Brief:
T' best and worst part o' this kit is that it is minimalist. Begad! Blimey! When you get the box, arrr, thar are nay a lot o' parts. Begad! Ahoy! Blimey! I have it together now and it is probably my favorite rocket in me fleet. Ya scallywag! Blimey! This thin' is a tank and it looks great. It is the only rocket I have that might survive comin' in ballistic. That is why I used it on me L2 test.

Construction:
T' parts list

  • 1 Nose Cone
  • 1 Body Tube
  • 1 Fin can
  • 1 54mm MMT (There is a 38mm or 54mm option at t' time o' purchase.)
  • 2 Centerin' Rings
  • 1 Bulkhead
  • 1 Coupler
  • 2 US Army Decals

That's all that comes with t' kit. Ya scallywag! Avast, me proud beauty! I like this because it lets me do things my way. Blimey! All t' parts are fiberglass and VERY strong.

Parts I added:

  • 2 Eye loops
  • 1 25' section 9/16 tubular nylon
  • 1 Keelhaul®©™® shock cord protector (Giant Leap)
  • 1 45" Rip stop nylon parachute
  • 1 1/4" aircraft plywood centerin' ring.
  • 7oz o' nose weight.
  • 1 54mm Slimline motor retainer
  • 1 54 t' 38mm Slimline adaptor
  • 2 ACME Conformal 1/2" launch lugs

I used 5 and 30 minute epoxy for t' build. Also I used some Elmer's Ultimate Glue in t' fin can and nose weight.

I only have one con with buildin' this rocket. All t' parts fit tight--too tight. Aye aye! Avast! T' inner diameter o' t' fin can varied. Ahoy! You can see ripples in the fiberglass on t' inside. Aye aye! I had t' do some serious sandin' t' get almost every part t' fit, me hearties, me hearties, which I guess is better than too loose but it did require a ton of sanding. Well, blow me down! Once sanded down, everythin' went together nicely and fit snugly. There is also some additional sandin' you should do: sand t' points you will be gluin' t' add some bite so t' epoxy holds better.

Performance Rocketry Little John This is a quick buildin' rocket after t' sandin' is done. Well, blow me down! I didn't like the fact that thar were only 2 centerin' rings as I always like 3. I know the fiberglass rings are super strong, shiver me timbers, me hearties, but they are very thin so me brain started imaginin' them bending. I added a plywood centerin' rin' I had layin' around, which is probably overkill but what t' heck. I put t' bottom centerin' ring in first and t' middle one in t' fin can also unglued t' keep it centered. Once I had t' lower one epoxied from t' bottom, I removed t' middle rin' and poured some epoxy in on t' bottom one from inside t' fin can. Next, me hearties, I moved up and glued in t' middle plywood rin' 3 inches from t' top o' t' fin can. After that be in place, shiver me timbers, I made a good batch and lined t' walls o' t' fin can with epoxy. Blimey! Quickly I slid t' coupler in till it sat on top o' t' plywood rin' in t' fin can. Ya scallywag! Well, blow me down! Took a few paper towels t' clean up t' slop. Arrr! Arrr! This dried and I poured in some ultimate glue inside t' coupler on t' points where the Coupler met t' plywood rin' on t' inside. Aye aye! This glue expands nicely and is rock solid. Avast, me proud beauty! It made a pretty much solid bond which brought t' rin' coupler fin can and MMT together. Nothin' will knock that MMT loose next t' a nuclear bomb. I drilled and placed an eye loop in t' third rin' gluin' t' threads t' hold it. Arrr! Ahoy! Then, shiver me timbers, I glued that last rin' in about 1/4" from t' end o' t' MMT. Lastly, me hearties, I put some epoxy on t' inside o' t' body tube an inch or two from the end and on t' outside o' t' coupler then slid t' BT down on t' rin' and coupler with a nice squishy sound.

