    hi Graham.
    have to agree with u
    actually till now i am still not sure what is the correct sequence of events to sw on and hook up to PC, and what is the reverse proc when u want to unplug it all from PC.
    But so far the procedure i have followed has not burnt anything...
    my real worry is always that an incorrect proc might bugger up a Radian permanently
    This is MY SEQUENCE... Andy will have to correct me if i am wrong
    For Programming a Radian (done one at a time)
    Plug in the usb adapter to Radian
    Power up the Radian with a 5V supply to any pin 1 to 4
    Plug in the usb adapter to PC
    Activate the software on PC.
    Now for disconnecting
    Close the software on PC
    Unplug the usb adapter from PC
    remove 5V power to Radian
    Remove usb adapter from Radain
    MY problem is that having a background of fighter aircraft
    everything is laid down in the manual and one has to word to word, leaving nothing to imagine literally.
    Unfortunately in the videos for programming
    this very vital aspect is left out
    I went through the videos several times.
    but was no help in this regard
    The videos show the Radians already hooked up to a PC
    it does not actuall show when to power up and when to hook up a Radain to a PCfor the first and then how to go to the next
    Also
    when wanting to make changes to Radians for Limits and Gains
    the video does not show at all that the gains etc should be done by plugging USB adapter to a particular Radian
    make changes and then plug into next Radian, is it ok to leave system powered on and also radio on all the while.
    NOW I NEED TO KNOW
    WHEN PLUGGING USB ADAPTER TO A RADIAN TO MAKE CHANGES FOR GAIN ETC
    CAN WE LEAVE THE WHOLE SYSTEM POWERED UP
    AND PUG IN/OUT THE USB ADAPTER TO THE RADIAN TO WHICH CHANGES IN GAINS ETC R TO BE MADE.
    I ask this with the same worry
    dont want to screw up a Radian that is worth $350
    the fear is from the aspect that when ever one needs to unplug a usb device like a usb memory stick, etc .. one has to first select eject cause there is a warning that unless u eject the device with the software selection. the memory of usb memory stick could be ruined permanently.
    So i guess for some of us
    there r still lot of mysteries to be uncovered
    In fact in the Wookong M manual which is fairly comprehensive,
    i found a contradiction
    in one locations it says - plug in the WKM to PC usb, and then power up and then activate software.
    and on another page it says to - power up the WKM and then hook up to PC and then activate software.
    Put on issue is does say clearly that - close the software first and then unplug the usb from WKM.
    I have somehow followed
    power up the Radio Tx
    power up the WKM
    plug to PC via usb
    activate programme
    and once evey thing is done
    close programme
    unplug usb
    and the multicopter is ready for lift off.
    i AM HOPING ONE DAY THAT I WRITE SOME MORE PAGES TO THE RADIAN MANUAL AND SEND TO THE RADIAN GUYS.
    My apologies to one an all for such a longggggggggggg comment.
    so i will desist from adding any more lines to this comment hahahaha... really sorry guys....
    regards

    Ramesh: I leave everything powered up but find that I often have to click Connect may be 10 times at one second intervals before it will connect after I've moved the USB cable over to the new servo.

    You'll not do any damage if you move the Radian's USB cable from one Radian sensor to another while the USB connector is connected to the Radian USB adapter board and the Radians are powered up.
    The worst that will happen is that you might not be able to get a connection.

    With all of the above in mind, I have found situations where I have to power off the gimbal, disconnect the USB connector from the computer, then either (a) power up the gimbal and plug the USB cable into the computer or (b) do it the other way around.

    thanks a ton buddy...
    that clarification certainly puts my heart and mind at rest
    it is something that has always worried me.
    Now i can be a lot more aggressive in making changes to Radian settings and gains.
    u have certainly cleared a lot of mystery that i have found around handling Radians
    Thanks buddy
    u God sent dude

    I'd recommend being gentle and affirmative than aggressive! :) You can still bend pins on a Radian. AMHIK.
    Glad to be of help.

    Will this trick also work with my setup?

