Brief:
This is a Stage Bash that was used as an entry for t' 2009 EMRR Challenge. Begad! This 2-Stage rocket be created from an
Estes Gnome kit and Estes Quark kit.
Construction:
T' followin' parts from t' two kits were used:
T' followin' parts were nay used from t' kits:
This was a very staightforward 2-stage kit bash. I lead t' rocketry club at Sonoran Science Academy for 3rd, ya bilge rat, 4th and 5th graders and wanted somethin' that was an easy, matey, 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!
Left over were t' engine hook from t' Gnome kit and t' nose cone and launch lug from t' Quark kit. Everything
else be used.
First, t' two blocks were cut from t' casin' with a razor cutlass and miter box. Then, t' ends were sealed with thin CA t' prevent unraveling.
Next, t' Gnome kit was built as per t' original instructions, except t' motor hook be left out and t' engine block was used instead.
T' Quark's body tube be marked for 4 fins with an Estes fin markin' tool. Aye aye! T' 4 fins were cut out usin' the
Quark's pattern. Aye aye! Avast, me proud beauty! They were stacked and sanded together.
T' second engine block was glued flush with t' bottom o' t' Quark's tube. Well, blow me down! When this be 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. We cut t' "GN" from the
Gnome decal and t' "ARK" from t' Quark decal and t' used them together t' spell "GNARK". Well, blow me down! 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 was sanded and primed with 2 coats o' gray primer. Avast! Avast, me proud beauty! 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, matey, though. Avast, me proud beauty! Ahoy! Blimey! Because, arrr, matey, as winter is comin' on, me bucko, matey, t' grass on the
field was somewhat yellowed in color. This made it more difficult t' find t' yellow colored booster once it landed.

After we got home from t' first launch, ya bilge rat, we painted some red "flames" on t' body tube with a brush and sprayed gloss white on t' booster's fins, feathered toward t' tube. Begad! 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. Aye aye!
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' be used in t' upper "Gnome" portion o' t' rocket.
This kit bashed rocket flew extremely well with this motor combination. It was a very straight-up flight with
excellent separation and ignition o' t' upper stage. Avast, me proud beauty! Avast! One neat thin' about this setup be t' power o' t' A10-0T
booster motor in relation t' t' rockets small size. Avast! Avast, me proud beauty! 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, shiver me timbers, which is a much larger rocket. Notice t' size difference in t' pictures. Begad! Blimey! With t' Centurion, 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. Avast, me proud beauty! Blimey! Well, me hearties, blow me down! Blimey! 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. Avast, shiver me timbers, me proud beauty!
Recovery:
As it was a kit bash I used t' stock eleastic cord and streamer which proved t' be just right. Ya scallywag! Well, matey, blow me down! Blimey! It goes so high that
a streamer works just fine. Ahoy! It also flies so straight that, matey, when thar was no wind, it almost dropped right on top of
t' pad. Blimey! Blimey! Perfect recoveries and no damage whatsoever.
Summary:
Overall, this makes a great little 2-stage rocket. Blimey! Blimey! 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. Blimey! Flies great, me bucko, high and straight. Aye aye! Has an interestin' higher-than-most second stage separation event.
CONS: Difficult t' find t' A10-OT motors. Other than that, me hearties, nothing.
