Just putting the last touches to my cam mount. 4 onboard servos and opto switch for trigger. Most are mounted in the lower carbon-fiber sandwich.

Have been using another version with the 1 axis swing, but this version now has easily adjusted damping on both. Cold weather changes the rubber elasticity at times.

Still have a few cosmetic changes to make. The design allows easy fore/aft balancing of parts and could allow for video and DSLR cameras with minimal changes.

The two top fiberglass rails are needed to clear the Vario belt drive housing. Other helis could use just one rail and make mounting even cleaner.

Impressive work Chris, Interesting to see the different ideas others come up with.

Any vibration problems yet to solve?

Thanks
Mark

Tidy looking job Chris!

One servo for each of the 3 axes, and the fourth for...?

4th servo is for zoom on the 7i, similar to 35mm SLR's.

Vibration has not been a problem, I have tried numerous methods and have settled on a loose mounting to the heli skids and rubber on the cam-mount rails along with the loose O-ring drive belts and accurate balancing of the pivot points.

I have been using double sided velcro with foam padding in the past but will go with the small bungies like many other carriers. Was afraid of falling off in the past, but with the light weight of the entire carrier, only bad landings stress the mount and attachment points.

Chris

PS the single pivot arms allow better access to memory cards and andvanced controls on the bigger cameras. Can be mounted from either side depending on camera type.

If you get the degree of clarity in your photos using the mount as you have given us in the photos you have posted illustrating it, you can't help but be happy!

That mount design is so cunning you could pin a tail on it and call it a weasle!

Some nicely engineered components.

John,
The roll axis works "around" the 20 degree angled arm. I have found that most photos are in the 10 to 40 degree angle of view. Still works at dead level and down to about 50 degrees. Straight down leveling has no effect. That is why the leveling is on a direct drive servo, set with the rudder stick (no spring centering on the TX). Pan and tilt are with unlimited rotation servos.

Longevity? Ball bearinged pivot points, cabon fiber frames, delrin blocks and solid fiberglass rods, 6061 aluminum parts, the 5/16 swing arm is pinned after final assembly. Entire assembly is sequentially balanced so micro servos could activate the belts if weight is an issue. You may be able to bend it but to break it would require more force than any camera or heli could withstand :-)

The "rails" allow the camera and battery/TX ballast to be movable and positioned "anywhere" under the heli.

My last unit allows for fore aft mounting and sliding the camera and battery ballast for the different CGs.

The single swing arm was needed to access the flash card slot. And the sandwich radio unit lent itself nicely to adding the zoom feature.

I have built several versions over a couple of years and always had strength as the primary goal. Now trying to reduce the size and weight a bit.

O-ring drive belts
Clever idea about O-rings.
Great job!

The O-rings are just easier to adjust. Resizing them is a piece of cake, just cut to size and CA the ends together. Easy to experiment with different diameters and tension. Plus added advantage of built in slippage.

Gears could be used instead, and direct servo drive can also be used as per the roll access. Also just tighten the belts and manually move the camera to the intended position and fly without a camera operator.

I like your O-rings idea because they will also dampen vibrations which is hard to get with gears.
Can you share the source for the o-rings and pulley wheels?

That is the best work I have seen to date. Very ingenious!

Do you have a laythe or a mill? Or was everything cut by hand?

Hi Bill,
I wish I had a mill/lathe. A table saw cut the curved parts on LG and bearing bar on sandwich. Drill press, band-saw, and sander did the rest. A dual track drill press vise helps for drilling spaced holes. The carbon is nice to work with but the dust is dangerous. Will probably go back to sheet aluminum.

I posted an AVI file of the mount and its swing and damping. Shows how the mechanical stabilization dampers work.

There are a few other pictures of old and new pieces of the mount in the /cam-mod folder.

Stellar craftsman ship to say the least. Have you had the chance to get her in the air. I know that I would love to see pictures when you get the chance.

Nice work!!

Was all packed up and ready for a shoot but the weather was very cloudy with low marine cloud. Shot my house instead.

Picture was at 1/45 of a second and f6.7 set on auto mode because of the dim light. First pic with new mount. Hope for sunny weather tomorrow.

Shot at 1/45th of a second!! VERY impressive to be able to get a shot pin sharp at that speed. You've got a great system.

Good luck for tomorrow's weather

Cheers
