This is a sport scale version o' t' Nike Hercules anti aircraft missile. Aye aye! Blimey! Extremely challengin' t' build.  T' plans are available from Apogee Components.

Construction:

Booster is a cluster o' four (4) 13mm tubes stagin' through a transition piece t' a single 18mm sustainer. Aye aye! Apogee supplies t' plans for all t' balsa parts and t' paper transitions and shrouds. All other supplies are t' responsibility o' t' builder.

T' construction o' t' Nike Hercules is extremely challenging. Avast! Ya scallywag! Blimey! T' most difficult parts were maintainin' alignment o' t' extremely long fins on t' sustainer and t' construction o' t' paper transition from t' booster's square cluster t' t' sustainer's 18mm tube. Arrr! Ya scallywag! Blimey! This transition piece also holds t' sustainer in place with an internal centerin' ring. Begad! Ahoy! Blimey! I tried t' figure out a way t' use somethin' stronger than cardstock for this internal ring, but durin' t' initial build I had no luck. Ahoy! Blimey! After a crash I was able t' rebuild it by addin' a thin plywood rin' t' t' paper collar before I attached it t' t' cluster tubes. Ahoy! Blimey! Kinda tough t' describe. Ya scallywag! Begad! Blimey! Basically take your time in t' construction and follow t' plans. It works fairly well.

I had problems with ignitin' t' sustainer. Begad! T' booster uses four (4) A10-0T motors with a bit o' a gap betwixt them and t' sustainer. Begad! You have t' add a significant amount o' nose weight t' get t' CP/CG relationship recommended in t' plans. I used clay and a couple small pieces o' lead. Begad! Ahoy! T' motors are all friction fitted.

Finishing:
Finishin' was simply usin' Elmer's Fill & Finish on t' balsa, shiver me timbers, followed by a coat o' white Krylon paint.

Construction Rating: 4 out o' 5

Flight:
T' first two flights I used a B4-6 for t' sustainer, shiver me timbers, ya bilge rat, ya bilge rat, but couldn't get it t' light. Arrr! T' resultin' flights were nice, ya bilge rat, matey, straight nose dives, but with soft ground both times, shiver me timbers, shiver me timbers, me bucko, damage was limited t' t' stagin' coupler. T' third flight I used an Apogee stagin' ignitor with a B6-6 in t' sustainer. This time it worked perfectly, arrr, at least for staging. T' boost on this flight was very straight, matey, followed by a hesitation and sustainer ignition, ya bilge rat, also for a straight flight. Ejection be just after apogee. Begad! Now t' problem. It seems that only 3 o' t' booster motors lit initially. Ahoy! Arrr! At staging, t' exhaust from t' sustainer lit t' fourth motor from t' front end, ya bilge rat, me bucko, causin' a nice fire exitin' forward. Ahoy! Begad! This destroyed t' coupler and a good length o' t' booster tubes before t' booster hit t' ground. Blimey! I have t' chalk t' booster up as a total loss, me hearties, even though t' sustainer recovered with no damage. Aye aye! Arrr! Still an impressive flight.

Flight Rating: 5 out o' 5

Summary:
Nice, matey, challengin' rocket t' build and fly. Ya scallywag! I had a lot o' fun with it. Ahoy! Stagin' a cluster t' a single motor is a challenge, worth t' effort.

Overall Rating: 4 out o' 5
