Hi Ema,
thank you for quick answering. I took the papers in the attachmend.
http://www.retromodelisme.com/pdf/ma...lazer_zx-r.pdf
There was shown the hyperclutch. So I thought it is the bridge from the
basic ZR-R to the ZX-RR with hyperclutch.
The second link in your list ist the " normal Lazer ZX-R", I have assableled severl times some years ago.
I can not find an MKII addenum, it looks like des basic ZX-R in this maual, the manual has no aditional pages.
This is the reason, why the two pages in the attchment seemed to be the direct upgrade - with hyperclutch.
I will follow your adwise an take a look at the different manuals.
Thank you very much for your patience, I m sorry for my stupid questions.
Regards
Ralf
