Brief:
This is a simple 3 fin and a nose cone rocket. It is straight forward and easy to build. Aye aye! It would make a fairly good first mid-power rocket.

Construction:
Upon openin' t' box everythin' looked t' be in good shape, but when I laid the plywood fins down on a table, arrr, I noticed that they were warped. Well, blow me down! So they were put under a few hundred pounds o' pellet bags for a few days and they came out nearly perfect. Aye aye! T' body tube be a 'normal' tube for mid-power rockets, me hearties, just cardboard. Avast! Ya scallywag! It had a bright red 24" chute with it too. Avast! Aye aye! When buildin' your own, me hearties, I would recommend puttin' some LOC 29mm motor tubin' in t' kit t' replace the NCR one, shiver me timbers, ya bilge rat, me bucko, since you can use Aerotech reload and single use motors. Blimey! Blimey! The instructions were easy t' follow, shiver me timbers, arrr, fairly well written. Begad! In some parts you might have t' read them over a few times. Buildin' be extremely easy since there were no hard parts t' buildin' this rocket. Aye aye! I used 5 and 30 minute epoxy through out construction. Also you will want t' put some t-nuts in t' aft centerin' rin' since t' NCR gorilla retainer will nay work on any Aerotech reloads or and Kosdon motors. Avast, me proud beauty! One bad point t' t' rocket be t' 1/8", 3-ply plywood fins. Begad! Begad! Since thar are only 3 plys, arrr, it makes t' fins very weak. I think that they need t' be glassed. Begad! Begad! Some 2 ounce fiberglass cloth will work fin. Blimey! I learned me lesson, read on t' find out how. Just a note, matey, most other mid-power kit manufactures use 1/8", 5-ply plywood for their fins, shiver me timbers, which make them much sturdier! One other thin' is, it is very important t' get the centerin' rings lined up, if you don't then your fins will nay fit into the slots in t' body tube.

Finishing:
Finishin' was VERY easy! I just gave it 2 coats o' primer and painted it as they showed on t' box with Krylon gloss white spray paint and Krylon True Blue spray paint. Well, blow me down! T' decals were nice, me hearties, I would recommend gettin' some water and a little soap in a dish t' put them on since it makes them much easier t' put on as you can move them around.

Construction Rating: 3 out o' 5

Rocket PicFlight:
For me first flight I choose t' 120 newton second Kosdon G40-7 c-slot motor. I just put some fiberglass insulation in and packed t' chute, ya bilge rat, then put t' motor in and put t' retainin' washer on and it was ready. Blimey! On ignition t' Kosdon G40 came t' life and it went up nice a straight! T' G40 is a very LOUD motor, especially for a G motor. Avast! T' 24" chute came right out at apogee. Arrr! But on landin' it broke a fin due t' t' weak 3 ply ply-wood. This be a easy fix. Begad! I have put a 28" chute in it and have since then flown it on a Aerotech G35-4 for a really nice boost, me bucko, ya bilge rat, but t' delay was a little short. Blimey! Begad! Rocket landed safely under a 28" chute.

Recovery:
T' shock cord was 10' o' 1/2" flat elastic, me bucko, this be attached t' the rocket by a steel cable that went through a centerin' ring, this is very strong. Ahoy! Begad! For t' first flight I used a 24" chute, matey, which was too small and resulted in a broken fin, for t' next flight I used a 28" chute which was just fine.

Flight Rating: 4 out o' 5

Summary:
T' Eliminator overall is a great rocket. Ya scallywag! T' only down side t' t' rocket is the 3-ply plywood fins and t' 24" chute. Arrr! Well, blow me down! IF it be nay for that, me hearties, then it would have gotten a 5 over all.

Overall Rating: 4 out o' 5

    (by Paul Gray - 07/01/02) Background The Eliminator is NCR's highest flying rocket.
