It looks like Team Magic may be giving up on the E4 design, according to their Facebook page:

Looks a lot like a Tamiya/TOP/Sakura mix design.

or xray?

but I think itīs better than a 3 belt system.

i agree , seems like they are going in the right direction, cant wait to see the production version

Pro10noob 10-20-2011 03:24 AM

Still no gear diff tho.
But seen the room you have on the rear it would be possible to mount one.
It all depends on how many teeth the diff pulleys have;)
Shame it is black tho.
If it stays black they should call it the predetor or something.
It need a color,one that isn't been used before
Blue=Tamiya/Associated,Red=Kyosho and now Corally also, Gold/orangish=Xray,Purple=Hotbodies/HPI,Yellow=Awesomatrix,Pink=Sakura
So what color should they make the alloy?
Suggestions??:D

SebO 10-20-2011 03:29 AM

green or orange like the TM label

Evoracer 10-20-2011 04:50 AM

How sad is that. They've effectively killed any chance of a truly unique position in the market. Another humdrum 2 belt, looks like everything else design. Just WHO would buy this car vs. a Xray, Top, Tamiya, Sakura or Schumacher ? The 3 belt may have had some problems but that layout surely had potential. With TM's limited marketing effort here in the U.S. it's likely this car will have few buyers.

RC Infos 10-20-2011 07:42 AM

Hello to all

No I can talk about the new car... it wasn't possible until the TM approbation.

The prototype on Facebook is only an intermediary prototype. Some parts on this prototype aren't from TM, as all the new parts aren't definitive and ready to produce.

So, on this prototype, you can see CVDs, rear differential, steering block and rear hubs from an other company than TM.

Definitive car is planed with a rear diff gear, not ball, and with more original parts.

-------------
Why 2 belts + standard layout and no more 3 + original layout ?

Since September 2010, we tested a lot of solutions. I worked hard to find solutions for the E4RS 09... resulting on a completely new prototype for Nuremberg 2011. I ran 6 months with this prototype, and my feeling was very good. The car was more stable and more efficient... but the problem was to choose if we continue with a very original design, very similar as the E4RS09, but with my specs revision and new parts, or if we have to listen the racers and distributors around the world who are asking us for a more conventional car.

In terms of performance, I'm 99.9% sure there is no problem to obtain a very performing car on both configuration. At many races, I noticed very similar performance between my 3 belts / central layout TM car and all the others. I can't tell I was advantaged or disadvantaged by my layout. So, the problem really wasn't on the performance side.

We also studied the "user-friendly" side of the car... and off course it's very more easy and comfortable to work on a 2 belts car than on a 3 belts... which needs for sure more parts and more maintenance.

So, stay tuned... more information and pictures will come soon.

Other than the chassis and the TM stickers that car is all XRay. Literally! Not similar, they are XRay parts.

Also why the motor cut out on both sides of the chassis? Are they trying to decide which side to put the motor on? Maybe, with brushless you can program for reverse rotation like on a Tekin RS through the Hotwire but I don't see the advantage in that other than to be different.

I don't understand how two belts is any easier than working on three. I run nitro and other than the extra shaft and pulley on the front, its not that difficult.

For me the only attraction to the TM car was its balanced centralized battery layout and simplicity of design as compared to the now TA-06. If the TM car is no different than another XRay / Serpent / AE / Tamiya / 3Racing / etc....
I would move on and away to one of those above that already has better parts support.

valk 10-20-2011 10:16 AM

Looks nice but ill still go to a tc6. I was attracted to the e4 because it was different.
Ill still get one to play with =) for the slower racing im involved in i doubt the 3rd belt will hurt it a lot.

www.rcshopping.com
These guys have the most extensive stock for Team Magic. Their website is a bit clunky (slow) but they take Paypal.

or

www.rcmushroom.com
They have some parts for TM E4's just the basic and some options but thats it.

There is another store in China that has parts but you can only order from them through sending your shopping list via e-mail and then they'll reply via e-mail to confirm. You can view the products through their website but that's it. Also all their prices are in HK dollars so you'll have to convert and they don't take Paypal.

SNIPR 10-21-2011 08:33 PM

I agree whole heartedly. My whole attraction to this was the centralized configuration. The only car left is the TA06 Pro - I guess that will have to be my choice hope its the right one :confused:

Finally found a carpet setup with this car that is extremely easy to drive.

Slightly pushy entering the corner lots of mid corner and exit steering.

#3 bar in front for tighter track layouts, #4 bar in front for faster layouts.

Gear motor to be the most forward in the chassis possible.

Stays extremely consistent for the entire 6min run.

Please find pictures attached of the car. I have slowly been modifying the car from the base setup to find something that will work on my carpet track.

I needed to increase the height of the servo and use a longer servo horn to clear the square edge of the battery pack. 7mm of spacers added to steering block to eliminate bump steer.

Cheers to Capt N Slow and RC Infos, lots of useful info there.

All those mods just to obtain more flex make it look like a new car - I'd call it the E4EF (EF = Extra Flex). I wish TM would produce a new model based on that rather than a boring Xray clone.

My original E4 is due some attention, haven't had it on the track yet. The original shock caps are rubbish, will shock caps from other brands fit straight on the original E4 shocks? I may just use a set of E4JS caps if they fit.

Evoracer 11-01-2011 05:03 AM

If anyone is looking for an E4FS or knows someone looking for one (actually 2)....mine are on Ebay. I was really waiting for the new one to come out but now that TM went different direction I'll just stick with my other cars. Long live the E4 !!!!!

Thank you for your well illustrated tips and tricks. It's a shame TM is not continuing with this design as the only other fix I would have liked is a solid 1 piece under chassis (no battery hole) to prevent the occasional bowing or tweaking.

