Got the rear formers in place and installed the antenna tube...
The instructions state to glue one end into the servo tray and then bend into position. Did it a little differently. Bent the tube slowly while holding over a gas stove burner to heat the plastic. Once I had the desired bend I put it under running cold water while holding the shape just a little past. Rx wire fits fine. The bend didn't collapse the tube much at all - worked great.
