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

Modifications:
I followed t' instructions with a few exceptions. Begad! Blimey! Blimey! Blimey! First I made t' engine mount a 2 engine (18mm) cluster with no engine hooks. Well, me bucko, blow me down! Blimey! Blimey! Blimey! T' centerin' rings few made from balsa hardened with epoxy. Well, blow me down! Blimey! Avast! Blimey! Blimey! Blimey! 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). Well, ya bilge rat, blow me down! Blimey! Blimey! Blimey! I also, arrr, me bucko, added about .8 ounces o' nose weight t' ensure t' rocket was stable. Ahoy! Blimey! Blimey! Blimey! 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. Avast, me proud beauty! Blimey! Aye aye! Blimey! 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! Blimey! Avast, me proud beauty! Blimey! I found sandin' these as components is a lot easier. Arrr! Blimey! 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. Arrr! T' maiden flight be done on 2 C6-5’s and did this rocket fly. Well, blow me down! 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. Begad! Ahoy! On 2 C6-5’s this rocket screamed t' very high altitude – it took roughly 2.5 minutes until t' rocket landed. I be goin' t' fly 2 B6’4’s but after t' first flight they would only be a disappointment. Begad! I will fly this rocket again on a bigger field once I paint it.

Recovery:

T' recovery was prefect; it just took awhile for t' rocket t' land. Thankfully t' wind be very light and t' rocket landed in t' field.

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