I installed a new Futaba GV-1 governor in my basic,
but trusty old Shuttle ZX and flew it yesterday. I
can't believe what an improvement it made!

About a year ago I scared the heck out of myself
when I apparently miss programmed Flight Mode 1
with a "U" shaped throttle curve and some negative
pitch. I got a big rotor over speed. Since then,
I've stuck to just flying in the Normal Mode, which
is limiting. On my second flight with the governor
I switched to Flight Mode 1 and gingerly explored
the collective range. All was well so I did my
first loop! By the end of the third flight I had
completed at least a dozen loops and even added
some negative collective while going over the top.
It was so easy it seemed anti climatic. Rolls
next week? :-)

Ahh. that wonderful feeling of progression eh? Now remember NOT to touch
that tail rotor stick during that first roll, ESPECIALLY if you're using a
HH gyro.

I saw a SUPERB bit of aerial gymnastics when a pal pulled in a armful of
left tail when he yanked back on the collective during a roll. I'm still
trying to think up a name for the "manoeuvre" :-))

After being on a plateau for a long, long time,
it does feel good to progress. I wish I had a
HH gyro (hope to get a GY-401 soon). I'm still
using an old, mechanical JR 120 BB something or
other, but I'll still take your tip and stay off
the tail rotor. Guess I better double check the
REVO settings for negative pitch realm :-)

Sounds wild. If it was a plank it would probably
be called a Lomcevak, or something along that line.

If you're still using a mech/elec, then it's not QUITE so bad, coz when you
let go of the tail rotor command, the heli will instantly fly "nose
forwards" again. That doesn't happen with a HH. Regarding your choice (GY
401). Good gyro, but if you buy it (and a GOOD servo) over here, it's as
expensive as a CSM SL560 with a good servo and it's NOWHERE near the gyro
the 560 is.

It was scary. I think it'd be called a "Keck-wrecker" :-)

I found some information on the CSM SL560 that you
speak of. Question: what does "stop performance"
mean?

If you link the gyro to a puter, you can select a variety of menu options
which are used to fine tune the gyro's performance. You can stop any
"bounce" that normally comes from having a servo that's too slow, or even
overcome a fair amount of poor tail boom support (movement) which causes
all sorts of aggro.

You can also dictate how far the tail steps out of line before the gyro
brings it back INTO line, which also aids stopping performance, and how
great the correction is. No other gyro has the facility to hook it to a
puter either, but having said that, the VAST majority of installations don't
require the gyro ever being linked to anything other than a Rx and a servo.

The default settings within the gyro are excellent.
