grip.

415 to 416 was a big difference, 416 to 417 not much of one, almost the same amount of changes as the 416WE to the 416X, should just name it 416XX or something like that.

I would think that the 417 is designed more for lipo than 416 as for those who had that need to upgrade their existing chasis to a more lipo friendly one.

I don't think that moving the motor towards the center will reduce the rear grip as the weight of lipo compare to the older batt makes the car overall lighter so I think that move will not effect that much.

Having a solid motor mount does transfer most of the driving force of the brushless motor to the wheel.

Only my opinion.

Tamiya car kit had mmore discount !

.

415 to 416: new upper and lower deck, all bulkheads new, new motor mount, new diff, new steering, new damper stays, new layshaft, new belts...

416 to 417: new upper and lower deck, all bulkheads new, new motor mount, new diff, new steering, new damper stays, new layshaft, new belts...

;)

RC MARKET, which model are you refering to ? 416x or 417 ?
Looking forward to own 1. Tks

Wonder if they will release it with something like the Spec-r gear (Tamiya made version). I was expecting to see it on the 417...........looking fwd to this :)

They mentioned newly designed ball diff for TRF417.
