I just purchased my first quad, vision 2 plus v3, and am very impressed. I have mostly planes and a heli that I have been flying for a few years. I have to say I love flying the vision. It's as easy or as fast and fun as you want it to be. The video footage is really awesome as well. To my issue, as I stated above its the new version with the gimble control on the radio. When I am controlling the gimble with the dial on the radio the movements are very jerky and fluctuate from fast to slow. When controlling the gimble through the app on my phone the movement is very stable and smooth as I would expect it to be. I have calibrated all channels on the radio via the computer applications with very liitle change. It did improve slightly after my first calibration but it still no where near the smooth movement via the phone app. i am curious if others are having this issue or if I am not calibrating it properly. Thanks In Advance for the help and for all the information I have gathered via this forum. This place has been and will continue to be a great resource for my phantom flying.
