    Product Review ** DJI 1552 Folding Propeller

    I would like to add my thanks for the hard work and the excellent presentation of your results and conclusions. It is quite helpful to have both objective data and your subjective impressions. Steve

    Recommend a charging station for me!

    Fwiw, last summer, as soon as I saw 6s 5,000 to 10,000 mAh Lipos in my future, I purchased the 4010 Duo and the Junsi 1200W 50A Adjustable Power Supply with PFC. This PS offers high efficiency and is generator friendly for field charging. I've been quite happy, though there have been some...

    CarbonCore Cortex....Owners' Thread

    The possibility of triggering unintended Go Home or Failsafe is certainly something to be mindful of. And perhaps a more sophisticated approach to defining when the FC should *NOT* obey the command is feasible. However, keep in mind that this vulnerability only exists in the moments after the...

    Broken ZM H3-2D (anti-vibration mount) - Looking for sources to replace it!

    1uas.com (aka intelligentUAS.com, formerly RCRUS.com) has been a reliable source of DJI equipment for me over the past year. It appears they currently have the part you're looking for in stock (Part 17 H3-2D mounting plate) for $20. Not sure about internation shipping & etc. though... See...

    S800 EVO Motor Mounts are not installed properly at factory!

    Just in case someone comes across this thread and is left wondering which is "right", here is the text from the 07-Feb-2014 version 1.10 of the s800 EVO User Manual: "Assemble the Vibration Absorber of MotorsThe soft gasket is apart of the Vibration Absorber and it has a thick end and a thin...

    IMPORTANT...What are your favorite forums sites???

    My top to MR website destinations are MRF and RCGroups. RCG is cluttered and sometimes has a lower 'signal to noise' ratio, but the underlying site functionality is good. One feature that would be a nice add for MRF is a longer history for 'Active Threads'. I see no reason why this couldn't be...

    Can manual mode be disabled but made available for compass calibration?

    Hmm interesting suggestion. So you'd have to hold the momentary switch while toggling to trigger compass calibration mode, correct? Steve

    Wookong-M Assistant Software for Mac Released!! v2.04

    The risk will be very low because you're only allowing that app to run, not shutting off the whole app security configuration. Steve

    Buyers Remorse???

    What amazes me is the number of people who just dive right in and start flying MRs without even bothering to read the documentation. I could be wrong, but my sense is that, for better or worse, DJI is selling *way* more than any of its competitors. Further, they're the first with kits that don't...

    DJI Wookong yawing right in Manual but not in GPS or ATTi

    This topic comers up periodically. FWIW, on DJI's s800, s800 EVO, and AFAIK s1000, DJI intentionally tilts the CW motors one way and the CCW motors the other way (using shims or dampers of different thicknesses). As Peter mentions this provides added control for the FC about the yaw axis. The...

    Considering a Phantom 2 for First Multirotor - A Few Specific Questions

    DJI is just a little behind in delivering the necessary new sw and fw to support the Ground Station with the P2. Here's what they posted regarding this situation on their Facebook page on 27-FEB: "iPad Ground Station support for the Phantom 2 is just about ready! We apologise for the long...

    Buyers Remorse???

    Agreed, flyaway reports are distressing! But it's hard to discuss what's common and what isn't. We see the numerators but the denominators (installed user base) are not clear. We all understand that users with problems are over represented on forums. This is true for anything, cars, computers...

    Buyers Remorse???

    I suggest resisting the temptation to draw conclusions based upon single forum posts (including my post, for sure). Most people will never need to go through the hoops indicated (magnet & etc.). The best approach is to look into things ones self. In doing so, you may find Colin Guinn's video...

    Throttle center detent

    The above may be most relevant if you're planning on using DJI FCs. For these, as you stated earlier, the throttle position is really just an input to the FC. It is not directly related to motor RPM. In DJI's algorithm (non-manual mode), throttle position is more like a relative...

    DJI Lightbridge - 2.4G Full HD Digital Video Downlink

    As far as the "piggybacking on an RF system never designed for this (i.e. Futaba)" comment, I don't understand the underlying concern here. *If* I understand to Lightbridge concept, the 'transmitters' are really just out-board controllers they no longer transmit anything. Their RF outputs are...

    DJI A2 Performance/Build Comparisons

    Any idea why recommended battery is '3S' for the 'system' vs. '3S-4S' for the ESCs? If indeed 4S is not a problem, then shouldn't the system be 3S-4S? Steve

    Throttle center detent

    Well this may be generally true with some FCs, but for DJI FCs with recent firmware versions, this is only strictly true when operating them in 'manual' mode. When DJI FCs are in other modes, i.e., Attitude Mode (ATTI) and GPS Attitude Mode (GPS ATTI), then the FC's automated flight control...
