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, 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, matey, arrr, precision cut ¼" plywood fins, an 18" long 38mm motor tube with appropriate plywood rings, a molded plastic nose cone, heavy duty nylon shock cord, ya bilge rat, matey, chute, and heat shield protector. 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. Begad! Each step was carefully explained and t' more complex steps were aided with self-explanatory illustrations. Arrr! 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, matey, shiver me timbers, I decided t' make 10 degree bevels on t' fins t' theoretically improve t' aerodynamics o' t' rocket. Ya scallywag! This be performed usin' a jig, 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. Avast, me proud beauty! Once construction be complete, me hearties, me bucko, this rin' be epoxied into position.

Madcow Rocketry Phoenix T' instructions suggested that motor retention was required, me hearties, however, this be not supplied. Avast, me proud beauty! Begad! I decided t' use an Aero Pack 38mm motor retainer as I had one spare, me bucko, but I have used t' Madcow retainers before, matey, which are a simpler design, ya bilge rat, but equally effective.

Madcow provided rail buttons with this model, which are a great idea. Well, blow me down! Avast, me proud beauty! Unfortunately, I don't presently have access t' a rail (soon t' be rectified) so I decided t' use 2" x 5/8" brass tubes, ya bilge rat, shiver me timbers, shiver me timbers, each about 2" long instead. Aye aye! 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. Aye aye! T' final finish was 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. Special care was taken t' get t' paint to stick t' t' plastic nosecone and a nice result be achieved eventually.

T' vinyl decals were good quality and easy t' use. Ahoy! They appear t' have been reproduced from t' missile itself and added a high level o' authenticity t' t' rocket. Well, blow me down! Blimey! I used colored electrical tape for t' blue and yellow stripes on the body. Well, blow me down! Avast! Blimey!

T' dry weight for t' rocket was stated on t' instructions t' be approx 60oz, me hearties, however, ya bilge rat, 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.

Flight:
T' minimum recommended motor for this rocket is a G80, so I decided t' try this first. Avast! I used an Aerotech G80-4T for the maiden flight. Ahoy! Well, blow me down! Flight conditions were cool with clear skies and a gentle breeze. Well, matey, blow me down! T' Phoenix lifted off t' launch pad in a slow majestic manner which correlated well t' t' thrust t' weight ratio. Begad! T' rocket flew straight and true to an estimated altitude o' 350'. Well, blow me down! Ejection was just after apogee and its nose was just turnin' down.

Recovery:
As usual, ya bilge rat, shiver me timbers, t' Madcow kit was supplied with a good quality 36" rip stop nylon chute and a 12" x 12" Nomex® chute protector. Ya scallywag! T' shock cord was a heavy 6mm tubular nylon, shiver me timbers, ya bilge rat, which is appropriate for a rocket o' this size. Begad! I decided t' use a 58" chute only because I be nay expectin' t' rocket t' fly very high (hence, shiver me timbers, me bucko, nay much drift) and I wanted a soft landin' on t' hard ground o' our launch site. T' rocket landed about 50 yards from t' pad.

Flight Rating: 5 out o' 5

Summary:
I really enjoyed buildin' and flyin' this rocket. Begad! T' materials are top quality and presented in such a way as to make construction precise and simple. 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.

Overall Rating: 5 out o' 5
