Just some notes and pics on a neat new kit I recently picked up after seeing a name and similar feature to a scratch design I called El Gordo...
Estes Screamin' Mimi EST2185 Skill Level 2
New for 2003
From packaging:
BT-60
25.5 inches long
5.3 ounces
18 inch parachute
C11-3, For Sound: D12-5, D12-7
"FITTED WITH 4 SUPER SONIC WHISTLES!"
"'sCREAMS' TO OVER 500 FT!"
Sealed in new packaging weighs 6.7 ounces
Package contains 3 bags of parts containing the parachute, die-cut balsa fin stock and remaining small parts including 4 round whistles and another small bag of parts.
Very professional packaging; every plastic bag has neat seals and small air holes.
4 page directions
Balsa sheets: 1.6 oz. , 0.9 oz fins only
Parts only (no stickers) 4.0 oz.
1/8 inch hard balsa stock good die-cutting, parts fell out after a couple corners cut.
4 - 4 inch BT-20
4 - whistles
4 - 1/4 inch BT-20 coupler
1 - 2 3/4 inch BT-50 engine mount
1 - 1 inch coupler loose fit over BT-50
1 - 18 inch parachute
1 - engine hook
1 - 24mm engine block
1 - 2 inch 3/16 inch launch lug
2 - 1/16 inch cardboard centering rings
1 - 18 inch BT-60
1 - PNC Mean machine/Der Red Max style(I think)
1 - 1/4 x 24 1/2 inch shock cord
Started prep by sanding outer surface of body tube and whistle tubes where fins would be glued. Also applied thin CA to ends of body tube and motor tube to strengthen and prevent unraveling of the tube.
Started assembly with motor mount. I deviated from instructions by cutting another motor mount tube from thicker LOC 24mm tubing and sanding the inside of the centering rings for fit on the thicker tubes. Also used odorless thin CA with accelerator.
Typical assembly steps follow including fin sanding and shaping and marking the tubes for all 8 fins and launch lug.
Glued motor mount in with liquid nails wood glue.
Next step is building the whistle tubes. As I've NEVER had luck with using plastic cement with plastic and paper tubing joints with model rocket kits, I used thin CA with similar terrible results! So, a little 5 minute epoxy fixed everything! I was a little surprised by the CA not working as I thought I read somewhere about it working well... but then theres the thing with the odorless CA maybe being the issue?? dunno...
Attaching the fins was a little difficult because there were so many close together. I also found the thin odorless CA to work poorly unless a thicker bead was used and accelerator applied immediatley afterward. This method produced strong joints that I am used to with normal teary-eye thin CA.
Built, no finishing 4.3 oz.
Not flown yet, WAY TOO cold on the East coast these days!
