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