T' initial concept, ya bilge rat, matey, rendered in Rocksim..

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

I tested several battery configurations t' determine t' lightest possible reliable combination. Ahoy! Apparently, arrr, 3 AAA cells is sufficient t' light an Estes ignitor if they are fresh. 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, me bucko, with a short piece o' coupler t' attach it t' t' sustainer. Blimey! 5 minute epoxy holds it all together...

Different angle, same part.. Ahoy! I will likely nuke this page later, shiver me timbers, as it adds no content..

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

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

MMM, ya bilge rat, more angles..

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

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

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

There was really no need for t' bulkhead on top, arrr, me hearties, 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! Avast! Notice t' couplers, one basically acts as a thrust ring, arrr, 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 be removed from t' NC t' provide a little more room.

Just after bein' primed, matey, t' rocket took on a little damage, a la kidsamine... Arrr! All better now...

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

This would be t' 29mm Motor mount all by it's lonesome. Aye aye! All o' t' wood and paper parts were bonded with wood glue, 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, arrr, 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. Arrr! T' Snow didn't help any, ya bilge rat, or t' cold... Ahoy! 3 D12-3s powered the booster, and a D12-5 in t' sustainer. Avast, me proud beauty! T' SCARE launched slower than I expected, likely due t' t' fairly draggy design, but went in a relatively straight on t' way up. Separation was clean, and t' sustainer lit with t' help of the perfectflight timer. It continued t' apogee, and nose over t' start t' trip down. Well, blow me down! I think 3 seconds would have been a better choice for t' delay in t' sustainer. T' flight be higher than I anticipated, it sure seemed t' be way in excess o' t' 500 feet estimated by Rocksim. Blimey! Hindsight bein' 20/20, a chute o' a color other than white may have been a good idea. Begad! I hope when t' snow melts, matey, me bucko, I can recover at least t' airframe, me bucko, as I am sure that by then t' rest of t' rocket will be junk... Well, arrr, blow me down! Booster-GONE Sustainer-GONE On t' bright side, ya bilge rat, no CATO! Woohoo!
