BRIEF:
I first saw t' Public Missiles Phantom in a little brochure sent t' me home. Begad! It be a new release for fall o' 1998 and I really liked t' looks o' t' kit. Well, blow me down! Arrr! It is me second PML kit, me bucko, with me first bein' t' Callisto which be me Level I certification rocket.
CONSTRUCTION: There are many things t' t' Callisto and t' Phantom have in common, includin' t' 2.1" diameter, pre-slotted, PML phenolic airframe, me hearties, plastic nose cone, arrr, ya bilge rat, piston recovery system and approximate height o' 46". However, arrr, ya bilge rat, t' Phantom carries a 38mm motor mount, ya bilge rat, arrr, a 12" payload section, me bucko, shiver me timbers, a larger parachute and a unique 6-fin design. Aye aye! T' average finished weight is 26 ounces accordin' t' t' instructions, matey, arrr, however PML's webpage says 32 ounces. My finished model weighed 29 ounces . . Well, me bucko, blow me down! . Ahoy! and then 31 ounces. Well, blow me down! PML indicated t' instructions were nay correct. T' instructions were clear with illustrations t' help ensure a successful build. Ya scallywag! Aye aye! You will need 5 minute and 15 minute epoxy and sand paper t' rough up t' parts before gluing. Well, shiver me timbers, blow me down! This be noted in t' instructions. T' Phantom uses a 9.5" motor tube t' which 4" o' t' piston strap (1" nylon rated t' 4000 lbs) is glued to. Avast, me proud beauty! Begad! T' 1/4" plywood, upper centerin' rin' be pre-slotted t' allow clearance o' t' piston strap. T' piston strap is then connected t' t' piston "D" ring, shiver me timbers, which is attached t' t' 108" long, 3/4" wide elastic shock cord, which in turn is connected t' t' payload bulkhead. All t' parts were cut precisely and fit very well. T' six fins are PML's G-10 fiberglass which are passed through t' slotted airframe and glued against t' motor tube. Just be sure t' look closely at t' fins t' ensure t' correct orientation. Well, blow me down! This is especially true on t' smaller fins (4 o' them) since t' leadin' edge is 3½ and t' trailin' edge is 2¾. T' kit uses a 30" PML's Dura-Chute parachute, which is high quality rip-stop nylon with a spill hole. Avast! There are also two brass 1/4" launch lugs. For finishin' I wanted somethin' really different. I started with Elmers' Wood Filler t' fill t' spirals, then several good coats o' Plasti-Kote primer. Ahoy! I then chose a crackle paint kit from a local craft store and went t' town. Blimey! Avast! T' kit included a gold base with a black crackle top coating. I then hit t' whole thin' with a clear coat. Avast, me proud beauty! It turned out really nice in me opinion. I contacted a color coordinator (my wife) t' determine if t' red, white and black Phantom decals looked good with me paint job. Blimey! Aye aye! It be determined that it took away from t' effect and therefore they were nay used. Well, blow me down! Avast, me proud beauty! However, shiver me timbers, t' decals are peel & stick type and thar are two Phantom, arrr, me bucko, some strips and other enhancers along with a couple o' "Cert: Level 1" and some center o' pressure symbols. Well, blow me down! Aye aye! Actually a very nice collection o' decals. I built a 38mm t' 29mm motor adaptor since I do nay currently have a 38mm motor system. Begad! Begad! I should have purchased PML's Kwik-Switch system, arrr, but I didn't. Aye aye! I build a motor retention system and mounted t' 29mm adaptor t' t' 38mm motor mount. Overall, matey, arrr, for CONSTRUCTION I would rate this kit 4.5 points. Straight forward and relatively easy t' assemble. Aye aye! Blimey! Avast! Blimey! With t' 38mm mount thar be very little room on t' centerin' rin' t' put motor retention hardware. FLIGHT/RECOVERY: At NOVAAR's first sport launch o' 1999, arrr, me bucko, I readied me Aerotech RMS - 29/40-120 Reloadable Motor System. Well, blow me down! Blimey! I prepped an F52-5 and was enjoyin' all t' nice comments about t' Phantom's looks. Well, blow me down! I friction fit t' nose cone t' ensure nay losin' it (the instructions have you drill an 1/8" vent hole t' equalize pressure in t' payload section). Aye aye! I popped t' payload section off, arrr, checked and refolded t' parachute, shiver me timbers, put in a piece o' waddin' into t' motor mount then loaded t' motor. T' launch be stable and straight. Ya scallywag! Very smooth as it reached apogee, leaned