Brief:
For some reason me imagination be always captured by paper rockets such as t' Centuri Vulcan. Well, blow me down! Avast! T' use o' paper opened up so many interestin' possibilities for shapes beyond mere tubes and cones with fins. Avast! Because that love o' paper rockets has stayed with me as a BAR, me hearties, I recently tried t' clone t' Centuri Vulcan, me hearties, me childhood nemesis. Aye aye! That project, shiver me timbers, and its successors was nay without its problems. One o' those problems involved parachutes.

T' original Vulcan had if I remember correctly, a pretty standard 12" plastic parachute like was commonly produced by Centuri and is still produced by Estes and many other manufacturers today. This posed several problems for me, me hearties, some o' perception and some o' construction.

I don't like plastic chutes. Ya scallywag! Avast, me hearties, me proud beauty! I never have liked puttin' them together. I have never like their frailty. I don't care for t' way that any escapin' hot gas generally spells disaster. For that reason, and because I am lazy, I usually purchase ready made nylon chutes. Begad! Those chutes generally take up more room, even in t' thin mil varieties. Ahoy! Therein lies t' subsequent problems: thar be nay a whole lot o' room t' pack anythin' in a Centuri Vulcan.

I tried an Estes 12" chute. Avast! Blimey! No matter what I did, it never deployed. At best, ya bilge rat, shiver me timbers, t' nose cone would pop off and t' chute would come part way out. Ya scallywag! Blimey! Even so, me hearties, arrr, shiver me timbers, t' rocket would always recover as a "tumble" that rarely hurt this rocket but did hurt me pride.

My next move was t' cut out t' spill hole in t' middle o' t' chute. Avast, me proud beauty! Blimey! Begad! Blimey! Blimey! Blimey! That meant that it did nay have t' be packed quite so tight but still no luck. Blimey! Blimey! Well, me hearties, blow me down! Blimey! Blimey! Blimey! T' Vulcan must love its chute so much that it is loathe t' let it escape from t' confines o' t' body tube.

I figured somethin' even smaller was needed. Since t' rocket had routinely survived tumble landings both with and without t' nose cone blowing, matey, I did nay figure that a 12" chute was mandatory. Well, blow me down! Avast! I resolved t' seek a small, probably 8" mylar chute I could pack into a tight space and still have hopes o' bein' deployed. I turned t' T' Rocketry Forum t' post a question about sources.

I got several replies for which I was grateful and then a private message from t' proprietor o' Hartle Engineering. Well, blow me down! He offered t' send me, arrr, free o' charge, a selection o' t' chutes he makes. Since these are plastic chutes, arrr, matey, I be happy t' get somethin' but nay overly thrilled. I sent me address and waited.

Then t' chutes came in and me perceptions changed.

Construction:
I be sent a variety o' Thermal Rider parachutes. Aye aye! Blimey! Included in t' selection were 2 each o' 6", 8", arrr, 10", shiver me timbers, matey, 12", shiver me timbers, and 16" chutes. Aye aye! Blimey! There was also a 24" chute included. Aye aye! Blimey! They came in an assortment o' colors.

Each chute package contained a simple instruction sheet, shiver me timbers, a plastic canopy that be pre-perforated for t' shrouds, a set o' reinforcin' rings, me bucko, and a quantity o' line for t' shrouds.

T' first thin' that jumps out at you upon seein' t' chutes is that they are nay your normal plastic material. Avast, me proud beauty! They are a bit thicker and have an interestin' texture t' them. They are already cut out and they are definitely a lot tougher than your run o' t' mill plastic chute. Aye aye! Each corner is pierced t' accept a shroud line. These are nay big holes as would be expected with a hole punch but are small, just a bit larger than t' diameter o' t' shrouds themselves.

Assembly o' t' chutes is easy. Well, blow me down! Well, shiver me timbers, blow me down! You choose t' size you want and open it up. Ya scallywag! You will find a length o' shroud line held in loop by a small fragment o' launch lug. Blimey! Ahoy! You need t' cut your shroud t' t' appropriate length. Begad! I will point out here that it is best t' count how many you will need and nay assume. Ya scallywag! Aye aye! I made t' mistake o' assumin' and learned t' hard way that nay all o' t' Thermal Rider chutes are hexagonal. Blimey! Aye aye! Almost all o' them are but t' 24 incher I received is octagonal. Avast, me proud beauty! That meant that I wound up short one shroud line.

After t' shrouds are cut, set them aside for a moment and apply t' reinforcement disks t' t' corners. Well, matey, blow me down! T' central hole o' t' disk should be approximately concentric with t' hole provided in t' chute itself. Avast, me proud beauty! Avast, me hearties, me proud beauty! Press t' disks on firmly t' make sure they adhere well.

Now t' shrouds are revisited as they are tied t' t' corners o' t' chute. Avast, me proud beauty! Avast! Blimey! I used bowlines t' do this but thar are undoubtedly other ways as well t' tie them on. You do nay want t' loop t' be too big and neither do you want it t' slip and close in upon t' corners.

That does it. Blimey! Blimey! All that is left is t' install it in your rocket usin' your method o' choice.

Flight:
On me first opportunity t' log some flights after receivin' t' chutes, me hearties, I made sure that I had packed t' 6" in t' Vulcan. Blimey! Blimey! After t' rocket reached apogee, shiver me timbers, I had t' novel experience o' seein' a parachute deploy and t' whole assembly fall gently t' earth. I probably could have gotten an 8" in thar but 6" was all that was needed.

T' 12" chute I entrusted t' an entirely new rocket. Avast! It went into a FlisKits Stingray. Well, blow me down! Again, me hearties, it did what it be supposed t' without problem and t' rocket was flown twice that day.

I was goin' t' try t' 24 inch chute in a Hawk's Hobby Super Sprite, shiver me timbers, arrr, matey, but I did nay get t' time. I have no doubt though that it would have performed admirably.

Recovery:
PROs: inexpensive (even if you don't get them for free), me hearties, strong and durable, ya bilge rat, wide color assortment, matey, no cutting, arrr, me hearties, high quality.

CONs: you still have t' put it together.

Summary:
These are great chutes available in a wide selection o' sizes and colors. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! They are strong and easy t' put together.

Plastic chutes are still nay a favorite o' mine, arrr, matey, but they do have their place. Ahoy! These are t' finest plastic chutes I have seen.
