after a considerable amount of time in the basement, the hybrid chassis are ready to go.
they are running very smooth, with new 8t pinions from CarGo Customs. The scaleauto crown gear is running quieter than the MB Slot.
gearing for all is 8/24, motor is mabuchi 11170 (FF050-SK) from ebay (2pcs for 4 euros).
motor has just the right amount of power. good brakes, good accelaration, nice top speed. Tested only at 10V, but if you push the voltage a little, it will be really fast!
The printed parts have a little good strength. some of my holes in the brass plate were not aligned correctly, and the M1.4 screws bent the brass plate. I used metric M1.4 screws from AliExpress, screwed directly into the printed material, worked great.
tried the BARC BITE tires on these chassis. level of grip is good, but right now i think that the CarGo tires offer a little more grip. they offer a very good level of controll, so.
now to put a layer of clear coat over those nice SCX compact Nascar bodies and they are ready to go!
