Building rocket as hobby?

I am sure everyone have thier own interest and hobby. My hobbies (yes, I am a bit greedy) are to read story books or novels, watch animation & science series while my darling hubby read comic book & playing his gadgets. Our hobby is quite normal and nothing much interesting as compare to building model rocket. I am sure my brothers in law will be interested in this 'canggih' stuff. I would love to try it also, who knows, maybe I am the next brilliant engineer (*LOL* In my dream). Building model rocket and other stuff such as airplanes , helicopter & other more hi-tech stuff will definately in every guys dreams (not a cheap hobby :p ). I wonder if my hubby like stuff like this or not ... hmm... must really ask him this.
