Ok, thanks! Is it ok if I put both the aileron control wires in one hole or do I put them into two adjacent holes?

IF you are using them for the Ailerons, it is probably best if you use the Servo Arm you circled

I do not think you can get Both rods into one hole

IF you put in separate holes you will get more travel on one than the other

I missed your post where it said "aileron"

All of mine have the little servo arm, except the servo for the ailerons

Unfortunately I don't have the type I circled, since I got the kit without any electronics. I do have a servo with a round servo arm that I could use. Will that be ok?

Where the Aileron servo sets There is no room for a round "arm"...there is just a slot there.

You can try to put both control linkages in one hole....it will work if you make the hole larger on that smaller arm .

the way i have found easiest to do that is, I use a large sewing needle hold it with pliers...and heat the needle and then insert it in the hole to enlarge the hole to the right size without making it to large or cracking the plastic.

If you've got some modelling ply or even old credit card or similar plastic you can modify your own arm like the original one. Just cut little larger piece, drill those two holes and then glue this to original single arm and use couple of small screws to ensure that it will stay fixed...

You just need some very basic tools such as knife & small drill.

I've done several extended arms using this technique.

HGhost and Late99:
Some very interesting ideas! I can do that with CC plastic. (I have also found a simple way to use a cheap, readily available 2212 motor with the spring mount, which I will post later)

Ghheee!!! Yak12 PNF on backorder in Europe as well as Int.warehouse!
But they have the ARF/kit-version, so maybe that's a way to go.

* Standard 9g servos fit nicely everywhere?
* Any info/advice on alternative motors? The HK-suggestion D2826-6 2200kv is supposed to give 342w/34A - isn't that a bit overpowered?
* Also reads like fitting alternative motors is a bit awkward - any advice?

Thanks!

1. My simple solution to the motor problem. Here I have a 2212-2200kV motor. I used two shims (arrow pointing to one set) and a longer mounting screw through the 16mm holes in the motor. The shims lift the motor can away from the mounting plate, allowing me to use my $7.50 motor and prop adapter, rather than the expensive 2226 motor that is difficult to find.

2. 9g micro servos will fit, but you will need a special servo horn for the aileron servo wires (see my posts and the solutions proposed by HGhost and late99). You could also get the copterx 9g servo which has that type of horn.

3. The kit has 2 props which you can't use unless your motor has a 3mm shaft for the included prop adapter. So you will need a collet type adapter for your props plus props. I will use 64e props.

4. For the ESC I am going to use a YEP 30A.

If you are a true newbie, I would suggest wait for the PNF to come back in stock instead of getting the ARF.

...or does anybody has another suggestion for a rather small newbie-plane that can easily be handlaunched (bellylanding is also OK)?
My SportsCub S is so light/small it's very sensitive for wind, so a slightly larger plane was what I was looking for when the Yak12 came up - and then disappeared into the backordered items...

Well I use the E-Flite SAFE Reciever in multiple planes, so almost every plane can be a beginners type plane .

I have an array of planes, I like the size of the Yak 12, and it is hard to find good planes in that size most are always larger or far smaller

The Wilga is a very nice plane it has flaps, it flies much like the Yak 12, it is the same size

The Hobby Zone Super Cub is a nice plane-but it is 3 ch and has SAFE
Also the Delta Ray is a nice plane it also has SAFE but has brushed motors
The Apprentice or the Sportsman S Plus...but both are very large.
Hobbyzone Stratus

just depends on what you are looking for.

Like HGhost said, you could get the Hobbyking Wilga (fraternal twin of Yak 12). Or check the Hobbyking Sky Easy (1050mm pusher prop belly lander) in my opinion the best looking pusher prop out there.

I just snatched up the last Yak 12 in the East Warehouse. A friend of mine got one of these about a year ago, and we had a ball seeing who could keep it in the air with full flaps and under 2ft altitude. With the stock setup, we were getting close to 20 minutes flight time on a 1.0Ah pack. Friend has drifted away from our flying circle of friends, so its time to get my own to park next to my little Wilga.

Maiden flying session with the Yak12 this morning. I had eight 1000mah batteries with me, but I only flew 4. Timer set to 12 minutes with mixed throttle. I swapped the tiny stock tires for some 2 inch units I had in my scrounge box. Had to take the dremel to the hubs to get them to fit on the short axle. Plane flew great.
