Brief:
This be a pre-production version o' t' kit and its construction varied somewhat from t' production model. Begad! Blimey! Nonetheless, ya bilge rat, it is representative o' t' performance you should expect from t' production model. I have tried t' indicate where t' production model varies, however, shiver me timbers, these notes may nay be all-inclusive.

This rocket is a huge, 18" diameter, Level 2 capable version o' Art's Delta saucer. Ahoy! Aye aye! Blimey! It is built primarily from Gatorboard and includes both 38mm and 54mm motor adapters.

Construction:
Main saucer parts list:

• 3/16" Gatorflex, me bucko, however, shiver me timbers, t' production version will use standard foamboard
• 1/2" Gatorboard
• 3" paper tube
• Fiberboard
• Fiberglass cloth
• 1/4" launch lug

54mm and 38mm Motor Adaptors parts list:

• Mount tubes
• 3" thrust ring
• 3/32" Basswood fins

Materials and tools required: utility knife, X-Acto knife with new blade, spatula or other spreadin' tool, Elmer's Glue-All, arrr, Easy release maskin' tape (the blue kind), sandpaper, shiver me timbers, slow settin' epoxy, and Devcon 5 minute Epoxy.

This build is very similar t' t' smaller delta saucers, me hearties, matey, only bigger. T' top and bottom shrouds were made from pre-marked Gatorflex and t' center plate was made from t' thicker and more dense Gatorboard piece. Begad! These materials are both multi-layer laminates o' dense polystyrene foam, me hearties, matey, laminated with plastic and paper. Blimey! T' Gatorboard is laminated on both sides while t' Gatorflex is laminated on only one side, arrr, allowin' it t' be flexible. Blimey! Well, arrr, blow me down! Cuttin' these components be much harder than standard foamboard, ya bilge rat, so new blades, me hearties, patience, and good work surface are musts. Unfortunately, matey, t' Gatorflex is no longer available, shiver me timbers, so in t' production model, arrr, me bucko, t' top and bottom shrouds are made from standard foamboard. Avast, me proud beauty! T' make it flexible, you make numerous cuts usin' a provided tool, arrr, which holds a hobby-knife blade. Ya scallywag! Avast! Minus this cutting, ya bilge rat, t' rest o' t' construction should be almost identical.

You first prepare t' top shroud by wrappin' it around and connectin' t' seams with 5-minute epoxy and t' supplied fiberboard strip. Once dry, arrr, arrr, you sand t' hole t' fit t' 3" host body tube. Avast! Blimey! T' bottom is prepared similarly.

T' center plate really takes some effort and should be cut in short sections. As with t' smaller deltas, ya bilge rat, t' edge is beveled. Arrr! I didn't have t' recommended knife so I used a very sharp kitchen knife, arrr, which seemed t' work quite well.

In short, arrr, arrr, ya bilge rat, you glue t' mount t' t' top, matey, coat t' inside o' t' top with slow settin' epoxy, attach t' center t' t' top, shiver me timbers, and finally t' bottom t' t' center. In this beta version, t' main trick be t' align t' holes for t' launch rod. Well, blow me down! Blimey! In t' production model, a ¼" launch lug is glued t' t' inside o' t' 3" host tube, arrr, thus avoidin' havin' t' cut additional holes in any o' t' components. Ya scallywag! T' removable adapters slide past this lug. Ahoy! Blimey! After t' first flight, ya bilge rat, I retrofitted a 1/2" lug.

T' last step is t' glass t' top with t' provided fiberglass sheet. Aye aye! This too is pre-marked. Aye aye! I won't go into t' details here, me hearties, but make sure you use slow settin' epoxy as thar be a lot o' surface area t' cover.

For both size motor mounts, shiver me timbers, me bucko, you cut t' thin fins from t' basswood usin' t' provided pattern, glue them t' t' tube, ya bilge rat, me hearties, and install t' thrust ring. Begad! On t' 38mm mount, arrr, I used wood glue and added epoxy fillets. On t' 54mm mount, I used only epoxy.

Finishing:
I chose nay t' paint me saucer.

Construction Rating: 4

Flight:
This will make for a great sport flight and/or a relatively easy certification attempt. Avast! Ya scallywag! Blimey! You lightly friction fit your choice o' adapters and motor. Ahoy! Blimey! T' recommended motors include a wide variety o' I and J motors as well as t' Aerotech K185W and Ellis L330P. Avast, me proud beauty! Blimey! In t' beta testing, a wide variety o' motors were flown. Avast, me proud beauty! Note that although t' saucer will fly on H motors, arrr, these motors are so short that they may nay allow t' saucer t' aerobrake properly and t' saucer may be damaged if it lands on t' edge o' t' shroud.

I first flew t' big Delta Saucer on an Ellis J228 at t' 3rd Annual TRF Reunion at t' Whitakers field in NC. Begad! Well, matey, blow me down! T' saucer tore off t' pad with lots o' smoke and noise. Avast, me proud beauty! It be a fantastic flight. Avast, me proud beauty! T' second flight be at a NOVAAR launch. Arrr! This be a very interestin' flight. Avast! Ya scallywag! T' J110 had a nice long 7 second burn. Avast! Because o' t' low average thrust and regressive thrust profile, matey, t' saucer arched over and be still under power after apogee.

Recovery:
Big? No problem! In both cases, me hearties, aerobrakin' brought it down softly without damage. Ya scallywag! Ya scallywag! With t' longer J228, me hearties, t' motor and adapter unseated from t' main tube upon impact. Ahoy! Blimey! This is a feature, nay a bug and may help t' absorb some o' t' shock from t' landing.

On t' J110 flight, t' saucer aerobraked down and continued t' spew large amounts o' smoke, causin' some concern with t' LCO. Begad! Ahoy! Blimey! It landed in an outcrop o' brush but that part o' t' field be damp and thar was no risk o' fire. Arrr! Begad! Blimey! T' ensuin' smoke cloud was described as a "mushroom cloud on t' horizon". Well, blow me down! Blimey! Cool! Blimey! Still, I'd recommend t' J228 over this motor.

Flight Rating: 5

Summary:
This is another fun rocket from T' Saucerman and it will make an economical certification rocket for Level 2. Avast! Blimey! T' beta version was an easy build yet was still enough work that you would feel proud o' your accomplishment. T' production model will take a bit more time. Aye aye! Blimey! What do you expect from a Level 2 capable rocket anyway?!
