Clevis,
I routed my antenna forward first, then to the rear of the plane. Don't do a loop back to the front around your servos....... Not the best thing to do. I'm using a Zenoa g-45 also. You can get a prop bolt that is drilled and tapped so you can use a good grade of spinner (Vortac or True-Turn) or you can use an open end wrench to tighten the existing bolt between the two metal supports. Good luck and take heed to all the other posts about upgrades and safety changes on this bird. The 45 will make this a pretty peppy plane and you wouldn't want to lose it because you didn't do a little light reading! Let me hear how your first flight went after you are done.
