A few of the holes in the elevator spars have to be countersunk, but the spar flange is too close. I took one of my extra countersink cages that I picked up on eBay and ground off part of the foot to allow it to get up close to the flange.
I didn’t like the idea of routing the trim servo wires through the hole on the left since the servo shaft (which is threaded) extends through this hole in the full nose-up trim condition. I’d much rather avoid the potential for chafing and drill another hole. Since there was already a lightening hole in the elevator horn, I just drilled a 3/8″ hole in the center of that. I’ll put a snap bushing in that hole later.
