Rick,
You are doing well working through the shortcomings of this Kit. I'm wrestling with the Mikr Mir version as well, fit issues with the fuselage are driving me to distraction the past few sessions and I'm still not "out of the woods"! Did you have to make adjustments or modifications to get the upper deck metal portion to fit? Mine is a really bad match.
As you have suggested I'm probably going with brass struts for the landing gear and the wings.
Cheers,
Lance
