I bought a helicam solutions mount here about a month ago. Came with the camera and the video downlink stuff. Well last night I was reworking the power from my gassers. I got a raw generator output lead down to the bottom of the heli frames (1005 and Spectra-g).

On the mount itself, I removed the 4 cell NiCD battery pack and the 3 cell Lipo pack that runs the video. I replaced them with a electronic switch that runs off the gear channel, and a 5.4v regulator from my Jewel parts. I'm short a 12v regulator which I've got on order.

What's going to happen is that the heli on-board pack will backfeed through the lines and run the camera mount receiver leaving the electronic switch off. I'll start the engine and the Jewel will start supplying power to the mount. The 5.4v regulator will limit the voltage to the receiver. As I spool up, the jewel will be providing more and more power, and soon enough before liftoff I should have 12v+ available to me. I can wait until after takeoff at which point depending on rotor rpms I should have 13.5 to 17.5v coming from the generator and that will be regulated to 12v for the video transmitter. I'll hit the gear switch on the camera TX and the power will be turned on electronically to the video transmitter. This way the whole mount will run with no batteries, just on the generator itself. And, with the electronic switch for the video system, it solves the issue of having the system brown out before takeoff and on landing.

I'm excited to try it out. Maybe even as soon as this weekend depending on weather and such. The TX for the camera mount is setup so that throttle down all the way turns the camera on or off. Throttle up to 3/4 focuses the camera. Throttle up to 100% takes a picture. Right rudder is zoom in, left rudder is zoom out. Left/right aileron is pan left and right on camera, and up/down elevator is tilt up and down on the camera. Gear switch is video downlink transmitter on/off, and dual rate switch is slow/fast pan/tilt speed. Sounds like the perfect setup, I'm ready to try it out!

Thanks guys!
I'm afraid this is a whole new time sinker as well as everything else! Between the day job, the flying for fun, Jewel stuff, email support/runryder posts and now this, will I ever have enough time for everything!?!?!??!

I think I need to quit my day job

Question John
I noticed last night that the camera mount was front heavy (of-course with camera and no batteries to balance) and if I put it on the heli facing forward then the heli is nose heavy. However if I mount it rearwards (camera looking behind) then its OK CG wise on the heli but the rear 1005 muffler is blowing right down on the camera. I know there isn't alot of oil in gassers, but have you done this and do you find it to be OK?

Hey Raja, here is a pic of my mount, I know its not like yours, but maybe it will help..

I balance mine just like you do your heli by itself, You might have to move your heli more to the back of your mount, You will want to get some noodles for your skids, and make sure you don't pull your bungee's to tight when you hook the mount to the heli,, You will want it to kinda hang from the heli, not to much, but not to tight either,, Hope this makes sence,, Good luck,, your going to love flying AP,,,

Also, is there a way to move your gimble back more?? that might help in balanceing the whole setup.. XGM/VGM

I love the airborne picture
That is SOOOOOO Sweet!

I think your camera mount is better designed with the payload of the camera directly below the main shaft. Mine is up front or to the rear whichever way I mount it. But I don't think the CG will be that big of an issue, its not like I'm doing 3D with the thing so worst case scenario I'll dial in some back trim...

I am looking for something similar but with a lot more amps. I am thinking 10-15. I anticipate having to use a small nicad pack and hope that will take out the ripple that may occur in the video from the generator.

It is a shame, I took on another job besides my day job and I haven’t been able to do a damn thing with my heli projects.
However if I mount it rearwards (camera looking behind) then its OK CG wise on the heli but the rear 1005 muffler is blowing right down on the camera.
The heat waves may distort your image if nothing else.

Yea, Worst case senrio, would be to dial in some back trim,, Have you had it all together yet? Heli,mount, with all gear?? and tried to CG it?? I think your gimble can be moved back, but if you do it might get the mount legs in the pic's,, Lets see some pic's of HER all Dressed up for a night on the town XGM/VGM

Well I got excited
Got home and strapped the 1005 gasser to the top of the camera mount. Fired it up in the back yard and the camera moved ok on the Jewel generator power. For now the video downlink was running on a puffed lipo battery that I got with the mount.

Anyway I took off and hovered, and with the camera mounted frontwards I noticed I needed about 5 clicks back elevator trim to hold it level. I landed again and tapped loudly on the kitchen window and signaled the wife to come outside and take some pictures.

