LOC/Precision Nuke Pro Maxx

Brief:
T' LOC/Precision Nuke Pro Maxx is a simple, robust high performin' 3FNC mid/high power rocket that can fly on motors as little as an F all t' way up t' a t' largest 38mm J motor that you can fit into t' rocket.

My big reason for gettin' this kick is that I fly a lot o' H and I powered rockets. Arrr! I prefer me rockets t' be light and small as well. Ahoy! My USR Banshee only has a 29mm MMT, me hearties, so that limits just how much I can punish that rocket. I wanted a rocket that I could 'get medieval' on...and t' Nuke Pro Maxx seems t' fit that bill. Ya scallywag! Blimey! Minimum diameter rockets would be ideal but are often very challengin' because they tend t' be visually difficult t' track with their small size, offer minimal payload and recovery space, matey, and limit choices for motor retention. Blimey! T' Nuke Pro Maxx strike a nice balance o' me wants by bein' still quite slender but affordin' t' advantages o' non-minimum diameter rockets.

Construction:
T' parts list:

  • 1 2.26"d ogive plastic nose cone
  • 1 12"l x 2.26"d payload tube
  • 1 22"l x 2.26"d body tube (pre-marked for fins and launch lug)
  • 1 coupler
  • 1 birch plywood bulkhead
  • 1 screw eye
  • 3 1.8" thick birch plywood fins
  • 2 birch plywood centerin' rings
  • 1 10"l x 1.63"d motor mount tube
  • 1 18" nylon parachute
  • 10ft elastic shock cord
  • 1 shock cord mount
  • 1 1/4" launch lug

Openin' t' kit from t' heavy gauge plastic bag with hang tag revealed all o' t' necessary parts and instructions for t' kit. Typical o' LOC/Precision kits, shiver me timbers, t' instructions are on t' thin side. Arrr! Aside from t' instructions found on t' folded header card, me bucko, shiver me timbers, t' bulkhead and shock cord anchor each come with their own instructions. Ahoy! I gave t' instructions a quick "once over" t' see if thar were any potential "gotchas" (there weren't any obvious ones t' me). While t' kit is a pretty simple 3FNC based on t' a quantity o' components, me hearties, builders that are new t' MPR/HPR might struggle through t' minimalist instructions.

T' only thin' that stood out upon inspectin' t' overall high quality o' t' components be that one o' me favorite parts o' a mid- or high-power rocket build had already been taken care o' for me: t' fin slots had already been cut into t' main airframe tube. Aye aye! Avast, me proud beauty! However, I'm sure that thar are many folks out thar who aren't keen on slottin' their tubes so this will probably come as a great reason for them t' consider this kit! Nay havin' t' slot t' tube should noticeably reduce t' build time o' this rocket as well. I did some basic dry fittin' o' all components. Ahoy! Well, blow me down! I be a little surprised t' find that t' centerin' rings and fins required a fair bit o' sandin' t' get a smooth fit without havin' t' force anythin' into place. Arrr! In particular, me hearties, t' fin tabs were all about 1/16" too tall, matey, which left quite a gap betwixt t' fin and t' outside o' t' body tube. Ya scallywag! My Dremel with a sandin' drum came t' t' rescue and had everythin' fittin' quite snug in a matter o' minutes though.

T' leadin' and trailin' edges o' t' fins were rounded usin' an orbital hand sander. Also, holes were drilled in t' body tubes for mountin' rail buttons, vent holes t' relieve internal air pressure, shiver me timbers, and for a nylon screw t' hold t' nose cone in place and leave t' payload bay easily accessible.

Elmer's Probond Wood Glue be used out for t' entire construction, matey, except for t' attachment o' t' shock cord anchor and screw eye. Aye aye! First, matey, I glued and filleted t' forward centerin' rin' onto one end o' t' motor mount. Ya scallywag! I dry fit t' aft centerin' rin' 1/2" from t' opposite end o' t' motor tube and glued t' motor tube into t' main body tube so that 1/2" o' t' motor tube sticks out t' aft end o' t' rocket. Ya scallywag! Begad! Before gluin' t' fins on though, ya bilge rat, I brought out me trusty Dremel with a sandin' drum again t' lightly sand away 1/4" o' t' glassine layer all t' way around t' fin slots so that t' glue could really soak into t' tube. Blimey! Then t' fins were attached through t' wall t' t' MMT usin' a double glue method one at a time. Once they were dry, me hearties, I slid t' aft centerin' rin' off and dribbled wood glue into t' narrow gap betwixt t' tubes along each side o' t' fin tabs. Avast, me proud beauty! A scrap piece o' 1/8" diameter wood dowel was used t' spread t' glue along t' length o' t' fin tabs t' reinforce t' joint t' t' motor tube and main airframe. Begad! T' aft centerin' rin' was glued into place after t' internal fillets were completed. Aye aye! Blimey! External fin fillets were done with 3 or 4 thin layers o' wood glue.

