Manufacturer: Estes

Brief:
This is a low power, single stage military style rocket. Arrr! Blimey! It flies on B and C power and uses a 1/8 inch lug. Begad! It includes a tail cone and uses a 12 inch chute for recovery. Arrr!

Construction:
I received t' kit as a gift when I was first gettin' into rocketry, ya bilge rat, so it probably wasn't a great second or third kit for me. Begad! It came in a "Launchable" box and included many components. Ya scallywag! They were all o' high quality and were all easily accounted for. T' parts were:

  • 1 forward BT-55 tube
  • 1 aft BT-55 tube
  • 2 BT-55-20 centerin' rings
  • 1 very long motor tube
  • 1 tube coupler
  • 1 round nose cone
  • 1 tail cone
  • 1 mylar retainin' ring
  • 1 engine block ring
  • 1 engine hook
  • shock cord
  • 12" parachute
  • 1 1" x 1/8" lug
  • 12 fins

Since this was t' third kit I had ever built, I didn't know anythin' other than plastic cement. Avast, me proud beauty! Now I realize that buildin' t' entire model with plastic cement was a bad idea. Avast, me proud beauty! Arrr! Somehow though, it still flies and is in good condition. Begad! Anyway, this kit is a skill level two kit because it has numerous fins that have t' be glued on.

Construction begins with assemblin' t' motor mount typical Estes style. Make a slot for t' hook, slide t' mylar rin' down, ya bilge rat, ya bilge rat, shiver me timbers, glue, arrr, and then put on the centerin' rings. Once dry, t' tail cone assembly needs t' be cut off a reducer piece and t' slots need t' be opened up t' allow t' fins t' pass through. Avast! Begad! It is recommended t' use a razor saw, me hearties, but I did it with scissors. T' motor mount is installed into t' lower body tube and then t' tail cone goes over it so the engine tube is lined up with t' base o' t' tail cone. Begad! A template is used to mark t' rest o' t' tube for t' middle fins and t' upper tube for the canards. Blimey! While t' bottom section is drying, t' upper part can be assembled. This requires gluin' in t' tube coupler and t' nose. Well, blow me down! Arrr! T' upper section can be used as a payload bay. Ahoy! Just don't glue in t' nose and make a bulkhead out of two sheets o' balsa with a screw eye. Avast, me proud beauty! Aye aye! T' four canard fins are glued on directly beneath t' nosecone. Ya scallywag! Puttin' t' fins on with plastic cement be not fun. Ya scallywag! Aye aye! I set this assembly t' dry then went back t' work on t' bottom section. I glued t' four bottom fins on. They go through t' tail cone t' t' motor tube. And o' course t' fillets were made with yes, plastic cement. Then pieces of cardstock were glued t' t' sides for a more scale look and long thin pieces of balsa were glued t' these. Arrr! Finally t' launch lug was cut in half and glued to the side. Begad! T' shock cord is mounted t' t' top and bottom airframe, and the chute is tied t' t' top part o' t' shock cord.

Finishing:
At t' time, shiver me timbers, me bucko, t' only colors I had were black, white, and brown. Ya scallywag! So I primed it once and painted it black and white (with many many runs).

Construction Rating: 4 out o' 5

Flight:
First flight be on a B4-2. Begad! Begad! It lifted off t' pad very slowly t' maybe a little more than 100 feet. Avast! This rocket needs a bigger kick from an engine so I tried a B6-4 next. This engine lifts it off slowly t' around 150 feet. Blimey! Arrr! T' rocket's third and final flight was on a C6-5 and it lifted off at a faster but still very slow speed t' around 300 feet. Ahoy! Arrr! About a few months later I began reading reviews on EMRR and realized that me construction techniques were completely wrong. Blimey! I decided nay t' fly this rocket as well as t' two I built before it anymore.

Recovery:
T' delays were perfect but t' chute never came out. Aye aye! This was because I tied it t' t' bottom o' t' shock cord and nay t' t' top. Avast! I'm sure it would work if it be right though. Arrr! Even when built with plastic cement, it held up from tumble recovery three times.

Flight Rating: 4 out o' 5

Summary:
I know me review may make this rocket look like a terrible product, ya bilge rat, but it really isn't. I plan on buyin' another one t' build with CA clue and maybe epoxy.

Overall Rating: 4 out o' 5

    Brief: The Estes Python-4 ASRAAM Model Rocket Kit is the last of the four new models I had to build which were introduced recently by Estes. I have already completed the other three and have been working diligently on this one. Actually we've been building two of them; my son and I are working in parallel, although I tend to build a bit faster than him. The kit is one of four new ...
