Unlike 90% of the reviews, I actually built and flew mine. Pet peeve reviews not based on actually doing or tasting or whatever. Anywho... challenging build but fun. Like many of the builds, the instructions give suggestions that if followed, make it more difficult. Instructions were to glue lower fin and then upper fin assembly to rocket, then put in a tiny sliver of a wood brace and glue them together. NO!!! I test fit them to body tube and sanded them, putting sandpaper on tube and sanding so they would fit like they should onto the tube. Takes a long time. Once test fits aligned properly,  I put the brace into lower fin and glued it and waited to dry. Test fit, sanded to get angles etc and then glued lower and upper together. After solid and well dried, I then glued them to the body. I changed color scheme a little making the section the nose cone fits into silver. looks awesome. Also gluing sections together before painting is ridiculous. Esp with this size of a rocket. Flew it with d engines. Flew fantastically. Really well balanced. Fantastic rocket...prob my favorite... and I have like 15-20.
