Looks awesome! Looks like great quality and finish! But the screw holes look huge on it. Im sure its an optical illusion with the picture tho!

Nope, holes are big... :eek:

This thin of material along with using kit screws requires the bulkheads, motor mount, etc. to be touched with a 90 deg countersink and a small amount of material to be removed.
It doesn't really hurt anything but not ideal to be honest. I might do another using the thinner head ARC screws.

The screws AMX use are just called a "Low profile" 3mm CS Screw. You can find them around but they arent typically as good of quality as the amx ones.

Chassis file

curious how are you getting the cnc data for this, flat bed scanner, calipers and cad or 3d scanner?
id love to learn how to reverse engineer like this.
Would you be willing to share the file

One way is to buy a chassis and take a good photo. Upload to a CAD software and draw out the shape by overlapping the lines on the photo. Then make sure everything is to scale and double check measurements with a caliper.

I used to use my old high quality Lexmark flatbed scanner when making smaller parts, especially in my RC heli days, with a lot of flat carbon pieces. Never did a full 1/10 frame. But I'd imagine it would fit in scanner.

I use my fingers to measure then check it on a ruler then use the dimensions from the ruler.

The manual gave the drawing away...if you know... you know.

I made my own too with 2.2mm carbon, motor mount and bulkheads all retain the same 1.5mm thickness from stock. just gotta add shims on under the arm to achieve the same roll centers from stock.

Asking the important question: are you planning on selling these or it's just a personal project? :smile:

I havent even tried this myself so its a bit early to sell them. Plus after putting the car together with the chassis there are some other things i want to improve/tweak. If all goes well maybe I will. keep you guys posted.
