Online-support build-up. Page 11 Un-painted Gallery.
Set-up: In
the Uni 2000 instructions it is suggested that you run 6.5- 7 degrees in
the hover for slow speed
hovering. I found
that 6.75 worked quite well and produces a crisp cyclic at a 1200
rpm head speed. I set the
stick pitch to 12
degrees and the low side to negative 4 degrees. 13 degrees at full stick
for autos. I started
with all linear
curves and only a little tweaking was needed on the pitch, adding a little
extra on the lower half
of the curve to
slow the descent somewhat. I run 9402 serovs for cyclics and a gy-502 gyro
with 9250 digital
servo for the tail.
9202's take care of the retracts. I set my gyro to about 75% rate for intitial
testing. Your tastes
may differ somewhat.
Since we are starting a new motor, we kept hovering to about 1 min intervals
followed
by shorter 30 second
cool down intervals. Do this for about 3-4 tanks... then slowly increase
your flying times
for the rest of
the first gallon, this should be sufficent to allow the motor to break-in
nicely. 20-30% nitro is used.
First flight ! :
Well, our photo helper was out of town and I have yet to master flying
and photography of that same
flying object simultaneously
very difficult, So better flight pics and full video is on the way soon.
How did I like the first
fuel? AWESOME, the
motor fired right up , I set the main neeedle to 2.5 turns,I left
the lowside alone. The machine
spooled up with
nice quiet sound followed by a big hushing sound as the 1800 mm disc coned
and lifted her to about
4ft. I looked at
the tail and it was rock solid smooth! I was very happy as I gave inputs
and realized that this bird was
responsive at the
controls , able to take higher winds and made a hushing hover sound like
no other machine I had
before... I pulled
nose in and hit the gear as it slowly raised up and tucked away, so did
my heart rate! This huge
somewhat bulky lady
had turned into a mean looking torpedo... the kind that carry lots of firepower
and troops!
I turned away ,
came about and landed the most scale approach i have ever done... first
the mains touch down and
as you relax the
collective the nose simply follows. Ground handling is exempliary as
a slight push of foward cyclic
gets her rolling
and the tail rotor steers her like an rc car!
Extra tips/ FORWARD
FLIGHT: From the linear throttle curve I found it nessacary to increase
the throttle below
mid stick to maintain
rotor RPM during descent, there is SO MUCH lift in this rotor system that
it really needs some
help coming down
instead of climbing! Also I shaved a little of the pitch curve below mid
stick to help with this also.
A governor will
help these settings, but I believe that you cannot totally rely on electronic
devices entirely, it is good to
know how to set-up
your model without the aid of these devices... this way is something should
fail, the proper
programming is in
place. Oh yeah, I turn off the heading hold as it is not needed... you
have to fly the tail anyway
and it makes a better
pilot again not having to rely on devices to help him fly smoothly and
coordinated.
In forward flight
this helicopter is simply amazing in it's stabilty and grace...the speed
is exessive if you like it fast
but also flies so
slowly and smoothly that flybys are easily achieved inches from the deck
with total authority, the lift
and response is
smooth but instant and the tail response is awesome! In short this is my
favorite ship to date.
I love the the low
rotor rpm and the sound it delivers! Hey, add the long boom with these
blades in pod and boom
form and you now
a quiet heavy lifter! I will try this when I can begin painting soon and
have to pull the mechs for a
while.
