Finally my heavy lifter Robbe Eolo is completed. This has a very powerful motor and my plan is to build an AP undercarriage with a tilt function.

What I am asking you guys is the following:

I am considering the Pentax Optio S5i or the Casio Exilim camera. I need the following functions on the camera and am wondering which would be better.

1) Manual focus
2) Video out (to be used with the new Digi-live from Black Widow)
3) IR trigger capability

Can you guys point me to the IR trigger link?

I am looking to do still photography for real estate purposes. With this small and quiet heli, I figure it could really work nicely.

I want to use my iCom IC-R3 receiver to see the camera's downlink feed, anyone know if this can be done with this scanner? That would tidy up the ground support angle nicely.

I really appreciate your input, thanks in advance.

keepin' it real

This one? GentLED

I don't know anything about the cameras you're looking at though. Hopefully someone else does.

I have done some searching, and from what I can see the Pentax Optio 5Si is the best for small helicopters like ours. It supports IR remote controls, weighs 105 grams, and have live video out.

Pentax also have the Optio 5Sz with similar spec, but I dont know if this have live video out. S4 and S40 have 4 mega pixels and can be remote controlled through IR. All these weighs 110-125 grams.

Canon Powershot S70 is 7 mega pixels, supports IR and have live video out but weighs 230 grams.

From what I have found the Casio Exilim does not support IR - but I might be wrong.

Stet.

Congrats on getting your bird setup.

I've read on the forums that the ICOM R3 isn't good at picking up the video signal. I found this via search but have no practical experience either way. If you could, i'd go to a local LA spy store w/scanner and try to pick up a 2.4 feed of one of their transmitters before you by the equipment.

Best of luck in your new endeavor.

Michael.

Stet,

If you haven't bought a camera yet you might consider the S70 over the Optios. Spend some time over in the AP forum on r c groups and you will see the Optio's pictures don't turn out that great, especially with an electric motor running. I think the motor causes wavy pics because of the CMOS or something. I think they are fine when people turn of their motors and glide but if you find a way to do that with a helicopter let me know

I'm carrying an S70 with a T-Rex and 335mm blades which are really 320mm and it does fine, but probably wouldn't survive an auto very well. I just looked at the specs on the Eolo and it says the blades are 385 so depending on gearing, motor, etc you should be okay.

Uuups, I just got myself an optio 5sz

Gentled is in the mail so I'll see if I can get the time to test it out this weekend.

I thought that's what I remembered reading, but it has been a while since I researched them. Hopefully you will prove that to be wrong. Post some pics when you get everything working.

The sole reason to consider the Pentax line of cameras is that they are small light, inexpensive, and take great pictures for the money, most importantly work with the shutter remote made by MX called the "Prism" switch

http://www.hexpertsystems.com

I couldn't speak more highly of this product, and the service and support that i recieve/d with it. Money well spent.

"PRISM plugs into your R/C aircraft receiver, and converts the servo control pulses to the infrared signal protocol necessary to trigger the shutter on your digital camera. Designed for aerial photography applications, PRISM provides a rugged, reliable method for remotely triggering your digital camera. Since PRISM uses the infrared remote port of the camera, there's no need for modifying the camera or using a mechanical servo. PRISM doesn't even need to touch the camera. It works up to several feet away!"

works with:

Pentax Cameras that support the Pentax Remote E or Remote F

Olympus Cameras that support the Olympus RM-1 or RM-2 Remotes

Canon Cameras that support the Canon RC-1 or Canon WL-DC100 Remotes

Nikon Cameras that support the Nikon ML-L3 Remote

around $25.00

Good link Travis

Think Ill grab a few myself.
Might be easier to supply one of these with my mounts instead of patch plugs I have to make up for each user..

Thanks! I appoligize, this is a little off topic, but very worth while.

While you are there, be sure to see the "Zlog" altitude recorder as well.

This is also made by hexpertsystems. This is a small device that plugs into your rx and you can hook your shutter release or "prism switch" to it and or set it on one of many settings to record the altitude that the picture was taken at. You can also simply power it off of your RX and use it to display current or max alt.

Here are some of the details, you can also download your flight info post flight. I hear that V2 is about to come out, it is smaller and more memory. Rumor is that the maker is working on a model that will have or will be compatible with a "video overlay" so that you can get real time alt. info over your downlink.

"Key Features:
Onboard display shows altitude information in real-time.
Tracks maximum altitude - find out how high your aircraft flew!
Display and record altitude in feet or meters.
Altitude resolution of 1 foot/meter.
Record altitude data for later review.
Configurable data recording rate as fasta as 10 samples per second.
PC Interface for configuration and data download, plot, and analysis.
Onboard controls allow configuration in the field.
Include PC software.
Marks altitude data when triggered from an external signal.
Exports data in Excel .csv format or as GIF, bitmap or JPEG images.
Accepts wide range of input power: 4 - 15 volts. Power from your aircraft receiver.
Firmware upgradeable.
Only 0.28 ounces (8 grams).
1.57" x 0.92" x 0.37" (40 mm x 23.4 mm x 9.4 mm)."

I believe that there is a "waiting list" for the new version, the other can be ordered on the site. Please see this thread:
http://www.rcgroups.com/forums/show...highlight=zlog+
(and then come right back to RR as this is mostly fixed wings stuff )

P.S an email, or PM expressing interest in the video overlay proposal might help expedite or guage the market value of such a device.

I like this device because it works in feet or meters, and you can zero it on location or have it simply display max alt. if you don't want to bother downloading the info. I love the simplicity, and performance of the little gadget. Warning don't look at it or you will want one!

A "real time" overlay would be very useful for those balcony shots, that we hear so much about.......as well as to confirm that we are staying within our altitude restrictions.
Please resist the urge to post data showing how high you flew (above the safe and legal limitations) as it only takes one mishap or lapse in judgement to spoil a good thing.

Too late, I ordered a few of each to try out.

Might be in for a regular volume of each.

ZLOG looks great.
Getting questions from users and their clients onsite on how they establish height, currently by counting pole sections raised.
I can see it is going to take them a while to remember how.

The ZLOG should solve that showing shooting height on screen so their clients can see for themselves, and can be documented if they want to save any disputes later on correct height.

I am aware of one who is doing a future balcony shot next week, good opportunity to show them the benefits of adding ZLOG to the gear.

Ill mail the guy.
If I can sell both to my client and it works as we hoped Ill make it standard equipment and buy a volume of each periodically.
Sold them on the PRISM so I hope he has a few of them on hand.

Cheers

Post some pics when you get everything working.
I finally got to test out the Optio this weekend. It gets dark before 6pm here so the pictures didnt turn out very sharp (just used the landscape mode of the camera). I am not sure how interference from ESC/motor would turn up in the pictures, but I dont think the Optio have any issues with it.

The weight savings I got from changing my old dig cam with servo clicker to the optio with gentled made a huge difference in flying. Now it is very smooth and easy going - no problems navigating around my tight back yard.

Lorent's,

Those do look good for the light you had, and the colors are bright. It's not doing what I saw in the other forum, there was a definite wave in the pictures, and it was so long ago that could have been another camera.

The gentled makes a big difference, alot better than a servo. The only issue is the gentled didn't work 100% of the time in the sun so I put electrical tape over it to the camera.

Glad you got it going.
