well as I have not flown much due to laziness and weather mostly
My last outing was FPV on a UMX Sport Cub S ......
was very fun to do that , enjoyed it a lot
Only issue with the UMX is the wind even smaller winds can push it about
So I decided to break out my New Yak 12 and retire Ol Franken Yak
as he would not turn right without becoming a lawn dart
did not know why at the time
this video link shows that -
www.youtube.com/watch?v=vuR4i-oDUKg
Anyway....I took Ol Frankie apart and stored the fuse and wing away just in case ( it had been battered )
put the New Yak together did very well
But , I also learned the reason for Ol Frankie's issues ( I think )
for some reason I used a extension wire on the ailerons and as I put this new Yak together
I had to install flaps as this one did not come with them .
I installed everything and hooked up that same wire to the flaps ( as the ailerons do not need an extension)
and as I was trying to set them up...the wire worked intermittent and wanted to turn the servo one way and not the other
I disagreeumption is one wire must have a short or intermittent issue as evidently did not allow one aileron
on Ol Frankie to work...( as I also use Rudder all the time in turns ) it would turn some with rudder, but when
applying RIGHT Aileron it was not working and thus sending me into the ground ? Well that is what I think...lol
anyway a new extension on the flaps , they work perfectly .
all systems go...and I ran up the motor before installing cowl and prop..however
once the cowl and prop was installed I now have a Vibration and it is really
noticeable ( I have that SAME style Vibration ) on my Wilga ..changing a prop did not help it
and have not figured out the why...I fly it like it is..BUT with this Yak I want to use FPV
and do not want the camera to have that vibration bouncing it about and causing bad video
Now I have to figure out what it is ( I still have all the Frankie Yak parts it never had that vibration )
may have to change motors.
But also this Yak came with weights already installed in the nose area under the motor in the foam
The old one ( Frankie ) had a hole in which I placed the ESC....and with the new one that hole is
filled with weights, I just mounted the ESC flat underneath the motor and taped it down, makes the cowl
tight ( may be causing the vibration perhaps ? )....on Ol Frankie i had to put weight on either side of the motor
to get the CG correct....this one has weights mounted for that purpose already it seems ( will do a CG check later )
funny how the same model has different things even from the same manufacturer . O well...is what it is
I enjoy the Yaks...sad to know they are not being made anymore
it is an excellent flying plane and is so relaxing and enjoyable and just the right size
to throw it about in my Unique small field .
SO...that is where I am this New Year...laid the Yak aside a few days will do some vibration inspections
and CG set up in the coming days
Hope many of you are getting some air time...as I now watch it snow a little ..again...LOL
Chris , waiting for some more vids....keep them coming
