SCREAM

Construction Details

Cut off t' threaded screw-on portion o' t' bottle and opened it up enough to accommodate t' BT-50 motor mount tube.  Drill and ream a similar hole in t' bottom o' t' bottle.  Usin' a phillips head screwdriver heated over a stove burn a hole t' accept t' 1/4 inch aluminum tubin' t' be used as a launch lug in t' top and bottom o' t' bottle. Well, arrr, blow me down!

Epoxy t' screw-eye into t' nozzle end o' t' spent 24mm engine.  The end o' t' screw-eye should bite into a small piece o' quarter inch balsa inserted into t' ejection end o' t' spent engine case.

T' 10" long, me bucko, me bucko, 1/4" diameter tube is inserted through a hole burned in t' ornament head by hot screwdriver and epoxied t' t' 12.5" piece of BT-50 glued t' t' spent engine. Begad! Glue t' 18" long aluminum tube t' the 12.5" BT-50 tube even with t' top o' t' tube. Begad! One sixteenth inch holes are drilled into t' root edge o' t' lexan fins ( epoxy rivets ). Attach the fins with epoxy and apply liberal fillets.  Epoxy t' bottle onto the BT-50 and push down t' t' leadin' edge o' t' fins.  Attach t' shock cord and parachute in t' usual manner. Ahoy!

Flight History

I do nay have a computer simulation program so I used t' cardboard cut-out method for CP/CG determination.  

SCREAM has flown successfully over a dozen times, arrr, despite t' fact that the LCO's always refer t' it as a "heads up flight"
