This is a sport scale version o' t' Nike Hercules anti aircraft missile. Ya scallywag! Aye aye! 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. Ya scallywag! Apogee supplies t' plans for all t' balsa parts and t' paper transitions and shrouds. Arrr! All other supplies are t' responsibility o' t' builder.

T' construction o' t' Nike Hercules is extremely challenging. Begad! 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. Avast! Aye aye! This transition piece also holds t' sustainer in place with an internal centerin' ring. Begad! Blimey! I tried t' figure out a way t' use somethin' stronger than cardstock for this internal ring, me hearties, but durin' t' initial build I had no luck. After a crash I be able t' rebuild it by addin' a thin plywood rin' t' t' paper collar before I attached it t' t' cluster tubes. Kinda tough t' describe. Avast, me proud beauty! Basically take your time in t' construction and follow t' plans. Blimey! It works fairly well.

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

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

Flight Rating: 5 out o' 5

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

Overall Rating: 4 out o' 5
