Hi Greg. You took on yourself very interesting project!
The build looks great until now.
I am a papermodeler myself and just came back from several years brake.
It's a shame i didn't see this build earlier... I would probably help you a lot.
I've already build Famo myself and presented all the errors and issues in the process.
I've also build Panzer III from GPM, that shares same design as Stug.
Well.. if you still need some help in next steps on FAMO - you are welcome.
I have build threads in english on several forums and can PM you for reference.
I tried to pinpoint every problem and missing parts i found, so it is very detailed.
Nevertheless, i see that you're doing very well with the progress of FAMO, all this years! Keep up the good work!
Igor
