Bought Cessna 182 from a LHS India based.
1660mm wingspan
1:6 scale
This is a balsa model but it's weight is more than i expected.
It's gonna be a Electric setup but they recommend .45-.65 engine, so 3.5-4Kg thrust motor or 1000W

Started with fuselage tail section
took measurement of tail and fin position and peeled off the monocote
Thin CA worked well for me
But be aware don't stick hinges before placing tail in place.

It's time for wing to setup.
Servo need to be installed but extension, so i soldered extension wire  and that's it pulled out wire through wing by thread.
It recommend using standard size servo (38g) but i have 16g so i stick it by Araldite
Added control horns

This post is dedicated to one of my best teacher Gp.Cpt. Shobhit Prakash who told me the easiest way to make a Z turn and from than it made my life much easier.
Those who don't know how to do it-
first mark the servo arm hole place by marker
then make a 90 degree turn
again make a 90 degree turn
........................................................
..............................................................
I can't explain it in words Sad
Just see in pic below

for removing covering from screw holes, instead of using knife i used soldering iron and it's doing great.
It's time to install tail and rudder servo, again i used two 16g servo for elevator and one 38g standard servo for rudder and nose gear.
Elevator servo assembly was easy, had some problem with nose gear wire (stock wire was too flexible so replaced it) but i solved it.

tail horns were little bit different than i'm used to.
cabin cover lock is wonderful, i'm going to use this in my scratch builds.
Battery placed, now i've to figure out to place some cousins around it.

Now it's time for wing struts.
According to manual wing strut holding screw should be 11cm from L.E. and 28cm from wing joining
so first strut join to fuselage and then to wing.
Struts can be turned backwards when not in use

Next is motor mount.
Motor mount is very simple to install and i have to say that it is quite rigid.

@antriksh,
Looking great!
One word of caution before test flight:
In the last pic in reply#9, we can see that the flap and aileron pushrods are connected to the outer hole of the servo arm, and to the inner hole of the control horn on the flap & aileron.

This is not the usual practice. Your present setup will give you excessive deflection of the control panels and possibly overload your servos.

Usual practice is to start with about equal horn length on servo and control. This gives 60 deg on the flap/aileron for 60 deg on the servo. Even this will probably be excessive. You may have to put the pushrod in the farthest hole on the control horn, and one of the medium distance holes on the servo arm.
Try it. It's easier to see practically than to make sense of written text!

I think in an earlier post you mentioned that you Araldited your (16gm) servos. The reason seems to be that your servos are too small for the space provided for servos (std, ie, around 40gms).

Please check the torque of your servos, against that of Std servos.
The problem is not just that your servos are smaller than the mounting space.
Your servos may be far weaker than required/recommended

Control overload due to pushrod positioning, plus inadequate servo strength is not a good combo.
Please discuss this with experienced flyers you have access to, or with others on the forum.
In aviation, better safe than sorry  Grin
Regards
