PartsI 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. Like the Magnum Hornet, this kit flies on D motors but includes an adapter for A-C powered flights.

Assembly was straightforward with the easy to understand instruction sheet.

For the first flight on a windy day, I tentatively installed an A8-3 motor. I had my doubts that this almost 2-ft tall bird would fly on an A. Actually, it wasn't bad. It got to about 100 feet, almost as high as its smaller brother. But, the chute didn't come out. It came in flat, but broke a fin away from the body tube. An easy fix and it should be back in the air.

Next time it will fly on a B6-4 or larger. I'm thinking the A8-3 just doesn't have enough juice to kick out the chute unless the nose is about to fall off by itself.

This is another pretty easy kit, and I can't wait to see it fly on a D motor...

    Brief: Simple 4FNC rocket with parachute recovery. Chan's review is complete and my experience was pretty much the same, so I'll just try to add a few comments and photos. For instance, the marketing people at Damon/Estes borrowed the Magnum moniker because it equates with "over powered". That's true with this kit. A D12-7 will easily send it out of sight. Con ...

    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 ...
