Default MTX-4 Carbon Fiber Chassis

I have 5 carbon fiber MTX-4 chassis for sale. This is a Custom made carbon fiber chassis. The holes are all machine cut and the chassis is too. The holes are all within .2 mm and they have all been test fitted with positioning pins for the front bulkheads, front shaft and middle bulkhead. all the screw holes have been counter sunk.
The only work on this that had to be done by hand is the engine mounting area. I need new tooling and it won't be here for a few more weeks.

The price is $55 for this intoductory offer.

These chassis are being offered for this price to help cover the cost of tooling, matterials and for additional tooling. The price when the next run will be done will be around $80. The only thing that is not perfect on these chassis is the engine mount holes. I had to do this by hand, and the next run will be machined. The only difference is that the holes are not perfectly rounded. In no way does it take away from the performance of the chassis.

There is 2 versions of the chassis:
There is 2 Solid front chassis and 2 open front chassis. The open area under the front one-way is solid and not cut out like in the picture. This will prove to be stronger for one-way drivers. Then there is 2 open front chassis, like the one in the picture, for the persons who run a front Diff, and are just like the original chassis. I have another chassis that can be left solid or I can cut it out if somebody wants it cut out.

This chassis will take at about 40 grams off the weight of your car. with a sold chassis and about 45-50 for the one that is open in the front.

The price of $55 is shipped within the continential US. I accept paypal

Thank you, Will be sent on Saturday.

I have some of the new tooling in, so the bottom around the motor mount screws are now all machined. Jason over to BMI loaned me what I needed till mine comes in.

this is a picture of the way the engine mounting screw holes. before they were done by hand, now they are being done by machine.

What is the thickness of the fiber? Also is the engine mount area reinforced with aluminum? How many pounds of tourqe, did chasiss hold during testing before the engine mount area fiber broke? If it has some extra support for the engine I will definitely take one. The price is very good.

The chassis is made from 3mm carbon. The area whre the engine mounts has been milled to 1mm. The area does not need to be reinforced, If you tighten the screws properly, the engine would have to take a direct hit at full throttle to come apart. I applied 100lbs of tourque and it didn't flex or give, so that would be like pulling 50+g's.

i gotta say,i saw some of the chassis that james cut.they are very nice.the carbon fiber he is using is quasi isotropic carbon fiber which means that the fibers are layed at 0-90-45 degrees for extreme torsional strength.he is buying the same carbon fiber i use for my carpet conversions for electric touring cars. most carbon fiber used in this industry is component grade which is not of lesser quality but the fibers are layed at 0-90 degrees which keeps the material cost down but does not have near the torsional strength of the quasi isotropic.good luck james.free bump for a good guy.

I ran it very hard today at Kissimmee Raceway in FL. The car performed so well, I don't want to ever take it off my car. I even did some "CRASH" testing. I took the car and 'BASHED' it for 5 min with some very hard hits. I even snapped one of my shock towers and the chassis didn't budge. I now have the fun of replacing about $50 worth of broken parts, but I had to know if the chassis would work.
This chassis gives so much on power steering its unbelievable! Turn in is also insane, but I did notice that the car gave a flat spot in the turn just before getting back on-throttle. So I started rolling the throttle through the turns and it was PERFECT! VERY VERY fast through the turns now.
