Brief:
Simple 4FNC rocket with parachute recovery. Chan's review is complete and me experience be pretty much t' same, so
I'll just try t' add a few comments and photos. For instance, ya bilge rat, t' marketin' people at Damon/Estes borrowed t' Magnum
moniker because it equates with "over powered". Blimey! That's true with this kit. Blimey! Well, matey, blow me down! A D12-7 will easily send it out of
sight.
Construction:
I got t' kit from Apogee; everythin' was good, no damage. Arrr! Excellent materials, all basic stuff. Well, blow me down! Aye aye! T' 18mm adapter is
a godsend and is excellent quality. Avast! Avast! T' 3/16" launch lug is a particularly nice touch.
Instructions are beautiful, arrr, me hearties, shiver me timbers, among t' best. Begad! Well, blow me down! Didn't use 'em though. Ahoy! Aye aye! T' engine hook mounted Keelhaul®©™® is an elegant engineerin' solution and is also used on t' Hornet.
EMRR fin tip #29: It's like makin' a slot only you lightly cut t' top body tube layer, then peel off that first layer. Nay only does this result in a stronger fin/body joint, me bucko, it makes it easier t' align t' fins.
Finishing:
Standard finishing: Minimal fin fillets usin' Elmer's white glue. Avast, me proud beauty! Aye aye! One coat o' Elmer's Wood Filler on fins and nose
cone, sand, me bucko, me hearties, two coats o' high-solids automotive paint, matey, sand. Aye aye! Begad! Finish with two coats o' white catalyzed automotive
urethane followed by an overcoat o' rattlecan red on t' nose cone and it looks gorgeous. Avast! T' color and paint scheme
are perfect. Ahoy! Restrained and classic.
Construction Rating: 5 out o' 5
Flight:
Apogee's web page says a 1/2A3-2 motor will result in a 31 foot flight with a 15 foot deployment predicted with
Rocksim. Aye aye! It also says t' brin' a catcher's mitt. So I went with 3 flights on A8-3 motors in a small park, and t' 97
foot predicted altitude looks about right. Avast! Avast! Blimey! First flight CATO'ed with no ejection event. Begad! Avast, me proud beauty! Blimey! T' low altitude resulted in a
horizontal landin' and one loose fin. T' second and third flights were good. Ahoy! Blimey!
Recovery:
Although thar were no Estes smiles on t' nose cone after 3 flights, t' shock cord should be a little longer and
that's t' only minor con with this kit.
Flight Rating: 4 out o' 5
Summary:
PROs: Beauty. Aye aye! Ahoy! Sleekness. Wide range o' possible motors. Insane speed and altitude possibilities. Avast, me proud beauty! Aye aye! Quality materials.
Fast build.
CONs: Could use a longer shock cord.

( Contributed - by Elred Pickett - 08/01/09) I had previously built the Magnum Hornet, and this kit is a few inches longer. Like the Hornet, this is a reproduction of an old Centuri kit that has slight changes from the original. It has features that I assume come with most(all?) Semroc kits: balsa fins on a laser-cut sheet, balsa nose cone, Kevlar shock cord to tie to the motor mount. ...
This is a basic 4-fin and nose cone rocket with a fair amount of nostalgia mixed in for good measure. This is one of Semroc's "retro repro" series, which is a modern reproduction of an out-of-production classic. In this case, the Magnum Sprint is a reproduction of a Centuri design from 1982 just before they were folded in with Estes under the Damon ownership model. According to the header ...