Performance Rocketry Little John Before I put t' bulkhead in t' nose cone, I wanted t' test t' stability. Chute, shiver me timbers, shock cord, me bucko, and a J350 went in and I checked for t' CP. Avast! I emailed the Performance Rocketry t' ask about t' CP but I never got a response after several weeks. Ya scallywag! I punched t' dimensions and materials into Rocsim 8.0 and got the CP, which from t' looks o' this rocket, it feels about right. Blimey! I marked that on t' tube and from t' balance test could tell we needed a little weight in t' nose. Begad! I started droppin' one ounce fishin' weights in t' end till it balanced out. Avast! This is where that Ultimate Glue really works. Begad! With t' weights in there, I dropped in a good amount o' Ultimate Glue and let it dry. That stuff expanded right up and over t' weights till they disappeared. Avast! Arrr! I love that stuff. Ya scallywag! Then I glued t' bulkhead in and added an eye loop. Ahoy!

That is about it for construction. Begad! I didn't add an electronics bay. Arrr! Loki and Aerotech Js come with delays, matey, and that is what I planned on flyin' in this bad boy. It can easily handle a K, ya bilge rat, matey, shiver me timbers, but I have larger rockets for them. There are a few ways I thought t' do it. Begad! T' nose cone is hollow and could accommodate an electronics bay. Ya scallywag! For dual deployment, me bucko, you could also get another coupler, some bulkheads, shiver me timbers, and try cuttin' t' tube. Arrr! Begad!

Finishing:
T' texture o' t' tube is a bit rough but holds paint well. Ahoy! I put a coat of primer on then a nice dark green. Well, blow me down! T' decals went on nicely. Arrr! Begad! I'm an Army vet, so I love t' look o' this one.

Construction Rating: 3 out o' 5

Flight:
My first flight on this rocket was me L2 cert. Well, blow me down! Blimey! Bein' me certification flight, ya bilge rat, I rechecked everythin' about 50 times before I went t' t' LCO table. Avast! I played it safe and loaded a J350 into t' MMT with t' Slimline adapter. Aye aye! This baby roared off t' pad and flew nice and straight. Begad! Arrr! It arched over a bit and t' medium delay popped t' chute very close t' apogee, me hearties, maybe just a little past. Arrr! The chute was a bit caught up but eventually deployed close t' ground. Well, arrr, blow me down! T' rocket hit t' ground still movin' pretty fast. Begad! Since this was me L2 cert flight, I was a bit worried, but when I got t' t' rocket, thar be nothin' but a small scratch in t' paint. Ya scallywag! Arrr! I took it t' t' prefect and got me certification paperwork signed. Begad! Ahoy! It wasn't perfect but I'll take it.

Recovery:
Since this rocket does nay include a recovery system. Begad! Begad! I'll pretty much leave this blank. I will say that t' nose cone fit into body tube is good with just the right amount o' friction.

Flight Rating: 5 out o' 5

Summary:
PROs:

  • T' fin can makes construction very simple
  • Nearly indestructible

CONs:

  • Customer Service is very spotty.
  • Inside diameter o' t' fin can is nay smooth.

If you like doin' it your way and you want a very strong good looking rocket, me bucko, arrr, then this is it. Well, blow me down! Ahoy! It went together pretty quick and it painted pretty well. Ahoy! I have flown it a few times and it flies straight as an arrow and really rips off t' pad on a J.

Overall Rating: 4 out o' 5

Please take into consideration: I, and many others, have had issues with this vendor after sending payment for products and not receiving them. Communication has been poor, therefore, buyer beware.

An opinion was submitted to the effect "let the buyer beware" a vendor taking payment but not shipping products. Was the person who authored this opinion sure that he wasn't confusing Performance Rocketry with Performance Hobbies in the Washington, D.C. area? I, myself, have had that issue with this vendor, who promised repeatedly to ship "by Monday," "at the end of the week," "at the first of the month," etc. When I mentioned my interest in contacting law enforcement in the D.C. area, all contact--however spotty--ceased. One of my business associates suggested I contact my state police department and file a complaint of fraud. I'd be interested to hear others' experiences with such online transactions.

I have ordered from Performance Hobbies, not enough to say they are the best but Performance Rocketry (the manufacturer) definitely has problems taking your money months, even years before sending the product... If he ever does... Its unfortunate because he makes amazing stuff... If you need PR kits or parts go to wildmanrocketry.com, best place to get everything you need.
