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