This is a "add on" booster for Estes's new "EXII Pro Series 2" model rockets. It holds t' new 29mm F15-0 black powder booster engine from Estes.
A some cardboard tubes, for t' outer body, motor mount tube, me bucko, a coupler, ya bilge rat, a cardboard thrust ring, three plastic fins, two strong plastic centerin' rings, and a Pro Series 2 engine retainer.
Pros: it 's fast. Well, blow me down! T' instructions state that it goes together with epoxy, so if your fast enough, me bucko, assembly will be over with in about 30 t' 45 minnutes, me hearties, ya bilge rat, dependin' on your epoxy o' choice. Just make sure you scuff up all t' matin' surfaces first, so t' epoxy has a good surface t' grip.
Cons: T' three plastic fins need t' be glued together first. Begad! Well, blow me down! Blimey! This makes them feel weak at first, shiver me timbers, but once t' CA glue holdin' t' fins together is cured, shiver me timbers, they feel rock solid.
T' pros and cons o' this are exactly t' same thing. Blimey! Avast! Everythin' is pre-colored black, so no real finishin' is needed. Avast, me proud beauty! Ahoy! There is one white "Estes" sticker that comes with t' kit and that is it.
I suspect that t' F15-0 engine is nay powerful enough t' use as a booster. Aye aye! Blimey! I flew this under me Trajector this previous Sunday (02/16/2014) and t' combination started cartwheelin' as soon as t' rocket left t' rod. Well, blow me down! T' instructions did nay say anythin' about wind speed safety, and me launch wind speed was only about 8mph.
Kind o' hard t' describe a recovery when both rocket and booster were on t' ground.
It's an interestin' concept, 29mm BP engines in a two stage rocket. Avast, me proud beauty! Avast, matey, me proud beauty! Perhaps t' F15-0 engine needs t' be a little more aggressive to achieve safe flight speed. Ahoy! My previous flight o' t' Trajector be on a Aerotech F22-6 composite in t' 29-40/120 reload casing, with a successful flight and recovery. Avast, me proud beauty! Ahoy!

If, for some reason, you want to put a 29/40-120 in there: you'll need to lengthen the MMT slightly, and also widen the forward end of the plastic MMT top-cone ( or leave it off entirely ).
