    With temps in the nineties this weekend, the workshop will be my refuge and the Fox my project.

    I didn’t want to be completely rudderless this evening so I got the fuselage back on the bench and installed the rudder.

    And a nice rudder it is. Lightweight!

      After a morning of yard work, cool down mode was some fun with dolls and arts & crafts. Some legectomies and butt reductions were in order.

        Then on to the less fun stuff of trying to get as much weight as far up front as possible.

        I realized my plan of a single 6S 6000 pack would require in to be in the middle of the cockpit area while two 3S 5500s would fit nicely to either side of the motor with the speed control tucked directly behind the motor. It all fits and the ESC can breathe.

          Located the Pioneer, receivers and all the related wiring. One receiver up high on the elevator/rudder tray to the right side of the plane, antennas pointing backward at opposing angles, the other forward on the left side of the fuselage one antenna vertical upward and one horizontal pointing ahead.

          Still need to decide where the switch will be located?

            Don't forget to give the passenger, usually the person in the front seat, a barf bag...

            I hate floppy canopies. On this model, they go all the way over and hit the side. One big gust of wind if they unlatched in the pits and they can snap right off. My solution here was a couple simple leashes using 0.032 Kevlar cord.

              Not much time today to invest in the workshop. Project number one was to get the RC system batteries mounted and then a quick project to hide the rudder and elevator servos from view.
