I doubt it. Even TB designer is racing the 415. If there is going to be an EVO 4, Hara would've been driving it.

We'll see have to see how many different cars that TRF is going to bring to Reedy Race next month.

Btw, who's going to drive their EVO III at the Reedy Race? You guys haven't given up on the ol' shaft driven car, have you?

Default removing bearings from oneway

Has anybody successfully removed the one-way's bearings before?

Can I just press them out or is there something else fixing them in?

Will ther be an EVO4...you bet!

Historically, the manufacturers let the shops "know" when a new car is to be released in the Japan market. Depending on the pre-orders totals, the "first run" of the car (unit numbers) is evaluated and production begins.

From the apperance of things you have two design teams at Tamiya currently...415/Tech Racing/Tamiya & EVO/Tamiya TRF.

I for one will run the EVO at the REEDY race next month

Sorry Fab, but GFX is right- they are working on the EVO IV right now. They know the EVO III had the potential to be the faster car, but was never perfected. The EVO IV will be their car for the IFMAR Worlds. They are hoping to have it out by then.

I honestly believe if they do the car right and learn from the mistakes on the EVO III they can have a car just as dominant as the TC3. Of course, even if they follow through and perfect the EVO III, they'll still never stay on top because they hardly have an American racing team. I can't see how they expect to do well in the American market when they have a skeleton racing team and little or no factory racing support. HPI is just as bad. If the car is fast on carpet, then it can be made to go fast anywhere. Look at the TC3.

What mistakes do you believe they made with the evo III that might be fixed in the next generation?

I just finished rebuilding an EVO-III that I acquired.

I must say that the car's drive-train is smooth out of the box ... smoother than my TC3 was.

Anyway, I notced that there are 1-zillion posts about this car on here, however, before I pilfer through all these, does anyone have any immediate tips for the car?

I will be racing it indoors with rubber tires, and a stock motor for the next few weeks before the weather allows for some outdoor mod racing (with foams). The set-up I am using is from one of the Team Tamiya drivers here in Canada ...

Anyway - I look forward to running this thing this week.

Spend 10 dollars and get the new lightweight shaft immediately. It is 2mm longer than the stock one and will help avoid stripping your front one-way and bevel gears in a crash.

We do not know at this point, but this is what I am assuming:
*Gearbox design and build quality of the plastic. The original TB EVo III and SE have soft (not brittle) plastic. Racers wanted it to be as hard as TC3s
*Battery positioning. Everyone wanted it to be closer to the middle like TC3 so it's more balanced
*front One-way design. According to the peeps out here, The new lightweight shaft seemed to fix it. So we'll see
*Slight chassis/suspension upgrade. Any extra adjustments that were not available on the current cars will be redesigned and incorporated into the new car. For example: new, thicker main chassis and new shock tower on Surikarn Edition compared to the original car.

Bigdog: If they indeed want to use EVO 4 as their ultimate car, that means 415, in Tamiya's opinion, wasn't ready for prime time yet, am I correct?

That's one prediction that I have on it.

The other one is that Tamiya wants to show the world that Tamiya can (and already did in european championships) win with a car that is easily recognisable as a Tamiya car (being shaft driven etc)

It will be nice if Tamiya can win one for the shaft after the belt. Which means it will be the ONLY company to win with TWO kinds of drivetrain!

As far as buying TB Evo IV, I don't know. I still haven't got the chance to buy EVO III yet. My EVO II is in rumble and My original EVO is up for sale. I just don't have time to race regularly these days.

If there are some cosmetic changes only with the EVO4 in compare to the EVO3 I think you wonīt need buying this car. There are some things you can do to the EVO3 and itīs nearly perfect then.
My EVO3 basically is an originally EVO3 not a Surikarn Edition. But I changed to the aluminium upper mounts when these were released. Also changed to the new rear shock tower some time ago as the position for the rear body posts is better.
Regarding gearboxes I changed to the Square gearboxes and they really are worth the money. No graphite gearbox will be as good as the Square parts. Perfect shimming and better support for bearings and screws.
As for the oneway Iīm using the Jürgen oneway and this is perfect again. I will look forward what Tamiya is doing with the EVO4 in this area.
Regarding chassis Iīm keeping with the original 2,5mm chassis as this is very stiff already using the aluminium gearboxes. In fact I removed the plastic chassis brace between lower and upper deck as it was to stiff already and I think itīs working better now. Beside this lot of German EVO3 drivers are using the 2,5mm stock chassis with their Surikarns and not the 3mm version as they experienced the same thing being faster with a little less stiff chassis. But Iīm talking about rubber tires as there is no racing with foams here.