T' screw eye was epoxied t' t' bulkhead usin' 15-minute epoxy with milled fiber mixed in. Arrr! T' bulkhead was glued and filleted 1/4" into one end o' t' coupler with Elmer's Probond. Ahoy! T' coupler was glued halfway into one end o' t' payload tube and set aside t' dry. Begad! Blimey! Some maskin' tape was required for t' coupler t' have t' proper snug fit into t' main body tube.

Perhaps t' most challengin' part o' t' build is epoxyin' t' shock cord anchor inside t' body tube. Begad! After tapin' t' nylon strin' inside t' tube per t' instructions, shiver me timbers, care must be taken t' avoid gettin' epoxy on t' first 3 inches o' t' tube so that it does nay interfere with t' fit o' t' coupler. Avast! I taped a small piece o' wax paper inside t' tube t' make this task much easier. Then I glued a couple popsicle sticks end-to-end t' extend me reach inside t' tube. Ahoy! 15-minute epoxy with milled fiber mixed in be used t' properly adhere t' strin' t' t' inside o' t' body tube. Begad! Well, blow me down! T' milled fiber nay only adds considerable strength, but thickens t' epoxy t' t' consistency o' peanut butter. Blimey! An application such as this is simplified because it reduces t' likeliness o' epoxy flowin' into somewhere unwanted. Avast, me proud beauty! Dippin' t' lengthened popsicle stick into a little rubbin' alcohol helped t' smooth out t' epoxy (to prevent anythin' from catchin' on it durin' recovery ejection) and make sure that it thoroughly covered t' nylon string.

T' last part o' t' build be t' tie t' 10 foot long elastic shock cord t' t' nylon loop and screw eye. Avast! A small loop was tied into t' shock cord for attachin' t' parachute too.

I passed on t' opportunity t' attach t' launch lug, arrr, optin' t' drill a pair o' holes for rail buttons which were mounted once I completed all o' t' paint work.

Finishing:
Wood grain on t' fins be filled usin' Elmer's Wood Filler diluted with water t' make it easier t' apply then sanded smooth with 220 and 320 grit sandpaper. Well, blow me down! T' nose cone was washed in warm, me bucko, soapy water, ya bilge rat, scraped with a razor utility knife t' remove t' excess flashing, and then sanded with 220 grit sandpaper.

T' rocket was then primed with a couple coats o' Krylon (gray and white) primer and sanded smooth with 320 grit sandpaper after t' first coat and 400 grit after t' second.

I attempted t' recreate t' LOC paint scheme. T' entire rocket was painted with 2 coats o' Krylon Gloss White (I wet sanded with 600 grit sandpaper in betwixt coats) and set aside t' dry for a few days. Blimey! Avast, me bucko, me proud beauty! T' body tube be then masked off so t' fins could be painted Krylon Sun Yellow Gloss. Well, blow me down! T' nose cone be painted Krylon Banner Red Gloss then I did a fade with Krylon Plum Gloss.

T' vinyl decals came from Graphix & Stuff. Arrr! I saw their ad in Sport Rocketry magazine and got a quote through their website. Their prices are very reasonable, service is top notch and speedy, matey, and t' decals look awesome. Well, me hearties, blow me down! While t' paint scheme was virtually identical t' t' artwork on t' LOC/Precision website, I came up with me own interpretation o' t' decals.

Flight:
Preppin' this rocket isn't notably different than most other mid- or high-power rockets. Aye aye! Blimey! I clipped a 9" x 9" Nomex® heat shield and used a quick link t' attach t' relatively small but adequate LOC chute and me rocket beeper onto t' shock cord. Begad! T' get this rocket off t' pad, matey, I picked an AeroTech H128W-M along with a 38-29mm motor adapter for t' first flight.

Liftoff was straight up and with rapid acceleration. Well, blow me down! Avast, me proud beauty! In light winds (5-10mph), me bucko, arrr, me hearties, I didn't notice any weathercocking.

Recovery:
Ejection was right at apogee and t' Nuke Pro Maxx came down safely on t' LOC 18" chute. Drift be minimal and I only had a short walk for recovery. Well, blow me down! Our launch site is on undeveloped land and t' nose cone landed on t' road, matey, causin' minor scratches that can be easily touched up. Thankfully t' rest o' t' rocket landed in t' grass.

Flight Rating: 5 out o' 5

Summary:
T' LOC/Precision Nuke Pro Maxx is a kit that can fly on a wide range o' motors due t' t' heavy duty components yet overall light weight o' t' finished rocket. Avast, me proud beauty! I have grown accustomed t' testin' t' upper limits o' me rockets and t' Nuke Pro Maxx should be able t' handle everythin' I want t' throw at it!
