    Newb to the hobby and need advice! :D

    Is the seller from North America or from Asia? The reason I ask is that DJI Hobbies/Innovations just released a brand new product called the NAZA Lite (see their web site)...... which is a lower cost item relative to the previous version 1 NAZA..... (neither to be confused with the new NAZA...

    MTBF (Mean Time Between Failure) Poll

    For a better response please look for the forum tool to set up a poll..... I think most members are authorized to do that. The wording of the poll questions must be able to somehow distinguish between a system/setup/configuration issue and a MR controller/IMU/firmware issue otherwise poll...

    Just got started - now seriously building my own airframe!

    One of the great secrets of a super strong structure is to use soft material in the middle and reinforce it with a couple of layers of fiberglass or carbon fiber on the outside. Using quality epoxy as a binder and vacuum bagging one can achieve tremendous structural strength and pine is an...

    Video Downlink specific to IOSD!

    An approved distributor for DJI indicates the following for their 5.8Ghz video downlink system...."The new DJI Downlink is specially designed to work with the new On Screen Display module, and Zenmuse gimbal for professional aerial photography and video" . Does this means...

    Noob setup and questions...Help!

    5.8Ghz question: I am seeing a 5.8 Ghz video downlink system that does not advertise transmitter power output in dBm, i.e., 24 versus milliwatts and a range of 1.2 kilometers. How do I compare this system with another that is advertised with a transmit power of 6 milliwatts? I realize that...

    Motor Speed, efficiency and flight time!

    Some time ago I noticed on this forum that someone had indicated propeller speeds must be kept below 80% of the speed of sound. It reminded me of something I read some time ago on this topic. Today I found that info and thought it would be good to post it here for other who are curious. Turns...

    Newb to the hobby and need advice! :D

    IMHO - Typically one can get by quite well with 2 batteries in parallel to power the MR but rarely will require 3 in parallel. Depending on motor voltage rating I use two 3S or two 4S batteries in parallel, each with a capacity of 5000 mAH for a total of 10,000 mAH which equates to 20 amps for...

    DJI naza howing problems

    Your props appear to be mounted abnormally high above each motor according to photo 1. ISeisomometer for IPhone provides vibration date in 3 dimensions, i.e., x,y,z. While you can almost eliminate the two horizontal vibrations, i.e., x and y..... you cannot eliminate the up/down vibration...

    Are DJI F450/550 "legs" structural?? Camera vibrations after removing two legs!!

    No.... you have not adversely affected the structural integrity of the MR airframe but the center of gravity has been shifted very slightly which should not be an issue. Vibration is an MR killer...... sooner or later you will have an MR fly-away. 1) May I suggest you first focus on...

    Gimbal competition?

    This item seems to indirectly compete, at least in price, with the 2 and 3 axis gimbals we are trying to use for MRs. Weight, wireless interfacing and control override may remain an issue but price looks good. http://www.gigapan.com/cms/shop/epic

    RTH Vs Gimbal Activity - HELP

    Are you trying to share the WKM X2 parameters between gimbal control and remote gain? If so, there are known interference issues. Many have experienced severe bucking of the MR when attempting a RTH after previous use of X2 set for gimbal control. In particular when the gimbal center point is...

    The DJI ARF package requires the 30A Opt ESC red and black leads to be soldered directly to the DJI lower plate/power board. I added the red Super Tiger power connectors to allow for quick connection/disconnection of individual ESCs so that individual motors could be balanced with the iPhone...

    RCTimer 10x38 props and DJI 2212 motors

    The machinists are the experts at this sort of thing. Unless the drill bit is modified it will pull the enlarged hole off from the original center. A pointed tapered reamer enables the fluted end of the stepped reamer to get a start. The other thing to keep in mind is the keep the reamer...
