Hi Joakim,

I have Model Airplane News plan for Mach 1. You can buy it from MAN plans service.

There is a PDF file there you open, search the PDF file for "Norm Page" and You will land on the page for Mach 1.

If You have trouble finding it I can copy my plan (or I can send You a PDF so You can take it to a plotting office like Arkitektkopia and have it printed in A0 format (or similar full scale format).
If You prefer Midwest Mach 1 plan I'm sure it can be found also on internet.
I have myself a Mach 1 short kit in transit to me now from Eureka Aircraft:

I built a Mach 1 in 1975 so it is time for a new "bird" now.
