    New DJI Ronin Gimbal 16lb capacity

    I see that use on MRs hasn't been designed in specifically which is an odd move I think. I'm sure mounting it to an MR wont be too much of a problem but no slip rings like the Zens ie things like Lightbridge wont be very useable with this on an MR

    what is your preferred mixer type for flat octo?

    Whilst the theory sounds good I doubt very much that there is any noticeable flying difference. I fly both a cinestar (I) and Skyjib (v) and cannot notice any difference at all. The v arms I find better for orientation as I can have 2 booms covered in day glow tape Sent from my iPhone using...

    dji a2 two purple flashes

    Well, can you post your gains so that we can have a look- it still sounds like a gain issue of some sorts.

    Unfortunate event as Triathlete sustains head injuries from drone

    Looks like they are trying to hide behind the chap who can use the AR Drone to hack into wifi and other AR Drones. He does that by attacking the Wifi network and protocols involved as I understand it thus for someone to hack into the system here is probably a bit far fetched. Interference maybe...

    How to choose motors for a quadcopter

    Not really as each rig is different with differing needs and each motor and each prop is different ie Tiger motors differ from KDE etc. you need to look at you max take off weight and then work out how much thrust you require and then find a suitable prop and then a suitable motor of which there...

    Who adds capacitors to their power train

    So if reasonable wires, on either side isn't an issue, why is that some of the top ESC makers all recommend keeping the battery to ESC cable under a certain length? Companies such as Kontronik (the best of the lot imo), Castle, Jeti etc? These guys use designers who really know their stuff and...

    How to choose motors for a quadcopter

    g/w is grams per watt of a motor and relates to its efficiency not its lifting power. There are various ways to choose motors and ecalc is well used by many. Another option is to look at the motor's manufacturer's data. For example, T-motor provide charts for each of their motors which shows how...

    When to land?

    Always worth having some form of flight time/voltage alarm as it is sooo easy to get distracted at just the wrong time and next thing you know, your pride and joy has taken a nice dirt nap. Either use a timer, a voltage alarm or a capacity alarm.

    This looks like your gains are perhaps too low. Can you post your gains please.

    First UK conviction for illegal use of an unmanned aircraft by the CAA.

    Nice one Flubbs! The more people we have the greater our voice and influence and most importantly the more benefit we can be to our members

    Who adds capacitors to their power train

    Current draw is not necassarily the issue. Rapid changes in current can also cause the issue and this is where MRs can exacerbate the problem as far as I can tell. Ben, I guess you havent added them because on the S800 there isnt the space and one would hope (perhaps a little bit...

    First UK conviction for illegal use of an unmanned aircraft by the CAA.

    The fact that they are BNUC-S qualified is a bit alarming really if it proves that they didn't have the correct permissions or if there isn't another perfectly acceptable explanation. I will have to check on the ARPAS register to see if they are members but I am pretty sure they are not. Either...

    Who adds capacitors to their power train

    Most ESC manufacturers recommend you keeping the battery to ESC cable length under a certain amount- approx 20cm ie from where the cable exits the battery's heat shrink to the ESC. If you go over this then they recommend adding extra capacitors. So, most large MRs I have seen do not have any...

    X8 Design Study

    It seems that the ESCs are right by the motors, is that correct? If so ESCs will require a lot of extra capacitors as most ESCs do not like being far from the battery- normallly no more than about 20cm from battery terminal (not the end of the battery leads ie where the battery leads attach to...

    CAA in the UK

    Okay guys, I was at the meeting in my capacity as ARPAS UK Eu legislation rep with the CAA when we talked about the way ahead. These potential laws have NOTHING to do with Resource or EuroUSC trying to fill their pockets or indeed operators trying to keep people out but they do have EVERYTHING...

    A2 Motor Test Failure

    I meant the channels in your TX being reversed rather than the motors. If they are all correct then I wonder if your throttle end point needs lowering- perhaps the ESCs are not arming due to not seeing zero throttle. What tones are you hearing when you plug in your batts? Sent from my iPhone...

    A2 Motor Test Failure

    Apologies if I am teaching you to such eggs but in the past when people haven't been able to get the motors to start it is often because one of the channels is reversed and as a result the combo stick move doesn't work properly. Worth a check.

    dji a2 two purple flashes

    Hmmm, two purple flashes normally means that you are in GPS mode and that your sticks are not centred. If you can get a vid of what you are seeing, that would help. Have you done the combo stick move to initiate the motors?
