Arrma Kraton 4S (ARA4408V2) to XC C8 ESC mount

This mount/adapter allows an XC C8 ESC to be fitted to an Arrma Kraton 4S V2 (ARA4408V2). You have to modify the car's plastic chassis by drilling the existing screw holes through on the base of the car with a 3mm or 3.2mm drill (M3 clearance) and then countersinking them from below. Use M3, 5mm or 6 mm pan head screws to mount the XC C8 ESC to the mount and then use two M3, 15mm or 16mm countersunk screws from underneath through the drilled out holes from below; whatever lower screws you use, the lower holes in the adapter are 10mm deep so push your screws into place and check they don't protrude inside the chassis by more than 10mm. The XC C8 ESC overhangs the adapter on the chassis side by a couple of mm to keep it as far away as possible from the center drive shaft but it's not a problem as the standard side pieces create a step out anyway (see picture). I used a Surpass 3670-2380kv brushless motor (longer than the Spektrum 3668 standard motor) that also has a JST connector that sticks out of the rear by a couple more mm but my motor + center Diff module can still be slid forward and easily removed without removing the ESC+adapter unit. This mount also does not interfere with the standard radio box cover. This may well fit other 3S and 4S Arrma cars but I haven't tested it. When printing, put the side with the 4 x 3mm holes in it down onto the printer plate (as in gray, not blue, picture) and then you should not need to add any supports. I added the honeycomb holes to reduce filament use, aid cooling, and reduce weight but none of these is a big deal I think; the XC C8 ESC runs cool on my setup. I've run the car into a wall hard and the mount did not break. I printed in Sunlu PLA on a Bambu P2S using AMS with 3 surface layers and 20% infill.
