a few Parts arrived

A few parts arrived the last days. i was pretty surprised how fast the shipping from HK was.

The pulley arrived, was hard to find a aluminum pulley with 40T.

40T aluminum pulley with guidance discs removed. Still needs to be reworked for fitting on the wheel.

Car ESC for 6s Lipos.

pretty much the whole electronic setup. Remote and lipobeeper are missing.

The board of choice. Santa Cruz Tiki Skull Bamboo.

belt drive ratios

cog	pulley	belt length in mm	distance in mm
18	40	300	75,5
15	40	295	76,1
15	36	285	76,9
16	40	300	77,6
18	40	305	78,0
15	40	300	78,7
15	36	290	79,5
16	40	305	80,2

The belt tensioner needs to work from 75,5-78,7 mm distance, so the adjustment is going from 75-80mm.

With this design, a 300mm belt can be used with 15-40 18-40 16-40 setup.
