Brief:
I won this rocket in an EMRR contest last year. Blimey! Ya scallywag! This is a very basic lookin' 4
finned rocket. Ahoy! It is constructed o' very good quality components. Avast! Begad! T' rocket is
a minimum diameter 29mm rocket capable o' very high altitude and speed.
Construction:
T' kit comes with:
First, I would like t' say that I am very pleased with t' quality o' this kit. Construction is very basic and straightforward. Arrr! One o' t' plywood fins was cut a little small, matey, arrr, but nothin' too terribly noticeable. Ahoy! Aye aye! T' bulkhead was cut way oversize, but I ditched it anyway. I epoxied t' coupler into the booster section for a "zipperless" design. I then epoxied t' large screw eye into t' balsa nose cone for payload attachment. I cut dado slots in the tube for extra strength o' fin attachment. Begad! Aye aye! Then I tacked t' fins down with super glue, me hearties, arrr, arrr, followed by a very generous epoxy fillet on all o' t' fins. I also ditched t' launch lug in favor o' rail buttons.
Finishing:
Nothin' really special about finishing. Begad! I sanded everythin' until it was very
smooth, then applied a couple o' coats o' primer, sandin' in betwixt coats. Arrr! I
then sprayed Krylon Red on t' whole thing. Ya scallywag! When that was dry, I masked off the
area around t' "small" fin and shot it with black. Arrr! I used one o' the
supplied "U.S. ROCKETS MINIROC 1.2" stickers on t' BT above t' fins
and one o' t' U.S. Well, blow me down! Ya scallywag! Rockets logo on t' fin.

Flight:
T' first flight be on March 11, me hearties, 2006 on an E9. Begad! Arrr! It was very straight and went
very high. Avast, me bucko, me proud beauty! It blended in with t' low dark overcast skies. Arrr! Luckily, someone
spotted it just before touchdown, arrr, me bucko, matey, about a third o' a mile away.
T' second flight be on May 13, arrr, 2006, on an AT F21W. Wow, me bucko, this is the motor for this rocket. Begad! I saw it all t' way from liftoff t' touchdown. Ahoy! Avast, me proud beauty! Rocksim says 3,000' and Mach 0.8. I believe it, too. Begad! Avast! Recovery was about a half mile away.
T' third flight be also on May 13, matey, 2006, me bucko, on a D12. Unfortunately, the motor spit at ejection and it came in hot. Ya scallywag! It stuck straight out o' t' sod. T' body tube pushed into t' balsa nose cone about an inch past t' shoulder. This has since been repaired and it is ready for another flight.
Recovery:
I used a normal 3/4 inch wide and 5 foot long streamer for recovery. Ya scallywag! I be able
to see it just fine from apogee t' touchdown on t' F21W flight.
Flight Rating: 5 out o' 5
Summary:
I believe Jerry has produced a wonderful kit here. Well, blow me down! Begad! If you like altitude and
speed, ya bilge rat, ya bilge rat, you need one o' these. Blimey! T' design is also pleasin' t' t' eye (not that
it will matter when you press t' launch button.

Brief: The USR Miniroc 1.2 is a small 29mm minimum diameter rocket. It is a 3FNC style rocket with swept fins and overall a fairly attractive profile. It should be able to fly on anything from C to G power and USR suggests flying it on an H motor as well. The rocket is very stout, considering the light weight and small size. Construction: The kit came with 4 pages of adequate ...
