Tamiya TB Evolution V
#1232
I've had my Evo V for roughly a month now and for the last week or two I've had some breakage issues
I do hit things a lot, so I do expect to break stuff ( and a TC isn't exactly the most sturdy form of RC car around..)... but I was hoping it would be a little tougher than it has proven to be...
The more troubling breakages have been the front bevel/ring gear and a stripped spur gear. I'm not sure how I stripped the spur gear (in one of the crashes, perhaps??), but I don't want to do that too often since you need to dis-assemble a lot of items to get to it and change it...
I was wondering if you could use a 48 pitch spur on it instead....if so, which make/model would be ideal? Perhaps the 64 pitch gears are simply too fine for the abuse I put the car through
Also, I was wondering if there were any aftermarket sets of bevel/ring gears that would handle an impact a little better. I have a couple of spare gear sets in my hands now in case I strip those again.. Getting to the bevel/ring gears isn't a hard task, but getting the e-clip on and off the end of the driveline can be a little frustrating...
The car seems to handle fairly well and the quality of the parts used seems pretty good, but I've found that I spend almost as much time maintaining it as my old Losi XXX-S, which seemed to break regularly..... Fortunately, the Losi parts that broke were normally A-arms and other suspension pieces that could be quickly fixed between heats....
Any thoughts?
Maybe I should have got a belt car???
I'm racing in 12th scale for a while until I figure out how I want to tackle these issues with the touring car....

You can use 48 pitch gears, the maximum "safe" spur gear to use is 73 tooth. Any bigger than this and the spur will hang out the bottom of the chassis and has the potential to loose some teeth if it hits anything. As for the bevel gears stripping, what i did was try to put more shims on the bevel gear side of the bulkhead, instead of the shaft side. I do this so that it pushes the bevel gear further into the gearbox causing more surface area of the gears to touch. Using this method i havent stripped any gears running stock.
Hope this Helps.....

Hey Evo 5 Guys.....I haven`t read any good news about the Evo 5 in awhile because My computer was(is) down.
I`ve Raced My Evo 5(using a 19-Turn Peak Dynasty Motor) a few times and it runs well. . . . .But it isn`t better than My Pro 4 Hara Edition.....No Shaft Drive Kit runs better than the Pro 4(My Opinion).
-You can Run/Drive the Pro 4 Hard/Fast with any Fast Motor. . . . .I don`t think the Evo 5`s Gears can handle a Motor faster than 19-Turns.....?
-The Evo 5 has good Steering; but not better than the Pro 4.
-I thought the Evo 5 has a better Ball Diff set-up over the Pro 4`s; but I was wrong. The Pro 4`s Ball Diffs are Smoother. --The Evo 5`s Ball Diff are good because they are Aluminum.
But overall the Evo 5 -WINS- because of the Easy Diff Access.....The Pro 4 kills me when it`s time for a Diff Rebuild.....Ha Ha!
Who was using a Evo 5 in the 2007 Reedy Race?

Hy there !
I run my Evo5 in Stock 23T and 17T and i have also no problems with the Gears.
For the spur gears i have to say that i always run 48dpi spurs
At the moment i have a 71 Spur in the car with a 25T pinion. this is a gera ratio at ~1:6,66.
An other question.
I have a few questions for a good tarmac setup.
I ran the dampers with 40 oilt 3 hole plates, and the yellow springs,
Chamber 1,5° al around, 4° Caster, 5-5,5 ground clearance, and the soft swaybars front and rear. toe in behind is 2,5°.
The damperpositions,and the shims under the upper arm mounts are all like in the manual.
Now my question. Whats about the rollcenter on tarmac. have anyone testet shims under the suspension blocks ?
Many drivers using 1mm up on tramac (with oter cars).
Please if anyone have tested it out, let me know.

I've had both the EVO IV & V. I think both cars have some good and bad points to it. The EVO V is lighter due to the lighter bulkheads, but I think they are way more trouble to work than on the EVO IV. I also think the EVO IV was more durable than the EVO V. However, when it comes to a lower center of gravity, adjustable ackerman, and the parts the EVO V comes with, I think you get a little more for your money and a more race worthy car. Personally, I like both and if you can get a good deal on the EVO IV, I would suggest going that route. Our LHS has been selling the EVO IV for $275 out the door, so a lot of guys are buying that.

