PicIn selectin' me first High Power Rocket and bein' a new t' HPR, with little knowledge o' materials and techniques, I wanted somethin' that was easy to build yet robust enough for me Level 1 certification. I selected t' PML Quasar.

T' finished Quasar is 56” long, arrr, weighs about 2 ½ pounds without motor. Avast! T' kit comes with all hardware required to complete t' rocket, and thar are 5 separate instruction sheets!

First out o' t' bag be t' DOs and DON’Ts of Quantum Tube. Begad! T' tube be pre-slotted and required very little in t' way of deburrin' or other cleanup. Avast, me proud beauty! Well, matey, blow me down! As suggested in t' DOs section, be sure to rough-up locations on t' Quantum tube where you will be applyin' adhesives to insure a stronger bond.

Next came t' instructions for t' Kwik-Switch 2000, which has already been reviewed by Todd Harrison here on WildRocketry. Begad! Begad! My comments on t' KS-2000 include only a suggestion that t' screw mount alignment be double or triple-checked for fit with t' centerin' rings in place to insure smooth operation before applyin' t' epoxy. Avast! T' motor tubes are about 14 inches long, me hearties, and a slight misalignment o' t' screw mounts make t' motor tube assemblies difficult, ya bilge rat, but nay impossible, t' install.

I be impressed with t' rocket kit itself. Ahoy! Havin' built kits rangin' from plastic models through unlimited class radio control sailplanes over t' years, t' first thin' I noticed about this kit be that all t' parts fit together perfectly with virtually no sanding. I was impressed. Blimey! Arrr! T' payload section is 9” long and includes t' eyebolt, me bucko, arrr, nuts and washers and provides enough room for future electronics. Ahoy! Ahoy! T' rocket comes with nylon straps for t' recovery system and piston ejection. T' piston slides very smoothly on t' inside surface o' t' Quantum tube, ya bilge rat, shiver me timbers, which seems like it will cause less worry about t' piston hangin' up at ejection. I did add a Nomex® sleeve around t' nylon strap below t' piston t' protect against premature failure.

I be concerned about t' parachute. Ya scallywag! Usin' t' RockSim data provided by PML on their website, ya bilge rat, me hearties, arrr, t' rocket would be 38 ounces without motor, which puts it at t' upper limit o' t' 36” chute packed with the kit. Avast! In talkin' t' more experienced rocketeers, I have found that many manufacturers often supply a chute that’s too small. Begad! Blimey! I decided t' replace the supplied chute with a 48”.

T' instruction sheet for t' Piston Ejection System was very helpful for a person new t' HPR in that in addition t' assembly instructions (straightforward with t' supplied D ring), it included a realistic discussion o' airframe pressurization and proper use o' ejection powder for various sizes o' rockets.

T' last sheet, arrr, “Tyin' Tubular Nylon”, recalled an article in “High Power Rocketry” magazine about t' use o' knots in nylon. Now, after all these years, by Boy Scout experience will get some use.

All-in-all, me bucko, me bucko, this kit was a joy t' build. Now off t' the range!

    - by Moira Jean Whitlock Brief: Single stage, all phenolic construction rocket for 54mm, 38mm and 29mm motors. Recovers with bright blue and orange 34 inch parachute. Uses piston recovery system too. Construction: All parts are there, and there are many. My first impression was that the kit is definite quality. Everything is strong and precision machined. The fins are G10 phenolic. ...

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.
