Rear Roll Center
 

Was curious about the rear roll center. Do I have something setup wrong or is it normal for the rear arm to extend a good 6-10mm beyond the bottom of the chassis when the spring is fully compressed?

Or is this the reason why everyone increases the height of the rear suspension mounts by 1-1.5mm.

Had on E4FS,... from the looks of it the shocks you are using are different.
I remember the only thing that stopped mines from going up that far was the Shocks ability to compress that much.

It depends on what shock bodies and what rear lower arms you are using.
With the FS arms(if you can get them) and the stock shocks, you won't be able to compress them that much.
With the new rear arms(RS and JS) and the Tamiya,Top Photon,3racing, Asso shocks you can compress them so high.
Nothing to worry about.
Gives you more shock travel and less flipping when riding the curbs:D:D

There is still hope for a centered design
 

Just saw this thread:

Kind of inspiring for a possible E4 project. (ie. shorty lipo, bottom chassis mounted steering)

Bring it back alive :lol::lol:

Dropped in a new Reedy Sonic 17.5 in my e4 today. And literally, it dropped right in. :eek: First motor I have been able to drop in without taking off the side brace. Pretty sweet. :nod:

I shelved my E4 for now.

When I have time later this year, I'll try to bring it back as a project.

Anyone thought of adapting the Exotek chassis kit for the TA06 onto the E4?

Letting go of the E4
 

I've decided to let go of my E4.

Its an E4JS but has been upgraded throughout short of the JS style chassis.

Its got:

• Red alum. bulkheads
• Alum. 1.5deg rear uprights
• Lightweight center shaft
• Front spool
• Rear ball diff
• 4deg alum ball bearing supported caster blocks
• Graphite shock towers front and rear.

It also have the Yodog parts on it as well.

Plus a whole lot of parts, almost enough to build another E4JS!
(Ball diffs, bulkheads, chassis, shock tower, belts, etc.)

I'm selling it cheap to fund another project. Seriously it will be less than what I paid for the option parts alone.

PM me if you're interested.:)

I have two complete E4 cars and many extras for sale if anyone is interested.
One DE ltd. Ed., one C4

PM me if interested.

Got my E4 the other day and had a good time messing with it so far.
quite pleased with how easily the car comes apart and goes together, no strange screw sizes or tricky assemblies to worry about. just unscrew shit and it falls apart.

had to raise my top deck up an additional 1mm over the 2mm sloe4 put in there already to fit my 5000mah gens ace. shaved the plastic belt tension bulkhead a little too to make the lipo go in and out smoother.

two things that are dumb i think though.. rear outer hinge pin.. why.. WHY. why would you have an e-clip in the front, then just decide to use a setscrew in the back? why not use a setscrew in both or eclip in both? seems like a decent idea to hold the pin, but also seem very easy to strip the thread.

also, the aluminum turnbuckles that have a non standard hex.. not good.

i had to use a set of needle nose pliars to adjust them which mangled them a little.
first thing ill do is transplant the titanium ones my FTtc5 used. which have standard turnbuckle wrench sizes.

kinda wish the chassis was a little bit wider to fit electronics. i plan to buy a 1251 shorty servo for this car, but still leaves part of the RX and ESC exposed to side impact ect. my tc5 def looked cleaner when all wired up.

wont get to run it til this weekend indoors, or if the rain stops ill go for a spin outside. nice car so far.

I have a Savox 1250MG new in box if you'd like a deal on one please PM me.

1250 might be a little small for a touring car. Though wouldnt mind another one for wgt in the future.

Not in a hurry atm. Ill prob get something when i do a summer parts order. We dont even run touring cars in winter.

There's a wrench that normally comes with the kits that fit the turnbuckles

Plenty have had no problems wiring or fitting electronics in the E4. The only requirement is a low profile steering servo and a micro rx which most all the newer TCs need for a clean installation. Even the electronics in my XRay is just as prone to side impact as any other TC like the E4.

Nice wrench but im not
Gonna BUY one when i have a whole car to
Scavenge from ha.

I think i might try putting the rx and esc on their side tonight. Might make it easier to tuck away wires ect.

Im out of money for a bit so my 1257tg will have to take the scrub like a man.

The "twelfth scale" servo will work fine. I have had one on my photon for some time now.

you can pm me your expected price. though i still might wait. i live in canada and shipping and chance of customs is rarely worth it unless im buying a bunch of stuff at once. thanks for the offer though. i have this servo in my 12r5.1 and love it. cheap and very fast/durable. i guess there is no reason it wouldn't work in a Touring car.
