Brief:
This is an upscale 2+ x's, shiver me timbers, me hearties, ya bilge rat, o' t' "Cup o' Joe" saucer, for t' 2010 EMRR challenge. Well, blow me down! (I
realize this is scratch built)
Construction:
This was a pretty simple project except for alignment o' body tube. Avast, me proud beauty! Avast! After this first one, may have club build some. Aye aye! This time, with "oversized" holes t' allow alignment o' BT straight up and down.
Had all t' parts layin' around, except for t' Cool whip, whip I ate for t' container.
Tools: I opted t' glue foam board on lid, and in bottom, shiver me timbers, drill holes and cut on a scroll saw. Nay t' easiest but sure be fast. Ahoy! Good sharp hobby knife t' cut foam, drill, matey, arrr, (Loctite)epoxy, me hearties, arrr, adhesive spray, and marker or pencil.
This is a very sturdy rocket! You can coat BT in "modge podge" for a little more strength. Ahoy! Also, me hearties, shiver me timbers, add florist wire "landin' gear".
Finishing:
BE CAREFUL threadin' "landin' gear" thru pre-drilled holes in "bottom",
which is now t' top. Could VERY EASILY puncture Motor Mount.
Flight:
Because o' t' width and wind resistance, matey, me 1st motor will b a C6-5.
Prep is easy: "friction fit" a motor in place. Begad! Nothin' else need, "tumble recovery." 1st flight today 2/20 on a C6-5. Ahoy! Went perfect! ejection went off @ apogee or maybe w/nose slightly down. Avast! No damage w/soft landin' in snow.
Recovery:
Tumble recovery went fine on first flight. Avast, me proud beauty! Used a 4' long launch rod, recommended. 2nd flight
nay as high and landed right on a greenhouse. Avast! 3rd and 4th flights on C6-5s were nice. Begad! Simple and impressive rocket!
flies nice!!
Summary:
Cons" Little concerned with "lip" around lid causin' some drag. Avast, me proud beauty! Begad! Will try and
fill in with glue if needed. Well, blow me down! Avast! "Update" nay enough drag t' worry about.
You want t' body tube as close t' center o' cool whip container as u can get. Ahoy! Well, blow me down! Cut oversized holes and fill in with epoxy after lined up, matey, me bucko, straight up and down.
Pros: almost no cost t' build with leftover parts layin' around.
Fun t' launch! Hold top o' BT when insertin' motor.
Other:
Nothin' like a good sharp knife. Aye aye! Scroll saw was overkill.
