    S-1000 wont start

    Not being familiar with the S-1000 FC, but is it possible the throttle gimbal needs calibrated to the controller? Alternatively, might the end point adjustments of the throttle channel be above minimum acceptable on the low end of the throttle range? Lastly, might the channel be reversed in...

    DJI A2 Failure Videos

    Congratulations!! After someone else took a look at mine tonight the decision was made to abandon it for a Wookong. I guess there were 3 sitting in a shop in Portland they were having trouble selling. That will get this ship up in the air while I start on another project with a Super-X...

    DJI A2 Failure Videos

    I'd like to respond to that from several perspectives. First, you are absolutely correct regarding the WooKong and the 5.16 software. It works, it has worked, and those that have had problems after that release did so simply because they upgraded without first reading the software notes...

    DJI A2 Failure Videos

    Indeed, and is the reason why DJI will receive no further consideration with any of their products. Considering that applies to a continuing build of a great many multi copters their financial loss is significant.

    The condition is not exclusive to multirotor products. I can understand where you're coming from though.

    A2 at sea on this research yacht

    I am neither an optimist or a pessimist but having experience with sUAS launched and recovered from vessels I strongly suggest that any kind of high power radar be disabled anywhere the aircraft is intended to be flying. Absolutely shut it down for launch and recovery. Recognize your return to...

    DJI A2 Failure Videos

    After experiencing close to 20 years of product design issues with various hobby products from the eastern manufacturers, I'm sorry to say you have little to no chance of getting crash losses replaced unless the vendor that sold you the A2 does so out of the kindness of their heart and the cash...

    A2 compass and GPS calibration, and other issues

    That was tactfully done Ed:) That was helpful in establishing the calibration sequence is done pretty much the same was as with a Naza. I failed to mentioned I've worked with the Naza before on a Cinestar and done compass calibrations with that one without issue. The same over rotation...

    A2 compass and GPS calibration, and other issues

    I definitely can appreciate what you're saying. I have almost $2,500.00 in the frame (custom 1200) alone. By the time you toss in some large pancake motors, ESC's, big batteries, and some 28" props into the mix you're looking back over your shoulder to see where $8k+ went. To get into the air...

    A2 compass and GPS calibration, and other issues

    Need some idea folks. Against my my gut feelings I went ahead and upgraded to 2.3. Things are now worse than they were before. See the screen shots. The connection error message absolutely HAS to be in error. The manual references are precisely matched to the component installation. OTH, I...

    A2 led flashing white with motors unarmed

    Here's what I get with 2.3. Then again, I've suspected I have a trash IMU from the beginning.

    A2 2.2 Upgrade Guinea Pig

    As one that has been flying RC for well over 40 years and also a commercial pilot/flight instructor I get to experience both sides of this issue, and it's a doozy. An attitude much too prevalent in RC, and even more so with FPV and aerial photo folks is they have a right to do anything they...

    DJI A2 Failure Videos

    A rash of software fix releases is a very bad sign of someone that is churning out untested code and playing catch up after the fact. FWIW, I have an A2 that refuses to calibrate compass and GPS so it hasn't flown yet. That may be a good thing.....

    DJI and possible EMI susceptibility

    Has anyone investigated how susceptible DJI controllers (or any other) are to EMI, or electro magnetic interference? I wonder about this when thinking about the power distribution boards we use to power our systems. Many of the larger multicopters use a centrally located power distribution...

    A2 2.2 Upgrade Guinea Pig

    I have not tried the Pixhawk yet and my experience with the APM-Arducopter system is limited to only one machine but my opinion of that system to date is quite favorable. I have yet to hear overwhelmingly great things yet about them from the large multicopter users but those flying medium and...

    A2 2.2 Upgrade Guinea Pig

    I spoke with X-Aircraft yesterday. I have a very large quad getting set up and after exchanging some info to get the him up to speed on what the controller needed to do he said something I have never heard before from any hobby vendor. If I bought it and sent some pictures of the rig to him...

    Pixhawk the new flight controller from 3DR

    Thanks for the informative reply! The linear regulator info was quite interesting. Leaving the large copter out of this part of discussion, I also fly one of the discontinued 3DR quads with Ardupilot. Thinking about your comments on natural stability took me to something I did in error the...
