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