@ M.Fischersworring
As you said I am 23 and it is really older than me
There is a very old style differantielle in it. Differantielle comperatible with any kind of 1:16 difs wdc robbe rĂ¼st whichever. I really wonder fire truck works about it before starting project. I made a reseach about it on internet and I found some good information but I am not native German simply
Thanks a lot for you help
