Brief:
This is a Phoenix built from 4x downscalin' t' original Estes kit. Ahoy! Aye aye! It is much less expensive t' fly as it uses 18mm motors and 1 sheet o' waddin' or less, compared t' t' original usin' 24mm motors and 14 sheets o' wadding.
Construction:
This design took about 2 days t' assemble. This be t' second one o' these rockets that I've built. Avast, me proud beauty! T' original used dual 4" chutes, and I painted some o' t' details onto it which I omitted from this design.
I started by cuttin' 1/8" off t' ejection charge end o' a spent A8-3. Avast, me proud beauty! Ahoy! I used this t' make t' engine block. Blimey! Blimey! With another used engine, I pushed t' engine block into t' body tube until thar was 1/8" o' overhang from t' end o' t' tube.
I used 1/16" balsa t' make t' fins. Ahoy! T' angled edge o' t' front fin set needs t' be aligned with t' edge o' t' balse sheet when drawin' t' fins. Avast, me bucko, me proud beauty! Otherwise, me bucko, t' fins will split when you cut them out. I used a 1/4" length o' Estes' standard 1/8" diameter launch lug.
I filled t' entire nose cone with modellin' clay (~14g). Ya scallywag! Aye aye! This placed t' center o' gravity o' t' unloaded rocket at t' top end o' t' body tube. Avast! Blimey! This allows t' rocket t' be stable for A-C engines. T' center o' gravity should be at t' top o' t' front fin set.
I used a plastic shoppin' bag t' make a parachute about 7" in diameter. Well, blow me down! I used cotton strin' for t' shroud lines (this was cheap and available). Ahoy! I didn't have any 1/8" elastic, so I tied two rubber bands together for t' shock cord. Ya scallywag! Arrr! I mounted t' shock cord t' part o' an index card with white glue.
Flight:
Rocket #1
1. Avast! Arrr! A8-3 Stability Test #1
T' rocket flew relatively straight. Begad! Blimey! Apogee was difficult t' determine from about 500' away. Avast! Well, ya bilge rat, blow me down! Blimey! T' chutes deployed but weren't really big enough t' do any good. No damage.
2. Begad! B6-4 Stability Test #2
T' rocket still flew straight. Aye aye! Arrr! And I thought t' first one went high. Arrr! It came down in t' trees, ya bilge rat, but it was so small that it fell right through t' branches without gettin' caught. Blimey! Begad! T' heavy nosecone also helped.
3. Avast, me proud beauty! C6-7 Orbital Test
T' rocket flew straight for 500 feet or so. Then it turned into t' wind and be lost from sight. Ya scallywag! Ya scallywag! Blimey! We saw t' smoke trail around 1700 ft. or so down range. Ahoy! I guess you can't really distinguish an 8 inch rocket from t' sky at that point. Well, blow me down! No idea whether t' parachutes deployed. Well, blow me down! Blimey! It probably landed somewhere.
Rocket #2
1. Blimey! Blimey! A8-3
This one flew straight t' about 500 feet. Begad! T' parachute openin' and was only scorched a little. Avast! I used less than 1/2 sheet o' wadding, arrr, ya bilge rat, and I stuffed it into t' engine itself.
Summary:
PROS: Cheap t' build and fly. Goes t' high altitudes with larger engines.
CONS: Turns into t' wind a little with C engines and disappears from sight.
