This is the first of two parts you ll need to create two shotteldrives ( left and right), for the FairPlay from revell scale 1/144 with stearing and beltdrive-pullies.
Aditional you will need a 1,5 mm brass or steel shaft (Model or Hardware store) and 4 peaces of gearwheels you get them at www.lemo-solar.de. Here is the link
