TM4

[hotrodchris]

Ran the TM4 for the first time today at Maritime, what an awesome bit of kit, so easy to drive straight out of the box!:thumbsup:

[AmiSMB]

Have to agree there. Am looking forward at getting it out doors to see how it performs.

[Lee24h]

The front and rear ends look very much like the xb4

[AmiSMB]

There are ideas from the XB4 in there as well as the Durango and AE B44. The wishbones are the biggest I have seen on a 10th scale car.

[B0tt0mline]

So how does the car perform?

[AmiSMB]

Me and three others who had driven Durango DEX410 and XRAY XB4 were very impressed with the kit straight out of the box. I am sure with more races under our belts and playing with setups we can the really see what we can get out of them but as I so so far initial impressions are very good. I had my XB4 standing by just in case but felt I did not need it. I am looking forward to doing more races and seeing how it performs outdoors. Trouble is I hope the weather gets better for that!

[hotrodchris]

Personally unlike many cars when you put the power down on a slippery surface the back end tries to break away, with the TM4 you didn't get this it drove straight out of the corner, the track layout didn't have any large jumps to really see how the car behaved in the air, but like Grant can't wait to get the car outdoors on a greassy Astro track and see how it performs under those conditions.:thumbsup:
But with a first outing and box plus guess work setup, couldn't have asked for any more, especially as I do not race very often indoors, was very impressed with the car.:thumbsup:

How does it peform compared to the Losi 22-4?:woot:

Thanks

[dMITIj]

Could ppl put up some pictures? :)

Thanks
Not having run the Losi 22-4 I couodn't comment, but with the different abilities of the 3 drivers using them on Sunday at Maritine and all of them being the first run ever with the build only being completed earlier that week, I would say they performed very well?:thumbsup:

[mjbtaco]

here are some pictures of my TM4 and my setup for outdoor clay tracks. It is extremely easy to drive this car hard. Very planted and tons of steering!

Here is some pictures of mine along with the setup sheet from the weekend.

How dith you get your 19mm ride hight at the rear?

[B0tt0mline]

Any more news on the performance of the car?

How stiff is the car?

[hotrodchris]

How dith you get your 19mm ride hight at the rear?

We were all 3 running 19mm by adjusting shock oils

[hotrodchris]

Any more news on the performance of the car?

Will No more tomorrow after running outdoors on astro but they looked and felt good without any noticeable lift of a rear wheel on high speed conering

[marcel]

We were all 3 running 19mm by adjusting shock oils
19mm by adjusting oil?
Please explane more about that:)

[hotrodchris]

Lower the weight and the car sits lower but still rides well I ran 40 front and 30 rear with standard kit pistols

[B0tt0mline]

any more news on the tm4?
experiences? :drool:

[AmiSMB]

Will be able to let you know more after I race again on Sunday outdoors on Astro which will probably be damp to start and then go dry.
With the rear springs being so long all I did was to have no spring preload at all so the adjusters were at the top of the shock. This meant that the car was around 19mm which was fine. Changing the oil does not really change the ride height. I would expect that if you put more rebound when you refill the shocks then that will change the ride height. I run with hardly any rebound in my shocks. I will be starting with 32.5 Losi in the front shocks and 27.5 losi oil in the rear on the kit pistons and standard springs. The flex can be altered like on the TM2 by cutting a slot in the upper rear top deck.

[fastinfastout]

have you guys come from the T4 v2/v3 as for comparison?

[marcel]

Way more steering and smaller turning circle
Easy to drive and more durable more easy to wrench on.
Nicer to see .
So allll great:)
T4 v2/3 is still a great car but tm4 is a whole other ballpark:)

[hotrodchris]

Ran mine on astro last Sunday with no changes except the ride height and the car was superb,really predictable, possibly a little bit loose on the back but very drivable, with it being a very quick turn around between heats didn't really get a chance to try many changes,but all in all very impressed and can only look forward to the next run and more time to adjust the setup.:thumbsup:

[hotrodchris]

Sorry should have added that started on ballistic greens track dried very quickly so changed to Schumacher yellows, loads of steering even had to trim spikes off as had superb grip and steering.

How does it feel compared to your XB4?

[hotrodchris]

A lot better, the back is alot tighter and i thought that the XB4 was predictable and easy to drive the TM4 has gone at least 1 stage further and as yet only 2 runs in have not tried to do any set up changes.:thumbsup:

At Maritine I ran both cars and with the TM4 i could bring the power in on the slippery sections whereas with the XB4 if i did the back end was stepping out on me?:o

[fastinfastout]

so this car runs 14mm hexs?

I'm sure my durango 210 runs the same size hex on the rear.

not sure about durango 410 fronts, whether they are 14mm as well...:confused:

has anyone run durango rims on their TM4? How is the track width, if any difference?

reason I ask is, I ordered a TM4 but not any rims, as I was in a hurry to order and got the last one at this particular shop in HK.

not sure why teamc went with 14mm hex's. I assume if I put the hex's from my T4 V2 that I can use AKA, kyosho, jconcepts and AE rims.

