Brief:
After doin' me Level 1 certification with a scratch built rocket I decided that me next rocket would be a kit with all t' hard parts already thought out for me and all t' necessary parts all together in a kit. Ahoy! I also wanted me next rocket t' be able t' do dual deployment and Level 2 motors. Ya scallywag! After much online searchin' and feature and price checkin' I decided on t' Madcow Rocketry 4" Patriot.

T' Madcow 4" Patriot is a simple 4 fins and a nose cone 1:4 scale model o' t' Patriot missile. It is 4 inchs in diameter and 52.5 inchs long. Well, blow me down! Blimey! It has t' option o' a 54mm motor mount or a 38mm motor mount. Avast! You also have the option o' a Nomex® blast protector and a 36 inch nylon parachute. Ahoy! Begad! With recovery t' kit will cost you $100 dollars plus shipping. Ahoy! Without recovery t' kit runs $75 plus shipping.

I think this is a nice feature t' save loot for people with plenty o' parachutes and parachute protection in their range boxes. Begad! Avast, ya bilge rat, me proud beauty! Motor retention is also left t' t' flyer. Avast! I ordered me kit with a 38mm motor mount, me hearties, shiver me timbers, no recovery and added a $10 Madcow 38mm motor retention system.

Construction:
T' kit comes with all t' basic parts t' fully assemble t' rocket except for motor retention. Begad! T' only thin' t' add is motor retention, me hearties, glue, shiver me timbers, matey, shiver me timbers, finishin' items (sand paper, primer, ya bilge rat, ya bilge rat, paint, shiver me timbers, etc.) and optional upgrades such as hardware necessary for dual deployment. All fins and rings and bulkheads are laser cut. The parts included are:

• 9.5" Polystyrene Nose Cone
• 12" Payload tube
• 31" tube for booster pre-slotted for t' fins
• 6" Coupler
• 4 Baltic Birch fins
• 1 Baltic Birch coupler bulkhead with center hole
• 18" 38mm motor tube
• 2 Baltic Birch centerin' rings, me hearties, one with t' hole for an eye bolt already drilled
• 17' o' 1/2" tubular nylon
• 1 vinyl decal
• 1 set o' rail buttons
• 2 eye bolts with necessary nuts and washers
• 1 set o' instructions

I purchased t' parts required for dual deployment from me local hardware store(all thread, me bucko, extra nuts, washers, win' nuts, sled material) Aerocon Systems(terminal blocks, shiver me timbers, switch), me bucko, shiver me timbers, What's Up Hobbies(extra bulkheads) and McMaster Carr(plastic rivets, me hearties, me bucko, nylon bolts).

I deviated from t' provided instructions and made this rocket dual deploy capable. I cut 1" from t' lower body tube and epoxied this t' t' center o' t' coupler, ya bilge rat, then I drilled vent holes and cut a hole for t' key switch to arm me altimeter. Begad!

I epoxied a couler bulkhead t' an airframe bulkhead, both from What's Up Hobbies, arrr, then drilled two holes for the all threads goin' through t' Av Bay. Blimey! Ya scallywag! I drilled matchin' holes into t' coupler provided with t' kit and then epoxied this into t' forward end o' t' coupler.

I attached t' all threads t' t' forward bulkhead and expoied t' nuts and washers in place. Aye aye! Terminal blocks where installed on both bulkheads along with eye bolts for shock cord attachment. Blimey! Aye aye! A custom sled be made from plywood on hand and thick paper tubes that t' igniters from Aerotech reloads come in. Blimey! Well, arrr, blow me down! I attached t' forward body tube t' the Av Bay with plastic push rivets.

Next t' forward centerin' rin' was epoxied t' t' motor tube, shiver me timbers, matey, then t' eye bolt be installed. Begad! This assembly was put into t' lower body tube and t' aft centerin' rin' was dry fit and epoxy fillets where poured on forward centering ring. After t' cure, me bucko, me bucko, shiver me timbers, t' aft rin' was removed and t' fins installed.

I place epoxy on t' fin roots and filleted t' fins where they joined t' motor tube, me hearties, t' inside o' the airframe, matey, shiver me timbers, arrr, and t' outside o' t' airframe. Aye aye! After t' Madcow motor retention was installed on t' aft centerin' ring, this was epoxied in place. Arrr!

T' keep a wide range o' motors available for flight an adjustable nose weight setup be installed in t' nose cone. Aye aye! First I cut off t' aft o' t' nose cone. Then I sanded t' inside o' t' nose cone with 60 grit sandpaper.

