Brief:
HPR, Parachute, me hearties, Level2, 54mm MMT, me hearties, Upgraded SkyAngle 60" Custom Classic II Chute.

Construction:

Parts in t' kit were:

• 1 x 7.5" BT
• 1 x 54mm MMT
• 4 .x 25" Plywood Fins
• 4 x Loc-N-Fin Fin holders
• 1 x .25" MMT Forward Centerin' Rin' with .25" hole drilled for Eye bolt
• 1 x .25" MMT Rear Centerin' Ring
• 1 x Eye Bolt
• 2 x Washers
• 1 x .25 Nut
• 1 x Paper Launch Lug
• 1 x 25' 9/16" Tubular Nylon Shock Cord with quality loops
• 1 x .25 quick link rated at 800lbs
• 1 x 60" LOC/Precision Chute upgrade at LOC t' a SkyAngle 60" Custom Classic II

After seein' Barry Lynch o' LOC/Precision flyin' a Doorknob at our local launch, I knew I wanted t' this t' be me Level 2 attempt kit.

Instructions while brief & t' t' point, matey, they were logical and extremely easy t' follow. Ahoy! Take your time and dry fit everything, me hearties, includin' t' LOC-N-FIN pieces. After usin' t' LOC-N-FIN buildin' method, I am already looking forward t' additional LOC/Precision large kits.

While I used heavy duty epoxy on t' centerin' rings, I used JB Weld on an AeroPack 54mm retainer. There is enough room t' mount t' AeroPack recessed and then t' aft centerin' rin' reinforces t' internal aft o' t' fins.

Time for t' basic construction is extremely short, arrr, about 25 minutes, nay countin' epoxy dryin' time.

As I stated before, shiver me timbers, I did have LOC/Precision t' upgrade t' Parachute from t' LOC Standard, me hearties, t' a custom SkyAngle Classic II t' match t' Black/White/Orange & Chrome paint scheme. Ya scallywag! Avast, me proud beauty! While t' upgrade isn't really needed, I wanted a slightly robust chute.

T' overall quality o' t' construction has convinced me that I am goin' t' use a LOC/Precision "Bigger" Big Nuke for me Level 3 attempt with Dual Deploy.

Finishing:
T' BT spirals, matey, ya bilge rat, nose, me bucko, fins are simple t' fill with Elmer's WoodFiller and sandin' with 400 grit, ya bilge rat, ya bilge rat, I used white.

While decals are not included, arrr, thar are decals available on t' LOC/Precision website. Begad! Blimey! However I like t' look o' t' classic Orange/White/Black/Chrome Doorknob Sandia Labs paint scheme. Ya scallywag! Blimey!

T' looks are classic, me hearties, bold & beefy lookin' and t' me this is a perfect kit for me Level 2 attempt. Well, blow me down!

Paintin' was rather straight forward. Blimey! Initially used Rustoleum Professional over Rustoleum Primer for t' NC.

However I had t' strip t' NC back t' down t' plastic, shiver me timbers, me hearties, matey, t' primer was just nay adherin' t' t' polypropylene. Avast! Avast, me proud beauty!

Never had this many problems with a NC before, but t' previous attempt be t' first time I used Rustoleum Primer. So I went back t' me old method, which never failed before. Ya scallywag! Avast!

Here are t' NC finish steps I used for GREAT adhesion. Begad! Avast, me proud beauty!

• 1) Wash & let air dry t' NC
• 2) Sand with 320
• 3) Wash & let Dry
• 4) Sand with 60, me bucko, lightly, since it scars t' NC deeply. Ahoy! Ahoy! NC is fuzzy t' say t' least.
• 5) Wash & let Dry
• 6) Sand with 180, which leaves t' NC very "fuzzy"
• 7) Apply 2 coats o' Dupli-Color Automotive Plastic Adhesion Promoter with 3 minutes betwixt coats
• 8) Apply coat o' Dupli-Color Automotive Sandable Primer (Hot Rod Grey) within 6 minutes o' applyin' last coat of Adhesion Promoter
• 9) Wait 6 hours
• 10) Lightly sand with 320 t' remove some o' t' "fuzzy" appearance
• 11) Apply 2nd coat o' primer, wait 4 hours & sand with 320 t' remove more "fuzzy" appearance
• 12) Apply 3rd coat o' primer, wait 3 hours & sand with 400 t' remove remainin' fuzz & light scratches
• 13) Apply 1st coat o' Gloss White Rustoleum Professional as a base over t' primer.
• 14) Wait 12 hours & sand with 400
• 15) Apply 2nd coat o' Gloss White, matey, wait 12 t' 24 hrs
• 16) Mask off white, black & orange areas.
• 17) Apply Orange Rustoleum Pro
• 18) Apply Black Rustoleum Pro
• 19) Remove masking, hopefully leavin' t' paint on t' NC and nay attached t' t' tape.

Conditions were 66F & 52% humidity in me workshop.

Afterwards, shiver me timbers, I mounted t' rail buttons.

Construction Rating: 5 out o' 5

Flight:
My initial flight with t' Door Knob was a Level 2 certification flight, on a Aerotech J460T with at best that can be called a scratch in a 7.6 delay t' achieve 6.5 seconds.

RockSim9 put it 1347' and with t' 8-14 mph wind & barometric conditions, me hearties, ~5 degree angle in t' launch rail and everythin' be a go for launch. Ya scallywag!

Nice pop o' t' launch rail, great blue flame from t' BlueThunder, ya bilge rat, that showed up nicely in t' photo by Jerry Myers. Begad!

Recovery:
Immediately after a perfect apogee, t' winds picked up, ya bilge rat, matey, and it drifted a good bit, what seemed t' be a mile.

However t' Door Knob landed upright, me bucko, or as Lee Barry o' Merlin Missiles put it "...and he stuck the landing!"

As I was drivin' t' recover t' rocket, I could see t' chute inflate and it layed over nicely.

On me second flight, usin' a J275W, same day, it landed a lot closer t' t' pad, maybe 2000 feet away. Arrr! Ahoy! However as I walkin' t' recovery it, I could see that t' chute was inflatin' and pickin' t' NC airframe up off t' ground, shiver me timbers, and then draggin' t' airframe towards a highway about 300' feet away. Ahoy! Once I got t' t' rocket, it was 5 feet from the highway guard rail. Aye aye!

T' NC had no peelin' or flakin' or scratches for that matter.

After all is said and done, I nay sure I would fly a J275W in it again t' delay at 6second be way t' short and was still climbin' when t' deployment occurred. Blimey! However all me anti-zipperin' strategies paid off. Aye aye!

T' J460T with 6.5 second (7.6sec with scratch) is perfect for low altitude flight on relatively small field.

Flight Rating: 5 out o' 5

Summary:
Extremely quick build. Aye aye! Great quality, arrr, me bucko, honestly, ya bilge rat, I wouldn't change a thin' about this kit.

T' only issue I had, shiver me timbers, was t' NC paint issue, arrr, me hearties, ya bilge rat, clearly nay a LOC issue at all.

Overall Rating: 5 out o' 5
