Assembly before sanding. -

Spinner after sanding. I used a short section of 5/32" diameter music wire as the shaft, chucked in a table-top drill press. Slide the sanding assembly on the drill press table while pulling gently down on the chuck handle. -

I took a photo from the www of a RC 7-cylinder model engine, singled out the best cylinder, and copied that around the other six cylinders. This picture is full size to the Bobcat. -

Looking straight out at the field from the parking lot. A half mile directly ahead is the north end of Lake Samammish. -

It may be sacrilegious of me, but I can't recall who Mr. Sands was. The rear of the frequency shack facing the parking lot. -

Note the full-scale wooden propeller on the mantle of the frequency shack. The field sits on the NE border of Marymoor Park, which is huge. -

Electrics guys charging station. Nowadays, that's most of us. Note the weather station in the upper left of the pic, which keeps the club's website weather details current. Maybe I should have checked there instead. -

East end of the flying field from the pit area. We have five flying stations in all. The grass field is cut to about an inch in height, and regular rolling keeps things smooth. It's fully irrigated to help combat those dry summers. -

West end of the field. On a clear day, you would see the top half of Mt. Rainier in the upper left of this pic. The big geological pimple sits massively to the south by about 90 miles, looking like a chunk of the moon fell off and got lodged there. -

40 inch ws foamy Super Sportster. I took out the weak stock 400-size motor, and stuffed a Rimfire .10 under the hood. It's got an inch larger propeller, no landing gear, wing servos on top, and a full-length wood spar. It's easy, fast, and fun!

I used 3/32" sheet aluminum on top because the wood by itself was getting burnt from the hot piece as I was grinding it. -

You can see that the most accurate measurements happen in the smaller central area of the picture! -

How square it is! -
Views: 332
The prop is centered so you can see that you have 1-1/2" of ground clearance. -

The wheel hangs down nicely like the full-scale bird.

Cut out the inner portion with the strut template, and attach the outer part at the front. Cut wood from center until you reach the NF1 inner ply frame side. This is how you square it up. Trace around, and cut out. -

Pull down on either side with thumb and forefinger to get the template to lay flat and straight against the nacelle. -

Final rough cut-out. I checked this with the wheel on the strut assembly, minus the flat spots, up and down. -

I used the strut template attached to my vise to guide me when bending the 5/32" diameter K&S music wire in a K&S Mighty Wire Bender/Coiler that I got from Tower Hobbies. -
Views: 348
You won't need to get the strut bent perfectly with the Mighty Wire Bender, but you'll want to be close. The rest is tweak, tweak, tweak, in the vise until you do get it perfect.

The Rimfire 10 motors had to have their shafts reversed for the type of spinner I'm using. Their shafts are indeed reversible, having three flat spots ground in. I used a small section of 5/32 " music wire to displace them. -

I needed 5/8" of stand-off to bring everything out to the front of the cowl. I used a square piece of 1/2" poplar and one of 1/8" plywood in combination, drilling to match the inner holes in the X mount. My replacement M3 screws were 25 m -

It took 3 washers at about 1/32" thickness each to get the motor centered. I supported the surrounding two X mount arms with one washer each. The lines at the center were drawn in Photoshop Elements to show that I'm close enough for my own liking. -

I did a screen shot while in Photoshop Elements to show you all the little black box that says the angle of the prop is at -178.5 degrees, which makes the thrust on both sides offset to the outside by 1.5 degrees. Port = pusher, Starboard = tractor.

I'm using strips of masking tape, cut in half lengthwise, to hold down two planks at a time for a nice, tight fit. -

The majority of the glue I use on the skins is wood glue (aliphatic resin), with medium CA on the longeron and outer edges of the formers to lock the piece in place.
