LOC Magnum vs LOC Magnum - 3

Post by Bob Crowle » Wed, 11 Mar 1998 04:00:00



I see that a couple of LOC kits have a -3 version (ie:
Magnum/Magnum-3, and Bruiser EXP, Bruiser EXP-3.) Can anyone
tell me what is the difference between the regular and the
-3 version? Thanks!

Shure can Bob, I have started filling my Bruiser Exp 3.

The (3) tells that the rocket will have a 3" motor mount, instead
of the 54mm motor mount.  I can speak for the Exp 3,
The fins from it (G10) come through the body and mount
to a "fin can" the "fin can" is closed off by two centering
rings, followed by a third and the forward of the motor
tube (making 3 centering rings)

The reason for the 3" motor tubes, Kosdon has his
3" motor out, and Aerotech has one due out this
summer.  Rummor is they will be L's and M's
but cheaper than the 98mm 's

I modified my Bruiser Exp 3 to also use 4 38mm
motors, and covered the motor tube, and body in
4 oz kevlar.  Enforced the fins with carbon.  Plan
on using an M in it.

Hope this helped.

That's because the 3" mount Bruiser is a Bruiser-EXP 3, not a Bruiser 3. The Bruiser EXP is an expanded Bruiser with a
payload section. The 'regular' EXP has a 54 plus 2 38 mm mounts. There is no 'tube in tube' construction. The regular
Bruiser comes with 2 centering rings. The Bruiser EXP comes with 3 (two drilled for all three motor tubes and a forward
centering ring drilled for the 54mm tube only. The Bruiser EXP also comes with 2 chutes (72" and 48" LOC style flat
pannel chutes). The Bruiser comes with a single chute.

The Bruiser EXP 3 is the Bruiser EXP with the 3 mounts replaced with a single 3" mount inside another tube, 5.5" I
believe. The fins are TTW and attach to the 5.5" tube.

There is also a LOC Magnum and Magnum EXP, the EXP is longer and has 3 motor tubes (a 54 and 2 29's I think). The Magnum
EXP 3 takes the EXP and converts is to a single 3" motor mount. No tube-in-tube for this one, though.

Oh, yes. The 3" motor versions of both the Bruiser and Magnum EXP
s are supposed to come with G10 fins instead of plywood.
