Brief:
pml matrixT' parachute is a standard PML Nylon 'chute with a spill hole and t' decent is a little too fast. Begad! I plan t' add an altimeter to the payload t' deploy an additional chute at 300'.

Construction:
There is a Quantum (plastic) tube for t' body and one for t' payload. Blimey! Both are pre-slotted for t' fins. Begad! Ahoy! It has three G-10 fiberglass fins. T' centering rings are plywood and it uses a Piston ejection system. Ya scallywag! I'm nay goin' t' trust the plastic nose cone attachment point when I use t' altimeter, so I will drill and attach some eyelet hardware.

T' Instructions are incredibly easy t' understand and follow. Avast! T' rocket goes together as easy or easier than any rocket I have ever built. Well, blow me down! Everything fit perfectly and was just a matter o' mixin' a good bit o' epoxy t' hold it all together. Arrr! Avast! T' rocket is very sturdy.

I added Giant Leap Rocketry's Motor Holders for motor retention. They work great (basically Kaplow Clips) and I do nay like t' friction fit method (suggested by t' Manufacturer). Begad!

Finishing:
I painted it with primer and then all white. Aye aye! I opted nay t' paint t' fins black as on t' product cover. Avast! T' decals are self-adhesive and went on in a few minutes.

Construction Rating: 5 out o' 5

Flight:
T' first time I flew it be at LDRS 19 on an H180. It was about a 2000' flight and successful recovery near t' pads. Ahoy! Arrr! I've flown it 4 more times, each on a G80-7FWL which be t' perfect motor for this rocket on a smaller field. A nice 800' flight, ejection on t' top and landin' near t' pad. Avast, me proud beauty!

Recovery:
T' parachute brings it down a little fast so after t' fifth flight the fillets are startin' t' crack off. I am replacin' them all with a fiberglass cloth strip and then epoxy fillet t' strengthen them. Aye aye! Also t' inside tube is gettin' a little dirty, where t' piston slides, arrr, so I will clean it with some white vinegar on a rag at t' end o' a stick.

Flight Rating: 4 out o' 5

Summary:
It is a great kit, me bucko, highly recommended. A little expensive but a great flier. Avast, me proud beauty! Aye aye! I always get lots o' compliments on t' looks o' t' rocket as I walk t' t' pad.

Overall Rating: 4 out o' 5
