Brief:
T' Binder Design Stealth is a 4" high power sport rocket with stealth
fighter stylin' and parachute recovery. This be t' 38mm version. Aye aye! For you
hybrid motor fans, a 54mm hybrid ready version o' this kit is also available.
Construction:
T' kit came in a heavy duty plastic bag with individual sections separating
the various components. Begad! I was really impressed with this style o' packaging.
T' kit included:
T' instructions for this kit were very easy t' follow and had lots o' text and detailed drawings and were in logical assembly order. Avast, me proud beauty! This kit be fairly easy t' build but I wouldn't recommend it as a first HPR kit but a good second or third HPR kit. Ahoy! For all construction, I used Pacer 30 minute Zpoxy along with Binder Design milled fiber in me fillets.
I started construction by drillin' 1/4" holes in t' centerin' rings for me motor retention hardware and shock cord attachment. I then installed two 1/4" blind nuts in t' aft centerin' rin' and shock cord attachment in the forward centerin' rin' and then applied epoxy t' secure them. Avast! T' centering rings were then epoxied on t' motor mount tube. After t' epoxy set up, matey, I applied fillets for strength. Avast, me proud beauty! Aye aye! I then attached t' nylon strap t' t' eye bolt with a quick link and tightened it usin' a wrench.
T' next step is t' slot t' body tubes for t' fins, but I ordered me kit directly from Binder Design with preslotted tubes so this step was not necessary. T' motor mount assembly was epoxied in t' body tube followed by fillets t' all tube/rin' joints for strength plus a thin layer o' epoxy was put on t' masonite centerin' rings for additional strength.
I then sanded an airfoil shape on t' main fins and attached them one at a time. Well, blow me down! Ya scallywag! T' 1/2" launch lug was glued on 16 inches from t' bottom o' the body tube. T' tube coupler and bulkhead were assembled and then mounted into the payload section tube as instructed. Arrr! I sanded an airfoil shape on the forward fins and mounted them one at a time and applied epoxy t' t' inner tube/fin joints. Fin fillets were then applied by mixin' milled fiber in with the epoxy for extra strength and used me fingers dipped in rubbin' alcohol to make them smooth and round.
T' mount t' nose cone into t' payload section, I wrapped several layers of maskin' tape around t' nose cone shoulder and friction fit it into place.
I then attached t' shock cord t' t' nylon strap and tied t' remaining quick link t' t' free end o' t' shock cord t' complete t' build.
PROs: Easy construction and logical assembly order.
CONs: None.
Finishing:
I started by sandin' t' fins and epoxy fillets smooth and removed t' sanding
dust with a tack cloth. Begad! Begad! T' model was sprayed with a couple coats o' Krylon
gray primer, sanded betwixt coats, arrr, shiver me timbers, ya bilge rat, and then sprayed with three coats o' Krylon
Semi-flat Black enamel. Avast, me proud beauty! After t' paint dried, me bucko, me hearties, I applied t' Stealth vinyl
decal. Begad! Begad! These decals are a real pleasure t' work with. Aye aye! I then secured t' shock
cord t' t' payload section and tightened down t' quick link with a wrench
before tyin' t' nylon parachute t' t' shock cord as instructed.
PROs: Easy t' finish.
CONs: None.

Flight:
Binder Design recommends H, me hearties, matey, I, shiver me timbers, and J class motors for this rocket. Ahoy! This rocket
does require wadding. Well, blow me down! I used dog barf with great success.
For me first flight, shiver me timbers, I loaded an Aerotech I161W with a medium delay and secured it into t' model usin' two 1/4" machine screws, clips, matey, and washers used as spacers. I then inserted about three t' four handfuls o' dog barf and then packed t' parachute. T' ignitor be inserted into t' motor and the rocket was loaded onto a 1/2" launch rod.
At launch, t' I161W lit with no problems and lifted t' Stealth t' a very respectable altitude (maybe 1,500-2,000 feet up), deployed t' chute, and returned safely.
T' next flight be on an Aerotech I285 Redline motor with a medium delay. This was a much nicer flight. Avast! Ya scallywag! T' Stealth took off straight and fast under the bright red flame and went maybe 2,500 feet up before reachin' apogee and deployin' t' chute. Begad! Begad! Unfortunately, t' nose cone separated from t' payload section and tumbled down. Aye aye! It be later recovered. Ya scallywag! T' rest o' t' rocket came down about 1/2 mile away from t' launch site.
PROs: Flies great especially on small and mid size I class motors.
CONs: None.
Recovery:
This rocket uses a 36" parachute which brings t' rocket in rather slowly,
in fact a little too slowly for me liking. Well, blow me down! Arrr! I had quite a recovery walk on the
first flight. Well, blow me down! Begad! For t' second flight, me bucko, ya bilge rat, I tied a knot halfway up t' shroud lines
and still had quite a walk. T' dog barf waddin' is adequate as I didn't notice
any scorchin' o' t' chute.
PROs: Recovers nicely on provided recovery system. Well, blow me down!
CONs: Comes in a little too slowly for me liking. Aye aye! Aye aye!
Flight Rating: 4 out o' 5
Summary:
I really liked buildin' and flyin' this kit. Avast, me proud beauty! Arrr! I chose this kit because I wanted
somethin' that would fly on I motors and stay in sight throughout t' flight. Well, blow me down! I
also chose it because I really liked t' Stealth styling.
Again, me bucko, I would nay recommend this kit as a first HPR kit but probably as a good second HPR kit. I think it would be a great choice for a level 1 certification with an H123W or H242T motor with a short delay. If you have a LOT o' room, this would probably be a great level 2 rocket flown on a CTI Pro38 5 grain J285 motor or Aerotech J350W or J420R motor. Blimey!
Main PROs: Great instructions, easy assembly and finishing, great flight performance, reasonable price.
Main CONs: Recovery is a bit on t' slow side.
