    Just goes to prove it is the photographer and not the camera.

    Sony NEX-5

    Were you there when I opened the show with a PZL Wilga towing a banner VULCAN TO THE SKY - BUY A TEE SHIRT. One of the Utterly Butterly Stearmans came at me in the opposite direction and made a barrel roll around me and the banner with a girl on the wing. Totally unrehearsed. Forget the...

    Sony NEX-5

    Unless you are a producer then you don't get to see official show reals but I used the Gyron on a pop video for a great singer from Russia named Zara you may be able to find it on utube. As for Cineflex it is almost impossible to shoot unsteady footage. Suffice to say that after 12 GP's 2 RIAT's...

    Sony NEX-5

    The 5D does not deliver unsharp images if used correctly. Most amateur photographers think that using a fast lens at full bore will give the best results due to faster shutter speeds. Just about all lenses deliver the best performance at around F8 / F11 therefore you should aim for that and...

    Strange pulsing of power.

    Tabb I think you will find it is a ESC timing problem.

    Sony NEX-5

    Having used both Gyron and Cineflex quite extensively over the years I can say without doubt that Cineflex is a much more highly developed smaller lighter and accurate. You dont find many Gyron FS on the front of an Apache. military funding will win in the end. Last time I used a Gyron was with...

    Sony NEX-5

    On stills no but on video it is remarkable. Full frame has only one use in broadcast TV that is depth of field control. The opposite requirement for aerial imaging. Canon in their own admission say that image quality from 7D/550D is more practical. The worlds best aerial video system is the...

    Sony NEX-5

    FWIW I have found the video quality of the Panasonic HDC-TM 900 to be better than the 5D and it is a huge weight/cost saving but it is sensitive to vibration. If you know how to deal with that then it is a better choice. I often expand mine to 2K. For the average enthusiast who just wants to get...

    motors at idle

    That never happens with mine Dave. Naza or M. So I guess you need to redo the ESC prog. and recalibrate the Tx.if that doesn't work swop them around and see what happens. Could also be the compass calibration. make sure it's level when you turn it on.

    Camera Stabilization.

    Jess have you not seen a HKS-HV787P. Even if it did have any backlash I think a man of your capability could solve that issue with a spring?

    Camera Stabilization.

    I think solidworks is a great way to create some ideas for camera mount designs. What I have done with this latest creation is to have a different mount for each of my cameras. GoPro, Panasonic DMC TZ10 and Nex have a different style to the one for the 550D and the Pannasonic HDC-TM900 and...

    Folding Vtail Quad - new build

    I recon that the next step might be to increase the size of the side lifters and decrease the rear ones to give it more efficiency at the CoG. Steers beautifully as is though. Could be the next big trend in camera ships. My problem is trying to stay out of the sun!!!

    Not off to a good start in the new year...

    I would be very careful using dunked ESC's, they could have corrupted firmware during the dunk/short. Give em a good test over time on the bench first.

    Camera Stabilization.

    The Full Scale Range of my IMU gyros and the accels. sensitivity is a trade secret but it is significantly more sensitive than the typical 500 deg/sec used in most FC. imu's. You can with a little patience get quite good result with a CC board. About the same as a Naza.

    Camera Stabilization.

    jffry7 I'll try to keep you informed as thing progress. It does have some quite unique ways to get the job done. Hand built unfortunately but a lot less expensive than a big OKTO. Having seen the problems that some have had by releasing stuff before it is full tested and 100% reliable it wont be...

    Folding Vtail Quad - new build

    Mat I think that is excellent, Has a lot of potential for a front view camera platform. Is that a CC custom algorithm or your own. I love to see innovation.

    1001copters.com [benchmark] motor and propeller test

    Cedric Really please to see your dedication to this aspect of research. When I have some spare ones available I'll send you a REAL prop. to try. This kind of blade can only be replicated in autoclaved carbon. Wet layup is far too heavy and does not have enough torsional rigidity. 11x4 12-14...

    Probably the most critical part has been missed here, and that is the weight of the prop. Model stability is linked to the response time of the thrust demand. It has been proved beyond any doubt that the prop.s that give the best lift efficiency do not produce the best stability. Props. such as...
