Re: Blunt nose...

Yeah the Yak slows pretty quickly and as a 3D plane you usually want more power than say the Lancair.

Re: Tail issue.

The tail planes will rip off in high speed flight at high deflection when you abruptly change the stab angle.

If you see the advertizement they even state that they have reinforced the tail...

However you'll find a couple of posts about this in the NP support forum.... they didn't strengthen the stabilizer cross member by switching to hardwood.

This can be fixed by opening the stab before installing it, and replacing the cross member ( where the CA hinges go into ) with hard wood.

I had a 3D Passion with exactly the same problem.

I don't know if you can solve this by poking a bunch of pin holes on the cross member, top and bottom then wicking in thin CA.

This may work as well.


I've often done this on planes to harden certain areas.
