T' initial concept, me hearties, matey, rendered in Rocksim..

T' rocksim export, next t' a picture o' t' actual Rocket

I tested several battery configurations t' determine t' lightest possible reliable combination. Ya scallywag! Apparently, matey, 3 AAA cells is sufficient t' light an Estes ignitor if they are fresh. Blimey! Aye aye! I be also testin' t' perfectflight timer that will be used t' ignite t' sustainer(I hope)

T' humble beginnings o' t' booster, pretty simple, a bulkhead placed in t' bottom o' a short piece o' fibre glass tube, with a short piece o' coupler t' attach it t' t' sustainer. Avast, me proud beauty! Begad! 5 minute epoxy holds it all together...

Different angle, same part.. Arrr! Blimey! Avast, me proud beauty! Blimey! I will likely nuke this page later, as it adds no content..

Wow, ya bilge rat, a picture o' t' fin placement template! I bet this one gets deleted too! Well, shiver me timbers, since it is here, I measured t' circumference o' t' tube(OD), Divided by 3, and marked a pice o' paper in t' appropriate locations, me hearties, matey, shiver me timbers, the marks were then transfered t' t' sustainer, and t' booster, ya bilge rat, t' located t' fins and t' booster motor tubes..

T' almost finished booster...T' motors(24mm) will be retained with maskin' tape, shiver me timbers, and use a maskin' tape thrust rin' as well. Avast! T' booster has 3 24mm motor tubes, and should provide enough power t' get it off the pad safely. Blimey! Ahoy! T' nose cones will be attached with 12" nylon cord scavenged from ear plugs.

MMM, more angles..

All put together..You can see t' sustainer motor assembley next t' it, wow huh!

This be t' 24mm sustainer motor mount. As it is aft eject, it is removable. Ahoy! You may notice t' clips on the bottom, shiver me timbers, hopefully they will carry t' current which will light t' sustainer motor. Arrr! At apogee, t' engine assembly will be ejected, me bucko, me bucko, pull t' chute out t' bottom, matey, and carry it safely back t' earth...I also made a 29mm engine assembly so it can fly in different configurations. Arrr! Each o' t' engine assemblies also features an eyebolt t' attach it t' t' shock cord. Blimey! They were constructed with wood glue, arrr, as opposed t' epoxy.

This would be t' battery bay, it will fit all t' batteries I want, along with t' perfectFlight Timer, arrr, with loads o' room t' spare. Arrr! This is inserted in t' top o' t' airframe, matey, and held in with a piece o' coupler (glued inside), ya bilge rat, and secured on t' other side by t' NC, which is held on with 2 screws for flight. Arrr! You may notice, arrr, arrr, thar is an eyebolt attached, ya bilge rat, me hearties, as this is where t' shock cord is attached t' t' rocket.

There was really no need for t' bulkhead on top, matey, but who knows..I wouldn't want t' batteries t' be able to leap up into t' NC anyway...

This would be t' inside o' t' airframe. Avast, me proud beauty! Notice t' couplers, arrr, one basically acts as a thrust ring, matey, while the other keeps t' battery bay in t' airframe.

MMMM Fillets...the airframe was roughed up quite a bit prior t' applyin' t' epoxy.

T' bottom was removed from t' NC t' provide a little more room.

Just after bein' primed, shiver me timbers, t' rocket took on a little damage, arrr, a la kidsamine... Ya scallywag! Blimey! All better now...

All ready t' go, me hearties, also in t' picture is a 29mm motor mount, arrr, so t' sustainer can fly on it's own..

This would be t' 29mm Motor mount all by it's lonesome. Avast, me proud beauty! Avast! All o' t' wood and paper parts were bonded with wood glue, arrr, matey, as opposed t' epoxy.

Another VERY excitin' timer test..

I needed somethin' t' light a cluster..so I guess this came with t' project..

Flight Report
Welcome t' Canada! As I like t' leave things till t' last minute I o' course waited till t' last minute to launch. Guess which area had a snow storm? Well, me bucko, ya bilge rat, I ended up launchin' by myself, as I don't like t' take t' little ones when thar be a chance someone could get a new hat. Begad! T' Snow didn't help any, me hearties, or t' cold... Begad! 3 D12-3s powered the booster, me hearties, and a D12-5 in t' sustainer. Avast! T' SCARE launched slower than I expected, arrr, shiver me timbers, likely due t' t' fairly draggy design, matey, but went in a relatively straight on t' way up. Aye aye! Well, blow me down! Separation be clean, ya bilge rat, and t' sustainer lit with t' help of the perfectflight timer. Aye aye! It continued t' apogee, me hearties, ya bilge rat, me bucko, and nose over t' start t' trip down. Aye aye! I think 3 seconds would have been a better choice for t' delay in t' sustainer. Begad! Blimey! T' flight be higher than I anticipated, it sure seemed t' be way in excess o' t' 500 feet estimated by Rocksim. Arrr! Hindsight bein' 20/20, a chute o' a color other than white may have been a good idea. Arrr! I hope when t' snow melts, I can recover at least t' airframe, me bucko, me bucko, as I am sure that by then t' rest of t' rocket will be junk... Ahoy! Aye aye! Booster-GONE Sustainer-GONE On t' bright side, arrr, no CATO! Woohoo!