The cars rear grip tends to fade at the 3-4 min mark I was thinking it was the tire additive wearing off.

Your tips cause me to think I need to add even more rear grip to this car.

Hello

These tips pages are originaly parts of the documents I wrote for Team Magic (3 documents, septembre 2010 / december 2010 / may 2011). The original documents are for internal use only, but I think the "home-made" modifications are useful for anyone, it's why I made these special tips sheets.

I'm happy you enjoyed it.

Something you can't see on these pages, but very important, is to move the rear arms on the uprights: I always use the upper hole on the uprights, which allow me to obtain a really better rear roll center (with 0.5 to 1mm shims under FR and RR arm holders).

Wheelbase:
Have not tried cutting the rear arms down 2mm to adjust the wheel base. If anything I would want to increase the wheelbase to transfer more weight forward in this chassis. For carpet use putting more weight forward makes it much easier to drive.

Roll Center:
In front the middle location makes the car easiest to drive. By using 2mm the front end only gains .25deg of camber sometimes I use 3mm for 0deg camber gain if the traction really comes up (prevent traction roll).

Rear I used the most inside hole as it keeps the rear end planted through twisty chicanes. Have tried all sorts of shims and always seem to go back to 0mm inside and outside as best. Do you have a preferred rear setup?

Anti-Dive:
Currently use 0.5mm shim under FR as it prevents the car from falling over the front shocks under breaking and also to calm down the steering when the traction really comes up at the end of the night.

Have tried putting 0.5mm under the RR and it makes the rear end feel less planted getting into the corner. I tried this idea after seeing it on marco's setup sheet.

Hot Bodies TCX - iNLine

Old ideas become new again. Will shorty 2s lipo packs make a 3 belt design more possible?

Capt'N_Slow 11-02-2011 10:14 AM

Shorty 2s Batteries
 
http://www.teamcrc.com/crc/images/em...eries/3736.jpg
Battery Dimensions (mm): 95 x 46.5 x 25
Weight: 215 grams (7.6 oz)

Fantom 6500mAh 7.4v 2S Lipo Battery Pack, 65C
Dimensions: 138.5mm x 46.5mm x 24.5mm
Weight: 315 grams (11.11 oz)

You drop 100 grams so 1200g touring cars become a reality. As the battery is 40mm shorter it will be like running 5 cell once again but at 8.4volts.

Battery to the front for carpet and to the rear for asphalt.

YR4Dude 11-02-2011 04:43 PM

The new shorty lipos does offer some potential in new chassis designs but to speculate on the market reaction right now is just too preliminary. I think the capacity and C rating need to improve before it becomes widely accepted such that designers will start taking advantage of its size.

For now I really don't see why they can't just keep the current three belt configuration and just tweak the car to fix its shortcomings. I still think that if they borrowed some of the features from the Top Photon (ie shock towers and RCA wings), they could have a nice car going. About the battery issue, they can find a way to redesign the bulkheads such that they could use a narrower top deck with the pack sliding in from the side just slightly offcenter in conjunction with the current electronics layout and still achieve a narrow chassis design without giving up on the three belt. In doing so they can avoid the chassis flex issues by ditching the drop out battery plate.

valk 11-02-2011 05:24 PM

I thought touring cars had to weigh a certain minimum amount though?
nice to see the option of smaller batteries but i dont see the point in designing a car that relies on it. ala, crc's inline option on their 12th scale.

that tcx looks great but the team magic looks more efficiently layed out. seems like a lot of wasted space there in the steering system.
agree somewhat on the bulkhead design of the photon. less is more. but what is the advantage of vertical camber links? seems more likely to pop off.

Capt'N_Slow 11-02-2011 09:42 PM

The TCX prototype is not the sexiest step sister in the stable but it's defiantly a proof of concept.

Agreed a TC is not just a battery but with the advent of smaller components arranging the pieces of the puzzle should become easier.

valk 11-02-2011 10:23 PM

yes, but seems to me like modern lipo tcs have that sorted out pretty well. if anything, would be more of a headache to re-arange your components/add wire ect with a stubby pack.
though, shame they are dropping the e4 platform. with shorter lipos, you could mount the servo inline where the extra battery mass would have been. with modern brushless technology i wonder if the three belts are really such a hinderance.
though i wonder how well an outboard shaft drive would work.

This isn't a office Hot Bodies prototype. Its a someones private concept.

A Main Hobbies is now caring Team Magic RTR's so perhaps they are going to be bringing back the line to the USA as well.?.?

For the guys who are still running the E4RS would be wise to get this or the new Tamiya TA06?

They have everything Team Magic and KFactory. Their site is a little slow and clunky. They take Paypal and have relatively reasonable shipping costs.

Now there is a strange one.
I never had any problems with parts from them.
If they don't stock them, Mr. Lee can have them within 2 or 3 days and then send them to you.
Perhaps TM is out of parts?

RCshopping is the store from Team Magic self. I always buy my stuff their for my 1/8 scale buggy. They sometimes have no inventory for a particular part but reproducing them over and over again.

One piece bottom chassis plate with no battery cutout
 
It looks like Exotek will have their chassis kit for the TA06 some time soon. Like all other aftermarket chassis kits for the TA06, the chassis is one piece with no battery cutout.

Really the design team for the new E4 should take a close look of the Exotek chassis once its available. If they take the time to maintain the centered battery and motor three belt layout and incorporate other improvements borrowed from developments of the TA06 chassis and the TOP Racing shock tower and bulkheads, they would have a real winner to look at.

Honestly nobody is gonna bother with Team Magic if all they are going to produce is just an XRay clone.
