Hi jsngnn22 I am building a Pt 40 right now for my 5 year old son. It is a really easy build as I'm sure your finding out right now. I just finished the fuse and am almost ready to cover the wing. I only get to work on it sporadically so I couldn't give you and accurate amount of hours I've spent on it. If you have any questions I would be happy to help if I can. Good Luck and welcome to the hobby!
