This is one large rocket and is extremely easy t' put together. I read through t' instructions and test fit all t' parts together before beginning. T' instructions are easy t' follow and seem t' be precise. Aye aye! Arrr! I be surprised at the quality o' t' plastic parts, as they all fit together well with minimal flashin' (plastic from moldin' that must be cut away). T' only modification I decided t' make is t' terminate t' supplied shock cord with a swivel, me hearties, so that I can add a longer length o' cord when launchin' . Arrr! You do need t' have a 3/16" launch rod handy t' line up t' lugs when t' time comes. Before addin' t' glue t' t' upper coupler, arrr, I placed a piece o' maskin' tape on the body and pre-marked t' precise location for t' upper lug. Begad! Aye aye! Step 5c asks you to feed t' shock cord through t' body tube, ya bilge rat, careful nay t' get any glue on it. Ya scallywag! I found that it is easier just t' roll up t' elastic cord and stuff it inside the coupler for this step. There is no paintin' required and t' decals are stick on. Avast! Begad! Take your time n t' body wrap.....but isn't this always t' case! I really like this rocket. It will certainly carry a lighted payload for SoAR's Annual January night launch!
