I dont think weight is the main issue it should be no more then 50g, finding room inside may be a problem. Last I saw the osd mk2 only worked with wookong m currently at least that was of a few days ago. The mk1 osd did work with naza m and phantom though I havent seen it for sale anywhere.
I do want osd as having heading, home direction, voltage and altitude would be great for fpv flying. The dji osd looks good and doesnt require more sensors like other solutions need so overall lower weight. I am really starting to overload my phantom and my f450 upgrade kay be needed sooner then I think.
