Posted by Jiro Hattori on June 25, 2013 at 5:40am

The EMC shielding material reduce magnetic interference that is good to ArduCpoter3.0.

Measurement of magnetic interference becomes half by 60micron meter low-loss,high permeability nano-crystalline material.

    I am going to give this a shot. I have some interference and vibration issues that Oliver pointed out. Hopefully it will be as simple as putting a piece of this under some moongel and putting the APM on top of that.

    how does this compare to, say, copper tape connected to ground?

    @Thomas,

    Thanks, but weight is really a priority:). I'm prototyping long flight duration multicopters where low weight is a key ingredient.

    @Ken,

    If you are not concerned about weight, buy the 3M sheet and do not take the backing off the adhesive side.

    Where can I buy the thin film without adhesive:)?

    The weight of the film (95mm x 55mm) is about 1.5 gram without adhesive.

    The 3M material can be purchased as thin sheets on eBay: http://www.ebay.com/itm/160613440162?ssPageName=STRK:MEWAX:IT&_...
