V12 - I believe they are.

I think the only difference is their aluminium construction and 0 degree toe settings.

Never measured the weight of my 415 when it was new, and since our club racing there's no weight limit, it hasn't been an issue.

I just measured mine, and it's freaking 3.5 oz under weight that's rtr with body, stock motor, with original suspension.
The weight limit over here in the uk is 1500g, I always run the car too that limit (don't see any point running it lighter... it's only something extra to think come race day otherwise). Currently, I have to add 50g worth of weight to bring it upto the limit.... However, I have noticed something interesting though. With the LWT suspension on the car weighed 1501g... with the old 1513g. I'm guessing thats a gain of 3g per corner on the new suspension

(oh and BTW thats with HPI 1540's on 26mm wheels, with jb blue moulded foam insersts).

I do try and keep the car as light as possible though, the lead can be quite useful on getting rid of any tweak, and can be useful as a tuning aid. Plus any weight low down, will lower the CoG

Default 415 on carpet with foams...

For all you guys wondering about if the 415 is a good with foams on carpet...THIS CAR IS A MONSTER!!

It was terrible with the wrong set-up (as most cars are). But with the correct set-up, it is just plain incredible.

I am currently performing some minor tweaks to the set-up and will post it if anyone is interested!

I have always been slower when compared to the fastest A-main guys, at our track, by about .25 seconds. We race on Friday nights. While I did not race, I ran during the day. On Saturday, I went in to the track to check the laptimes and I was faster, on average of .1 seconds, than the A-Main guys that raced that night. I was running the stock belts and they were set extremely tight and my motor had 5 packs through it and I was using average batteries. Needless to say I was shocked as to how fast this car was and in the fact that my lap times are always faster when I race than when I practice. So my times should have been faster if I had raced.
But not only was I faster, I was so much more consistant with the 415 over my TC3.

My car is basically a stock 415. I have an aluminum front diff and locked center pulley. That's really it. Oh yeah, for added stiffness, I superglued 2 top decks together to help reduce flex.

I will post the set-up if anyone is interested!

I would stay away from the MS if you intend to race on carpet. You need the thicker chassis and the stock suspension!!

Jürgen Horn makes them. He makes oneways and spools for different cars and the front diff for the 415. His emailaddress is [email protected]. He is located out of Germany. Quality stuff...pricey, but the diff should last forever as long as you use the Corally Blades on the dog bones!

koabich: I remember reading about this diff a few pages back. I thought he had stopped making them cause the people were complaining about the aluminum wearing. Even with the blades.

If this in not true and your having luck with them, let us know. I will probably order a set. Why Tamiya has not made this part available is hard to understand?

Steve Wang mentioned before that he is looking into making aluminum diff halves for the car. Steve are you there??

To my knowledge, he still makes them, but I could be wrong. From what I understand, he made 2 versions: the first version, which used the EVO III diff rings (you were not able to use any blades with these) and a second version that used the normal 415 diff rings and were blade compatible.

In my experience, I ran 1.5 packs through the car with the diff for the first time and they showed very bad wear. I opened up the dog bone pin slots a little and started running the Corally Blades (from what I know these are the only ones that fit Tamiya dog bones correctly).

The second version of the diffs had the dog bone pin slots opened enough to be able to use the Corally bones without modification. He was also working on his own version of the blades, but from what I hear, they kept cracking so he stopped making them.

Since I have been using the first version of the diff, with the Blades, I have had no problems and the diff shows absolutly no wear (I have about 50 runs on it).

They are expensive though, at $75.00 for one front set (with shipping). The nice thing is that it uses all the same parts used to make the rear diff for the 415 so you are not piecing anything together...like a Yokomo diff.

I don't think he stopped making then because he just intoduced an aluminum rear diff for the 415.

If Speed Tech were going to start making them, I would definately support them and buy my diffs from Steve!

Yippie....

Finally I've had the tools at my disposal today (ie got my hands on my dremmel and special screw removal bit.... ) so I can finally use the body posts as a tuning aid...

I think I'm gonna try that along with spool and locked centre pulley at the next winter series round (hopefully Jan). I might even try it on thursday on indoor carpet, but I'm not to sure if thats completely wise

Can't tell you how frustrating it was reading all the chat about using the posts, when one of mine was stuck with a stripped (steel dammit!) screw head on the underside... hey ho, heres to yet more performance out of the 415

Anyway, I'd be interested to try a diff in the car, but I doubt I'll bother buying one.
Spools seem to be the front axle of choice over here at the moment, except on carpet where the one-ways come in (even then, on tight and twisty tracks the spools seem to work well).
I actually tried a spool in the car again at the weekend, and even though it was only a fun day (btw 415's are good at scoring goals in RC football, i got 2... oh and I won one of the musical boxes heats, just in the box in time), the car felt very good, with quite a lot of off throttle adjustability (which i like).
Just got to see how it goes on a proper track, rather than an oval, avoiding the ramps (they jump bad... nose heavy...don't ask how I know! )

Laterz
Ed

p.s. Yes I did wince when it landed....
