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. Aye aye! This review looks at t' components, me bucko, 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, me hearties, an 18" long 38mm motor tube with appropriate plywood rings, shiver me timbers, a molded plastic nose cone, heavy duty nylon shock cord, me bucko, chute, and heat shield protector. Ahoy! Avast, ya bilge rat, me proud beauty! Everythin' was packaged neatly and arrived in Australia unscathed.

T' instructions take you through a very clear sequence o' assembly and were easy t' follow. Ahoy! Blimey! Each step was carefully explained and t' more complex steps were aided with self-explanatory illustrations. 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, arrr, I decided t' make 10 degree bevels on t' fins t' theoretically improve t' aerodynamics o' t' rocket. Begad! This be performed usin' a jig, shiver me timbers, 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. Well, blow me down! Once construction was complete, ya bilge rat, this rin' be epoxied into position.

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

Madcow provided rail buttons with this model, which are a great idea. Ya scallywag! 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, each about 2" long instead. Ahoy! Blimey! 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. Blimey! 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. Begad! Begad! 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. Avast, me proud beauty! Avast, me bucko, me proud beauty! I used colored electrical tape for t' blue and yellow stripes on the body. Arrr! Blimey!

T' dry weight for t' rocket was stated on t' instructions t' be approx 60oz, however, with me liberal use of epoxy and paint and once ballast be 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, ya bilge rat, so I decided t' try this first. I used an Aerotech G80-4T for the maiden flight. Blimey! Avast, me proud beauty! Flight conditions were cool with clear skies and a gentle breeze. Aye aye! Well, me hearties, blow me down! T' Phoenix lifted off t' launch pad in a slow majestic manner which correlated well t' t' thrust t' weight ratio. Avast! T' rocket flew straight and true to an estimated altitude o' 350'. Ahoy! Ejection was just after apogee and its nose be just turnin' down.

Recovery:
As usual, arrr, t' Madcow kit be supplied with a good quality 36" rip stop nylon chute and a 12" x 12" Nomex® chute protector. Avast! T' shock cord be a heavy 6mm tubular nylon, shiver me timbers, which is appropriate for a rocket o' this size. I decided t' use a 58" chute only because I be nay expectin' t' rocket t' fly very high (hence, 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. T' materials are top quality and presented in such a way as to make construction precise and simple. Blimey! T' decals make it a great lookin' sport scale version. Avast, me proud beauty! This rocket requires a minimum o' a G80 motor and is great on H motors and is therefore appropriate for an experienced flier.
