| Building thread of SX3 (SouthernX-3) from
Norway... This is a page that tries to collect some info
and building instructions about the SX3.
Here are some links to start of with:
I have made a page I copy all the info I feel
is important when building
LOOK HERE
This page follows me and my friend Arild's
building and flying
The following txt is from my
diary
DAY .. 9. January 2005
- On the ice and removed some snow. Afterwards I
had a spin with the SX3. It was a small wind that came and went
otherwise I would have set up the winch. Maybe tomorrow... Few
propellers left so I fitted a 9x6 Graupner I had laying around.
Great power but not good enough for hovering stable. Need lower
pitch...

DAY .. 5.
January 2005
- Went out for a club meeting (inside...) and had to fly
some SX3 and 3DX mini indoor. Video of the
SX3 indoor
HERE (10mb .wmv). Beginning to get better at hovering but that wall
never attached to the SX3 and that door was difficult to get thru :-)
But with the 3DX mini I at least managed to get on that door... I did
not dare to go thru the door since it easily get damaged (only depron).

3DX mini HERE (7,7mb .wmv).

14. December 2004 SX3
Today we tested the SX3 with a heavy setup just for
fun. Arild had a Mega 400-15/5 (63g) and with 10x4,7 and a 2x2000HD pack
(100g) this draws 20A and extreme power. It was too heavy for indoor
flying for sure. But for outdoor normal aerobatic it was ok. The weight
was just above 400g. So the SX3 can take a bit more weight but it flies
best when the weight is low. Kind of cool today that I actually flew
with 3 different motors in my model. The AXI in the morning, the Mega
mid-day and finally I attached my Klepaker Extreme in the afternoon in
the dark (I have also lights in the fuse). Since the AXI is perfect for
the Lierider I will fly the SX3 with KE17 (Klepaker Extreme 17turn).
This gives me a bit more power and the same weight.

13. December 2004 SX3
Finally - or maybe not finally since it has gone
pretty quick to build the new SX3 (SouthernX3) in EPP. We were the first to
order a ARF SX3 and probably the first to complete one :-) Lets say it
immediately: I am very pleased with it and did just what I expected from a
"soft" machine like this. It hover, flies knife-edge, knife-edge loop (Arild
did two in a row), very nice loops, rolling circle (much better when we get
the diff. correct) and probably all other 3D stuff you can think of. If I
were to set my finger on something it will be: - one needs 3M77 spray that
is almost as expensive as half a model. It is an ARF so maybe the parts that
need this should be premade. The fuse tail was also a bit difficult to get
straight but if one adjusted a bit it was ok. - The hinging is difficult but
did work out ok after a few mishaps. - There was some carbon in the set for
pushrods. This can just as well be 1mm piano since the servos will is right
by the control surfaces. - The colours were....
A few tip: - motor angle is 0 all ways (maybe slightly down but not
meassured). Arild`s had a bit up thrust and the
model became strange. - Use lots of time on hinging and pushrods. Lots of
travel = fun. - First tests showed a bit too much differential. We have the
ailerons servo on top with no angle on the horn. - Use 3M77 on all places...
Makes it easier to work and the tape sticks to the EPP. - To join the top
and bottom of the fuse I now like to have packing tape first and the join by
a smaller clear tape. Then you can adjust if you do wrong. We first used
glasfiber tape but it is hard to get off if you want to adjust. - EPP seems
to be ok with all kinds of cyano and kicker. I used thin cyano many places
with kicker and liked it.
Maybe I remember more later :-) We also
did some lights. 2 bright 10mm LED`s (1,7v, 20mA 300mcd) were made in series
so that they could be plugged right into the receiver. Strange that they
were marked with 1,7v because at that voltage they dont light.. Must be 3v
that were packed wrong I think... Anyhow we cut the hingeline and had one in
each wing and made a plug at the servo end since we are using 4channel
receiver. Will have two led`s in the fuse also that can be plugged in when
we want. You can just see the lights in one of the pictures... It was cold
so we did not fly long (I flew 750mah of a 3 cell pack) and my model is
217g + 55g battery. I used the AXI 2204 while Arild used a powerful LRK.

The cooling is taped because it is winter... The nut at the wheel is a
normal 1,8mm nut

11. December 2004 SX3
SX3 have arrived....
Building thread started
Arild thru all away and jumped in the car as soon as it
arrived... Guess we have been waiting for this one :-)
