When building my US60, I noticed that the grain of the approx 1/4" thick balsa center section of the horizontal stab runs lengthwise with the fuselage. This is the part that is glued to the fuselage, but some of it is visible on either side. Normally the grain on models runs laterally for greater spanwise strength and to resist deflection. I don't know if this is typical for this model, and know of one manufacturer who has a standing rule with their factories to make sure it only runs laterally to avoid tail failures. I once had a plane with the grain the wrong way and this failure occured.

I am thinking of adding tail struts for some insurance.

1. Has anyone else noticed this? Which way does your grain run?
2. Has anyone had a tail failure such as a cracked leading or trailing spar?
3. Anybody add tail struts or flying wires?

Also, since I'll be using a YS91FZ, which is heavier than the Saito 91 or 100, I definitely want the servos in the rear. Was planning on the pull-pull setup like Termagator posted. Definitely for rudder, but not sure about it for elevator. Worried about it snagging in the grass I fly off. Thoughts on this?

Thanks