I don`t know about using Spacers under the Suspension Blocks.
-I only race on Asphalt and I feel it`s all about the Tires and Shock Set-Up.
You don`t really need Hop-Ups for the Evo 5 unless you just like to have everything on your Kit(like Myself).
-Titainum and Aluminum Screw Set
-Titainum Coated Shock and Suspension Shafts
That`s about it for performance part help.
The Pro 4 and Evo 5 are somewhat the same.
-The Evo 5 has better Diff Access over the Pro 4.
-(to Me)The Pro 4`s Diff Ring Gears are Stronger
-(If you`re in the U.S.)Tamiya Parts are hard to get.....Tamiya USA only.
-The Evo 5 doesn`t have a Spool.....yet. You can drive Harder and Faster with a Spool.
I read that some of you guys haven`t had any problems running a Fast Motor in your Evo 5. -But; check those Ring Gears and Bevel Pinions after a few(2) runs with those Fast Motors. . . . .You have Wear on those Gears.
-The Evo 5`s Ring Gear(s) Teeth are Much Smaller than the Pro 4`s.....Meaning not as Strong. . . . .I`m not taking a chance.....Ha Ha!

I haven't driven the 415, yet, but I have a friend that has raced an EVO III Surikan Edition, EVO IV, and TRF415 Marc Reinhardt Edition. Since our track is small and we are only allowed to use the Tamiya Sport Tuned Motor, he said so far the EVO IV has performed the best. However, if it was a bigger track and larger motors were allowed, he thinks the 415 may be better. The main reason for this is because of the better throttle response/punch from the shaft drive vs. the slight give that belt drive cars tend to have before hard acceleration. Other than that, he likes both cars just for different applications. However, as always, the driver is definitely going to be a big key in performance. Just to give you an idea, one of our racers used to race in Japan and he does extremely well with his EVO III Surikan Edition. The only problem is that the diff gears of the EVO III have some reliability issues. I'd say if you buy an EVO IV/V or TRF415, you would still be buying a good car.

My Evo V has been handling very erraticly and I found out why... the front wheel was wobbling enough to hit the steering arm on the hub assembly. After changing out some parts, it seems like the wheel itself was the culprit... I'm wondering if certain wheel brands don't fit the Tamiya wheel hubs quite right??? Or is this a normal thing when you hit stuff a lot (I have had a few brushes with the wall ) I added some spacers to help if the wheels do wobble again... but I'm curious to find out if there's a way to keep this from happening in the future....????

i had this problem once, as soon as i changed the wheels they were fine......sometimes if you hit things it can bend/buckle them. The only way to fix this is to change to a different brand of type of tire to see if it works better for you, and of course try not to hit things.

hi everyone
well I bought An EVO 5
Are there any good build tips i should Know(besides spend a long time shimming it right)
also a friend has been experimenting with the bevel gears, he reckons that if you dont grease the gears it will lessen wear. Because less dust and little rocks/sand wont get stuck on them.( i race on a very dusty track). so grease vs non grease?
Any help is appreciated

You will get split references on the grease part. Personally, I would grease it because under load, the grease helps protect the gears, under the conditions I am using the car in (parking lot racing). Dust and dirt does get into your bevel gears, but that's why you must clean that when it builds up in the car. The main thing that will damage bevel gears the most is crashing.

I run them dry and it has worked well running stock. One thing I would do is to open the top gear covers after every couple of meets and blow/brush off the dirt that gets in.

How well seal is the gear box or cover on the EVO 5? Is it completly sealed or is it just a simple cover. I run on dusty parking lots and my yokomo LCG SD eats gears like crazy, since its diff cover only cover half of it...
BTW, does anyone where I can get an EVO 5 online? Some links would be great.

The seal on the evo5 is just a cover.
The evo5 does not eat gears very often, even though dust does get in. Its just you have to make an effort to keep the diffs clean.

Evo5 Spool Update !
Hy there.
For those who are interested to fit a spool in your Evo5:
The Evo 4 Spool from Tamiya will fit with a little mod perfectly in the Evo5.
The problem is that the gap between Ringgear and the beavelgear is to smal.
It works, but it dosent run smooth.
You have to sand of about 3-4 tenns from the aluminium part of the spool where the ring gear is attached. Then there is enugh play at the gears that they run so smooth like the onway does.
A second little hint is to use the 415MRE spool outdrives. They are more durable as the black ones from the Evo4 Spool.
I will look if i can make a picture of it, and post it here.
