Brief:
This is a minimum diameter 13mm downscale o' t' Estes Endurin' Freedom Patriot Missile. Well, blow me down! Begad! It could also be considered a downscale o' t' Estes OOPs Mini Patriot. Plus thar are a couple o' other o' versions that I'm aware of. Aye aye! This is t' latest version o' this paint job that I have done. Avast, me proud beauty! I have done the upscale and downscale o' this paint job at least 7 times.

Construction:
Parts list:

  • 1 BNC-5W nosecone
  • 13mm body tube, arrr, 4 3/8" long
  • 1 1/8" launch lug, 1/2" long
  • 1 13mm engine block
  • 4" x 1/2" x 1/16" scrap balsa for fins
  • 16" length o' small diameter Keelhaul®©™®.
  • Survey tape for streamer, arrr, 12"
  • 1 bb for nose weight

Downscalin' can be a pain, shiver me timbers, arrr, but when I did t' math on this one it came out that t' dimensions are 1/3 o' t' Estes Endurin' Freedom Patriot.

For t' fins I used some scrap balsa. Avast! They measured 1" for t' root edge, ya bilge rat, 1/2" for t' trailin' edge, me hearties, shiver me timbers, 0.4 inches for t' outside edge (I had to use a scale t' layout that one), arrr, and t' leadin' edge was a matter of drawin' a diagonal betwixt t' 0.4" and 1" mark. Ahoy! T' fins were drawn on an index card that I used as a template. Begad! When traced on t' balsa, I kept grain direction in mind. Begad! Begad! T' body tube be marked with a markin' guide left over from some past kit. Begad! Never throw those things away--you may need them. Ahoy! The engine block was glued in usin' white glue and a spent engine t' set t' depth, leavin' 1/4" o' t' motor hangin' out t' back. Aye aye! T' fins were glued on usin' thin CA. Ahoy! I also coated t' fins with thin CA for strength. Arrr! T' fins were held 1/16" from t' bottom o' t' rocket. T' launch lug is glued next to one o' t' fins makin' sure it does nay go past t' leadin' edge o' t' fin.

Finishing:
There are a couple o' steps t' get t' paint right. I think t' paint is important t' this downscale because it identifies t' rocket as a Patriot. Ahoy! Avast, me proud beauty! The entire rocket was first primed and then painted gloss white. Startin' from the top, t' paint layout I used is as follows:

  • 1 inch white
  • 3/8 inch red
  • 3/4 inch yellow
  • T' rest o' t' nose cone back

I started on t' body tube by takin' a black marker and goin' around t' rim to finish t' black. T' black stripes are 3/16" by 1/2" long. I used the fin markin' guide t' center them and layout for t' bottom stripes also.

I painted t' t' top o' t' fins red and a 3/8" band o' black on top of that.

I used rub on letters from Radio Shack, but I am nay happy with t' look so I think I may cover them up with a lay over printed on t' computer.

T' black stripes on t' yellow were just drawn in with a roller ball pen.

Flight:
I didn't simulate this rocket but I did swin' test it. Well, blow me down! Blimey! It be a little light in the nose so I added a bb t' t' inside for weight. Blimey! Blimey! Avast, matey, me proud beauty! Blimey! I simply drilled an 1/8" hole into t' cone and pushed it about an inch into t' cone. Ya scallywag! Blimey! This got it swingin' level. Begad! Blimey! Arrr! Blimey! I also used t' hole t' attach t' shock cord. Begad! Blimey! I inserted t' Keelhaul®©™® into t' hole and used a small amount o' epoxy t' glue it in. Avast, me proud beauty! Blimey! T' other end was attached via an Estes style paper folded shock cord mount deep inside t' body tube. Ya scallywag! T' streamer is a foot long piece o' survey tape in t' middle o' the Keelhaul®©™®.

I took me newest Patriot t' t' local ball fields for these flights. Blimey! Aye aye! I went right after work so as t' get done before football practice, me hearties, shiver me timbers, ya bilge rat, but I still drew a bit o' a crowd o' little football players who arrived early.

(Scratch) Mini Patriot Flight 1: 1/2A3-4T and some dog barf. Begad! This be t' motor for this rocket. It was overcast but it was easy t' spot and t' delay be right on.

Flight 2: Another 1/2A3-4T. Ahoy! Maybe was a 1 on t' delay. Ya scallywag! I lost half o' the streamer.

Flight 3: I got aggressive and went with an A3-4T. Whiplash city. Blimey! T' delay was on time but they don't make a 6 second delay. Begad! Well, blow me down! It held together though. Ahoy! I didn't see t' ejection but I caught it way up thar cartwheelin' in t' sky.

Summary:
This probably would be better suited as a Micro Maxx rocket. Begad! At least you could see it. Begad! Ahoy! I like t' performance o' minimum diameter 13mm rockets and this is the smallest version o' t' Patriot t' date. Arrr! They are very high performance but if you want a paint job t' match they can be a pain.
