Rocket PicBrief:
This is an odd-roc that is made from a lollipop/noise maker. Aye aye! Ahoy! It is a high drag design that flies well in small fields. Begad! Arrr!

Construction:
Here is what you need:

  • 1 Dunk R' Licker lollipop/noise maker
  • Estes yellow 18mm spacer tube
  • 13mm motor tube with block
  • Balsa for fins
  • 1/8in launch lug
  • Small streamer
  • Shock cord
  • Maskin' tape


Rocket PicThis is a relatively easy build. Start off by fittin' t' 18mm spacer tube inside t' Dunk R' Licker. I had t' use a little maskin' tape t' make it really snug. Begad! Then glue your shock cord on one side o' t' tube. Well, blow me down! Avast! Blimey! CA t' 18mm tube into t' Dunk R' Licker with t' shock cord mount facin' t' top o' t' rocket (this is a aft ejection model). Friction fit t' 13mm motor mount into t' 18mm tube. Aye aye! Blimey! Make sure this can slide rearward well for recovery. Ahoy! Aye aye! Blimey! After the motor mount is good, ya bilge rat, glue t' other end o' t' shock cord t' t' mount and attach t' streamer. Avast, me proud beauty!

I had t' guess on t' fins. Avast! Avast! Since it's pretty heavy on top, matey, me hearties, shiver me timbers, I used four 1/8in balsa fins o' me own design. Ya scallywag! These are glued half on t' yellow spacer tube and half on t' main rocket body. Begad! Avast, me proud beauty!

Since t' nose is like a shot glass, matey, you must make a launch lug standoff. Blimey! I used a little balsa for this. Ahoy! The launch lug is actually part o' a AeroTech igniter holder. Begad! These can be found with single use motors. Avast!


Rocket PicFinishing:
There is nothin' t' finish unless I paint t' fins someday.

Flight and Recovery:
This has only flown once, me hearties, me bucko, but I've only had it for a week. Avast! Blimey! I waited for a very calm day because I had no clue what would happen. Avast! Blimey! We loaded an A10-3T in it and hoped for t' best. Blimey! Blimey! It worked way better than I could have ever imagined and flew arrow straight t' about 200ft with ejection just past apogee. T' shock cord burned through and t' rocket nose dove into t' ground without any damage. We need t' replace it with Keelhaul®©™® and its problems should be solved. Begad! Blimey! Blimey! Blimey!

Summary:
This is a funny odd-roc that will attract lots o' attention. Avast, me proud beauty! This be made completely out o' junk around t' house. Although high drag, it performs well for small fields. Ya scallywag! If anyone does decide t' make this, I'd recommend Keelhaul®©™® thread for t' shock cord. Well, blow me down! Avast!
