The changes can be great , dont let kids stop you let them grow you . I sat at the kistchen table with my sons at 5 and 7 , I worked on my small RC jobs like interiors , tail groups , hindeging ect , then I would get them a plastic model to build .-I have the work all over my shop .
Its great letting them explore its not about building correct at that age but about being creative . When they get to 4 and up , you can take them to the school , get them theer own littel fun park plane an watch them have a blast , we did the nitro car deal , boats ect .
Now at 15 and 18 , they have there ice hockey , girls ect and dad is backfull bore in RC fule plane lol . One more year of coaching ice hockey and then RC side will be even more of a focus .
