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