My 7 year old built the full engine in the instructions, took it apart, and started incorporating the parts into other designs. He made motorcycle V-twins and inline 4s.These parts were perfect. The instructions, which were discarded, were not too easy to follow.

My son loved building this little engine. He was hesitant to buy it with his birthday money because some reviews said the engine didn't function as they'd hoped. His went together and works nicely. He was very happy with his purchase.
