This is a straight forward build that even a first time builder can do and make the plane fly well and look good for years.
First issue is to inventory your parts and check for quality and any replacement Balsa ectt..
Next i like to label all the parts, put matching parts together like wing ribs and give a very lite sanding to match everything.
Finally-Trace all your parts on paper and keep with the plans (I know you want to get started), by doing this you can make easy repairs or build another 4*60 some day.
