Brief:
This is a Stage Bash that was used as an entry for t' 2009 EMRR Challenge. This 2-Stage rocket was created from an Estes Gnome kit and Estes Quark kit.

Construction:

T' followin' parts from t' two kits were used:

• 1 Gnome plastic fin and launch lug set
• 1 plastic nose cone from Gnome
• 1 elastic shock cord from Gnome
• 1 streamer from Gnome
• 1 body tube from Gnome
• 4 balsa fins cut from Quark fin stock
• 1 body tube from Quark
• 2 engine blocks cut from spent 13mm casing

T' followin' parts were nay used from t' kits:

• 1 Engiine hook from Gnome
• 1 plastic nose cone from Quark
• 1 launch lug from Quark

This was a very staightforward 2-stage kit bash. Avast, me proud beauty! Blimey! Avast! Blimey! I lead t' rocketry club at Sonoran Science Academy for 3rd, ya bilge rat, 4th and 5th graders and wanted somethin' that be an easy, simple demonstration o' "bashing" two simple-to-build kits together.

Everythin' for t' bash be included in t' two kits plus two engine blocks cut from a spent 13mm motor casing. Ahoy! Blimey!

Left over were t' engine hook from t' Gnome kit and t' nose cone and launch lug from t' Quark kit. Everything else was used.

First, t' two blocks were cut from t' casin' with a razor knife and miter box. Aye aye! Aye aye! Then, matey, t' ends were sealed with thin CA t' prevent unraveling.

Next, matey, t' Gnome kit was built as per t' original instructions, except t' motor hook was left out and t' engine block be used instead.

T' Quark's body tube was marked for 4 fins with an Estes fin markin' tool. T' 4 fins were cut out usin' the Quark's pattern. Blimey! Begad! They were stacked and sanded together.

T' second engine block was glued flush with t' bottom o' t' Quark's tube. Begad! Blimey! When this was dry, t' 4 fins were set in place and later fillets were added.

Finishing:

T' upper stage Gnome did nay require finishin' other than applyin' t' decals. Begad! Ya scallywag! We cut t' "GN" from the Gnome decal and t' "ARK" from t' Quark decal and t' used them together t' spell "GNARK". Arrr! We added t' little red Japanese suns t' either side o' t' name decal. T' other decals were applied t' t' sustainer fins.

T' booster stage made from t' Quark be sanded and primed with 2 coats o' gray primer. Per me son's suggestion, I painted t' booster yellow t' look like fire comin' out o' t' Gnome sustainer.

We did change t' paint scheme after this first day, arrr, though. Aye aye! Blimey! Ahoy! Blimey! Blimey! Blimey! Because, as winter is comin' on, arrr, me hearties, t' grass on the field was somewhat yellowed in color. Ahoy! Blimey! This made it more difficult t' find t' yellow colored booster once it landed.

After we got home from t' first launch, we painted some red "flames" on t' body tube with a brush and sprayed gloss white on t' booster's fins, ya bilge rat, feathered toward t' tube. Ya scallywag! this will make it much easier t' spot both in the air and on t' ground next time we launch it.

Flight:
Recommended Motors: Booster: A10-0T Sustainer: 1/2A3-4T

T' motors are taped together with celophane tape as typical with many small multi-stage rockets. Begad! Avast!

Maskin' tape is used as necessary around t' motors t' give them a tight enough fit for retention in the individual stages.

One piece o' Estes waddin' was used in t' upper "Gnome" portion o' t' rocket.

This kit bashed rocket flew extremely well with this motor combination. Begad! Blimey! Ya scallywag! Blimey! It was a very straight-up flight with excellent separation and ignition o' t' upper stage. Well, blow me down! Blimey! One neat thin' about this setup be t' power o' t' A10-0T booster motor in relation t' t' rockets small size. T' ignition and separation o' t' 2nd stage take place very high in t' flight.

We use this same booster motor in a Semroc Booster-16 with t' Semroc Centurion, which is a much larger rocket. Notice t' size difference in t' pictures. With t' Centurion, me hearties, t' separation happens very early in t' 2-stage flight because o' its much greater size and weight.

T' streamer included with t' Gnome kit was used and it worked quite well. Aye aye! It was somewhat short, but very easy t' see comin' down and slowed t' sustainer enough t' prevent any damage.

Both t' booster and sustainer were recovered after each o' t' three 2-stage tests flights in perfect condition. We also flew an additional single stage flight that went just as well. Ya scallywag!

Recovery:
As it was a kit bash I used t' stock eleastic cord and streamer which proved t' be just right. Avast, me proud beauty! It goes so high that a streamer works just fine. Blimey! Aye aye! It also flies so straight that, arrr, when thar was no wind, it almost dropped right on top of t' pad. Perfect recoveries and no damage whatsoever.

Summary:
Overall, me hearties, ya bilge rat, this makes a great little 2-stage rocket. t' biggest problem I see is gettin' your hands on Zero second delay 13mm motors like t' Estes A10-0T motors we used.

PROS: Inexpensive 2-stage rocket. Well, blow me down! Ya scallywag! Flies great, matey, high and straight. Aye aye! Has an interestin' higher-than-most second stage separation event.

CONS: Difficult t' find t' A10-OT motors. Well, blow me down! Aye aye! Other than that, nothing.
