If you fly pattern then why get a Yak?

The Yak is really oriented towards 3D...

But given what you said it should do fine.

Re: Tail issue

There is one post on the NP forum where the pilot states that he was flying very conservatively when this happened.



I saw EXACTLY the same thing with my 3D Passion so I assume that he is correct...

I was doing a gentle loop when I saw my elevator turn into a ship's rudder...

I thought I was going to loose the plane... but I was able to get it down, since the other stab was still attached correctly.

I fixed this, went out the following week and had exactly the same problem on the other side!

I got it down again, and this time pulled off the stab covering and replaced the cross member with a hardwood one I made up myself.

I recovered the stab and haven't had a problem since.


I don't have that particular Yak ( I have the Fiberglass CMP 1.40 sized one instead... ).

The 3D Passion and the Yak 50 seem to be the only two planes with this problem so far.


If you do purchase the Yak I'd recommend that you at least use the pinhole/ca fix.

You could also make a few small holes along the hinge line and wick CA into them, avoiding the areas where you will put on the CA hinges.

Or you could put the holes in, put the hinges in, install the stab on the plane, and wick CA in all along the hinge area to strengthen it...

What I saw in the Passion and echoed by the guy with the Yak 50, is that the hinges rip out OUTSIDE of the area where the CA wicked into.

E.G. there is a lot of stress on the hinges, and not enough support...



Another solution of course is just to add more hinges!

I believe only two are used. If you cut down some CA hinge material you can probably fit 4 or 5 small ones along the stab.

That too will solve the problem.
