Followed t' directions with t' followin' exceptions and comments: T' directions are on one page with four drawings (unlike t' Estes kits). Avast! It is imperative that you read them thoroughly, a couple o' times. Fins are formed by sandwichin' one basswood fin betwixt two plywood fins. Arrr! It is not especially clear how some pieces are formed or attached so do a lot o' dry fitting. Arrr! It was nay clear t' me how recovery was t' be made. T' best I could tell be that t' top and bottom are t' separate and tumble t' t' ground on their own. Ahoy! I be nay comfortable with this so I added a little screw eye and a length o' Keelhaul®©™®, arrr, ya bilge rat, just t' keep t' two halves together. Blimey! T' fins are set at angles and t' rocket has a nice spin as it goes up. Arrr! T' motor (A engines are recommended) is held in by a little plastic lockin' rin' that works well. Arrr! The rocket is square and draws a lot o' attention on t' display stand. Begad! I am going to stain mine with a cherry wood color and then use a clear polyurethane just for looks. Ahoy! Begad! I would recommend this rocket as it flies well but also makes a great conversation piece .
