Sorry for t' poor grade cell phone video quality. Estes has been thoughful enough t' include a BIG "D" engine rocket in their EZ t' build lineup that you can build even while lyin' injured in bed. This is probably t' best kit in that category. Fun and easy t' build, no water slide decals,properly mounted shock cord, and beautiful launches. Aye aye! Blimey! Everythin' done right. Unforturnately t' video doesn't show t' gracefully slow parachute descent.
