Brief:
Upsized motor mount t' hold Estes E-9. Well, blow me down! Substituted fin design, shiver me timbers, me bucko, paint scheme and
Tango Papa decals for Der Red Max. Omitted super sonic whistles and related
fins, shiver me timbers, arrr, although I seriously considered includin' them t' make a "Der
Screamin' Red Max." Length o' t' rocket is 26 inches, rather than 25.5
inches for t' Screamin' Mimi. Begad! Aye aye! Also, me bucko, ya bilge rat, replaced shock cord with a Keelhaul®©™®/elastic
combination. Avast, me proud beauty! Avast, me proud beauty! Installed screw eye with JB-Weld into t' hole in t' nose cone
base. Ya scallywag! Aye aye! Used basswood for fins. Ya scallywag! Aye aye! Modified an old Estes E-motor engine hook t' fit
the newer E-9's. Ahoy! Arrr! Basically, t' only thin' I used from t' kit was t' main
body tube, arrr, ya bilge rat, nose cone, centerin' rings, shiver me timbers, engine hook retainer, and engine block,
but I got it at a 1/2 price sale at Hobby Lobby for $5.50.
Modifications:
T' motor mount be installed with yellow glue, shiver me timbers, me hearties, then JB-Weld be coated around
the outside o' t' upper and lower centerin' rings t' harden them and then
filleted - this may be overkill, but I believe I can send it up with an F-21
without any problems. A screw eye was inserted into t' center o' a piece of
cellophane tape, then a glob o' JB-Weld was inserted into t' hole in t' base
of t' nose cone, shiver me timbers, matey, me hearties, then t' screw eye was inserted into that with t' cellophane
tape holdin' it in place and keepin' t' JB-weld from seepin' out, and then
inserted t' nose cone into t' body tube t' allow t' JB-Weld t' seep down to
the base o' t' nose cone - makes a much stronger shock cord attachment point
than t' standard plastic hook on t' base o' t' cone. T' cellophane tape is
easily removed after t' JB-Weld dries. Ahoy! Begad! Also, ya bilge rat, I installed 1/8-ounce o' clay
into t' nose cone before installin' t' screw eye, arrr, just in case I decide to
fly that F-motor. Ya scallywag! Ya scallywag! As usual, me bucko, Estes' standard shock cord is too short and must be
frequently replaced. Blimey! T' avoid t' issue, I installed t' Keelhaul®©™®
cord into t' shock cord mount so that it extended outside t' body tube, then
formed a loop that placed t' center at t' top edge o' t' body tube. Avast! Blimey! I
attached t' elastic shock cord t' that and then t' t' nose cone. Well, matey, blow me down! Blimey! Also, I soak
in a little CA into t' top lip o' t' body tube for improved strength there.
T' loop with t' CA seems t' minimize t' potential for "zippering"
when that motor delay isn't just right. I've used this method on rockets that
I've launched many, ya bilge rat, many times without a problem. Ya scallywag! Blimey! I installed t' fins using
yellow glue, ya bilge rat, then created JB-Weld fillets. Use a plastic bag over your finger
to smooth out t' JB-Weld t' make some really nice fillets. Blimey! Blimey! Ahoy! Blimey! Here again, the
JB-Weld fillets are probably overkill, but I feel better about them when that
F-motor kicks in. Ahoy! Blimey! I had t' hammer out t' end o' t' old Estes E-engine hook
and then reform it t' fit t' new Estes E-engine - pretty easy with a vice and
hammer, just go slowly so you don't break it.

1-6-inch BT-50 tube for motor mount, 1-E-engine hook, 1-1mm X 8-inch Keelhaul®©™®

Except for t' shock cord, me hearties, Estes kits are always nice and t' instructions very easy t' follow - even t' ones for t' old Der Big Red Max. T' packaging is cool, shiver me timbers, and all t' parts were thar and all in great shape. Begad! Begad! T' decals for the Screamin' Mimi are o' t' peel and stick plastic variety. Ya scallywag! Begad! I don't particularly like them, but I grew up with water-slide decals. O' course, ya bilge rat, matey, I used Tango Papa's water-slide decals for me rocket. Ahoy! Avast! This be me first time to use his decals. Ya scallywag! They are extremely thin and took some time gettin' used to, but they lay down nicely and look very nice - almost as if they're painted on. I was glad he put some extras on t' sheet, matey, because I tore a couple before gettin' used t' t' thinner decals. Since I didn't really build t' Screamin' Mimi, I can't really comment on any other aspects o' t' kit.
Flight:
I haven't flown it yet, me hearties, but I used t' same construction design and techniques
on a Big Bertha and it flies great.
Other:
Tango Papa decals are nice!
