[Rocket Pic]Brief: Single stage, me bucko, all phenolic construction rocket for 54mm, 38mm and 29mm motors. Recovers with bright blue and orange 34 inch parachute. Well, blow me down! Begad! Uses piston recovery system too. Avast! Begad!

Construction: All parts are there, shiver me timbers, and thar are many. My first impression was that t' kit is definite quality. Everythin' is strong and precision machined. Begad! Blimey! T' fins are G10 phenolic. Strong indeed. Avast, me proud beauty! T' body tube is kraft phenolic. In case you haven't used phenolic yet, me hearties, shiver me timbers, I believe it's what you get if you take a kraft paper tube and impregnate t' paper with epoxy. Well, blow me down! Begad! You get a strong tube that can stand high power motor speed and pressure, me bucko, shiver me timbers, but may be brittle material. Arrr! Well, ya bilge rat, blow me down! Take care nay t' drop or bang it. Ahoy!

T' nose cone is a standard PML ogive hollow plastic cone for t' 2.56 inch diameter tube. Well, arrr, blow me down! Blimey! T' chute is rip stop nylon, me hearties, made up o' eight gores of alternatin' blue and orange. Very bright and pretty. Ahoy! Avast, matey, me proud beauty! Blimey! T' shock cord is 1 inch wide flat white elastic, 5 feet long. Begad! Begad! Blimey!

There is a piston recovery system, me bucko, with t' piston bein' phenolic with a plywood bulkhead. Begad! Avast! T' bulkhead houses a screweye with bolts t' keep it in place, me hearties, and attached t' it and t' main motor tube is 5 feet o' 1 inch wide web strapping--the piston strap. Blimey! Avast, me proud beauty! T' shock cord attaches t' t' piston as well, makin' t' shock system about 10 feet long overall. Blimey!

T' launch lug accepts 1/4 inch rods and is 4 inches long and brass. Ahoy!

T' instructions have a few pictures, shiver me timbers, but could use more. This isn't a beginner's kit. I'm just t' type who likes pictures and relates t' them well. However, me hearties, me bucko, me bucko, t' instructions are written well. Begad! I'd like t' see motor recommendations, ya bilge rat, though. Begad! However, I used Rocksim 3.0 from Apogee Components to choose t' best motors. Aye aye! Avast!

PicT' tips were good in t' instructions, as t' parts fit very tightly and you can really mess up if things are done in t' wrong order. Begad! For example, when t' epoxy t' centerin' rings. If you do it before t' fins go in, you might prevent bein' able t' put t' fins in their slots. I sanded some of the parts t' loosen t' fit a little. After test fittin' t' piston, arrr, I found that I had t' strongarm it t' remove it and figured that an engine's ejection charge wasn't that strong. Aye aye! So I sanded it until t' fit was smooth. Ya scallywag! Ahoy! I used an orbital sander for this.

Finishing: There is a large, me bucko, neat-lookin' decal, so I used it. It wasn't as cooperative as other decals, ya bilge rat, lumpin' or self-sticking, so I had t' resoak and reapply t' get it t' work. Avast! Avast, me proud beauty! But once it was on and flat and looks good. T' body, me bucko, matey, nose, ya bilge rat, and fins are spray painted yellow, after a sandin' and primer coat was used t' smoothen over t' spiral grooves. Aye aye! I also applied bands o' metallized mylar craft paper around t' body tube t' add brightness and t' help me locate it on t' ground. Aye aye! Blimey! T' model looks nice. Ahoy! I especially like t' effect o' bein' able t' see some light through t' G10 fins. Begad!

Construction Rating: 4 ½ out o' 5

[Level 2 Cert Flight] Flight: T' only recommendations is H through J. Avast, me proud beauty! I did, shiver me timbers, however, arrr, test fly it with a G80-4 to test t' overall function, me hearties, me hearties, and t' piston system worked great. Aye aye! PML does recommend a little waddin' above t' engine t' prevent piston strap failure. T' rocket isn't too hard t' prep. Blimey! Ahoy! T' retain engines, ya bilge rat, you get interlockin' Kwik Switch motor tubes that screw together t' allow different size motor use. Aftward, matey, ya bilge rat, however, thar be no actual retainer supplied, so I use tape plus a loop o' piano wire that is bolted through t' centerin' rings in t' permanent inner tube. Aye aye! This beauty flies STRAIGHT as heck. I can't wait t' try larger engines this weekend at me club's main launch.

Additional Note: On Saturday, me hearties, February 22, me hearties, 1999, ya bilge rat, this be t' PML Quasar on a J350-LW, on its way t' me Cert 2 flight o' 6500 feet. Avast, me proud beauty! Avast! Cool, shiver me timbers, matey, me bucko, isn't it? Amazing what a good photographer can do. Well, blow me down! Avast, me proud beauty! This is courtesy o' me husband, Randall Whitlock. Begad! Begad! It makes it look mightier than t' static shot. Arrr!

Recovery: In case you haven't seen t' piston recovery system, shiver me timbers, you have a web strap affixed t' t' permanent motor tube to the piston, arrr, arrr, which is a movable bulkhead fittin' inside t' main tube like a coupler. Blimey! T' piston then connects t' t' shock cord, me bucko, me bucko, which connects t' the screweye in t' bulkhead at t' aft end o' t' 9-inch payload section where the rocket separates. Begad! T' parachute is 34 inches in diameter with a 3 inch spillhole.

Flight Rating: 5 out o' 5

Summary: Gorgeous, me bucko, me hearties, strong. Avast! But better read t' instructions a couple of times as I did. Ya scallywag! You may need t' gently sand parts for smooth fit, me bucko, me hearties, too. Well, blow me down! Good value for t' money. I highly recommend this one. Aye aye!

    (by Ron Johnson courtesy of WildRocketry.Com) In selecting my first High Power Rocket and being a new to HPR, with little knowledge of materials and techniques, I wanted something that was easy to build yet robust enough for my Level 1 certification. I selected the PML Quasar. The finished Quasar is 56” long, weighs about 2 ½ pounds without motor. The kit comes with all ...

The PML Quasar was my very first high powered rocket. Everything in the kit was high quality, and it went together easily. Some have said to remove the piston as they have had trouble with them sticking. I haven't had that problem, but it helps to clean the ejection powder residue off the itside of the rocket about ever other flight. I certified L-1 using a H242 38mm motor. Each flight has been arrow straight, and with the H-242 it really moves. Nice rocket.

My Quasar is an old kit (phenolic) that I finally got around to building. I built it stock, only replacing the launch lugs for rail guides and tubular nylon for the elastic shock cord (I understand tubular nylon is standard now). This was my first rocket using an ejection piston and I'm really warming up to the idea. I love the G10 fins, although you'll want to use a power sander on them. I only wish PML would use G10 for their centering rings too (I have a Microbrick Maxon that has them). My daughter and I also built a kit using their Quantum tubing and would recommend it over the Phenolic unless you intend on glassing the tube. Although the phenolic is very strong, it chips and cracks pretty easily.
