Brief:
This is a 5x upscale o' t' Estes Astron Spaceman. Ahoy! You can read that review here. Throughout, me hearties, I will reference WE because this was a project that be done my myself, me bucko, t' kids and their grandfather.

Construction:
These are t' parts we used:

• 1/4" ply
• 7.5"x 13.75" outer tube
• 4" x 13.75 inner tube
• 2-1/2" launch lugs
• 4-8/32 t-nuts (for motor retention)
• 2-36" parachutes
• 1-4"x2" coupler
• 1-8" ball (for head)
• Fiberglass cloth
• 2-4" centerin' rings
• 1-1/4"x 8' tubular nylon shockcord
• 1-1/4"x4' tubular nylon shockcord
• 1-29mm tube 9" long
• 2-29mm tubes 7" long

First thin' we had to do be upscale t' fin patterns. Begad! Avast! We did this on t' PC. Avast, me proud beauty! Blimey! After we got the patterns upscaled we decided t' make a few changes t' them. Begad! Avast! (See t' picture). What we did was t' make t' legs as one piece instead o' two. Begad! We did this so the leg/arm assembly would be stronger. Aye aye! If you look at t' picture you can see. We also added tabs for TTW fin attachment in t' t' motor tube. Blimey! Then small tabs on t' leg/arm assembly t' t' inner fin set for added strength. Well, blow me down! Notice the picture o' leg/arm assembly once they where cut out (below). Avast! Here (picture below) you can get a better idea o' t' tabs I added t' get everythin' to interlock for strength.

After everythin' was cut out we started by buildin' t' inside tube and fin assembly. At this point we only had one (1) 29mm motor tube planned. I will explain later why t' other two (2) motor tubes came into play turnin' this rocket into a cluster. Begad! Here is a picture (above) o' t' inside tube with the fins attached and launch lugs on. Aye aye! Begad! Again you will notice t' notches on the inside fins these are t' interlock t' leg/arm assembly.

For t' leg arm assembly we used 1/4" birch plywood because we where tryin' t' keep t' weight under 4lbs. After we had t' leg/arm assemblies cut out we added two coats o' fiberglass cloth t' both sides for strength. Ya scallywag! Doing this really stiffened up t' leg/arm assembly. Begad! After t' leg/arm assembly was set up, me hearties, me bucko, we had t' cut four (4) holes into t' outer 7.5" tube for the leg/arm assembly t' fit into t' inner fin assembly. Avast, me proud beauty! Arrr! Once we had t' holes cut for t' leg/arm assembly we put t' inner tube into t' outer tube than put the leg/arm assembly into t' outer tube. Where we made t' interlock for the leg/arm's t' t' inside fins we used fiberglass cloth and epoxy t' cover this joint.

Next came makin' t' base and addin' t' supports. Begad! T' base be easy as it is 4 pieces o' 1/4"x 13.75" long makin' it into a square. After the base be done we supported t' main body center in t' base usin' epoxy to secure t' legs t' t' base. Avast! After this set up we added t' outer two base supports.

At this point we felt we where doin' good, t' entire body with parachute and shock cord only weighed 3lbs a full pound under t' target weight.

However . Avast! Begad! . Ya scallywag! Avast! .

We still had t' make t' head and get everythin' balanced right. Aye aye! Blimey! T' head is a 8" styrofoam ball coated with fiberglass resin for added strength. Once t' ball was coated we epoxied t' 4" coupler t' t' ball. We now put the head on t' t' body t' check where are CG was and it was too far back! Blimey! We needed t' CG t' balance at t' elbows for t' rocket t' be stable. Aye aye! Blimey! So we made a hole into t' ball where t' coupler attached and started addin' lead shot until t' rocket balanced at t' elbows. Begad! Blimey! We now re-weighed t' complete rocket and were surprised t' find out we added over 2lbs o' shot in t' head t' get it balanced. So much for t' target weight!

We felt this was no good but how could we still fly this with motor options. Aye aye! So we decided t' add t' other two (2) 29mm motor tubes turnin' this into a cluster and givin' us more options for flight. We did this by drilling out t' bottom centerin' rin' only and makin' these tubes only 7" long to take up t' a 29/180 casing.

Flight:
T' plan when we started this was t' fly it on a H128 or a H180, ya bilge rat, but after comin' in at 5.5 lbs finished t' H128 was out.

But with t' cluster setup now it can be flown on a variety o' combinations such as:

• 3-G80's
• 1 H128 & 2 G80's
• H180
• or even possible
• 1-H180 & 2 H128
• You get t' idea

For t' shock cords we have a 8' 1/4" tubular nylon shockcord on the body and a 4' shockcord on t' head. Ahoy! We decided t' brin' t' rocket down in two pieces.

There was no need for waddin' since we used a Keelhaul®©™® 'chute protector.

For t' first and only flight so far we used a H180 with a short delay (6sec). Avast, me proud beauty! Blimey! We felt this would be too long o' delay and it was. Avast, me proud beauty! On t' H180 the rocket took off straight up t' about 500-600' then our hearts began t' scuttle the rocket just kept comin' down until about 200-250' before t' ejection charge went off. However once it did both chutes and pieces came down unharmed though a little fast. Begad! Next flight we plan on goin' t' twin 48" chutes

Summary:
Over all t' kids, arrr, their grandfather and I had a lot o' fun plannin' and buildin' this.

T' kids already want t' build another upscale o' t' Astron Spaceman but goin' t' an 8x upscale t' get a life size man ;-)