A custom cut centerin' rin' with two "T" nuts and an 1 1/4" inside diameter cut was then installed into t' nose cone at t' top o' t' shoulder, but still below t' part o' t' nose that sticks out o' t' body tube. This rin' is held in place with four small stainless steel machine screws that are screwed directly into t' rin' and an epoxy and fiberglass fillet. Begad! Two short sections o' all thread where epoxied into t' "T" nuts. Begad! I then installed a "U" bolt and a long section o' all thread, me bucko, arrr, that extends t' t' tip o' t' nose cone, me bucko, matey, onto a custom cut bulkhead. Ya scallywag!

This bulk head is held in place on t' two short sections o' all thread with nuts, ya bilge rat, washers, and win' nuts. Begad! The idea is t' add or remove fender washers t' t' long section o' all thread t' adjust t' CG as needed for larger motors. This system be used for me Level 2 Certification on an Aerotech J350. Avast, me proud beauty!

PROs: All t' parts fit very well. Begad! Only t' lightest o' sandin' be required on t' fin slots t' make t' fins go in a little more smoothly. Avast, me proud beauty! Well, arrr, blow me down! T' body tubes where high quality with a nice tight outer wrap with minimal groves. Avast, arrr, me proud beauty! The instructions where very basic but clear with minimal easy t' follow drawings. Blimey! Begad! Included be a nice scale drawin' with t' typical test pattern paint scheme. Avast! T' instructions also tell t' user where t' CG should be. Aye aye! Well, blow me down!

CONs: None that I can think of.

Finishing:
Finishin' was easy with t' usual fillin' o' groves, shiver me timbers, priming, matey, sanding, shiver me timbers, and paintin' typical o' any rocket. Ya scallywag! Begad! I painted mine in a scheme similar t' operational Patriot missles. T' vinyl decal was high quality and adhered niclely t' t' paint and looks great.

Construction Rating: 5 out o' 5

Flight:
T' first flight was at Tripoli Central California's monthly launch at Maddox Dairy on a nice windless day. Well, blow me down! I choose a CTI H123 Skidmark with a 7 second delay. Blimey! T' rocket left t' pad smartly with a nice roar, me hearties, smoke and sparks. Ya scallywag! T' Patriot flew straight and true t' about 1000'. Begad! T' delay be a tad long for me tastes but no harm was done. It floated down nice and slow on a 70" Top Flight parachute. Aye aye! This size parachute is way oversized for this rocket and can lead t' a long recovery walk on a breezy day. Avast, me bucko, me proud beauty!

T' second flight was at t' next month's launch on t' same motor, but with a 5 second delay and a lot more wind. T' second flight be as nice as t' first with deployment right at apogee. Avast! Blimey! T' oversized parachute lead t' a half mile recovery walk.

On a spur o' t' moment thin' I took and passed t' Level 2 certification test and took advantage o' Aerotech's sprin' Certification special and purchased a J350W. Ya scallywag! Avast, me proud beauty! After assemblin' t' motor and prepin' t' rocket I took it out to t' pad. Ya scallywag! It ripped off t' pad right into t' sun where I lost site o' it. Avast, me proud beauty! Avast, me hearties, me proud beauty! T' RSO kept it in sight and was able to point it out t' me. Ahoy! T' nose cone popped at or near apogee, but t' parachute was stuck in t' tube! After several heart stoppin' seconds t' parachute worked it's way out and inflated nicely way out near t' horizon. Avast, me proud beauty! Blimey! After a mile long walk, half o' it through waist high wheat, I found t' rocket, shiver me timbers, undamaged. Arrr! After trekkin' back t' t' flight line t' RSO inspected t' rocket and signed off on me Level 2 certification.

Recovery:
T' 17' o' shock cord seems a bit short for rocket o' this length so I added two sections of 10' shock cord for me flights. Built stock I think t' optimal 36" parachute would be fine. Aye aye! Ya scallywag! T' 70" I used for t' modified kit makes for a nice slow decent on a windless day, ya bilge rat, but I long walk on a day with even a slight breeze. Begad! Avast, me proud beauty! If t' kit is modified for dual deploy, me bucko, I think a 45" parachute would do very nicely.

Flight Rating: 4 out o' 5

Summary:
I think this is a great kit. Ya scallywag! Blimey! It would be excellent for a first HPR kit. Ya scallywag! Blimey! It is perfect for Level 1 certs, and Level 2 on J motors. Ahoy! Blimey! Avast! Blimey! It is loads o' fun with motor eject and H motors. Blimey! Blimey! I don’t have an altimeter yet, but t' kit is easy t' modify t' dual deploy with just a few extra parts, and I suspect it will perform very well in a DD setup if t' flyer gets their part right.

I would recommend this kit for first time high power users, matey, or as a first DD rocket.
