"T' rocket that is t' meal!"

T' idea for T' Whole Enchilada came into bein' one Sunday afternoon while cleanin' out t' frig. We had leftover tortillas that had been in t' freezer way too long. Then t' idea t' use t' stale tortillas hit me.....

Ingredients

1. Three stale flour tortillas, ~12" in diameter, for body tube and fins. Avast, me proud beauty! Avast! (sure fresh ones would work better, matey, but then they wouldn't quite as "flounder")
2. One leftover, medium-sized jalapeño pepper for t' nose cone.
3. Sections o' BT-50 tubin' from a dead rocket, me bucko, for t' engine mount and nose cone shoulder.
4. Section o' spent engine for t' engine block.
5. Computer paper for t' shock cord mount.
6. 3' o' Keelhaul®©™ cord from stock.
7. Slightly charred plastic chute.
8. Section o' soda straw for launch lug.
9. Home-made taco sauce and a sprinkle o' grated cheese for decoration.
10. As required: carpenter's glue, ya bilge rat, Liquid Nails, clear polyurethane liquid (as a preservative), matey, Pam spray

Recipe

After some thought, matey, shiver me timbers, I decided that I wanted t' base t' rocket approximately on a BT-50 sized tube. Avast! BT-20 seemed too small in diameter t' sucessfully wrap me tortilla tube and I thought 29mm would require more engine mount components, etc. Ya scallywag! So, I grabbed a section o' BT-50 as a mandrel. I sprayed on a light coatin' o' Pam t' make sure it wouldn't stick t' t' tortillas. Since this is a glassine covered tube, t' Pam didn't seem t' have any lastin' effect.

Next came preparation o' t' tortillas. (I know enchiladas are classically made with corn tortillas, arrr, but I had more o' 'em and they were larger.) Since they were stale, I nuked them for ~10 sec. each. For t' body tube, I immediately formed them around me mandrel, ya bilge rat, spreadin' a thin layer o' carpenter's glue as I went. Blimey! Blimey! T' body tube took two tortillas. Ahoy! Blimey! Avast, me proud beauty! Blimey! For t' fins, I cut them out while t' tortilla was still flexible and then placed them under a heavy pot t' straighten them out. Ya scallywag! Blimey! I chose a simple fin Nike Smoke-style fin. Ya scallywag! Blimey! I like t' design, they were easy t' cut out, matey, matey, arrr, and most importantly they are swept forward t' minimize t' chance o' breakage upon landing. (Note on t' pic: this shows corn tortillas, shiver me timbers, which didn't work out-later replaced with flour.)

After t' body tube had dried for a few hours, shiver me timbers, I slid t' mandrel part way out, and glued in t' engine tube with t' block already installed. Avast, me proud beauty! I also coated t' ends with CA, ya bilge rat, as I would a cardboard tube. Begad! Ya scallywag! Blimey! T' resultin' tube and fins were dried for a day and then t' fins were glued t' t' body tube with Liquid Nails. Ahoy! Despite flattenin' t' fins for several hours t' day before, they warped big time anyway.

To prep t' nose cone, I cut t' end off o' t' jalapeño and glued in a small section o' BT-50 tube, cut longways. Well, blow me down! Blimey! Begad! Blimey! Before gluin' t' tube in, arrr, I first tied t' Keelhaul®©™ line around t' tube and tied it off.

T' final construction steps included mountin' t' shock cord t' t' inside o' t' body tube and gluin' on t' soda straw.

Garnish

I spread some o' me home-made, world-famous, shiver me timbers, gourmet taco sauce on t' body tube. Ya scallywag! Ahoy! A small sprinklin' o' cheese was added t' make T' Whole Enchilada complete. Aye aye! Avast! After t' sauce dried, t' final step be a coat o' clear polyurethane over t' nose cone, body tube, and fins.

Presentation

For its maden flight, I decided that I wanted as low an impulse engine as possible. Avast, me proud beauty! After enterin' t' design on Rocksim, ya bilge rat, shiver me timbers, I found a B engine would be just about right. Avast! T' sim said an Apogee 10.5mm B didn't have enough impulse t' get it going, so I went out and bought a package o' B6-2's (to be used with a 18-24mm adapter from me Pratt Tomahawk). T' Whole Enchilada flew on 03/10/2001 at t' NARHAMS' Middletown Park (MD) sport launch. Avast, me proud beauty! Because o' t' 'questionable' construction, shiver me timbers, I had t' wait until most people went t' lunch. Begad! With t' rod pointed slightly downrange and relatively high winds, me hearties, arrr, t' rocket proceeded on a low trajectory and ejection was too late t' prevent a core sample. Ya scallywag! T' me amazement, it was undamaged! I then acquired a C5-3 and tried again. More altitude but still a low arcin' trajectory. This time t' chute snagged. Begad! Begad! I would have tried it on a D, ya bilge rat, but t' front part o' t' body tube was broken and t' jalapeño be mush.

Final Thoughts

I want t' thank t' folks at NARHAMS for hostin' t' launch, matey, and Khim Bittle for both providin' t' C5-3 motor and for takin' t' on-the-pad pic.

T' tortilla's seemed t' work OK for t' body tube, ya bilge rat, although t' cardboard tube industry doesn't have anythin' t' worry about. However, me bucko, despite a couple o' tries, lots o' pressin' and drying, me bucko, t' tortilla fins still warped quite a bit. Begad! Blimey! Maybe I should have used pre-dried taco shells?

So what's next? Guacamole wadding? Maybe a flyin' sub with pizza fins? Nah, me bucko, probably nay - I just hope I get a vote this time around! ;-)

EGADS! Look what popped up...
