The Matrix Concepts carbon fiber losi 8ight chassis

[Semi Pro]

ok im going to keep this review short and sweet


afew weeks ago i picked up a matrix carbon fiber chassis, carbon fiber steering drag link set and carbon fiber front and rear shock towers for my lite weight losi 8ight project. Over all the fitment is good, the rear outer hinge brace hole needed alittle sanding to fit and the counter sinking on the replaceable front skid plate could have been deeper

the carbon chassis is 1.5mm longer than the stock chassis


here is a pic of the front countersinking that needs to be better


the rear countersinking




so is it worth the money? we will see this race season, does it save weight?

here is the stock chassis weight


and the matrix chassis


so over all it decreases the chassis weight by 99 grams

the steering ackermen Weighs in at just 20 grams, compared to the 38 gram stock one and the fit and finish is perfect.

the matrix carbon front shock tower weighs in at 12grams stock is 24grams
the matrix carbon rear shock tower weighs in at 20grams stock is 38 grams

so over all the matrix concepts parts shaved 147 grams off of my brushless 8ight

when are you going to be racing it? im really intrested in how it performance.

Also Wondering how much the over all car is going weight when you put the esc, motor, batterys and servo.

Looks cool, You should pick up a piece of carbon fiber and make a piece to replace the motor mount section.

im working on that right now as well as hinge braces and the steering brace

Just about a 1/2 lb. weight savings...not bad and it definitely has a coolness factor of 10

If I remember right I read that they accidentally counter sunk for metric screws and that's why they don't sit flush. I saw this on rctech.

all of the screws but the front skid plate sit flush, i have 4 front skid plates for it, it may be just this one, anyway its an easy fix to just counter sink them right and then CA the holes

well im going to have to say matrix has very bad customer service, i have been leaving them messages and e-mails for 3 weeks trying to get ahold of them about the front countersinking.

we will have to see how this plays out, its not that big of a deal yet since the race season doesnt start for afew more months in Mn.

well good new, i called and left another message, afew hours latter the owner of matrix call me back ( i wonder if he reads here?)

we did some investigating and figured out the two front holes were about 1mm off and that wasn't letting the screws sit down all the way on the chassis.

he was very cool on the phone and truely sounded sorry for not getting back to me sooner.We talked about the production and he said i was the first person who has had this problem and that he was sending a new chassis UPS 3day and he was going to test fit it just to make sure i didnt get another odd ball

i also got pics of the of their brushless conversion comeing out

i wonder how long before that chassis breaks? im not to fond of the idea myself, a lightwieght 8th scale? its gonna be as brittle as a 4 wheel soon

so you never raced a 1/10 scale off road before, carbon chassis really depend on the resins they are made with and most will actualy last longer than aluminum. there are tons of carbon 1/10 off road buggys.

why hate on the idea of a lightweight 1/8 scale?


good news, i got the new chassis and everything fits great on this one

[spcpicard]

I've been running their chassis since late December and haven't had any problems. To keep wear to a min. I use the De racing front bump skid and the rear one. On the rear one I add a thin line of CA glue in the front to keep it from curling and ripping off (bonds great with CF), which was a problem running it on my nitro. I also run the xtreme CF front shock tower instead of the MC one as it's a little thicker.

I NEED that

Sorry to bring up an old thread, but I was wondering how this chassis has performed in race conditions. Any update?
