Cox Cessna 049 182 assembly instructions needed

Hello, I'm glad you asked this forum for help.
Humanly speaking you will find all the help possible, I assure you.
I'm going to give you some advice.
Your son is anxious, it is totally understandable, please do not do anything before you know how to do it. When there was no internet, many things had to be improvised, and many were done wrong due to ignorance, I made many mistakes, many ehh, so please, calm down.
I would like to see a photo of the model that they have there and to be able to help you, your son and you and that you enjoy each step.
I'm waiting for photos of what they want to assemble and so we can start.

Eric and Bob:
very good contribution guys!
