I´ve used the FY41-AP Lite here
It´s most certainly not the best on the market
or with the most functionality
but I think it´s a good bang for the buck
It supports Return to home
has GPS
a pitot sensor is included
I´ve fitted it here, not the best position though
with it you can measure the relative air speed
that flows over the wing
It´s practical if you´re flying in strong winds
you can directly see if you´re having head or tail wind
With that information
you´re not going to stall the plane as easy
especially if you´re running a low autopilot speed
I won´t cover the FY41 in detail here
there´s enough videos out there
The next best option I would have chosen
is the Eagle Tree Vector or MyFlyDream
They are most certainly even a bit better
They support antenna trackers
But for now, this is sufficient for me
Let´s have a look from the tail to the front
The powertrain
Many of the guys in the internet are flying the SunnySky
with an 8x6 prop
But also many have reported
that if you want to fly more than 5200mAh batteries
it is quite hard to hand start
Therefore I decided
to fit a stronger powertrain
This is a Turnigy 3536 1000kV
with a 10x6 screw
I´m still testing whether 9x6 is maybe more efficient
I´m still changing back and forth
The motor/prop combo is very solid
The ESC (Turnigy Plush) is totally unchallenged
It´s 60A, but 40A should be more than enough
I´m quite happy with the powertrain
Even if I fly with 2 5200mAh batteries
which I´ll show you in a minute
it starts quite well
and with only one 5200mAh
it just pulls it out of your hands
So Hand starting is not a problem
Let´s have a look at the servos
I looked around in the Internet
I was searching for a good value for the money
And many have recommended these
They are the Emax ES08MA II
They are quite solid analog servos
with metal gearing
they never have let me down
They may be not the fastest in the world
but have good centering
For what´s needed on a plane like this they are sufficient
I´ve fitted them everywhere (ail, ele, rud)
For the RC controls I´m flying the TBS Crossfire
I´m quite happy with it
Never flown anything other, but
it´s plug & play
has many nice features like
dynamic power
telemetry on your Taranis
so you can see or have audio feedback about
the signal strength
There´s nothing left to be desired
There´s also constantly updates for it
I guess that´s what differentiates it
to more 'old-school' systems
like Scherrer or EzUHF
For the video connection
I´m running a 2.4GHz system
That frequency is now free to use
as I´m running UHF for the controls
I´m running an ImmersionRC Tx
And a Lawmate receiver
and completed with antennas from Larot
They are not available in their shop, but
you can write to the manufacturer (Lars)
then he´ll build them for you
What´s also important:
I´ve got a redundant power supply for the servos
These are Schottky diodes
They enable you to run two BECs in parallel
so that when one BEC is failing
the other one takes its job
So now, even if the whole ESC and its BEC fails
(this is what happened to me once)
then you can still do a controlled glide to the ground
Now I want to show you the battery compartment
These are the 5200mAh MulitStars
They´re quite cheap
I bought them for ca. 20€
They have a low C rating, but
for this plane this is more than enough
10C means they can deliver 52A constantly
I don´t get to there with this setup
When cruising, I have a consumption
of ca. 6A at 55 - 60km/h
And if you´re throttling up
for ascending or just for flying faster
I´m getting a maximum of 25-30A
This is how I´ve done it
I can fly with 1 or 2 batteries
Here are the 2 XT60 connectors
If you´re flying with one battery
(depending if you´re having a heavy front setup or not)
you might have to push the battery completely to the front
For my setup
I have marked the different positions
so I know the battery has to be right here
I´m still testing everything
There will be LiPo straps fitted in the future
but for know it´s going well with the velcro
The velcro has never failed on me yet
And when I want to run 2 batteries
you´ll have to put the second LiPo here
push it right in
and now you´ve got 2 5200mAh LiPos in it
Always remember to check your center of gravity
That´s how you get 10Ah for this plane
AUW this would be ca. 1900g
but the Mini Talon can handle this weight with no problems
With 10Ah you can fly
quite long
at least 1 hour in the air
and with good throttle management
maybe 1:15 to 1:20