over and started back toward t' ground. Avast! Avast! It never ejected and upon impact looked as though it exploded as t' phenolic shattered into pieces. Avast, me proud beauty! Begad! What happened? T' motor's ejection charge went off and it looked as if t' piston never moved (hard t' say after an impact but t' piston was still in t' unshattered portion o' t' rocket). Here is what I think: I'm nay goin' t' bad-mouth PML's piston system as I have seen others do because I have 6 flights on me Callisto and never a problem. Begad! Well, blow me down! Blimey! I think I made two mistakes. First, me bucko, I built t' rocket in t' winter time and checked t' piston movement then and it was good with no sanding. Ahoy! It was warmer on launch day AND second, matey, I never pulled t' piston out upon preparation. Blimey! Well, blow me down! Blimey! I only refolded t' parachute. Amazingly t' nose cone, arrr, once retrieved from bein' completely embedded into t' ground, me hearties, me bucko, was nay damaged in any way. Blimey! Blimey! T' entire fin section is also in good shape which I attribute t' t' use o' phenolic (brittle) tubing. Avast! Blimey! I personally think from havin' this experience with paper that t' shock o' t' impact would have damaged t' fin section worse if it wasn't phenolic. Aye aye! Blimey! I think that as t' phenolic shatters t' energy is better absorbed. Therefore, me bucko, she is goin' t' fly again, with t' piston system. REPAIRS: Repairin' t' Phantom was so easy. I simply cut off t' ragged edge o' tubin' above t' fins, me hearties, ya bilge rat, measured a cut a new body tube and put it all together. Upon t' rebuild I didn't make a new payload section, shiver me timbers, I simply made t' rocket t' same length without it. Also since t' shock cord was still attached t' t' motor mount, I had t' split a coupler lengthwise t' use betwixt t' old fin section and new body tube. FLIGHT/RECOVERY (again): This time t' Phantom was loaded up with a F52-5T. Begad! Launch was perfectly straight without t' slightest oscillation. Begad! Reached apogee, arrr, then about 1 second later t' nose cone separated. Where's t' 'chute? Where's t' 'chute? T' parachute never came out and t' rocket landed hard horizontally on t' ground. Ya scallywag! Some chipped paint and a small crack o' one fin fillet. Well, me hearties, ya bilge rat, me bucko, this just would nay do, so I loaded it up with a G80-7. Ahoy! Pow off t' pad with t' big flame o' a G80! Up and up, matey, arc, deployment . Well, blow me down! Arrr! . . Avast, me proud beauty! full deployment this time. Avast! Avast, me hearties, me proud beauty! T' Phantom uses a 30" 'chute and it descended fairly rapidly and hit fairly hard. No damage. Let's see that again. Ya scallywag! Blimey! Loaded another G80-7. Begad! Blimey! Pow! Blimey! Off she went. This time it was about a second after apogee and again full deployment and successful (although rapid) recovery. I think this bird could use a bit larger parachute. So after thinkin' about this, I have concluded that either t' Phantom was lettin' me know it wanted more power or I may have been nay puttin' enough ejection charge powder. Begad! I will fly here again on me RMS casing, but this time usin' t' full charge. For FLIGHT/RECOVERY, I would rate this kit 4 points. Each launch produced a very straight flight. Avast, me proud beauty! These are t' ones that really make t' modeler feel proud o' t' construction. Descent it really quite fast and that's from a guy that would rather have a faster descent than not. Blimey! T' ejection issues are nay deductin' any points here since I believe they were me fault. Overall, t' Phantom is a sharp lookin' rocket with t' 6 fins makin' it unique. Ease o' construction and super straight flights make this a very nice rocket for your Level I certification or just gettin' into HPR. Begad! Ya scallywag! I would suggest gettin' or buildin' a 29/38mm adaptor t' get yourself more motor versatility. Begad! I give t' kit an OVERALL ratin' o' 4.5 points.
Brief Single stage high-power model rocket with a 30" parachute recovery. Construction The PML Phantom was my first HP rocket. Construction was straight-forward with through-the-wall fins. The instruction sheet, although very brief, was concise and clear. The Phantom is a six-finned rocket. On my kit, one of the slots on the body tube was slightly off about 0.1" so the ...