[hotrodchris]

I have been running XRay wheels without an issue, I believe you have to open the thread hole in the durango wheels up slightly for them to fit but believe that there is no issue with track width.

[AmiSMB]

I have re used my Durango wheels from the 410 to use on my TM4 and they are fine. I got some of the Team C hexes TU0440R to put onto my TM2 so can now run 14mm hex rims on the rear of that as well.

[DragonRider]

What oils are people running in the diffs. (Damp early morning to drying out dry Astro in the afternoon TORCH manily)

Looking at heading back to TORCH in the very near future, Cars on order just need a little guidence as to what oils to purchase before the cars get built.

Cheers

7000 Front 3000 Rear:thumbsup:

Try 10,000 all round ;0)

[DragonRider]

Thanks for the info Chris & Alec very much appreciated.

Just as an extra ask, what about shock oils for front and rear. I have core RC cst oils and Losi wt oils, which is better and what should I start with.

My car will be running a 6.5 and my sons will be a 8.5.

Thanks in advance.

Mark & Wesley

[AmiSMB]

I am running 7k front 3k rear in the diffs and am going 30 losi front and 25 losi rear for the shocks. Will let you know after tomorrow how it goes.

[hotrodchris]

I've got standard pistons in the shocks and running 40Front and 35rear, ran nicely at Torch last weekend:thumbsup:

[Chalkie]

Looks like the center diff will be with us soon

TM4 Center Gear Diff
http://forum.teamcracing.net/forum.php?mod=viewthread&tid=1012&fromuid=431

[Hofvander]

How much does it weigh race ready without any additional weight?

[jpmatrix]

So how are people getting on with their Tm4?
Any reliability issues as I have read that the kit crown and pinion gear in the diff have failed on occasion.

[hotrodchris]

The TM4 was running with no extra weight at the Kiddy Nat this weekend at around the 1580 mark i believe so no issues with being under weight.

[hotrodchris]

The car had issues with some crown gears occasionally going but apart from that is very robust and crash friendly!:thumbsup:
(Have probably justed tempted fate now?)
It is also an awesome drive straight from the box would thouroughly recommend it!:thumbsup:

[Chalkie]

The TM4 was running with no extra weight at the Kiddy Nat this weekend at around the 1580 mark i believe so no issues with being under weight.

It's actually about 1700 out the box and depending on the electrics/tyres, it looks light but there's a fair bit of weight in the chassis.

[AmiSMB]

I am really enjoying my TM4. I would say you do need to have the new machined ring and pinion and new cvd for the front gearbox. Apart from that I have not broken anything else on the car. For diff oils I am now running 7k in front and rear instead of 7k front and 3k rear but I know people are liking 10k all round.

[jpmatrix]

Thanks for the response.

Weird that the front diff goes and not the rear where most of strain is.

Why do you need to get another centre driveshaft together with the machined gears?

[hotrodchris]

The new gear has an out shaft through the gear box and collar the drive shaft attaches to, where as the old gear fitted over the driveshaft end and was secured with a hex screw?

I went from 5000 front and 2000 rear to 7000 and 5000 this weekend at Kiddy, changed the handling quite a lot, small changes to set up really do show up with this car.

[ron63]

Great to hear the TM4 performs well!
I'd just like to know if the XB4 wheels do really fit, offset-wise?
Because the stock white wheels are painful to look at....and i don't like the Durango ones.
Greets, Ron.

[WHITTLER555]

I ran 7k front 3k rear at Kiddy and the car felt very stable, easy to drive and a lot less tail happy than the Durango I ran last year.

No problems so far with gears.

So far I've only moved the Ackerman link forwards which seemed to smooth out the steering and made it pivot less in the corners.

More testing at RHR this weekend!

Having had an XB4 with plenty of wheels i am running them on my TM4 and had no issues with the car fitting the box at Kiddy last weekend!:thumbsup:

[ron63]

Many thanks, Chris!
So i'll give them a try.

[AmiSMB]

Having had an XB4 with plenty of wheels i am running them on my TM4 and had no issues with the car fitting the box at Kiddy last weekend!:thumbsup:

Were any of those wheels the new xray v2 front wheels with an extra 1mm offset? That would add an extra 2mm overall width to the front. Hopefully it would still fit in the box. I had that dilemma yesterday when purchasing some wheels but decided not to get the new wheels until I could check how far I was from the side of the box.

[bigred5765]

its not the wheels that were close to not fitting in the box but the end of the axels, the wheels were a good 5-10mm inside that

[hotrodchris]

Grant the wheels were the older version but as Bigred says had to dremel the front axels on both TM2 and TM4!

[OneKiwi]

Hi all
Im thinking about getting one of these as I have been doing a lot of crown and pinions in the BMAX4 ii when using it as a 2wd on high grip.

Has anyone been running it as a 2wd? I only ask as I have been using the BM as 2wd and it works really well arapt from the diff

Thoughts?
How are you all liking it on astro?
Anyone tried it on the loose stuff?
