Which parameter for better hold in wind

Posted by Terry Brooks on July 1, 2012 at 1:34am

Hi folks

I have my APM2 set up OK(ish) it will hold position fine in a mild breeze of up to 6mph, beyond that it starts to get all over the place and cannot cope

If I wanted it to hold better in a stronger wind (say up to 15mph) like I've seen others doing what parameter/s should I look to change ?

I assume the same parameters will improve the multi's RTL ability in a wind too

Thanks

    Hi terry sorry for you to bail out so soon, if you dont want to use it for quad copter why not use it for fix wing.

    I also strugle to get my y6 going and the process here to get answers is very slow so basically you on your own if you have these electronics.

    I will try using it on my fix wing and see how it goes otherwise i will get the dji naza the nr one thing i want my quad to do is alt hold and gps hold and it seems like the naza is doing a great job.

    Arghhhhhhhhh

    Had enough now

    Upgraded to 2.6 and mav 1.0 and find that I have to re do all the PID stuff

    Don't have Xbee or telemetry so it's a very slow process and just can't be bothered

    Also discovered during trying to do the PID's with 2.6 that the alt hold has changed and as soon as you click to Loiter you have to very quickly set the throttle to 50% stick otherwise it will fall like a brick and break the landing gear :( not impressed

    Anyone in the UK want to buy my APM2 it's £150 plus postage

    Wow, no help whatsoever

    Such a shame as it's a great piece of kit otherwise

    Anyone want to buy a hardly used APM 2 mounted on an X650 frame with Turnigy Plush 25-30a esc's, original XA motors with APC 12 x 3.8 props and a Goodluckbuy 2 axis camera gimbal with servos (plus shutter trigger and servo)

    All you'd need is your receiver and battery

    I am probably one of many following this thread with interest ?? as I am currently trying to tune a Hexa. 

    It is definitely more a black art than a science, as slight changes can have unexpected results.

    Today I managed some good flights in a mild breeze (5 to 7 kts) with a loiter of 10m radius, increasing the IMAX while all else remained unchanged.

    It is till not as stable as you see about on teh net but that will obviously be an ongoing thing.

    So come on everyone, us newbies need the input and sharing, even if yours is not working as expected that may be useful to some of us before we go down that path.

    So anyone ?

    Seriously still nobody to answer this ?

    Do you know this? There you can simulate different wind speeds to find the best PIDs.

    Morning,

    I find that members very seldom respond to Loiter PID type settings.  I feel like either its be biggest secret ever and no one wants to share or alternativly members are not quite sure how they got their loiter as tight as they did as so don't really want to put their ideas out there.

    My loiter is setup and stays in a 5x5m box, but when I posed the question with a relevant amount of details and even bumped my topic there were no responses...

     

    Would be nice if someone could assist with these types of questions.  Please see my post here.

    Good luck.

     

    James
