I bought the ‘big daddy’ rocket and it was an advanced rocket. It was fairly easy to me, so I decided to buy an expert level rocket. This one looked good to me, and I like the paint job. It also is 2 stages, and has a really cool glider. The rocket itself is fairly easy to assemble, but I think the glider is what makes the kit harder to build. You have to glue and angle the fins of the glider at an angle so it can fly right. The instructions give you little pieces you can lay the fins on, and let them dry at an angle. I tried that, and it isn’t easy at all. All it takes is a little movement and it will collapse, and you’ll have to start all over. Instead, I took 2 sanding blocks and the fins layed easily on them. You could also take 2 objects of the same height, and do that instead. Let them dry for 2 hours atleast, to ensure that they’re dry and won’t fall apart. Overall, this is a great kit for the price and I recommend it if you want a challenge.
