Gus Hi, all appears to be going well, I always think one of the best things about this hobby is the amount of learning when researching a build. Now your Driver and Radio operators hatches, the two most commonly used are MATO and TAIGEN, I would always go for the TAIGEN simply because they are pre-assembled and after you have prepared the holes for them the locating pins are their ready waiting to fit in the holes in the hinges, the MATO hatches have a lot of self assembly and are more fragile in operation and it really is just a few cents between them, whatever, I am going to watch this build with great interest. shaun
