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