I recently picked up a Parkzone Focke-Wulf 190A, which is now ready for its maiden flight after I applied some minor enhancements.

To aid visibility and to make the model more attractive to my eye, I painted the rudder and the underside of the wingtips to match the yellow on the underside of the cowl. I got the paint from local Home Depot, who scanned cowl to match paint perfectly.

Installed an Eagle Tree Guardian inertial stabilizer to improve stability in windy conditions and assist hand launching. The combination of the yellow highlights and Guardian should reduce potential for crashes caused by disorientation, the highlights by making the model easier to see and the Guardian by providing a self leveling mode at the flip of a transmitter switch if orientation is lost.

Installed a pair of wing skids near the aileron servo arms to protect the servos from stripping if wing were to strike ground during a belly landing.

I'd be happy to provide more detail in this post about the Guardian installation and configuration, please comment if you're interested.

Because we fly from a grass field that's incompatible with our Parkzone Spitfire's landing gear, whether fixed or retractable, we hand launch and belly land it. Occasionally the tip of one of Spitfire's wing mounted cannons will catch on landing and pull it off the leading edge of the wing, leading to minor damage. To prevent this, we cut the cannons, which are hollow, and installed within them N45 3/8''x 1/16" magnets, which are held in place with epoxy. These magnets are strong enough to hold the cannons in place while flying, but weak enough to allow deflection when belly landing.

No flying today, we have a nasty winter storm in progress, but we got the warbirds out of the hangar for a photo shoot by the fireplace.

Here's a photo of an Eagle Tree Guardian installed in my son's Spitfire and some screen shots of its settings. Also attached are the Guardian and DX8 settings files. Note that the Spitfire is not the roomiest bird, installation in my T-28 was much easier, but it does fit in the Spitfire.

The Guardian is mounted to the top of the wing within the fuselage near the front of the belly compartment. This gets it out of the way of the tail servos and also allows access to its gain dials from the battery compartment. The receiver has been relocated to the right rear corner of the battery compartment. This limits how far back the battery can be slid back, but I found no problem obtaining recommend CG using 3S 2200 mAh batteries. A layer of clear packaging tape, much longer and wider than the dimensions of the Guardian, is placed on top of the wing, followed by a strip of Scotch Heavy Duty Fasteners that is slightly larger than the dimensions of the Guardian. These two together provide a stable base for the Guardian which is attached using another strip of heavy duty fastener that's cut to exact dimensions of Guardian.

The Guardian's mode input is connected to the receiver's Aux1 output and Guardian's master gain input is connected to the receiver's Gear output. My DX8 is programmed (see SPM attachment) to control the mode using the 3 position Flap switch and the gain using the knob. With the Guardian's gain dials as shown in the General Tab attachment and the DX8's...Continue Reading
