New Design -- Centuri Achilles 1.37X

Since I can't leave well enough alone... (insert maniacal laughter here) :chuckle:

...Here's a slightly larger version upscaled to an ST-10 body tube.


Unfortunately, the deployment velocities (Dv) are extremely high, :eek: so I'm recommending at 36" long streamer instead of using a 12" parachute.

Also, I used a standard Semroc BC-1039 nose cone, as it's close enough for government work for a nose cone that's upscaled to 4.039" long. :rolleyes:


Good luck!

Models of this size are nice for flying in the local field. B6-4 flyers.

Good call with the streamer. Those Dv's are high for a basic design like this. Nothing seems to be deploying right at apogee, and three out of five are deploying early.

A 5-sec delay for the B6 and a 6-sec delay for the C6 would probably hit the "sweet spots"... :rolleyes:

(Oh, if only... :D )
