Simple answer: The EZI is one of the all-time favorite rockets for
HPR certification. It flies well on G80-4, almost all H RMR motors, and
some I motors, when built totally stock. It was not originally intended
or
designed for high thrust I motors (like an I357, I284, etc). And it most
definitely was not originally intended for J motors. However, it has
been
successfully flown with all of these (although typically 'hardened' in
some manner for the bick-kick I and J motors).

LOC quality has been pretty consistent (good to excellent) for the 5
years
I've been in HPR.

My only complaint about the kit is the insistance on just TTW fin tabs
instead of TTW to the motor mount fin attachment.

I certified TRA lvl 1 this past May flying a EZI on an H123-M reload.
A wonderful rocket that I'll truly miss.  (It was lost to the rocket
gods thanks to the evil imps of the power lines.)

Here's the pertinent excerpt from my launch report...

LOC/Precision EZI-65:  H123-M
SUCCESSFUL Level 1 certification flight!
I kept it nice, safe, and simple.  WRASP had predicted all of 1300 ft.
With the wind, I figure that I might have gotten about 1000 ft (at
most.)  Launch and flight were very nice.  That large 35" chute
carried it a good ways downrange but landed it nice and gentle (albeit
in a bare field, just to get it dirty.)  No damage other than one
small ding in the paint on one fin.

I made a few modifications to this bird.  First, I added three
(reinforced) screws to secure the nose cone to the payload section.
Second, I revised the assembly process so that I could put substantial
epoxy fillets on the fin tabs inside the main airframe.  Third, I put
an eyebolt through a reinforced section of the upper centering ring
and ran 1/16" steel cable up to a loop just inside the upper end of
the main airframe.  (This instead of the LOC "glob o' epoxy" style
shock cord mount.)  A slightly modified LOC 54 to 38 adapter was used
for the motor.  The motor was secured into the rocket using an
aluminum retaining plate bolted to two 8-32 blind nuts set into the
rear centering ring.  Yes, it did turn out heavy - 44 oz. including
the motor adapter and aluminum retaining hardware.

I also launched it the next month on an I161.

Hope you find the info useful,
Alan

I certified on the EZI-65, with an H220 Silver Streak (anybody remember
those?). It's a fine rocket.

The EZI-65 small enough for an ecomomical (but full) G-motor, a blast
with any H-motor, extreme cool on most I-motors (except the I65 because
I lost it at Culpepper a few years ago, it's a personal thing). Even
seen them do really well on J-motors.

Go for it. You'll have a great time.

Have fun,

I'm puzzled, mine fin-tabs went all the way to the motor-tube.

Hmmmmmmmmm

Have fun,

  I've still got a few of these left but am wondering if Vern will be
successfull in having them outlawed!
  My wife certified successfully with an EZI using an I284 at LDRS96
in Orangeburg. Approached 4K in altitude and landed in the trees about
30ft up. Special thanks to the guy with the telescoping pole!
  The EZI has a 54mm motor mount which makes it ideal for a wide
variety of motors. If you dig cardboard it's a great kit.
