LC Filter

[Pasty]

I like the recycle idea... off to the loft for me! :)

Have you tried them yet?

[Badlands]

Yes - fitted one to my GPS unit (torroid only).

Works really well, sometimes i was waiting 20 mins to get a GPS lock - now from cold i have GPS lock in 90 seconds.




Ive added one to my Steathwing & will report back the results once its finished.

thanks for that coyote i made one and it has improved my video,i will fit one on all now

[Coyote]

Most welcome, they are really effective arnt they :)

Running the whole system from one lipo is in my oppinion better than two. Once its filtered if needed its fine.

I got lost a bit with the rest, do you have diagrams of the more complex filters ? If so then yes please do post them up :)

Which diagram do you want me to post, the one for your system ?

Hi all, ive deceided to put an LC filter in my easystar set up that uses an ezosd.

I will put the ferrite ring in then the capacitor on the power / video in lead. Is there any point adding a ferrite ring on the video out lead to the camera?

Thanks

Hi,
better will be to use 10-47 nF in place of last 100 uF. Diode - any Schottky type switching diode.

Other idea - in place of ferrite ring - put 10 uH axial inductor with size proper to you current.

Using LC-filters  = 10 uH axial inductors + 10-47 nF capacacitors, are very good and cheap solution for protecting all servo signal lines (specially when you use extending cables).

 These filters are good

Power everything bar escs through one of these. So, basically take power off for all your onboard FPV kit/ BEC after the current sensor through the filter. As with all current sensors do NOT use the GND and + wires, just the current sense output. ;D (big discussion on this by Ren on RC Groups)

Here mine for long range Skywalker with 4s 10000mah, tapping 3s power for VTX and Camera.

Nice work lads, have you noticed any difference ?

[Chris R]

Will let you know when tested.  ;)

[mark1975]

Yeah me too..not had chance to test yet ''but soon.

[Chris R]

Ok tested LC filter and 99% of interference is gone. :)
