Yes it really actually pans.. It is capable of panning 360 degrees but is presently setup to only do about 180..90 degrees left to 90 degrees right..

For such a simple function it took a lot of work really... I started modifying a servo to do continuous rotation with reverse, then added a variable resistor to slow it down...

The ping pong ball was cut in half...and one half drilled out for the lens and sanded. Then two halves cut for the boom to go inside.

The cam was mounted inside half the ball and fixed with some silicone..
Then the two halves joined with CA.. Cam wiring into the boom, not yet affixed.

The ball then mounted on the aluminum alloy boom, sealed and a small epoxy pour to hold it in place..

Outside of ball sanded smooth..

Made a bearing using a soda cap, epoxy and aluminum skin from old antenna.
Sizing and fitting done before hand.

Bearing epoxied into wing..

Servo mounted under bearing and fits into a servo arm end which was epoxied into bottom of boom..

The servo going directly into bottom of boom.

Servo controlled via 3 position switch on radio, left, stop, right.

Key cam is mounted on top of ball which has a hat on top, another shorter bottle cap epoxied on..providing a flat surface for the mount.. Tether used in case of mount failure.

Entire plane can be picked up and carried by the ball but it's not recommended... lol

Body work done to hide the scars..

If you need more info just ask..

I'll shoot a vid of the cam moving at some point soon..

Wow thats well thought out! What did you need to do to make the servo continuously rotate?
What TINY cam did you use?
Thanks!

Thanks,

Well most servos want to continuously rotate except for the fact that there is a potentiometer that reports the position to the electronics and then there are normally little plastic stops that prevent the output shaft from turning past a certain point...

It was a while ago I did this so I may be a little fuzzy.. But I found a short cut over the methods I have seen online.. This involved simply using CA to lock the potentiometer at exactly the middle position according to the Rx.. So IOW you plug the servo in and get it centered... Then CA the pot to make it stay there...(a drop right on the mechanism seems to do the trick.) Then remove the stops that prevent turning... At first it will be tight because the pot is not turning however on my servos I found that with a little help while it is apart turning the shaft with a wheel by hand loosens it up so it turns freely although the pot does not move.. You have to be certain that: The pot is centered and cannot move and that you get no CA near anything else, then allow the CA to totally set before moving servo around. Then finally remove, file off the stops.

This cam is old now although still well regarded.. It's this one, in 12volt, but they make them even smaller these days...

Guys,

Going to take out my STOCK Cessna 182 out for some more action at the Maiden Site with the large Concrete High School Band Practice surface! I will see about someone to record my Flight using my High Definition Digital Camera.

Happy landings!
Carlos

Thanks, a buddy took the photos for me.

The Cessna is covered with Oracal vinyl and Callie Graphics decals.

I'm having trouble putting the wings on. The screw hole in one wing doesn't line up with the screw hole in the fuselage. Anyone else have this problem? How did you overcome it?

Some pics would help..

Which holes are not even, on the wings or on the fuse?

Generally the wings must be joined and then popped into the holes in front and pushed as far forward as possible.

Yes, I had this problem and reported it a flew pages back.

What I did was to carefully hold the wing assembly halves together "while" holding the complete wing assembly down and applying pressure into the fuse holder.

You pretty much need another pair of hands.
