    Interested in Learning to operate RC Helicams?

    in General Discussion

    Posted

    Hi, Guys

     

     

    If you are interested in learning to up you production value, RC helicam is the tool that can do just that. Problem is that they are very challenging for people who are not incline with operating Radio control crafts.

     

    We have created the first all dedicated aerial photography forum, www.APGeeks.com for people interested in the craft. It's a friendly environment for anyone to learn and ask question. You won't get hostile response from other experience members that many of these one subcategory AP forum will experience.

     

     

    We have both beginner and pro pilot section, so you won't tick off other members. Check it out and your questions will be answered.

    Current Rig are setup for Canon SLRs. We have ones that can carry 6 lb cameras comfortably and have carried up to 9lb setups such as the SI 2K on link below.

     

     

    Have never carry a HD link before, if camera and HD link weight less than 9Lb range, than that's fine.

     

    Depends on the flight patterns required. Flying along people and keep some distance then that's fine. If flying over people if require, then have to fly with our Multicopter that's much safer than Helicams with a HD hero camera and use the remaining payload for the HD transmitter.

     

    How much does the HD transmitter weight?

    Beautiful work.

    What's the biggest camera/lens package your rig can carry?

    And also, can it do a live HD link?

    I was thinking of Super Bowl type applications, or would that be too much of a safety issue?

    That is great. Wow, Red on the quadCopter.

     

    Here is my design of All In One HeliCam, AeriCam.

    Hello,

    I have rc quadrotor which can carry RED one. You can see some shots . There is long time with level horizont. No stabilization software used - raw material from the camera. The wind is 4-5 m/s

    Promising, but to be brutally honest, it lacks precision. This is probably somewhat inevitable with a small remotely controlled platform like a helicopter, but the biggest issue I see is the constant loss of a level horizon. This could to an extent be corrected in post, at some cost in resolution, but I think you will need to do something about this before it can become a really mainstream tool.

     

    My impression was that when the camera is looking directly ahead, all is well, but if you're looking sideways and the aircraft pitches its nose down to gain speed (since it's a helicopter, albeit a small one) you end up with a pretty severe loss of horizon. I don't know what you're using for a pan and tilt mount, but I would suggest that you might need to look into some sort of solution for holding the camera level. This could be manually-controlled, or as simple as a gyroscope mounted on a free-swivelling roll axis cage, or as complicated (but lighter) as a tiny reference gyro slaved to a servoactuated roll axis. I presume these things exist, but perhaps not at the scale and weight you can deal with.

     

    Otherwise not bad - the most common plaint I've had about radio-control camera platforms is repeatability, and I'd be interested to see you fly the same shot several times. It needs to be able to hit its marks.

    I am actually in San Francisco for another week visiting. And I bought my still photo Helicopter, I might just go down to the piers and try that shot. Will post it if I got the shot.

    Here is a recreation of the famous earthquake shot. I didn't shoot the shot at the same angle as it's a very busy ferry port. I shot it about 2 blocks off center from the original location. Here is a link to the

    have you ever checked out the draganfly? i wish they offered more camera options but it looks pretty sweet. also, i've done some FAA research, and last I checked, it is technically illegal for non-gov entities/people to use RC for commercial purposes. there has been a lot of talk about a new special regulatory scheme for RC/UAV, but I haven't seen anything on its progress. I think the reality is that the law isn't being enforced at all.

     

     

     

     

     

    Dranganfly carry some where around 1 to 2 lb payload. My helicopter carries up to 10 plus lb payload.

    Problem with focus on Nikon-modified Eyemo

    Hi, Guys

     

     

    I am currently looking to buy an eyemo 71 type camera. Since there's so many models made, which one should I look for if, I want lightest weight eyemo that can fit a Nikon lens?

     

    Is an adopter needed for the nikon lens? And where can I buy one? Sorry for so many questions, Thank you.

    Thanks so much. That's the one I remembered seeing.

    Hi,

     

    All these video were shot by just me, When there's a second camera operator, who can operate the roll will to keep horizon more level. There's also a new item IMU on the horizon, it's available, but I will just wait a bit long for them to fix a few bugs. The IMU will keep perfect Horizon even flying solo without a camera operator.

    Guys,

     

    Sorry, I didn't know so many comments, I guess I have to play with the setting, so I know when someone leave me comments. Yes, the copters are quite difficult to fly, I have been learning for 3 year prior to strapping a camera on it. You really have to master your flying skills before thinking about aerial photography, otherwise you are sure to crash your nice cams. You also need to know the ins and outs of your copter to be able to tune the heli vibe free, steep learning curve for sure, still feel like I know so little. The past year and a half is just learning ways to subdue the vibes. Will have more videos soon.
