Here you can see the supplied carbon fiber servo trays in place for the throttle & 3rd channel servos. I will be using Futaba 3102's for both so the trays are trimmed accordingly (I added the wood strips under the tray tabs). You can see the anchor pad for the carbon fiber steering servo bracket as well as the small pedestal I added for the RX. Also visible is the 1/8" brass water line that I realized had to go around the servo after I had drilled the tub & went to line up the servo trays.
