Here is the Xicoy gear/brake controller mounted just behind the CG in the left wing root. I made a tray such that the controller can slide out after the single screw at the engine mount board is removed:
Note that it is easy to remove the screw, slide the controller out and access all connections and the display. Once all is tuned up then slide it back into position and the single screw secures it solid. I similarly mounted the air trap and the engine fuel pump. They both slide into the side and then a single screw secures each one in place. I always like things to be as easy as possible to service.
No wasting of popsicle sticks.
Next I will show you a new tool for drilling in tight spaces. You are going to love this one !
