Query: building the tie advance

This was the first lego I built since childhood, so it brings back a lot of nice childhood memory. When I was building this product, I noticed how well this lego is engineered. The body is built to be rigid and torsionally strong. And the side panels are also well engineered. You have to build the side panel exactly right otherwise the panel well curve and you can't fit it to the craft.However, you if have a kid, who wants to play with this product after it is built, it seems to me that it is very big and heavy for a kid to play with. Also there are some parts that are snapped on to the main body which may be loosely fitted.After it is built, it is fitted on a stand. I find that the front slot that support the stand can easily become loose and come undone as it is not very well reinforced. When you have finally finish the product and display somewhere you will find that it is a big and intimidating object you have got on your hand.
