Got my F/A-18 today. I had to get the full PNP version from HK since the airframe kits seem to be unavailable anywhere...unless you're willing to do without a canopy and get the replacement fuse version.
It was easy to pull the stock DF unit, it had just a small amount of glue holding it in. The Wemo/Wicked fan and motor is a heck of a lot beefier looking than the stock gear (see photo)! I got the combo with the Wicked 5400 motor, and for a battery I got a Rhino 1050mAh 3S 40C. I'm going to put landing gear on it, using the molded-in servo pocket for the nosewheel steering servo. Hopefully the power of the Wemo/Wicked will make up some for the drag of the gear. I might even put the missiles on it (missiles on a Blue Angel plane!
When I place the Wemo shroud as shown in Don's photos, with the lip just touching the front of the gray plastic fan-cover attachment parts, the back of the motor will just barely clear the front of the bifurcation divider.
