The Corona swashplate exerts sheering force on the balls to transfer deflections of the servo pushrods to the rotor head. The inner part is stationary and connects to the servos. The outer part spins and connects to the rotor head. -

To compensate for wear, they divided the outer part into an outer race+race ring which can be expanded or contracted. -
Views: 431
The swashplate was feeling a bit too lose and looking a bit grey from metal filings. -
Views: 409
Grey grease never looked good. -
Views: 404
The grease mixed with a bit of oil from our attempts to lubricate the pushrods. -

A handy dandy NdFeB magnet+paper towel pops the balls right out. -

As grey as the Calif* sky. -

Predicted darker grease from metal filings but it was suprisingly light.

Camera's view of the successful landing. -

Landing platform 6 was a complete mockup of the camera pylon and 2' tall skid platform. It only had to last 6 minutes. -
Views: 466
The skid platform was out of ground effect. -
Views: 468
The approach to landing platform 6 had a wider opening than the exit.

The Bell/Hiller is a mechanical averager. One end's height is set by the swashplate. The other end's height is set by the flybar. The output height is the average of the swashplate and flybar heights. -

Custom swashplate input rod. Avoid beheading by not doing this and only using official parts in your 1700rpm rotor. -

Custom Bell/Hiller rods with markings to aid tracking and of course, it flew. Avoid beheading by not doing this and only using official parts in your 1700rpm rotor. -

This view of the stock B/H assembly also shows the Jesus bolt, supporting the entire copter's weight, so named because if it fails the next thing your copter sees will be Jesus. -

Not sure where this one came from. Could never have planned it. Looks like a wish by some country that's never going to happen. Was a low altitude pass followed by climb but the shutter closed at just the right moment. -

Meet the Pelosicopter. Had to point downwind for these shots and fight to keep her from turning around and attacking. -

Views from the edge of space brought 2 U by the copter. Highest altitude so far. -

Camera mount #7 was an upside down camera on the table. The camera was too loose in this position. -
Views: 391
Padding on the skids was reduced to expose the LEDs and get tighter contact. -

It's the copter poodle U might say. -

Way too far away. -

Sorry that it messed with the U. Know. of Where. -

5 second exposures, low altitude passes heading in and out in front of Orion should look best.

Couldn't afford a 5D flashlight so built a 5D harness out of a 3D light and aluminum. -

The lightbulb was made from a halogen and a conventional bulb in Nov 2005 and hasn't burned out yet. -

It is critical not to bend the halogen leads during fabrication or it will explode when turned on. -

The Futaba horns are not as optimally sized as the Hitec horns. Either too long or too short. -

The Futaba with really short wire and crazy connector -

4 brass & 1 nylon in the Futaba gearbox. 180` only. Recall Hitec has a steel main gear and a much lower reduction in the final step. -

Electronics wrapped up. Decided against redoing the heat shrink tubing and splicing the cable instead. -

Periodic noise in the camera audio showed the rotor speed. Audio analysis is impossible in high wind.

On the first night camera flight, only downsampling to 320x180 could get enough dynamic range to see anything. -

If U don't know where this is going, grow a mane. -

Based on the experience with the swaying halogen, tried to stabilize it with 4 strings. -

The result of this was of course, horrific. -

Made the camera table smaller and made a fillet to overcome the cockeyed lens. -
Views: 389
Making a balsa fillet to tilt the lens down was brutal. -
Views: 429
Who knows what the camera designers of Japan have in mind to torture us with in the future. There's absolutely no reason for a camera lens to be tilted.

Serious, unbelievable wind. Take a look at the flag. U know the one. -

Didn't intend 2 get into this situation, but the flag tells the story. -

Nose-in high altitude? No problem if you practiced with the LEDs. -

Ground a flat in the tail drive shaft. Much stiffer now, but if the tail ever jams it's going to grind up the shaft nicely. -

Also have some spinning rotor shots with the lighting. Contrary to the Canon's view, the blue LED seems 2 B fading. -
Views: 450
Another shot with the blade tracking emphasized. Every time this copter is moved, it shifts in or out by 1 turn so we don't bother trying to keep it within the last turn.

It isn't what you think. RW & B are the only LED colors we have in the dumpy apartment. -
Views: 347
Replaced some white LEDs with red & blue to help orientation some more. -

Unfortunately blue is almost indistinguishable from white on this copter. -
