"it looks like you have to re balance every time you change a focal length if using a zoom how long does to take to re balance?" FOV should only effect the tilt so perhaps 20 seconds to adjust. I'm also hoping there is an acceptable range that the tilt can tolerate so we can make FOV changes on the multirotor without having to land/adjust. Cheers, Jeff
Can't help but see the irony in you handling one before purchasing since most that actually DID buy them havn't held one yet
