RE: mini camera for slo v
The Flycamone v2 is so light that it hardly affects the loading on the plane.
In practise you really don't need the weight of a RF transmitter if you are interested in taking videos.
If you want a mini UAV, things are different, but you can get your feet wet at minimal expense with the FlycamOne.
After doing so, I'm very glad that I didn't spend the money on a more expensive RF rig, as I found that my interest was satiated by the little camera.
Cameras work BEST on electrics because of the lower vibration levels.
