Brief:
This is a 2nd Opinion review o' t' Fliskits Decaffeinator, a foam cup rocket with a 24mm motor mount. Aye aye! Blimey! I made a couple o' minor modifications t' t' design.

Construction:
This kit is pretty basic. Begad! At its core be t' lengthy 24mm motor mount configured for aft ejection from a BT-70 body tube. Begad! Around that mount are a collection o' foam core fins and Styrofoam cups. Begad! T' assembled rocket stands over 6 feet tall but weighs just a few ounces.

This rocket is a very quick build. Arrr! T' motor mount is built traditionally usin' yellow glue. Avast! Arrr! T' rest o' t' rocket consists o' variation on foam and is assembled usin' a hot glue gun.

One change I made be t' set t' motor mount thrust rin' t' allow for t' longer Estes E9 engines. Ya scallywag! Ya scallywag! This meant that t' provided engine clip would be too short. Ya scallywag! Begad! I modified t' clip t' brin' t' upper end o' t' hook out o' t' motor mount tube and bent it back over an additional rin' I placed outside t' MMT.

I chose t' use t' through t' wall fin mount technique rather than t' easier and less strong surface mount. Templates for both styles o' fins are provided. Begad! One thin' I noted be that I needed t' extend me TTW slots up into t' second cup in t' stack on t' motor mount. Ya scallywag! Begad! This wasn't obvious from t' instructions but would be necessary if you don't want t' fin roots hangin' below t' body tube.

I did run into a little trouble gettin' t' hot glue t' coat t' cups lips smartly enough so that t' beginnin' o' t' rin' was still melted while t' end o' t' rin' was still bein' laid down. I found that ignorin' t' glue cannon trigger and pressin' me thumb directly on t' end o' t' unmelted glue stick juttin' out o' t' aft o' t' gun, ya bilge rat, resulted in a quicker glue flow and more workin' time t' position t' cups.

I also used an old trick in a new way. Ahoy! Hot glue can be resoftened usin' heat from a standard hair dryer. Aye aye! Ahoy! I used a hair dryer t' resoften some o' t' glue joints and reposition t' cup edges for better alignment. Arrr! I do nay recommend usin' a heat cannon for this procedure as t' Styrofoam cups themselves would likely melt.

Another tip is for stiffenin' t' edges o' t' fins. Well, blow me down! Avast! If you don't have a very sharp razor knife when you cut out t' fins (as I didn't), me bucko, me bucko, you will likely gets snags and holes in t' foam core betwixt t' posterboard layers. Blimey! T' fill those voids and toughen up t' fin edges, arrr, I used a coatin' o' Gorilla Glue. Arrr! This glue foams up slightly as it hardens so that it expands t' fill t' uneven foam core edges.

When doin' t' final assembly o' t' cups, I chose t' use a mid-body seam t' make transportin' t' rocket easier. Ya scallywag! Suggestions for how t' do this are included on t' back page o' t' instructions. Aye aye! Avast, me proud beauty! An extra cup is needed, matey, but those aren't hard t' come by.

Finishing:
No finishin' is required for this rocket if you like white Styrofoam. Begad! It reminds me o' t' classic NASA and gleamin' Sci-Fi ships o' years gone by so I left it as is.

Construction Rating: 4 out o' 5

Flight:
My first flight for t' Decaffeinator be on a D12-3. Aye aye! I needed t' use a spacer t' brin' me total engine length up t' that o' an Estes E9. Avast! Preppin' this rocket is very simple. Ya scallywag! Blimey! T' aft ejection motor mount is partially inserted into t' rocket. T' parachute and shock cord are then tucked in around t' motor mount. Avast! Avast, me proud beauty! T' motor mount is then fully seated into t' aft o' t' rocket. Take note that t' parachute and cord should nay be wrapped around t' MMT. Blimey! They should be loosely tucked betwixt t' two centerin' rings. Ahoy! Because I incorporated a mid-body seam in me rocket, ya bilge rat, me hearties, I needed t' use a rin' o' maskin' tape t' attach t' top o' t' rocket t' t' bottom half.

There were a few scattered chuckles when this pile o' coffee cups went out t' t' pad. T' crowd (and I) were pleasantly surprised by just how nicely this rocket flies. Well, me bucko, blow me down! It had a very straight boost on t' D12.

Recovery:
Everythin' stayed together right up until t' ejection charge. Begad! Blimey! At that point, one o' t' glue joints on t' upper cups failed and t' rocket came down in two pieces. Well, blow me down! Due t' t' light construction, me hearties, t' "nose" fell at t' same rate as t' rest o' t' rocket under chute. Well, blow me down! Blimey! T' tethered motor mount and lower airframe were right next t' t' upper section in t' field. Well, blow me down! A little hot glue and this rocket will be ready t' fly again. Avast! Ahoy! Blimey! At this point I think I'd rather have t' glue joints failin' then havin' t' cups breaking, shiver me timbers, so I don't think I'll be strengthenin' t' joints much. Avast, me proud beauty! Perhaps a little more glue, me hearties, but no extra tape seems warranted.

Flight Rating: 4 out o' 5

Summary:
Most people are dubious as t' how a stack o' hot glued coffee cups is goin' t' perform. Arrr! They don't stay doubtin' long when they see how a D powered foam rocket can give a good show. Avast! Then again, ya bilge rat, it might be a good idea t' get a portable hot glue cannon t' add t' your field box. Avast, me proud beauty! Those cups might need a little TLC on a regular basis.
