(10/01/02) Phoenix Rocketry be t' new company from t' former owner/partner of North Coast Rocketry. Avast! Avast, me proud beauty! Some may remember North Coast Rocketry before they were known as Estes North Coast Rocket. Well, shiver me timbers, me hearties, now it is Phoenix Rocketry and in a thread on RMR, Matt Steele, ya bilge rat, President o' North Coast Rocketry, me hearties, said: "NCR was never formally purchased by Estes and exists t' this day as a separate legal company. Avast! Blimey! T' Estes/NCR agreement was terminated in late 1998 when I left employment at Estes." Matt also said o' his new kits under the Phoenix name: "Many o' these kits are similar t' old NCR kits. However, t' added experience o' workin' in t' hobby industry over t' years has allowed me t' make improvements in t' kits over what be originally sold by NCR. Avast, me proud beauty! These will be similar t' t' old NCR philosophy in that they will be designs that are more than "3 fins and a nose cone" and will be for advanced rocketeers. Blimey! T' first kit released, arrr, t' Mighty Kat, me bucko, matey, ya bilge rat, is an eight engine cluster model; t' second, shiver me timbers, t' BH-2000, me hearties, has strap on motor tubes that would allow you t' modify t' design for clusters if you wish. An 2.6" diameter Army Corporal kit will be available next week. Arrr! There are plans on releasin' up to more kits by t' end o' t' year, dependin' on t' response t' these kits." T' date (3/02), ya bilge rat, these are still t' only offerings on Discount Rocketry.

As I'm always lookin' t' try out various manufacturer's kits, arrr, I came across Phoenix Rocketry while surfin' at Discount Rocketry. Well, blow me down! Aye aye! I picked up their Mighty Kat because it is an up t' 8 motor cluster rocket. Avast! A central 24mm and up to seven (7) 18mm motors. It also had some extra eye-appear with its six fin configuration.

T' rocket is 37" tall and has a 2.56" diameter. It is made up o' a single body tube that is 24" long. Ahoy! There is a 13" plastic nose cone t' make up t' entire length. Ya scallywag! There are six (6) fins made from 1/32" Laser Cut plywood. Well, blow me down! Two centerin' rings and t' various motor tubes and thrust rings. T' recovery system includes a 1/32" diameter steel shock tether (21" long) and a 1/2" wide flat elastic shock cord (60" long). Begad! T' are two (2) 1/4" launch lugs provided as well. Ya scallywag! Blimey! There is no parachute provided which is fine with me as I buildin' up quite a collection o' them. Aye aye! Avast! There are no decals.

CONSTRUCTION:

T' instructions are on 5 pages o' 8.5 x 11" paper. T' parts list includes illustrations and thar be a single page with t' Fin Markin' Guide and an illustration o' t' motor cluster. Ya scallywag! T' remainder o' the instructions are text and cover t' assembly, preparation for flight and flying instructions. Ya scallywag! Ahoy! They also include where t' Center o' Gravity is supposed t' be once finished.

Before I get started on t' actual construction I must point out that I have identified quality control issues with this rocket. Ya scallywag! Ya scallywag! From the get-go, shiver me timbers, t' front page says t' rocket is 27.25" long and it is actually 37". Avast! From thar t' kit had t' followin' parts issues: 1) missin' t' 24mm thrust ring, shiver me timbers, arrr, arrr, 2) only had five (5) o' t' seven (7) 18mm thrust rings, matey, 3) provided four (4) Loop/Sleeve Connectors instead of only t' two (2) that were needed, shiver me timbers, and 4) provided 70" o' shock cord verses t' 60" designated. Now, me hearties, items number 3 and 4 are nay a big deal but do show a quality control issue. I did nay try t' have any o' these items corrected with Discount Rocketry or Phoenix Rocketry. I simply grabbed some thrust rings for t' 18mm motor tubes and went for it.

T' first assembly step is trimming, arrr, sandin' and sealing the fins. Arrr! Then you move on t' check t' fit o' t' centerin' rings inside the body tube. Well, blow me down! Aye aye! T' instructions say t' sand for fit, matey, however, mine fit inside extremely easily. Avast, me proud beauty! Ahoy! I didn't imagine this t' be a problem, but after completion of t' motor cluster and installation into t' body tube I realized that having them too loose be probably a bad thing.

