The prop adapter is attached to the motor shaft using the supplied grub screws. Be sure to align the screws with the pre ground flat of the motor shaft. I also like to use a little blue Loctite 242 to make sure things don't come back apart on their own.
A little more 242 is used inside the threaded holes of the motor before attaching it to the fan housing with the provided screws. Take note of the wiring orientation in relation to the molded lugs on the fan housing.
A little more 242 into the threads of the prop adapter and the impeller is slid down over the shaft. The included srew is threaded in securing it and it gets tested for operation before proceeding.
The wings came with the elevons pre-hinged and the control horns pre-installed. A nice feature. One thing I didn't like was all the mold marks on the bottoms of the wing and one side of the vertical fin.
So, I did a bit of sanding to smooth things out and added some lightweight spackle in the low spots.
Another nice feature is that the servo extensions for the elevon servos come pre-installed in the fuselage.
Another feature I liked was the way the wings and fuselage have interlocking tabs that almost guarantee proper alignment when attaching them.
Wings have been attached with 30 minute epoxy and low spots along the seam filled with light spackle.
Although 1st flights will be done with landing gear, plans are to make this into a "belly flopper" so the entire belly pan is "glassed" with 2 oz. cloth and minwax poly acrylic. The bottoms of the wings are also glassed using 3/4 oz. cloth.
It's not visible, but there is a 60 amp (overkill) Turnigy ESC attached to the top portion of the ducting with Velcro. A single strand of cat 5 lan cable is then used to pull the servo lead through the channel where the elevon extensions were pre ran.
Also to pull another servo extension for the rudder servo I added to mine.
After connecting the elevon servo leads, the fan is inserted into the molded cavity. The lugs get pressed into the foam until it fits flush. Expect to have to work on the fan hatch making depressions for the lower housing lugs as well. These tabs will keep the fan from spinning inside the foam though.
I made my esc to motor connections through the opening in the top of the fuselage before attaching the vertical fin. With my big hands it's about the only way to do it.
I hollowed out the underneath of the vertical fin a little using a hot wire for extra clearance on the wires. The rudder servo is plugged in to the extension and then the fin get's attached with 5 minute epoxy.
A shot of the AR6100 receiver and nose steering installation. I used the hot wire approach again to clean out foam for the 4s 2200 ma lipo pack. (A piece of metal clothing hanger bent to the size I wanted and heated with a small butane torch. Crude, but effective).
The finished model as flown in the review video. Unfortunately with the landing gear installed it's a bit nose heavy with CG at 150 mm from wing leading edge. The manual makes no mention of correct balance point but did find a thread in RC Groups that said it should be 170-180 mm from wing leading edge.
