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