I donīt think Tamiya canīt do anything much different to the battery position. Maybe a little more to the front but Iīm not sure if this will be better. I think you canīt move the battery closer to the middle more than 1mm without shortcutting the battery as itīs very close already. Maybe with changes to the drivetrain. But I think weight balance is very good for a shaft car and you can do this even better with additional lead weights at the right side of the car. I have to say itīs way better than my TC3 in this area and I canīt tell of any torque steer problems currently.

Overall in itīs current configuration itīs my best touring car I ever had and itīs paying off in race. I was winning all of the last 4 races in 27T stock with 2 TQīs and 2 second places after qualification. After removing some initial problems it never let me down and is as strong as my XXX-S was. No compare to my TC3 braking easily rear arms and shock towers when someone hit me. At saturdayīs practice it was the first time for me breaking an rear arm in nearly one year of use. But this was when I hit a curb at full speed on a superfast track and crashing sideways into a wooden barrier at the end of the straight. I think my TC3 maybe would have ended in a puzzle in this situation.

Are you kidding? Do you realize how many people sold/refrained from purchasing the EVO3 because of the oneway and diff gear problems? Not to mention all the people that were deferred from considering the car because of all the poor press on drivetrain? It was horrible. The car still sold well but it was only a fraction of what would've been possible sales.

As far as the improvements, I made it clear the car isn't good for carpet. That simply proves that the car isn't rigid enough or tunable enough.

V12- I understand what you are saying about the chassis. Keep in mind you are talking about less traction conditions than we typically race on here in the states. I'm sure you and the overseas guys are good drivers and good tuners so I'm not trying to degrade you or anyone else's tuning abilities. I realize that softening the rigidity is a way of tuning an r/c car, but I don't believe it is a correct way to tune. The TC3 is rigid enough for carpet and is still plenty tunable for lower traction conditions. It's harder to tune for less traction, but still possible. My whole basis for this comes from full size race car tuning and in 22 years of racing I have never seen or heard of anyone removing gussets, roll cage connectors or bracing to tune a car for a slick track.

My ideas for a better car: (off the top of my head- I have more)
- fix the drivetrain even if it means 2 or 3 piece shaft.
- THICKER SHOCK TOWERS- please, my Surikarn shock towers twist like mush
- wider front shock tower- need at lest one more hole to stand the shock up
- corner braces for the upper deck like the 415
- carpet upper deck option. less holes, 3mm
- graphite tranny cases (makes the car more rigid)
- lower the hinge pins and give me anodized spacers with the same footprint as the block to raise it back up when needed
- move the hinge pin braces and front bumper back 2mm. this will essentially move chassis and most of the weight forward 2mm leaving the bumper and front body posts in the same position relative to the body. you can still move the weight back with the spacers. I don't know of anyone or never seen a setup where someone had the arms all the way forward which tells me they are too far forward. We move the front arms all the way back and then sweep them back with the hingepin blocks to get the weight forward fro carpet.
- caster blocks with different caster options!!!! GEEZ, gimme a break. Is there another car on the market that only has ONE caster block and no optional blocks?
- rear hubs like the 415 in graphite and aluminum
- optional motor mount that uses the forward spur gear adapter hole on the driveshaft and moves the motor forward the same amount. Basically a motor mount with the screw holes moved back 3.5mm or whatever distance that hole is from stock.
- make the screw holes in the aluminum servo mounts differnt distances on top and bottom so you can flip the servo mount over and move the servo forward 2mm
- optional aluminum center brace(s). Please tell me why I have to buy soemthing like that aftermarket?
- fix the swaybar mounts where the waybars at least work a LITTLE without 10 minutes of adjustments!

Jason, I just want to argue one point with you:

Quote:

Maybe on foams, but it's a damn good car on rubber tires.

As far as an Evo 4, I wouldn't look for drastic changes. Remember, they now have the TB-02 as a similar platform to share parts with between the two. That took a lot of comitment to that overall platform. It would be interesting to see them abandon the plate chassis for a molded composite tub out of a similar composite as Stiffezell or something.
