The camera weighs 68 grams including the two AAA batteries.
I have also got an extra battery pack to power the 555 timer, but that will change - I will add a lead to power from the rx battery pack. The plane is a little unforgiving with the extra weight, plus of course, I,m still learning to fly .The camera is suspended from elastic bands from the undercarridge bars, but is also wrapped in foam to add a bit of protection. I may add a few more pictures showing the plane and camera mount, but its very low tech! The main problem is isolating the vibration from the engine - you can see on most of the pictures a kind of (unwanted)wave effect.
