Thanks Dave.
Yes it has the BOSS lens stabilisation.
The AV130 looks just the job. It's listed at 410g with servos and potentiometers. I think with the camera, camera battery and radian that should all still come in at less than 1kg. (just about.. maybe!!).
I noticed a while back you had a post regarding your ADX3 build and your flight weight test. You made reference to your nex 5 and 18-55mm lens being the max you would go. Do you know the weight of nex and 18-55? Looking at Sony's site both are 210g, 420g in total + battery. If so it's about the same as the CX410. I do like the ADX3 but still unsure of flight times with the CX410.
Anyhow, thanks for the advise and sorry if i've rambled a bit, just trying to work it out!
All the best
Stu.
