Brief:
This was a pre-production version o' t' kit and its construction varied somewhat from t' production model. Nonetheless, ya bilge rat, arrr, it is representative o' t' performance you should expect from t' production model. I have tried t' indicate where t' production model varies, however, these notes may nay be all-inclusive.
This rocket is a huge, me hearties, 18" diameter, Level 2 capable version o' Art's Delta saucer. Begad! It is built primarily from Gatorboard and includes both 38mm and 54mm motor adapters.
Construction:
Main saucer parts list:
54mm and 38mm Motor Adaptors parts list:
Materials and tools required: utility knife, X-Acto knife with new blade, ya bilge rat, spatula or other spreadin' tool, ya bilge rat, Elmer's Glue-All, 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, shiver me timbers, shiver me timbers, only bigger. Begad! Blimey! 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. Avast, me proud beauty! Blimey! Avast, me proud beauty! Blimey! These materials are both multi-layer laminates o' dense polystyrene foam, laminated with plastic and paper. Begad! Blimey! T' Gatorboard is laminated on both sides while t' Gatorflex is laminated on only one side, allowin' it t' be flexible. Cuttin' these components was much harder than standard foamboard, so new blades, patience, ya bilge rat, me bucko, and good work surface are musts. Ya scallywag! Blimey! Unfortunately, t' Gatorflex is no longer available, matey, so in t' production model, t' top and bottom shrouds are made from standard foamboard. Ahoy! Blimey! Well, blow me down! Blimey! T' make it flexible, me bucko, you make numerous cuts usin' a provided tool, ya bilge rat, which holds a hobby-knife blade. Begad! Blimey! Minus this cutting, me bucko, 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. Ya scallywag! Blimey! Once dry, shiver me timbers, matey, arrr, you sand t' hole t' fit t' 3" host body tube. Arrr! Arrr! Blimey! T' bottom is prepared similarly.
T' center plate really takes some effort and should be cut in short sections. Begad! As with t' smaller deltas, me bucko, ya bilge rat, t' edge is beveled. Well, blow me down! I didn't have t' recommended knife so I used a very sharp kitchen knife, which seemed t' work quite well.
In short, me bucko, you glue t' mount t' t' top, arrr, me bucko, coat t' inside o' t' top with slow settin' epoxy, ya bilge rat, attach t' center t' t' top, me bucko, and finally t' bottom t' t' center. Aye aye! In this beta version, t' main trick was t' align t' holes for t' launch rod. Avast, me proud beauty! In t' production model, ya bilge rat, a ¼" launch lug is glued t' t' inside o' t' 3" host tube, thus avoidin' havin' t' cut additional holes in any o' t' components. T' removable adapters slide past this lug. Blimey! Ya scallywag! After t' first flight, I retrofitted a 1/2" lug.
T' last step is t' glass t' top with t' provided fiberglass sheet. Ahoy! Begad! This too is pre-marked. Ya scallywag! I won't go into t' details here, ya bilge rat, but make sure you use slow settin' epoxy as thar be a lot o' surface area t' cover.
For both size motor mounts, ya bilge rat, you cut t' thin fins from t' basswood usin' t' provided pattern, glue them t' t' tube, arrr, me hearties, and install t' thrust ring. Arrr! Avast! Blimey! On t' 38mm mount, shiver me timbers, 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. Aye aye! Avast! You lightly friction fit your choice o' adapters and motor. Avast, me proud beauty! T' recommended motors include a wide variety o' I and J motors as well as t' Aerotech K185W and Ellis L330P. Arrr! In t' beta testing, me hearties, a wide variety o' motors were flown. Arrr! Ya scallywag! Note that although t' saucer will fly on H motors, me bucko, 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! T' saucer tore off t' pad with lots o' smoke and noise. It be a fantastic flight. Arrr! T' second flight was at a NOVAAR launch. This was a very interestin' flight. Avast! Well, blow me down! T' J110 had a nice long 7 second burn. Arrr! Because o' t' low average thrust and regressive thrust profile, ya bilge rat, t' saucer arched over and be still under power after apogee.
Recovery:
Big? No problem! Blimey! In both cases, aerobrakin' brought it down softly without damage. Begad! With t' longer J228, t' motor and adapter unseated from t' main tube upon impact. 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. It landed in an outcrop o' brush but that part o' t' field be damp and thar was no risk o' fire. Blimey! T' ensuin' smoke cloud be described as a "mushroom cloud on t' horizon". Cool! Still, me bucko, 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. Aye aye! T' beta version was an easy build yet be still enough work that you would feel proud o' your accomplishment. T' production model will take a bit more time. What do you expect from a Level 2 capable rocket anyway?!
Overall Rating: 4
Brief: This is a beautiful HPR saucer that wows the crowd with great boosts and long aerobrake recoveries. Construction: This kit comes essentially as three kits. There are the saucer itself and two motor mount kits: one for 54mm motors and one for 38mm motors. The saucer is a single central body tube, a launch lug that mounts inside the body tube, three foam sheets, and some ...
