Brief:
T' Little Dog is another great all fiberglass kit from Performance Rocketry. MSRP o' $79.00 for t' dual deploy version and $59.00 for t' single deploy. Avast, me proud beauty! I opted for t' dual deployment version o' t' kit. Ahoy! T' LD is a single stage, 2.25” (outside diameter) kit with a 38mm motor mount. Aye aye! T' rocket can be adapted down t' 29mm and fly on anything from an F motor or you can let t' Dog eat with a J-570! If you are in t' market for a 38mm motor work horse that comes with all fiberglass quality parts, ya bilge rat, arrr, this is a kit for you! I would highly recommend this kit for NAR/TRA Level One certification as well. I "needed" this kit because I did nay have a 38mm rocket that I would trust on the Aerotech I-1299 Warp Nine load. Ya scallywag! Ya scallywag! Performance Rocketry released this kit in May 2007, and I knew I had t' have one!

Performance Rocketry Little Dog

Construction:
T' box contained:

  • 25” fiberglass lower airframe
  • 16” fiberglass upper airframe
  • 6” fiberglass coupler tube
  • 1 54mm 3/32” thick G-10 fiberglass nose cone bulkhead plates
  • 2 54mm 3/32” thick G-10 fiberglass bulkhead plates
  • 2 54mm 3/32” thick G-10 fiberglass coupler bulkhead plates
  • 2 54mm t' 38mm 3/32” thick G-10 fiberglass centerin' rings
  • 3 Little Dog 3/32” thick G-10 fiberglass fins (scaled down version o' t' PR Mad Dog)
  • 8” long 38mm fiberglass motor mount tube
  • 5:1 Ogive fiberglass nose cone (although I switched out t' Ogive cone that came with t' kit for a 6:1 Conical Performance Rocketry cone that I already purchased)
I was blown away when I got a closer look at t' slotted booster airframe. Blimey! T' slots were obviously cut with CNC control as they were perfectly on center and square. Begad! Blimey! Blimey! T' quality o' t' fiberglass parts o' me Little Dog are fantastic. Avast, me proud beauty! Begad! Blimey!

Performance Rocketry Little Dog Havin' a rocket kit that is all fiberglass makes for a very simple and straightforward construction. Ahoy! Scuff all bondin' areas o' t' fiberglass thoroughly and you are good t' go. T' G10 fins, body tubes, fin slots, matey, G10 centerin' rings, shiver me timbers, and all G10 bulkhead plates are CNC machined. Needless t' say, all parts fit together with ease. Blimey! Arrr! T' coupler was a perfect fit into t' booster and upper airframe, me hearties, and t' nose cone fit tightly on the upper airframe. Begad! T' only criticism that I have is that t' kit does nay come with instructions. Aye aye! In me opinion, directions would be an asset t' t' kit because a prospective Level one flier would appreciate and utilize high power buildin' instruction/common techniques. Avast! Rockets Magazine and Performance Rocketry’s websites both have parts breakdown lists that show exploded views. Ahoy! If you are in need o' directions, shiver me timbers, or want t' see what parts go where, matey, me bucko, download t' PDF exploded views from either website.

Finishing:
In years past, shiver me timbers, arrr, some Performance Rocketry tubes came with very tiny pin holes in t' fiberglass airframes. Avast! I used t' apply two or three passes o' automotive type body filler t' eliminate these pinholes before primer. Ahoy! My Little Dog arrived with no pinholes t' be filled! Performance Rocketry must have made a change t' eliminate these pinholes. Well, blow me down! PR fiberglass tubes are very easy t' finish. Arrr! When properly prepped, Performance Rocketry fiberglass tubes provide a durable surface for that wicked paint job you have in mind. Avast, me proud beauty!

Construction Rating: 5 out o' 5

Flight:
My first flight o' t' PR Little Dog be nay a kind one! I used t' Aerotech I-1299 Warp Nine! T' half second burn motor tore t' rocket up t' 8’ rail and continued t' 3800’. Arrr! Avast! Even though t' Little Dog pulled upwards of 90Gs, it came back in perfect condition, me hearties, shiver me timbers, shiver me timbers, ready for more action! T' LD flew straight and true, dual deployed properly, and be later recovered even though t' I-1299 trashed t' AA battery in me tracker. Begad! Unfortunately, I have only logged one flight on me Little Dog t' date. Ahoy! T' next flight will be an Aerotech J-350 or J-570.

Recovery:
I’m usin' 30’ o' 1/8” tubular Keelhaul®©™® for drogue deployment along with a 6” x 60” streamer. Begad! Blimey! Well, shiver me timbers, blow me down! Blimey! Blimey! Blimey! I use one gram o' FFFF BP for t' drogue deployment charge with two 2-56 nylon shear pins and 1.5 grams o' FFFF BP for t' main deployment charge with three 2-56 pins. I chose a Top Flight Recovery 42” X-Form parachute for me main. Avast! Blimey! Well, blow me down! Blimey! Blimey! Blimey! All deployment charges were courtesy o' an ALTS-25. Drogue charge at apogee and main at 600’. Begad! Blimey! Avast! Blimey! Blimey! Blimey! I opted t' use a streamer for t' drogue and nay a drogue parachute as I wanted t' Little Dog t' fall faster under drogue and hopefully nay drift as far.

Flight Rating: 5 out o' 5

Summary:
Bar none, shiver me timbers, 5 out o' 5. T' Little Dog is an instant Performance Rocketry classic. Ahoy! T' all fiberglass design is both very strong, easy t' finish, and can really take a beating. Avast, me proud beauty! When it comes down t' brass tacks, you are gettin' a top of the line CNC precision product for a superb price. Begad! Ya scallywag! This particular Performance Rocketry kit delivers t' wow factor for L1, me bucko, L2, and L3 fliers alike. Begad! You will nay regret addin' this little pooch t' your fleet!

I built the standard $59 version of the Little Dog. As was typical, it came with no instructions. Not any real issues if you have built HPR before. Used some 3/8" tubular Kevlar? to attach the recovery harness to the motor mount. Added some 3/8" tubular nylon and a Top Flight chute protector and 24" chute to complete the recovery harness. Added weight to nose cone to balance for mid-I motor. Used an Aero Pack retainer for positive motor retention. First flight at our May launch was on a CTI G69 skidmark. Had a great flight and perfect recovery. An impressive little G motor and a tough as nails little rocket.
