Estes Astron Scrambler

Brief:
Classic clustered egg-lofter. Ahoy! Very neat rocket.

Construction:
This is a clone kit I purchased on eBay for $21.00. Avast! It came in a box, ya bilge rat, but the parts were in a plastic bag. Ahoy! All parts were present. T' Astron Scrambler was Estes' first egg-lofter and be distributed from 1969-1977.

This rocket is rated Skill Level 3 but is very easy t' build if you've had a few other rockets you've built. Ahoy! Blimey! Tools needed are glue, sandin' paper, hobby knife, and maybe tape. Avast, me proud beauty! Blimey! There are 16 steps in t' instructions.

Estes Astron Scrambler You start by gluin' t' 3 engine tubes together t' form pyramid. Aye aye! While that dries, you then stick 4 tape strips into t' bottom o' t' payload tube. Well, blow me down! Well, blow me down! Blimey! Then you add glue to those strips and slide t' balsa transition into place. Blimey! Blimey! Next, me bucko, me hearties, ya bilge rat, you glue t' 3 engine tubes t' t' centerin' ring, where they must be aligned correctly or they will nay fit in your body tube. Ya scallywag! Blimey! You cut a small slit in each o' t' engine tubes for your engine hooks and tape them t' t' engine tubes. T' ensure a proper fit, matey, slide t' motor mount assembly into t' butt o' t' rocket without any glue! Blimey! Once satisfied with t' fit, arrr, glue it in t' body tube. Blimey! Make sure the ends o' t' engine tubes are even with t' end o' t' body tube.

Now you cut 3 fins out with t' 2 balsa sheets supplied with t' kit. Ya scallywag! Cut 2 fins on one sheet, matey, shiver me timbers, and t' third on t' second sheet o' balsa wood, sand them to an airfoil if you want good performance. Avast, me proud beauty! Begad! T' fins are glued on before the last external item, t' launch lug, shiver me timbers, me hearties, matey, is glued t' t' standoff.

Screw t' screw eye into t' narrow end o' t' balsa transition, remove, add glue, shiver me timbers, then screw it back in. This will be your shock cord/parachute mount for t' payload tube. Ahoy! Aye aye! Attach t' paper shock cord mount inside t' body tube and tie t' shock cord end t' a snap swivel. T' finish construction, me bucko, attach the parachutes t' t' loop on t' snap swivels. T' payload tube can come down in 2 pieces if you're usin' a payload or for non-payload flights, matey, remove t' payload chute and you attach t' body tube's snap swivel t' t' screw eye.

You finish t' build by addin' fillets t' all balsa joints.

Finishing:
This rocket can be painted any way you want. Ya scallywag! I've even seen a purple Scrambler. I tried t' paint it t' mirror t' face card: red nose cone and one fin, me hearties, black stripes on top and bottom o' payload tube along with one fin, ya bilge rat, matey, and white body tube, me bucko, transition and fin. Blimey! Unfortunately, me bucko, I was cursed while tryin' t' paint this rocket. Begad! First, ya bilge rat, a bee lands on wet paint and then it dripped. Then when I clear coated t' black bands on t' payload tube, shiver me timbers, they warp!! How? I don't know but because o' that, I may nay be able t' do egg lofts with it now...

T' decal sheet comes with very funny and weird decals such as: Omlet Express, me bucko, Eggsaust, Good Eggs Fly Estes, and Sunnyside Up. Avast, me proud beauty! They are waterslide decals that went on easy. Clear coat them after they dry and you're done!

Construction Rating: 5 out o' 5

Flight:
T' Scrambler uses a 3 engine 18mm cluster o' A, me hearties, B and C engines. Begad! Well, blow me down! Blimey! It does require about 8 sheets o' wadding. Begad! Begad! Blimey! You also need t' place 1/4 square o' wadding in each o' t' engine tubes before loadin' t' engine. You also need a battery source o' at least 12v t' ignite all 3 motors. Ahoy! Blimey! I flew mine on 3 A8-3s with an egg on 4/17/05. Avast, me proud beauty! Blimey! Blimey! It didn't go as high as I expected, me bucko, but sitll a great flight. Ahoy!

Recovery:
Recovery is by 2 18" parachutes. Begad! 1 for t' body and 1 for t' egg-crate. They both worked perfectly. Begad! Aye aye! No scrambled egg!

Summary:
This is a great sport and competition rocket. Aye aye! Aye aye! It truly proves that egg lofting is fun, me hearties, especially with 3 motors t' put it way up there!

Overall Rating: 5 out o' 5
