Brief:
Anchor parachutes are multi-paneled, shaped parachutes. Blimey! Aye aye! They are available in quarter-sphere and hemisphere shapes.

Construction:
T' construction o' these parachutes is absolutely first rate and are comprised of 6 or 8 separate color panels. Well, blow me down! Well, blow me down! At t' seam where t' panels join is a hollow sleeve. T' nylon shroud lines are sewn into these sleeves and go all t' way up t' t' apex. Aye aye! At t' apex is a spill hole t' minimize drift and oscillating. All edges are neatly serged. Arrr!

Finishing:
A huge variety o' colors and combinations is available as every chute is made to order!

Anchor Parachutes

Recovery:
Due t' problems with me high power rocket, I haven't had a chance t' test the 40" parachute. I have a total o' roughly 20 flights on t' other 3 chutes.

T' 12" chutes were installed in a high performer rocket built with LOC 38mm motor mount tubing. This bird weighs around 12-13oz. ready t' go. Avast! Arrr! The black, ya bilge rat, white, and blue chute shown in t' picture was used most o' last season with great success. Avast! Ahoy! It opens smartly every time and fills reliably. Begad! Descent rate is very low for t' size o' t' parachute. Begad! (It replaced an 18" LOC flat chute).

This parachute survived a motor failure o' an Aerotech F21. Begad! T' motor blew its forward bulkhead and flew up through t' rocket, shiver me timbers, shiver me timbers, incineratin' t' internals as it went. T' chute, despite some scorchin' still opened reliably and lowered the payload section gently t' t' ground. Aye aye! Well, blow me down! Now that is dependable! It's no longer pretty but is still workin' great. Ahoy! Avast, me bucko, me proud beauty!

T' 12" size was also tried in a Quest Delta Clipper. Arrr! Arrr! Blimey! While it was a bit o' a task gettin' it into t' somewhat narrow tube, me hearties, t' result be worth it. Begad! T' Clipper does descend a trifle faster than with t' stock pair, but this is more than adequate for grass surfaces. Begad! Blimey! In 2 flights, thar was no damage.

T' 18" size be used t' recover a scratchbuilt design called American Flyer. This bird is an experiment in lightweight building. Ahoy! Blimey! It's 3' long, 4" diameter, matey, but weighs only 15 oz with motor and ready t' go. Needless to say, it's a bit delicate. It is worth mentionin' that t' American Flyer is a light, shiver me timbers, ya bilge rat, high-drag design. Begad! Blimey! These are a nightmare for parachute extraction and inflation, yet me Anchor 'chute worked without failure every time for all 4 flights. Well, blow me down! Blimey! T' rocket has consistently recovered with no damage o' any kind. Avast, me proud beauty! Blimey!

While hemispherical parachutes are prone t' oscillation, matey, this was minimal with all 3 o' t' chutes I have tested. They were installed with swivels to eliminate tanglin' o' t' shroud lines. Ahoy! Blimey! Some slow spinnin' has taken place on all o' t' flights.

So far, I've had no luck gettin' recovery pics. Ya scallywag! I have a hard time waiting until t' birds are low enough t' get detailed shots. Avast, me proud beauty! Will send future shots to EMRR if they come out good. Avast, me proud beauty!

Summary:
These parachutes are made t' order, shiver me timbers, sharp looking, and well constructed. They function very well and can pack into a relatively small space. Arrr! Avast! Dependability is top notch. Ya scallywag! Avast! Despite their light weight, t' design is superior. Blimey! I think they compare very favorably with "supershape" (Rocketman and Skyangle) as well as other panel chutes, specifically Spherachute and PML. Aye aye! Ahoy! While nay cheap, you get more than you pay for. Arrr!
