I flew mine on a G-64 last weekend - it was great! It was 'almost' out
of sight (or was it??) and ended up landing right near the car. I
think if you move up to H's - you better have a lot of recovery room.
Although I haven't tried it myself (and I'm not sure I want to) I
remember others saying they have flown a Graduator on an H. Some have
said they've done their level 1 certification with it.

I did what seem to be 'standard' mods - the Kaplow clips, and an ORI
type baffle including the extra centering ring (I really like the
baffle - no wadding is nice on a 2.6" rocket). It weighs in at about
17oz (without the motor/casing). Let me know if you need more detail.

Good luck with yours - I'll be curious about how it works,
Jeff

Pal of mine did his Graduator with an h238.  Very cool.  Very highly
reccommended.

Mine went to 6280 on a I211, and 4800 on an I161 at Bend last weekend.

How did you track a Graduator at 6280 and 4800 feet ?   You must be
the champion of Squinters there ;-)  Or maybe you used a pound of
tracking powder? :-)

I would guess that an Adept altimeter was used.  Of course, the real
altitudes are +/- 10%.

It's painted white at the nose, black at the fin can, and transitions
through fluorescent orange, red, green in between.  With the sun at my
back, I can usually track the lower flights.  With the higher ones, I
rely on crowd participation.  It really helps to have Steve "Eagle Eye"
Bayer on the team.  He could probably track an Estes Mosquito second
stage on a FULL "A" motor, boosted on a "Z".

I usually fly out of Steve=92s tower, which yields a really straight
boost.  I also use dual stage recovery.  Between the two, It usually
comes down relatively close to the pad, even in wind.  The engine blows
the rocket in half , I don=92t use a streamer or chute for the initial
deployment.  It free falls horizontally,  slowly enough that on several
occasions when the secondary chute didn=92t deploy, damage was minimal,
ranging from nothing to broken fin tips.

Also I use about .75g of black powder in the secondary deployment
charge.  With a 2.5" x 9" payload bay, it makes a big enough bang at
250=92 that even if you are looking in the wrong direction it draws your
attention to the great big Dave Fox chute.
