LOC Onyx as a Level 1 rocket ?

Post by Smith Famil » Sun, 06 Jun 1999 04:00:00



Group,

I have an Onyx constructed and ready to paint.  I'd like to certify level 1
in the next month or so to show an ailing Father what an H motor can do.  My
question is would an Onyx make an acceptable machine for this task.
Construction has been yellow glue with epoxy for motor mounts.  I have a
decent homebrewed motor retention system.

Any opinions would be welcomed.

I certified level 1 a couple of weeks ago with this very set-up, and it worked
quite well.  The only modification I made was to put very substantial epoxy
fillets along the fin/tube joints.  Good luck on your cert flight!

> Malcolm,

I would not recommend using your Onyx for your level one cert flight.  But
if you do be very sure of your CP CG relationship.  I have not flown an
Onyx, but I have 15 or 20 LOC kits.  I would recommend a LOC IV on an H128
S, or similar.  I would also recommend buying an extra centering ring, as
this will let you put inside fillets on it.  Some folks even notch one of
the rings to accept the fins.  I don't know how important this is as my
Level 2 rocket was a LOC Iroc and it used small dowels glued to the inside
tabs and this took the rather considerable oomph of a J350.  The Iroc by the
way makes a very good L1 and L2 rocket.  I motor L1 J350 L2.  Good luck and
remember that none of the guys here  know everything :-)

                                                Cheers,

A stock Onyx might be used for cert if you carefully get your cp/cg
right. You'll likely need to put some noseweight if you want to fly it
on say, an H180 for your cert 1.  Personally, if I have to chose
between adding noseweight or stretching (ie: lengthening) the rocket,
I would chose the latter.  In fact, I did.  I certified L1 in '97 on a
streched onyx (45 inches long) and it flew great. :)  At that point
though, it was very similar to a LOC forte' without the fin tabs.

I have flown several stock Onyx kits on all of the 29/180 reloads. My suggestion: Use
the H238-M and impress yourself.

Hmmm...That's a toughie! The Onyx is a neat little rocket. I lost mine on a F50
in a small field. First flight, IIRC. An H128 is the shortest H 29mm available
(AT reloadables anyway). Make sure the Onyx is stable and launch in a big
field. Don't blink at liftoff! Good Luck!

Good LORD Ken.  Yes this would certainly get off the pad smartly.  My LOC
Graduator sprang off the pad with an H238 and it's a good 4 oz heavier
than a stock Graduator!

An ONYX?  Bring one of those to Hellfire 5, I wanna see it.

An Onyx on a G35 is a fantastic flight.  Go for the long burn.  Do an Onyx
on an H97.
