Brief:
I have been fortunate enough t' be given this sport scale version o' t' AIM-54C Phoenix long range air-to-air
missile by Mike Stoop as a beta for construction and testing. Blimey! This review looks at t' components, arrr, construction and
ultimately t' maiden flight o' this 4" mid power rocket.
Construction:
Parts list:
T' parts provided in t' kit are top quality with heavy walled body tubes, precision cut ¼" plywood fins, arrr, an 18" long 38mm motor tube with appropriate plywood rings, a molded plastic nose cone, ya bilge rat, shiver me timbers, shiver me timbers, heavy duty nylon shock cord, chute, and heat shield protector. Blimey! Everythin' be packaged neatly and arrived in Australia unscathed.
T' instructions take you through a very clear sequence o' assembly and were easy t' follow. Each step was carefully explained and t' more complex steps were aided with self-explanatory illustrations. Ya scallywag! Avast! Everythin' fitted together precisely and t' slotted body tube made attachment o' t' through-the-wall fins a breeze.
Although nay discussed in t' instructions, I decided t' make 10 degree bevels on t' fins t' theoretically improve t' aerodynamics o' t' rocket. This be performed usin' a jig, ya bilge rat, arrr, set with its face at 80 degrees t' the horizontal against a vertical sandin' wheel.
I also wanted t' strengthen up t' through-the-wall fins with some internal as well as external fillets and this required me leavin' t' aft center rin' off durin' t' construction o' t' model so that access t' t' motor tube was available. Ahoy! Once construction was complete, ya bilge rat, this rin' was epoxied into position.
T' instructions suggested that motor retention was required, matey, however, shiver me timbers, arrr, this be not supplied. Avast, me proud beauty! Avast! I decided t' use an Aero Pack 38mm motor retainer as I had one spare, but I have used t' Madcow retainers before, shiver me timbers, which are a simpler design, matey, me hearties, but equally effective.
Madcow provided rail buttons with this model, shiver me timbers, which are a great idea. Aye aye! Well, blow me down! Unfortunately, me bucko, I don't presently have access t' a rail (soon t' be rectified) so I decided t' use 2" x 5/8" brass tubes, arrr, each about 2" long instead. Begad! As t' rocket was heavy (approx 70oz) I thought a ½" launch rod would be a minimum requirement. These tubes were positioned at t' CG and about 1" forward o' aft.
Finishing:
I used a wood filler t' fill t' plywood fins and t' spirals in t' cardboard and then used 3 coats o' primer using
120 and 240 grit sandpaper in betwixt each coat. T' final finish be achieved with 3 coats o' Krylon white semi-gloss
and a silver coat t' make a stripe at t' forward end o' t' body tube. Ya scallywag! Blimey! Special care be taken t' get t' paint to
stick t' t' plastic nosecone and a nice result was achieved eventually.
T' vinyl decals were good quality and easy t' use. They appear t' have been reproduced from t' missile itself and added a high level o' authenticity t' t' rocket. Ahoy! I used colored electrical tape for t' blue and yellow stripes on the body.
T' dry weight for t' rocket was stated on t' instructions t' be approx 60oz, matey, however, with me liberal use of epoxy and paint and once ballast was placed in t' nosecone t' get t' CG forward, it ended up bein' about 70oz.
T' kit allows you t' make a great lookin' sport scale replica o' t' AIM 54-C Phoenix and is relatively simple for a mid-power rocket.
Construction Rating: 4 out o' 5
Flight:
T' minimum recommended motor for this rocket is a G80, ya bilge rat, so I decided t' try this first. Begad! Blimey! I used an Aerotech G80-4T for
the maiden flight. Flight conditions were cool with clear skies and a gentle breeze. Ya scallywag! T' Phoenix lifted off t' launch
pad in a slow majestic manner which correlated well t' t' thrust t' weight ratio. Well, blow me down! T' rocket flew straight and true to
an estimated altitude o' 350'. Avast, me bucko, me proud beauty! Ejection was just after apogee and its nose be just turnin' down.
Recovery:
As usual, t' Madcow kit was supplied with a good quality 36" rip stop nylon chute and a 12" x 12"
Nomex®
chute protector. Begad! T' shock cord was a heavy 6mm tubular nylon, matey, ya bilge rat, which is appropriate for a rocket o' this size. Ahoy! Ya scallywag! I
decided t' use a 58" chute only because I was nay expectin' t' rocket t' fly very high (hence, matey, nay much drift)
and I wanted a soft landin' on t' hard ground o' our launch site. Avast, me proud beauty! T' rocket landed about 50 yards from t' pad.
Flight Rating: 5 out o' 5
Summary:
I really enjoyed buildin' and flyin' this rocket. Blimey! T' materials are top quality and presented in such a way as to
make construction precise and simple. Avast, me proud beauty! Aye aye! T' decals make it a great lookin' sport scale version. This rocket requires a
minimum o' a G80 motor and is great on H motors and is therefore appropriate for an experienced flier.