Took off again, climbed to about 100 feet and held a hover while she fiddled with the controls and tried to take pictures. She had a hard time centering the house but I think it was a factor of not knowing how to work a TX and move the camera in the direction she wanted. It was quite windy after a snow storm and rather cold and getting dark, so after she fired off about 5 pictures (I could see the flash) I came back and landing the thing and ran inside to rewarm my hands before coming back to de-gas it and take it back in the house.

Being overcast and early evening it was getting pretty dark so the pictures are quite dark. I haven't downloaded them from the camera yet to see how well they look but will do that next.

Anyway, had my first dusk photo shoot tonight!

Just looking at them now...
They pictures are rather dark, guess it was real late last daylight minute flight and even though they seem dark its hard to tell but they do seem to be in pretty good focus. There is some white specs that seem to reflect from the flash and my only guess is they they are snow flakes or fine percipitation?

Now all I need is GPS autopilot hover so I can take my own pictures!

One thing that might help your wife, Is if you set it up alittle differant,,
ailerons= roll (which I don't think you have?)
elevator= up and down for camera
throttle= low stick, zoom back, mid stick, hold, full throttle,zoom in
rudder=pan
any switch=take pic
This is how I have mine set up for my wife,, She also has a Transmitter tray with monitor attached, so she can stand anywhere I go,

Could you put the power on and off on a switch instead of the throttle?
I just turn my camera on before I take off, That way the wife can see that everything is working,
Just something you might want to look at,,, Again Congrats,, XGM/VGM

I thought about it
But the trouble is I think is that you want zoom on a spring loaded stick and that is why I put it on the rudder. This way when you are zooming and let go, it will stay at that point as the stick auto centers back. Otherwise you'll be pulling forward and back on that throttle stick to get the zoom to go in and out and stop at center stick.

I don't have roll so the right stick is taken up nicely with left/right and up/down on the camera.

I did make the "throttle cut" button the button to push to turn on and turn off the camera. This way if you throttle back all the way nothing happens, you have to push the "cut" button to turn off the camera instead.

With 3/4 stick being "focus" when you move into that range its like holding the shutter button half way on the camera and it focuses, full throttle snaps the picture.

I suppose I could move the picture taking button to the idle up switch or something of the sort, but then I lose the "focus" capability (3/4 throttle stick). The radio I have for the camera is a basic 6 channel Futaba heli radio, so it doesn't have many switches and no knobs.

Probably with some experience she'll get it. But I want to try it so I need a good heli pilot I trust my ship with to take it up for me to play with the camera controls....

This is really awesome stuff, glad I got my mount as I always dreamed about doing this! I think on the next good day I'll be taking some panaromic pictures of my neighborhood. I'm sure the neighbors are going to start asking questions...how did you deal with that???!?!

You will always have onlookers if flying in a neighborhood, Just be sure your safe, and have a bale-out plan, just in case something does go wrong, Most people are really excitied to see it fly, Not something you see it the air everyday,,

Just a heads up,, there will be some that will jump on the ban wagon about safty,, Just use good judgement, as I know you will,, Again, Congrats, Welcome to the wonderfull world of AP,,
Now you will have to start posting in the AP thread, where are you ever going to find the time,, XGM/VGM

Leme! Leme!

Just kidding Raja I know I am not good enough. But all kidding aside if you are going to do AP you should get a stabilizer no matter who flies it for you. Then your wife could do it! Wait a minute, if she smashes it up she will have to buy you a new bird. Win, win, think about it.

Just as an idea, you can make any stick into self centering stick by using dental damn material and fixing a collar onto the stem. You have to find a way of attaching the sheet to the case of the transmitter. This might be the hardest task if you don’t want to dedicate the transmitter. Dental damn (a thin sheet of silicon rubber) will center the stick in both directions, not just one direction. If you are only interested in one direction then cut the sheet into a strip. Not as narrow as a rubber band but narrow enough that it doesn’t have any side force in the other direction.

I got pictures!
And I'm drooling over them now!!!!

Flew around the house back side then front side and the Mrs. shot away the whole 128mb card. Will sort through them to pick out the best ones and then I'm emailing them to my friends. If you want to see them shoot me your email and I'll put you on copy.

YEAH baby!
