Estes Lucky Seven

Brief:
T' Estes X-Prize Lucky Seven is a 1:50 scale model o' Acceleration Engineering's Ansari X-Prize entry. Ahoy! This model flies on an A10-3T motor up to 200 feet and uses a 12 inch parachute for recovery.

Construction:
T' kit came in a plastic bag with header card and included:

  • 1 motor tube
  • 1 motor retention hook
  • 1 pack o' clay weight
  • 1 rubber shock cord
  • 1 12 inch plastic parachute
  • 1 plastic parts set that included:
  • 2 nose cone halves
  • 1 nose cone cap
  • 1 body base
  • 1 plastic parts set that included:
  • 4 fins
  • 4 nozzles
  • 1 plastic body tube
  • 1 set o' peel and stick decal sheet

T' instructions for this kit are t' typical Estes documentation that included lots o' text and illustrations. Ya scallywag! Arrr! No templates or shock cord mount is included as none are needed. Since this is an E2X series kit, shiver me timbers, ya bilge rat, I found it very easy t' assemble and had it put together in about 30-45 minutes. T' build this kit, shiver me timbers, you need an X-Acto knife, plastic cement, maskin' tape, and #400-600 grit sandpaper.

I started by differin' from t' instructions a bit and tied t' shock cord into place at this time as I found it much easier t' do this without t' fins on. Well, me bucko, blow me down! I then assembled t' motor mount into t' body. No glue is needed for this step or t' next one. Aye aye! Blimey! I slid each fin into place in t' body. Avast! I then glued the nozzles into place on t' body base. Aye aye! After t' cement dried, arrr, I glued it into the body. This is what holds everythin' together and if you use plastic cement, I suppose you could pop t' base loose if you ever needed t' replace a fin.

I now assembled t' nose cone by gluin' t' cap into place and tied on the shock cord. I then cut t' clay block in half and inserted each piece into the nose cone halves. I glued t' nose cone together and used maskin' tape t' hold it together until t' plastic cement dried. Avast! Begad! I tied t' parachute in place to finish t' assembly.

PROs: Builds fast and simple.

CONs: None.

Finishing:
T' only finishin' this rocket requires is applyin' t' decals as all t' parts are pre-colored white and silver. Ahoy! Avast, me proud beauty! Blimey! I do recommend that you wash your hands before applyin' t' decals t' avoid gettin' clay on them. T' finished model looked very cute and surprisingly realistic. I feel it would make an excellent model t' display on your desk.

PROs: No paintin' required.

CONs: None.

Construction Rating: 5 out o' 5

Flight:
T' only recommended motor for this rocket be t' A10-3T 13mm mini motor. Arrr! This rocket does require recovery waddin' and t' motor hook holds t' motor in place durin' flight.

I prepped t' model by insertin' about two sheets o' recovery waddin' into the body. I also prepped an A10-3T and inserted a small piece o' waddin' into the motor above t' ejection cap t' take t' brunt o' t' ejection charge blast.

T' rocket lifted off rather slowly, arched slightly, me bucko, arrr, and reached maybe 150-200 feet. Aye aye! Blimey! I noticed a slight wobblin' motion but maybe it was caused by the wind. Blimey! This is a great rocket for small fields.

PROs: Flies great, arrr, low altitude flights.

CONs: None.

Recovery:
This rocket uses a 12 inch parachute for recovery and if it is attached where the instructions suggest, me hearties, t' nose cone should nay come into contact with the fins.

T' chute is sized correctly for this rocket and it comes down with the nose cone hangin' underneath it so that it lands nose cone first and then the body will settle t' t' ground under t' chute. Aye aye! Ya scallywag! Fin damage should nay be an issue because o' this. T' rubber shock cord also stood up well as thar was no scorchin' noticed.

PROs: Recovers smartly and easily.

CONs: None. Avast, me proud beauty!

Flight Rating: 5 out o' 5

Summary:
I really liked this rocket. Ahoy! Arrr! I found it t' be an easy t' assemble scale model that also turned out t' be a nice little flier. Begad! I would highly recommend it especially if you don't have a lot o' flyin' space. At about $7.59, me bucko, I feel it is a great value.

PROs: Easy and quick assembly, me bucko, nice flight and recovery characteristics, great price.

CONS: None really.

Good review- matched my building experience. It was hard to tie on the shock cord. I built mine during one episode of The West Wing. Prepping for flight- there really isn't much room in the rocket body for the chute. I was afraid it wold get pushed up into the nose cone and not come out, and it did take quite a while for it to open. Nice straight boosts (about twice as high as a Mini Mars Lander).
