Hi all, I'm having a strange problem which only seems to occur when my gimbal H3-3D is powered on. I do all the pre-flights steps with the gimbal powered on and a gopro attached: - power on, gimbal activates and goes in the normal position - I do the calibration setup and the phantom starts blinking green indicating he's ready with gps Then I power up by pulling the sticks down and center but the phantom just blinks 3 times with a red light and doesn't start. After blinking red he goes back to the ready status with gps. Now I only have this issue when my gimbal is active. When I de-activate the gimbal by disconnecting the cable, shutdown and do the whole procedure again the phantom powers-up fine and starts it's propellers. This is driving me crazy. Sometimes I move it around a bit and suddenly he starts up, other times no luck until I de-activate the gimbal and restart the procedure with the gimbal disconnected. Anyone know what's happening?
