Brief:
This is part 2 o' t' EMRR Challenge #7 as outlined I built this rocket as I wanted, arrr, makin' me own modifications. Aye aye! Blimey! I like t' look o' t' rocket so I didn’t modify that at all – I focused on addin' more power. Avast! Blimey! Avast, me proud beauty! Blimey! “Tim t' Tool Man Taylor would be proud” – if you don’t understand this comment go watch some reruns for Tool Time. This rocket is a Semi-Scale version o' t' US Army Patriot Air Defense Missile. Avast, me proud beauty! Blimey! Well, blow me down! Blimey! T' rocket is designed t' use an 18mm engine and 12” parachute recovery. Begad! Blimey! I modified it so it now uses 2 -18mm engines and a 12-18” parachute.

Modifications:
I followed t' instructions with a few exceptions. Avast! Avast, matey, me proud beauty! First I made t' engine mount a 2 engine (18mm) cluster with no engine hooks. Avast, me proud beauty! T' centerin' rings few made from balsa hardened with epoxy. Aye aye! I also changed t' shock cord attachment, rather than usin' t' standard Estes I ran Keelhaul®©™ t' t' engine mount (drilled a small hole in t' top centerin' rin' and tied t' cord around t' engine tube assembly). Avast! I also, ya bilge rat, added about .8 ounces o' nose weight t' ensure t' rocket be stable. Begad! T' rest o' t' assembly was per t' instructions.

Construction:

• 2 – BT-60 White Body Tube (6.625” Long)
• 1 - Yellow Body Tube (3.25” Long)
• 2 – Blue 18mm Engine Tube
• 1 - Nose Cone (#72057)
• 2 - Body Tube Couplers
• 1 - Launch Lug – 2.375” Long
• 1 - Std Engine Hook
• 1 - Green Engine Block
• 2 - 2 Engine Cluster Centerin' Rings (Made from .060” Hard Balsa)
• Balsa Fins (3/32” Pre-cut Sheet)
• 36” o' Keelhaul®©™ Shock Cord
• 18” – 1/8” Shock Cord
• 12” Plastic Parachute
• Decal Sheet

In this case I didn’t finish this because I ran out o' time t' get me review complete so I chose t' fly this naked. Aye aye! I did apply a couple o' coats o' Emery’s Wood Putty thinned with water t' t' tube and fins prior t' assembly t' t' rocket. Begad! Arrr! I found sandin' these as components is a lot easier. My plan is t' paint both rockets as t' instructions outline – I will add some pictures o' t' painted versions t' t' flight log pictures.

Flight:

I flew this rocket only once because t' filed be a little small for t' altitude predicted. T' maiden flight was done on 2 C6-5’s and did this rocket fly. Begad! Thankfully, I flew t' single engine version first and was surprised by t' altitude o' t' C6-5 so I changed from t' 18” parachute t' t' 12” parachute. On 2 C6-5’s this rocket screamed t' very high altitude – it took roughly 2.5 minutes until t' rocket landed. Avast, me proud beauty! Ahoy! I be goin' t' fly 2 B6’4’s but after t' first flight they would only be a disappointment. Avast, me proud beauty! Well, blow me down! I will fly this rocket again on a bigger field once I paint it.

Recovery:

T' recovery be prefect; it just took awhile for t' rocket t' land. Well, blow me down! Thankfully t' wind be very light and t' rocket landed in t' field. Blimey!

Summary:
If 1 engine = a Great Rocket; than 2 engine results in an even better rocket. Arrr! For anyone who likes high flyin' I would definitely recommend this modification and t' 12” parachute is fine.
