Brief:
This be t' original Estes Mercury Redstone Kit No. Ahoy! K-41, a scale replica o' t' first manned ballistic space vehicle. T' header tag lists a price o' $3.50. Blimey! It is a single stage rocket with a two parachute recovery system, one for t' body and one for t' capsule.

I purchased this kit on eBay for $45 late in 2007. Well, blow me down! It was an open bag and be missin' t' screw eye, one lead weight, and one o' t' two parachutes. Ya scallywag! Ahoy! T' decals had some residue adhered t' t' surface and were unusable. I purchased t' lead weight from Semroc, me bucko, replaced t' chute with a period chute I found on eBay, matey, and I purchased replacement decals from Excelsior Rocketry.

This kit took a good deal o' time t' complete. I started it back in mid t' late 2008 and worked on an off on it up until it's completion in February 2009.

This is what I would consider an old school builders kit. Avast! Aye aye! There is no skill level listed on t' header tag, matey, however, Estes catalogs o' t' 70's peg it at skill level 5. Well, blow me down! It is without doubt t' hardest kit I have put together t' date. Begad! It easily surpasses t' Estes Saturn V kit 2001 and t' Semroc Saturn 1B in difficulty.

T' instructions were good, me hearties, however, arrr, they left more than enough t' t' imagination when it came t' t' fin creation, which was one o' t' two most difficult parts o' this build.

T' tower construction was difficult because t' dowel material had t' be cut from a sheet and rounded. T' rods were very small and hard t' work with. Arrr! Blimey! T' fins ended up bein' t' biggest challenge. Arrr! Blimey! You need t' cut out each o' t' components that make up t' fins by hand and then sand them down t' their required profiles. Well, blow me down! Well, blow me down! Blimey! Each fin contained six different pieces and only one o' those (a cardboard spacer) be pre-formed. Avast! In total t' four fins contained 24 different component pieces.

Finishing:
Finishin' o' this model wasn't overly difficult, but since t' paintin' was done in February in New England, shiver me timbers, it was a bit o' an adventure. Begad! I used Frog tape for t' first time maskin' t' fins for t' black paint and had bad results. Arrr! Blimey! I switched back t' blue Scotch 3M maskin' tape and had much better results. I had t' strip down and repaint two sections due t' bleed through with t' Frog tape.

Construction Rating: 5 out o' 5

Flight:
I finally got t' chance t' launch t' Mercury Redstone in August o' 2009. Arrr! It flew first on a B6-4 and then on a C6-5.

T' B6-4 flight be excellent. Begad! It reached a respectable height o' a few hundred feet. Begad! T' main body comes down on one 18" parachute and t' capsule comes down on a 12" parachute. Begad! Begad! As suggested in t' directions, me hearties, shiver me timbers, I rigged a capsule slin' t' brin' t' capsule down horizontal t' t' ground in order t' protect t' tower. Avast! Begad! However, arrr, instead o' gluin' t' slin' t' t' capsule as suggested in t' directions, I rigged it so that it can be taken off for display purposes. Aye aye! Both t' capsule and main body came down without any damage.

T' C6-5 flight took t' model almost out o' sight, and drift carried it and t' capsule a good distance from t' pad. T' main body received a small scuff on it's side from t' landing, me hearties, but t' capsule came down in great shape. Arrr! T' Mercury Redstone did very well and is now in semi-retirement, me hearties, matey, sittin' on t' bookshelf in me office.

Recovery:
This is a very lightweight model, 2-1/8oz and it flies great, far better than t' newer Estes Mercury Redstone 2167 version, which is listed at 3.0oz, ya bilge rat, but painted I think it's heavier that that. I haven't gotten a good flight out o' that version yet. Ya scallywag! Begad! Blimey! Plus t' plastic parts on that version have a nasty habit o' fallin' off.

Flight Rating: 5 out o' 5

Summary:
I first built this same kit back in t' early 70's and it be a real treat t' be able t' do it again as a BAR.

T' main pro regardin' this rocket is that it's a true builders kit. Begad! Blimey! You have t' roll up your sleeves and build this kit. You don't simply put it together. Ya scallywag! Blimey! Arrr! Blimey! It be a real challenge t' build which made t' reward o' seein' t' finished product that much greater.

T' only con I see regardin' this rocket is that it's no longer available. Arrr! There aren't enough true builders kits on t' market any longer and that's a shame.