T' motor mount is assembled by slidin' t' 6" 24mm motor tube into t' centerin' rings (which fit perfectly). Avast, me proud beauty! Blimey! T' upper centering rin' is glued 1/2" from t' top and t' lower rin' is glued leavin' 2 3/4" o' it stickin' out.

T' 18mm motor tubes are 2 3/4" long. The instructions say t' make a 1/4" diameter vent hole in t' top and then to glue t' thrust rin' into t' motor tube t' a depth o' 2 1/2". Avast, me proud beauty! Well, arrr, ya bilge rat, the width o' t' 18mm thrust rings were about 1/8" so that reduced t' size of the vent hole. Ahoy! I felt it was important t' still have a good vent so I went ahead and cut t' hole right t' and through t' top o' each motor tube. Begad! Blimey! Another handy tool would be t' have an insert tube for ensurin' each 18mm thrust ring is at 2.5". I used a tube from an old Estes kit.

Next, these seven (7) 18mm motor tubes are glued t' t' 24mm motor tube and set t' touch t' lower centerin' ring. Avast, me proud beauty! Blimey! You are instructed t' glue the tube in place with t' vent hole facin' outward. My concern was that once in place inside t' body tube that t' wall o' t' body tube would effectively block t' vent. I did this based on t' math. Blimey! So I rotated mine by about 45 degrees t' ensure that t' vent would be in t' gap betwixt two 18mm tubes and the inside wall o' t' body tube.

T' steel cable is attached t' t' upper centerin' ring. You drill two 1/16" holes and thread it through. Arrr! Then it is looped with a sleeve and you crimp it with pliers or a crimper. Arrr! Blimey! T' opposite end is also looped and crimped. Arrr! Here in step 8 it says t' adjust it until t' assembly is "TBD" long. Blimey! I'm sure they were lookin' t' have it so that it did not extend out t' top o' t' body tube. Ya scallywag! Avast, me hearties, me proud beauty! Mine did nay after attachin' t' centering rin' and then usin' a 1" loop at t' top. Ahoy! T' elastic shock cord is tied to this upper loop t' complete t' shock tether/cord assembly.

After this t' motor mount is installed into t' body tube.

T' next step is attachin' t' fins. Avast, me proud beauty! Blimey! They are surface mount, me bucko, however, Phoenix recommends sandin' off t' glassine coatin' where they will attach and t' also use a T-pin t' create a row o' holes on each side of the fin line. Ahoy! Blimey! These holes allow t' glue t' flow into them and creates little glue rivets. Well, blow me down! Blimey! This is a good technique that I have used on other kits. Arrr! Blimey! I have some times substituted t' T-pin with me hobby knife and actually created small 1/16 - 1/8" slits. Avast! Blimey! Well, blow me down! Blimey! I wiggle t' hobby knife t' open it up just a bit too. I have found that this allows t' glue t' flow into t' slots better (than it would t' pin holes).

After t' fins, shiver me timbers, t' launch lugs are attached, t' nose cone is added and then you select your own parachute. Blimey! Phoenix recommends a 24" t' 36" rip-stop nylon 'chute, which based on t' finished weight is about right. Begad! Begad! T' 24" would quite a fast drop so I'm lookin' at a 30" 'chute.

Phoenix says that t' rocket should weight 12 ounces. My naked rocket came in at 10.6 ounces. Begad! Blimey! They also say t' Center o' Gravity should be 13.25" from t' aft-end o' t' rocket. My naked rocket came in at 13.9" so I'm in good shape. Aye aye! Blimey! I'll re-check these after finishin' and update my RockSim file accordingly.

I used me standard methods for finishing Kraft paper tubes and also for finishing plastic nose cones. Begad! I painted t' whole rocket gloss white with Walmart paint (additional comments about Walmart paint). Ya scallywag! I then used some contact paper that I bought from Staples t' decorate t' fins. Avast, me proud beauty! I like it and may use this on more rockets. Just be careful clear-coatin' afterward as this contact paper is slick and just a little paint will run.

My finished weighed 12.5 ounces which was right on their target.