    Graupner MX-20 for the 3 Radian's (PPM) second operator
    Jeti DC-16 for the octo with an extra Jeti Rsat2 satellite (with Spektrum plug) on the Radian's single operator.

    I have the option to setup the Jeti to double-path (2 way HF)

    To which trick are you referring Mario? (Sorry if I'm being dense.)

    Oh. You mean this one:

    1. You can connect a spektrum satellite and sbus/ppm receiver simultaneously to the radian.

    The Spektrum data is used over the others - so if your single operator radio comes in on SBUS or PPM and the second operator comes in on Spektrum then it will work as single-operator until you turn on the Spektrum when it becomes dual operator.

    The Radian even swaps around the PPM/SBUS/Spektrum channels so they will match as you go between them. For example, the aileron stick is the same selection numder for slew even though the radios are different (well, at least with the receivers I tried).

    The 'Input Channel Monitor' will show you what is going on as you switch between operators.
    Sorry, I don't know the answer. I suspect the only way to find out will be to try it....anybody else know?
    Andy.

    super day today
    did a test run of Hex Copter with cam mount and Radians
    Simply super results
    showed the video to a pro guy
    his remark was that video totally usable after some work on stabelisation by software
    Actually in this particular test flight i had removed the CineStar dampers which have those six O rings in each.
    cause i found tooo much of shake on cam mount,,,, was disappointed....video had a lot of shake, and i could see with my eyes the cam mount shaking
    So then hard mounted the cam mount to multi copter body,
    and put some dampers between cam body and cam mount
    the guy said i had achieved 70% damping, and though video usable after software stabelisation...
    i should try to achieve 90% mechanical damping.
    There was no jelloing cause of the silicone dampers between cam and cam mount
    So why the shake with CineStar dampers
    i would have thought that at $75 a piece, and using 3 on hex,,, it would have been awesome
    And
    i know i do have to place dampers between cam mount and Hex Body
    So i guess i would need to get out of this thread on Radians and move to Hex copter thread
    But Andy.. all thanks to u for all the inputs
    Will always remember u as the Radian guy
    Happy landings
    Of course will always come to this thread daily to see whats up,
    and there is always something to learn more and more
    Ramesh Tahlan
    Salute to Andy

    Ramesh from your description of vibration you should check prop balancing, prop alignment and perhaps motor balance, gimbal balance and copter CG. You shouldn't see that amount of vibration and the dampers should make it better not worse.

    Gary.
    thanks for all the inputs
    looks like a lot of work cut out for me in coming days
    i had checked the copter CG, looked good.
    I had done the Gimbal balance
    also did prop balance
    Now it looks like i need to go through the other items u mention
    and also recheck what i have already done once more to be sure.
    head ache work... but un avoidable i guess...
    cause i have seen some videos put up by this system
    and they look awesome
    i guess the videos were all raw and not software stabelised.
    Ok then
    will start on it one by one
    if it has to be done,,, then it has to be done
    Gary
    thanks for the inputs
    learning process never ends

    wish one of u guys would design a vibration meter or something
    which one could touch to each arm of copter or each motor one by one and check which arm is the culprit
    and start working on it,
    i am sure one day it will be a reality
    happy landings
    and happy hunting for me to find the vibrating culprit
    presently i have 70% achievement in mechanical damping and wont rest till i hit 90%

    Ramesh search the forum for the word 'vibration'. Many of us are using an iPhone app called VIBRATION. Does exactly what you are describing.

    Ramesh you'd be surprised in the short time that forum has been running the amount of data, tools, ideas are in the various threads. A lot of the posters have the 'been there, done that' shirts and have shared the good bad and ugly. While it takes some time, makes for good reading in the evening to start at the top and read through all of the postings. And when you get them all read it flashes a message "You have reached the end of the INTERNET".

    Thanks guys.
    have been figuring how to down load the vibration software to my i4 phone
    when i search for it on my i4 App Store
    it comes up with nothing
    so i guess i will have to down load on my PC first and then upload to my i4
