The instructions have very small illustrations that are difficult to see the details needed for proper assembly. The numbers on the parts are very small as well. The battery box is defective and I need to get that replaced along with other items that were damaged and another part that wasn't included. I haven't tried getting the replacement items yet and hopefully that won't be a problem. We will see! Just FYI, I am an adult who has built numerous models, not a 12 year old.

I assisted my 9 yr. old granddaughter in assembling the kit. Worked on it for about 3 1/2 hours and very pleased with the result. It was missing 1 piece, which was replaced w/in 5 days. Great project for 8-12 age with some adult help.

Nice looking turbofan. We bought it for the look, not the functionality. It doesn't work and some parts did not fit together, but we are happy nonetheless.

Great teaching tool. Bought the Smithsonian automotive engine last year for grandson. This is just as good.

It was what I expected and was easy to assemble. I recommend the clear cover on the engine side be made of hard plastic.
