There are a lot of people that are having trouble figuring out what Gain settings to change and by how much to get the desired performance from there P2 when using the Stock Radio Transmitter, Zenmuse Gimbal, GoPro H3 and FPV. Myself included. This especially holds true for people using it to shoot pro video. Please only post your experiences, settings and what you have figured out with regards to the Gains Adjustment available in the P2 Assistant Software. Please just post if you are using the STOCK RADIO TRANSMITTER and your P2 has the Zenmuse H3-2D Gimbal with a GoPro Hero 3 series camera and a FPV Setup.
