Chassis / Frame

The new kit includes a coreless DC motor from Namiki, Japan, I suppose type CMS10-1346 (data sheet)! The 1:24 reduction gear seems to be the same as the one used in the SangoDachshund kit. The motor is excellent but way too fast, about 28'000 rpm = 467 /s. With reduction gear of 1:24 (19.4 /s) the speed at 12 V is (driving wheel diameter 9 mm) v = 9 mm * Pi * 19.4 /s = 550 mm/s = 0.55 m/s, vproto= 0.55 m/s * 87 = 47.8 m/s = 172 km/h.
