    S900 Owner's Thread and Mini Build Log

    Mine is at 7.45kg with a 10000 lipo. I think that the BMPCC is lighter than the GH4/GH3. I am using the Lightbridge which is heavier than the Rx/vTx combo and I have a FPV cam mounted with a 3Sx1000 lipo to power it.

    The best FC for controlling yaw in a GPS piro was a F450 with Naza V2 on v1.8 of the firmware. It would spin forever on a dime. The later versions have lost that precision but have added many more features that make that loss not as significant. It does not bother me as I can compensate for a...

    I won't be exploring those limits until the new wears off in the next few weeks. Plus I have Phantoms and a 4S F330 for more aggressive flying. :)

    The S1000 is definitely more sedate than the S900. The advantage of the S1000 over the S900 is greater safety if one motor goes out with an octo vs a hex. You will have greater lifting capacity with the S1000. One of the limitations of the size of the S900 is the height of the landing gear...

    Most of it was me. But some was the craft. Slow yaws with a little breeze in GPS, 5-6mph, you will see it. I only had one hand so I could not correct it.

    Andy, I have not removed a mount. My guess is that there a metal sleeves molded into the composite. After the new wears off this weekend, I will open up one of the motor mounts and show some pictures.

    The cell phone video from the ground. I don't do well trying to fly and film at the same time.

    I just finished the first 3 flights on the S900. I flew it with gimbal and camera attached. I was pretty confident in the A2 and the airframe. My first flight was 12 minutes on 10,000mAh. This was way too long. I landed at 21.4v however, when I charged the pack I put back 10,000. On my...

    Benjamin, It feels very solid. The arms actually feel more locked in than the S1000. My guess is that it has to do with the composites vs the aluminum. You actually get some friction between the contact points.

    Electronic are in now time to upgrade all the electronics, set model in 14SG, calibrate in LB Assistant, calibrate in A2 Assistant, set gains (I will be using the same gains as me S1000), take off the gimbal and camera and fly. The manual is now up but is currently only the parts list and...

    A2 FC Firmware 2.3 - Here We ALL go Again

    Thank you for the video. It has been shared but it does not change the interpretation of the data on the flight logs. I understand that you feel differently but your interpretation of what happened is no more valid than ours. Also I do not have a response to your question concerning rolling...

    The machined Al motor mounts and arm mounts versus the Composite items on the S900 are the major difference other than the size and two less motors. I have not noticed any play or looseness in the arms at all. I do not know how they will stand up over time. Here is a 72 hour test video.

    I have to run out but the current weight with 2x6S Turnegy 6000mAh lipos and the BMPCC is 7.27kg. My guess is that with a single lipo and electronics you should be able to get to 7kg including gimbal. I will answer the rest of the questions shortly.

    Build notes: - Inorder to mount the gimbal I had to move the front support bar back 10mm. Even with that it is a tight fit. I would like to see the rails a little longer but that is a quick fix. - To balance the craft I had to move the lipos forward about 60mm. I am going to move the lipo...

    Absolutely! I know that it is important to you guys. tikigod19: I don't think that will be possible. You will have a better idea when I finish the build. The Zen for BMPCC with camera and lens is about 4 pounds. I am pretty sure that the GH4 is heavier.

    The motor mounts are also the same composite. Let me know exactly what you would like to see and I will photograph it.

    This a comparison of the S1000 and S900. The S1000 is 45cm tall vs the S900 at 41cm. The landing gear is 56cm vs 41.5cm. I have not weighed the S900 yet. I still have to install the electronics. I should have that tomorrow. Then time to set up the Lightbridge, the A2 and I am going to...
