RE: Spinner weight goodness
The first photo shows all the equipment placed as far forward as possible. It shows the battery pack I made to fit the space, and the receiver which are both in foam. the valve and servo for the retracts. Below that is the servo tray which has a mylar cover to prevent any wires getting into the arms. You can see the underside of the cut off legs of the pilot, and finally the airtank pushed as far forward as possible.
Next shows how the ducted fan is mounted and the separate power switch for the LiPo. The ecs is inside the mount.
Next is a front view showing a baffle that helps direct the air flow to the intake of the DF.
The next photo shows the LiPo battery for the DF velcroed down on top, the microswitch that controls the onboard glow which is activated by a wheel collar on the throttle arm and the NiMH battery.
Finally is a photo of the intake baffle in the cowl. Air is drawn in from between the spinner and cowl, is baffled up against the cylinder, passes over the crank case, and then exhausted out the rear by the fan.
