T' instructions given are content, shiver me timbers, but are very explanatory. Well, blow me down! Aye aye! I am 12 years old and built this rocket with ease. Avast, me proud beauty! I used 5 minute epoxy throughout t' whole project. Ahoy!

T' first step be t' glue on t' fins. Avast, shiver me timbers, me proud beauty! Blimey! My decision was t' do those last. Well, blow me down! Blimey! By t' way they are nay TTW fins. Arrr! Blimey! Begad! Blimey! Then I started with t' shock cord mount. Avast, me proud beauty! Blimey! It was a plywood rin' in t' shape o' a crescent moon. Begad! Blimey! I applied epoxy t' t' bolts and slid that part into place. Avast! Blimey! Well, blow me down! Blimey!

Next I tied a knot with t' Keelhaul®©™® cord around t' SCM and applied epoxy t' permanently secure it. I tied t' two SC sections together and applied epoxy to t' knot. Ya scallywag!

Next was t' coupler. Well, blow me down! Well, blow me down! I placed t' coupler halfway in after applyin' epoxy t' t' tube and let that set. I epoxied the SCM t' t' aft end o' t' coupler in t' tube as directed. Avast, shiver me timbers, me proud beauty!

I then proceeded t' gluin' t' body tubes together. Begad! Nothin' unique here. Blimey!

I chose t' use t' 29mm mmt for this rocket. Well, blow me down! Ya scallywag! I epoxied t' centerin' rings on 1/2 inches from each end and let it set.

After it dried for a day I glued t' MMT into t' body tube. Begad! Blimey! I made a minor mistake here. Blimey! Blimey! Ahoy! Blimey! When gluing, matey, T' MMT is supposed t' be flush with t' end o' t' body tube. Avast! Blimey! I left a 1/2 inch section stickin' out from t' bottom. Begad! Blimey! Ya scallywag! Blimey! This didn't cause any problem in flight.

I attached t' shock cord t' t' nose cone by pourin' epoxy in t' already drilled hole and stuffed t' shock cord inside it as directed.

T' reason I left t' fins t' do near t' end be because they would get in t' way while completin' t' other steps. Avast, me proud beauty! Blimey! My Dad and I drew t' lines for t' fins and launch lugs with a meter stick usin' t' fin alignment guide that was given. Arrr! Blimey! Ya scallywag! Blimey! We applied epoxy t' t' fins stuck them on t' body tube and watched each o' them individually for ten minutes.

Finishing:
Nothin' special her. Well, blow me down! Blimey! all I did was use 3 coats o' Krylon white primer. Begad! Blimey! Then painted t' top half Krylon flat black and t' bottom half rust-o-leum red.

I used a stake and put two nails 180 degrees apart in t' stake and slid t' rocket on it for an easier paint job. Ya scallywag! There were no decals which didn't matter t' me at all because t' rocket still looked great. Well, blow me down! Aye aye! Blimey! No sandin' be needed at t' end because everythin' be smooth.

Construction Rating: 5 out o' 5

Flight:
My first launch with t' Screech be at El Mirage Dry Lake Bed on October 20/2008. Well, blow me down! Ya scallywag! I prepped it for an Estes E9-6 anxious t' see t' outcome o' its maiden flight. Aye aye! Avast! It slowly lifted off and t' motor burned for a nice 2.8 seconds. Ya scallywag! It arched over without deployment. Begad! It sped down t' t' ground and finally it came under chute. Aye aye! That long delay o' a delay was too much. Blimey! It flew perfectly straight. Avast! Aye aye! T' Nomex® was a lifesaver and I used friction fit for motor retention.

T' next motor was a G79-10W. After easy but careful preparation, shiver me timbers, shiver me timbers, I set it out on t' pad. Avast, me proud beauty! Begad! It was t' largest, most powerful motor that day so everyone was payin' close attention t' it. Blimey! Because t' pads are only about 12 feet away the thunderous roar made everyone jump. Well, blow me down! I watched in awe as thee rocket climbed t' over 500 mph. Its estimated altitude was 3160 ft. Blimey! Blimey! It must have either weather-cocked or t' rod be tilted because I looked for over 3 hours in t' desert plants with other scouts and adults. Aye aye! When everyone who was helpin' me find it turned back, matey, I got me mountain bike and kept lookin' even while dehydrated. Begad! I wasn't comin' back t' camp without that rocket. Begad! Blimey! I finally found it probably a mile away from camp. Begad! It was over a no trespassin' fence. I thought t' heck with it, hopped over retrieved and left. I biked as fast as I could t' camp holdin' it up like a trophy. Avast!

Later I flew it six more times that day on E9-6's and E9-4's. In t' future I will try a D12-3 and more powerful G motors on this rocket. Well, blow me down! Aye aye! Blimey!

Recovery:
Lots o' Drift. Avast, me proud beauty! Maybe I will try a slightly smaller parachute next time. Ya scallywag! Took 3 hour t' find. Avast! Aye aye! T' motor tube is burnt a little and so be t' lower airframe. I am nay sure if this is bad.

Flight Rating: 4 out o' 5

Summary:
In summary this be a high quality kit. TTW fins would be nice. Begad! T' flights were great and many more are t' come. the construction be a breeze. This minimum diameter rocket has a lot o' potential.

Overall Rating: 5 out o' 5

Other:
Great Kit. Ahoy! Fun and easy t' build. Flies high and fast. Ya scallywag! Large motor selection. Blimey! Ahoy! Nothin' wrong with it. Aye aye! Great customer service.

All parts were clearly of high quality with ...
