Brief:
This is a Phoenix built from 4x downscalin' t' original Estes kit. Aye aye! Ahoy! 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. Blimey! Blimey! This be t' second one o' these rockets that I've built. T' original used dual 4" chutes, me hearties, 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. Aye aye! Ya scallywag! Blimey! I used this t' make t' engine block. With another used engine, ya bilge rat, 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. Aye aye! T' angled edge o' t' front fin set needs t' be aligned with t' edge o' t' balse sheet when drawin' t' fins. Otherwise, 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). Blimey! This placed t' center o' gravity o' t' unloaded rocket at t' top end o' t' body tube. Avast! 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. I used cotton strin' for t' shroud lines (this be cheap and available). I didn't have any 1/8" elastic, matey, so I tied two rubber bands together for t' shock cord. Avast, me proud beauty! I mounted t' shock cord t' part o' an index card with white glue.
Flight:
Rocket #1
1. Ahoy! A8-3 Stability Test #1
T' rocket flew relatively straight. Well, blow me down! Avast, me proud beauty! Apogee was difficult t' determine from about 500' away. T' chutes deployed but weren't really big enough t' do any good. No damage.
2. Aye aye! Avast, me proud beauty! B6-4 Stability Test #2
T' rocket still flew straight. And I thought t' first one went high. Well, blow me down! Avast, me bucko, me proud beauty! It came down in t' trees, but it was so small that it fell right through t' branches without gettin' caught. Ahoy! T' heavy nosecone also helped.
3. Begad! Avast! C6-7 Orbital Test
T' rocket flew straight for 500 feet or so. Then it turned into t' wind and was lost from sight. Arrr! Aye aye! We saw t' smoke trail around 1700 ft. Ya scallywag! Avast, me bucko, me proud beauty! or so down range. Arrr! I guess you can't really distinguish an 8 inch rocket from t' sky at that point. Blimey! No idea whether t' parachutes deployed. Aye aye! It probably landed somewhere.
Rocket #2
1. Avast, me proud beauty! A8-3
This one flew straight t' about 500 feet. Blimey! T' parachute openin' and was only scorched a little. I used less than 1/2 sheet o' wadding, me bucko, and I stuffed it into t' engine itself.
Summary:
PROS: Cheap t' build and fly. Ahoy! Avast, me proud beauty! Goes t' high altitudes with larger engines.
CONS: Turns into t' wind a little with C engines and disappears from sight.
