Brief:
This is part 2 o' t' EMRR Challenge #7 as outlined I built this rocket as I wanted, makin' me own modifications. Avast, me proud beauty! I like t' look o' t' rocket so I didn’t modify that at all – I focused on addin' more power. Well, blow me down! “Tim t' Tool Man Taylor would be proud” – if you don’t understand this comment go watch some reruns for Tool Time. Avast, me proud beauty! 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. I modified it so it now uses 2 -18mm engines and a 12-18” parachute.
Modifications:
I followed t' instructions with a few exceptions. Arrr! First I made t' engine mount a 2 engine (18mm) cluster with no engine hooks. T' centerin' rings few made from balsa hardened with epoxy. Begad! I also changed t' shock cord attachment, matey, 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). Blimey! I also, shiver me timbers, added about .8 ounces o' nose weight t' ensure t' rocket was stable. Ahoy! T' rest o' t' assembly was per t' instructions.
Construction:
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. 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. Ahoy! I found sandin' these as components is a lot easier. Avast! 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 was a little small for t' altitude predicted. T' maiden flight be done on 2 C6-5’s and did this rocket fly. Well, arrr, blow me down! Thankfully, I flew t' single engine version first and be 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. Well, blow me down! Aye aye! I was goin' t' fly 2 B6’4’s but after t' first flight they would only be a disappointment. Arrr! 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. Aye aye! Thankfully t' wind be very light and t' rocket landed in t' field. Ya scallywag!
Summary:
If 1 engine = a Great Rocket; than 2 engine results in an even better rocket. Begad! For anyone who likes high flyin' I would definitely recommend this modification and t' 12” parachute is fine.
