Hello Overlander,
your instruction is realy very good. In germany it's like a sickness to build the 1/87 cars.
My english pages of
www.mikromodell.de are still under construction, but I try to translate my pages from german language to english. Maybee one day there is also a instruction availible.
It's realy dont't nessesary to build a brass driveline, but it's nice to have one. So you can better fix the frontaxle and the gearbox on a robust frame.
best regards
Thorsten