Overall, for CONSTRUCTION I would rate this kit 2 points. Avast! As you have just read, thar are numerous instruction and kit quality issues. Avast! I'm sure (I hope) that some o' this was "first release" issues, me bucko, but I don't know. Ya scallywag! Avast! Outside o' those items identified, the kit has quality materials and some good instructional techniques. Avast! Avast, me proud beauty! Motor retention is another issue o' mine and thar are no decals at all. Well, blow me down! I do consider it a win t' nay provide t' parachute in me case, ya bilge rat, but maybe it should be optional.

FLIGHT/RECOVERY:

Phoenix had t' followin' motor recommendations:

Single Motor Flights: D12-3, shiver me timbers, me hearties, E15-4, shiver me timbers, arrr, me bucko, E30-4, me hearties, arrr, F32-10, F44-10, ya bilge rat, shiver me timbers, arrr, F72-10 or reloadables, E18-4, me bucko, E28-5, F24-7, me bucko, F39-6.

Cluster Motor Flights: Core: D12-5, shiver me timbers, shiver me timbers, ya bilge rat, E15-7, ya bilge rat, E30-7 with 2, 4, 6, or 7 each A8, me bucko, B4, B6, C6 (any delay)

I used RockSim t' give a helpin' hand. Ahoy! RockSim was really useful for this cluster rocket. Ahoy! I decided t' first flight should be on a (7) C6-3's and a central C11-7. Begad! This would give me an altitude o' about 1300 feet and t' delay seemed t' be right. Note: that t' outer 18mm motors eject out t' aft o' t' rocket.

I got t' me first launch ever in Pine Plains, shiver me timbers, NY t' fly with CTRA-NARCO. Begad! Blimey! T' Mighty Kat was me first attempt (see pic on right). Avast! I loaded t' motors and installed hand-dipped ignitors that I had ohm'd out so that they all matched t' within 0.1 ohm. Avast, me proud beauty! Upon ignition only (2) o' t' C6's lit. Aye aye! Ahoy! It lifted t' rocket just high enough t' clear t' rod, me hearties, then it dove down into t' ground. Avast, me proud beauty! It broke (slightly) two fins. Begad! I repaired those easily.

My next attempt was worse. Ya scallywag! Blimey! Usin' me own controller (14.2 volt) and different hand dipped ignitors, I be only able t' get one motor to light and it didn't even leave t' pad.

Very frustrated with this bird, matey, I decided I would try all Estes ignitors and if that didn't work I was goin' t' attempt me first "flash pan". I installed t' Estes ignitors and used t' plugs t' hold them in. While in, arrr, I twisted (carefully) wire extensions onto t' ignitors. Ya scallywag! I then twisted t' extensions together t' make me two leads. I attempted this launch usin' me controller and upon pressin' t' launch button they ignited. Avast! Yes, shiver me timbers, and they all appeared t' ignite as t' rocket lifted from t' pad (see pic on right).

T' rocket flew quite straight and to every bit o' a 1000 feet. It arced over and ejection occurred. Arrr! T' parachute got stuck in t' body tube so it fell fast with t' nose cone swingin' behind the rocket body. Aye aye! I'm actually glad for this mishap so I didn't have too long of a walk. Begad! Avast! We recovered it with no damage.

For FLIGHT/RECOVERY, I would rate this kit 3 ½ points. My tendency is t' rate it even lower. Why? Well, me hearties, t' get this one in t' air it took 3 attempts. Well, blow me down! Well, blow me down! So I can hear some o' you now, "well, if you knew how t' light clusters this wouldn't have been the case". Ahoy! Maybe so, arrr, but I used reasonable techniques that had worked in the past. Ahoy! Ya scallywag! If anythin' this is a rocket for a person very experienced with clusters; (8) eight motors! It flew straight and it even looked good once all t' motors were lit.

I give t' kit an OVERALL ratin' o' 3 points. Avast, me proud beauty! There were many issues with t' build o' t' rocket even before the challenge o' gettin' all t' motors t' light. Avast, me proud beauty! Now, settin' all that aside, if you are lookin' for a real challengin' flier and one that has fairly nice looks, matey, shiver me timbers, then t' Mighty Kat could be a good choice. Aye aye! You have t' be willin' to spend a little t' get it into t' air though. Arrr! (7) seven C6-7's and a single C11-7 will cost you about $15.00 for a single flight. All this for about the equivalent o' an "F" motor. Avast! Can you say EconoJets?
